Research Paper

Definition:

Research Paper is a written document that presents the author’s original research, analysis, and interpretation of a specific topic or issue.

It is typically based on Empirical Evidence, and may involve qualitative or quantitative research methods, or a combination of both. The purpose of a research paper is to contribute new knowledge or insights to a particular field of study, and to demonstrate the author’s understanding of the existing literature and theories related to the topic.

Structure of Research Paper

The structure of a research paper typically follows a standard format, consisting of several sections that convey specific information about the research study. The following is a detailed explanation of the structure of a research paper:

The title page contains the title of the paper, the name(s) of the author(s), and the affiliation(s) of the author(s). It also includes the date of submission and possibly, the name of the journal or conference where the paper is to be published.

The abstract is a brief summary of the research paper, typically ranging from 100 to 250 words. It should include the research question, the methods used, the key findings, and the implications of the results. The abstract should be written in a concise and clear manner to allow readers to quickly grasp the essence of the research.

Introduction

The introduction section of a research paper provides background information about the research problem, the research question, and the research objectives. It also outlines the significance of the research, the research gap that it aims to fill, and the approach taken to address the research question. Finally, the introduction section ends with a clear statement of the research hypothesis or research question.

Literature Review

The literature review section of a research paper provides an overview of the existing literature on the topic of study. It includes a critical analysis and synthesis of the literature, highlighting the key concepts, themes, and debates. The literature review should also demonstrate the research gap and how the current study seeks to address it.

The methods section of a research paper describes the research design, the sample selection, the data collection and analysis procedures, and the statistical methods used to analyze the data. This section should provide sufficient detail for other researchers to replicate the study.

The results section presents the findings of the research, using tables, graphs, and figures to illustrate the data. The findings should be presented in a clear and concise manner, with reference to the research question and hypothesis.

The discussion section of a research paper interprets the findings and discusses their implications for the research question, the literature review, and the field of study. It should also address the limitations of the study and suggest future research directions.

The conclusion section summarizes the main findings of the study, restates the research question and hypothesis, and provides a final reflection on the significance of the research.

The references section provides a list of all the sources cited in the paper, following a specific citation style such as APA, MLA or Chicago.

How to Write Research Paper

You can write Research Paper by the following guide:

• Choose a Topic: The first step is to select a topic that interests you and is relevant to your field of study. Brainstorm ideas and narrow down to a research question that is specific and researchable.
• Conduct a Literature Review: The literature review helps you identify the gap in the existing research and provides a basis for your research question. It also helps you to develop a theoretical framework and research hypothesis.
• Develop a Thesis Statement : The thesis statement is the main argument of your research paper. It should be clear, concise and specific to your research question.
• Plan your Research: Develop a research plan that outlines the methods, data sources, and data analysis procedures. This will help you to collect and analyze data effectively.
• Collect and Analyze Data: Collect data using various methods such as surveys, interviews, observations, or experiments. Analyze data using statistical tools or other qualitative methods.
• Organize your Paper : Organize your paper into sections such as Introduction, Literature Review, Methods, Results, Discussion, and Conclusion. Ensure that each section is coherent and follows a logical flow.
• Write your Paper : Start by writing the introduction, followed by the literature review, methods, results, discussion, and conclusion. Ensure that your writing is clear, concise, and follows the required formatting and citation styles.
• Edit and Proofread your Paper: Review your paper for grammar and spelling errors, and ensure that it is well-structured and easy to read. Ask someone else to review your paper to get feedback and suggestions for improvement.
• Cite your Sources: Ensure that you properly cite all sources used in your research paper. This is essential for giving credit to the original authors and avoiding plagiarism.

Title: The Impact of Social Media on Mental Health among Young Adults

Abstract: This study aims to investigate the impact of social media use on the mental health of young adults. A literature review was conducted to examine the existing research on the topic. A survey was then administered to 200 university students to collect data on their social media use, mental health status, and perceived impact of social media on their mental health. The results showed that social media use is positively associated with depression, anxiety, and stress. The study also found that social comparison, cyberbullying, and FOMO (Fear of Missing Out) are significant predictors of mental health problems among young adults.

Introduction: Social media has become an integral part of modern life, particularly among young adults. While social media has many benefits, including increased communication and social connectivity, it has also been associated with negative outcomes, such as addiction, cyberbullying, and mental health problems. This study aims to investigate the impact of social media use on the mental health of young adults.

Literature Review: The literature review highlights the existing research on the impact of social media use on mental health. The review shows that social media use is associated with depression, anxiety, stress, and other mental health problems. The review also identifies the factors that contribute to the negative impact of social media, including social comparison, cyberbullying, and FOMO.

Methods : A survey was administered to 200 university students to collect data on their social media use, mental health status, and perceived impact of social media on their mental health. The survey included questions on social media use, mental health status (measured using the DASS-21), and perceived impact of social media on their mental health. Data were analyzed using descriptive statistics and regression analysis.

Results : The results showed that social media use is positively associated with depression, anxiety, and stress. The study also found that social comparison, cyberbullying, and FOMO are significant predictors of mental health problems among young adults.

Discussion : The study’s findings suggest that social media use has a negative impact on the mental health of young adults. The study highlights the need for interventions that address the factors contributing to the negative impact of social media, such as social comparison, cyberbullying, and FOMO.

Conclusion : In conclusion, social media use has a significant impact on the mental health of young adults. The study’s findings underscore the need for interventions that promote healthy social media use and address the negative outcomes associated with social media use. Future research can explore the effectiveness of interventions aimed at reducing the negative impact of social media on mental health. Additionally, longitudinal studies can investigate the long-term effects of social media use on mental health.

Limitations : The study has some limitations, including the use of self-report measures and a cross-sectional design. The use of self-report measures may result in biased responses, and a cross-sectional design limits the ability to establish causality.

Implications: The study’s findings have implications for mental health professionals, educators, and policymakers. Mental health professionals can use the findings to develop interventions that address the negative impact of social media use on mental health. Educators can incorporate social media literacy into their curriculum to promote healthy social media use among young adults. Policymakers can use the findings to develop policies that protect young adults from the negative outcomes associated with social media use.

They can facilitate interdisciplinary collaborations and partnerships that can lead to innovative solutions to complex problems.

When to Write Research Paper

Research papers are typically written when a person has completed a research project or when they have conducted a study and have obtained data or findings that they want to share with the academic or professional community. Research papers are usually written in academic settings, such as universities, but they can also be written in professional settings, such as research organizations, government agencies, or private companies.

Here are some common situations where a person might need to write a research paper:

• For academic purposes: Students in universities and colleges are often required to write research papers as part of their coursework, particularly in the social sciences, natural sciences, and humanities. Writing research papers helps students to develop research skills, critical thinking skills, and academic writing skills.
• For publication: Researchers often write research papers to publish their findings in academic journals or to present their work at academic conferences. Publishing research papers is an important way to disseminate research findings to the academic community and to establish oneself as an expert in a particular field.
• To inform policy or practice : Researchers may write research papers to inform policy decisions or to improve practice in various fields. Research findings can be used to inform the development of policies, guidelines, and best practices that can improve outcomes for individuals and organizations.
• To share new insights or ideas: Researchers may write research papers to share new insights or ideas with the academic or professional community. They may present new theories, propose new research methods, or challenge existing paradigms in their field.

Purpose of Research Paper

The purpose of a research paper is to present the results of a study or investigation in a clear, concise, and structured manner. Research papers are written to communicate new knowledge, ideas, or findings to a specific audience, such as researchers, scholars, practitioners, or policymakers. The primary purposes of a research paper are:

• To contribute to the body of knowledge : Research papers aim to add new knowledge or insights to a particular field or discipline. They do this by reporting the results of empirical studies, reviewing and synthesizing existing literature, proposing new theories, or providing new perspectives on a topic.
• To inform or persuade: Research papers are written to inform or persuade the reader about a particular issue, topic, or phenomenon. They present evidence and arguments to support their claims and seek to persuade the reader of the validity of their findings or recommendations.
• To advance the field: Research papers seek to advance the field or discipline by identifying gaps in knowledge, proposing new research questions or approaches, or challenging existing assumptions or paradigms. They aim to contribute to ongoing debates and discussions within a field and to stimulate further research and inquiry.

How To Write A Research Paper

Step-By-Step Tutorial With Examples + FREE Template

By: Derek Jansen (MBA) | Expert Reviewer: Dr Eunice Rautenbach | March 2024

For many students, crafting a strong research paper from scratch can feel like a daunting task – and rightly so! In this post, we’ll unpack what a research paper is, what it needs to do , and how to write one – in three easy steps. 🙂 

Overview: Writing A Research Paper

What (exactly) is a research paper.

• How to write a research paper
• Stage 1 : Topic & literature search
• Stage 2 : Structure & outline
• Stage 3 : Iterative writing
• Key takeaways

Let’s start by asking the most important question, “ What is a research paper? ”.

Simply put, a research paper is a scholarly written work where the writer (that’s you!) answers a specific question (this is called a research question ) through evidence-based arguments . Evidence-based is the keyword here. In other words, a research paper is different from an essay or other writing assignments that draw from the writer’s personal opinions or experiences. With a research paper, it’s all about building your arguments based on evidence (we’ll talk more about that evidence a little later).

Now, it’s worth noting that there are many different types of research papers , including analytical papers (the type I just described), argumentative papers, and interpretative papers. Here, we’ll focus on analytical papers , as these are some of the most common – but if you’re keen to learn about other types of research papers, be sure to check out the rest of the blog .

With that basic foundation laid, let’s get down to business and look at how to write a research paper .

Overview: The 3-Stage Process

While there are, of course, many potential approaches you can take to write a research paper, there are typically three stages to the writing process. So, in this tutorial, we’ll present a straightforward three-step process that we use when working with students at Grad Coach.

These three steps are:

• Finding a research topic and reviewing the existing literature
• Developing a provisional structure and outline for your paper, and
• Writing up your initial draft and then refining it iteratively

Let’s dig into each of these.

Need a helping hand?

Step 1: Find a topic and review the literature

As we mentioned earlier, in a research paper, you, as the researcher, will try to answer a question . More specifically, that’s called a research question , and it sets the direction of your entire paper. What’s important to understand though is that you’ll need to answer that research question with the help of high-quality sources – for example, journal articles, government reports, case studies, and so on. We’ll circle back to this in a minute.

The first stage of the research process is deciding on what your research question will be and then reviewing the existing literature (in other words, past studies and papers) to see what they say about that specific research question. In some cases, your professor may provide you with a predetermined research question (or set of questions). However, in many cases, you’ll need to find your own research question within a certain topic area.

Finding a strong research question hinges on identifying a meaningful research gap – in other words, an area that’s lacking in existing research. There’s a lot to unpack here, so if you wanna learn more, check out the plain-language explainer video below.

Once you’ve figured out which question (or questions) you’ll attempt to answer in your research paper, you’ll need to do a deep dive into the existing literature – this is called a “ literature search ”. Again, there are many ways to go about this, but your most likely starting point will be Google Scholar .

If you’re new to Google Scholar, think of it as Google for the academic world. You can start by simply entering a few different keywords that are relevant to your research question and it will then present a host of articles for you to review. What you want to pay close attention to here is the number of citations for each paper – the more citations a paper has, the more credible it is (generally speaking – there are some exceptions, of course).

Ideally, what you’re looking for are well-cited papers that are highly relevant to your topic. That said, keep in mind that citations are a cumulative metric , so older papers will often have more citations than newer papers – just because they’ve been around for longer. So, don’t fixate on this metric in isolation – relevance and recency are also very important.

Beyond Google Scholar, you’ll also definitely want to check out academic databases and aggregators such as Science Direct, PubMed, JStor and so on. These will often overlap with the results that you find in Google Scholar, but they can also reveal some hidden gems – so, be sure to check them out.

Once you’ve worked your way through all the literature, you’ll want to catalogue all this information in some sort of spreadsheet so that you can easily recall who said what, when and within what context. If you’d like, we’ve got a free literature spreadsheet that helps you do exactly that.

Step 2: Develop a structure and outline

With your research question pinned down and your literature digested and catalogued, it’s time to move on to planning your actual research paper .

It might sound obvious, but it’s really important to have some sort of rough outline in place before you start writing your paper. So often, we see students eagerly rushing into the writing phase, only to land up with a disjointed research paper that rambles on in multiple

Now, the secret here is to not get caught up in the fine details . Realistically, all you need at this stage is a bullet-point list that describes (in broad strokes) what you’ll discuss and in what order. It’s also useful to remember that you’re not glued to this outline – in all likelihood, you’ll chop and change some sections once you start writing, and that’s perfectly okay. What’s important is that you have some sort of roadmap in place from the start.

At this stage you might be wondering, “ But how should I structure my research paper? ”. Well, there’s no one-size-fits-all solution here, but in general, a research paper will consist of a few relatively standardised components:

• Introduction
• Literature review
• Methodology

Let’s take a look at each of these.

First up is the introduction section . As the name suggests, the purpose of the introduction is to set the scene for your research paper. There are usually (at least) four ingredients that go into this section – these are the background to the topic, the research problem and resultant research question , and the justification or rationale. If you’re interested, the video below unpacks the introduction section in more detail. 

The next section of your research paper will typically be your literature review . Remember all that literature you worked through earlier? Well, this is where you’ll present your interpretation of all that content . You’ll do this by writing about recent trends, developments, and arguments within the literature – but more specifically, those that are relevant to your research question . The literature review can oftentimes seem a little daunting, even to seasoned researchers, so be sure to check out our extensive collection of literature review content here .

With the introduction and lit review out of the way, the next section of your paper is the research methodology . In a nutshell, the methodology section should describe to your reader what you did (beyond just reviewing the existing literature) to answer your research question. For example, what data did you collect, how did you collect that data, how did you analyse that data and so on? For each choice, you’ll also need to justify why you chose to do it that way, and what the strengths and weaknesses of your approach were.

Now, it’s worth mentioning that for some research papers, this aspect of the project may be a lot simpler . For example, you may only need to draw on secondary sources (in other words, existing data sets). In some cases, you may just be asked to draw your conclusions from the literature search itself (in other words, there may be no data analysis at all). But, if you are required to collect and analyse data, you’ll need to pay a lot of attention to the methodology section. The video below provides an example of what the methodology section might look like.

By this stage of your paper, you will have explained what your research question is, what the existing literature has to say about that question, and how you analysed additional data to try to answer your question. So, the natural next step is to present your analysis of that data . This section is usually called the “results” or “analysis” section and this is where you’ll showcase your findings.

Depending on your school’s requirements, you may need to present and interpret the data in one section – or you might split the presentation and the interpretation into two sections. In the latter case, your “results” section will just describe the data, and the “discussion” is where you’ll interpret that data and explicitly link your analysis back to your research question. If you’re not sure which approach to take, check in with your professor or take a look at past papers to see what the norms are for your programme.

Alright – once you’ve presented and discussed your results, it’s time to wrap it up . This usually takes the form of the “ conclusion ” section. In the conclusion, you’ll need to highlight the key takeaways from your study and close the loop by explicitly answering your research question. Again, the exact requirements here will vary depending on your programme (and you may not even need a conclusion section at all) – so be sure to check with your professor if you’re unsure.

Step 3: Write and refine

Finally, it’s time to get writing. All too often though, students hit a brick wall right about here… So, how do you avoid this happening to you?

Well, there’s a lot to be said when it comes to writing a research paper (or any sort of academic piece), but we’ll share three practical tips to help you get started.

First and foremost , it’s essential to approach your writing as an iterative process. In other words, you need to start with a really messy first draft and then polish it over multiple rounds of editing. Don’t waste your time trying to write a perfect research paper in one go. Instead, take the pressure off yourself by adopting an iterative approach.

Secondly , it’s important to always lean towards critical writing , rather than descriptive writing. What does this mean? Well, at the simplest level, descriptive writing focuses on the “ what ”, while critical writing digs into the “ so what ” – in other words, the implications . If you’re not familiar with these two types of writing, don’t worry! You can find a plain-language explanation here.

Last but not least, you’ll need to get your referencing right. Specifically, you’ll need to provide credible, correctly formatted citations for the statements you make. We see students making referencing mistakes all the time and it costs them dearly. The good news is that you can easily avoid this by using a simple reference manager . If you don’t have one, check out our video about Mendeley, an easy (and free) reference management tool that you can start using today.

Recap: Key Takeaways

We’ve covered a lot of ground here. To recap, the three steps to writing a high-quality research paper are:

• To choose a research question and review the literature
• To plan your paper structure and draft an outline
• To take an iterative approach to writing, focusing on critical writing and strong referencing

Background: Energy and sports drinks have gained popularity among diverse demographic groups, including adolescents, athletes, workers, and college students. While often used interchangeably, these beverages serve distinct purposes, with energy drinks aiming to boost energy and cognitive performance, and sports drinks designed to prevent dehydration and replenish electrolytes and carbohydrates lost during physical exertion.

Objective: To assess the nutritional quality of energy and sports drinks in Egypt.

Material and Methods: A cross-sectional study assessed the nutrient contents, including energy, sugar, electrolytes, vitamins, and caffeine, of sports and energy drinks available in major supermarkets in Cairo, Alexandria, and Giza, Egypt. Data collection involved photographing all relevant product labels and recording nutritional information. Descriptive statistics and appropriate statistical tests were employed to analyze and compare the nutritional values of energy and sports drinks.

Results: The study analyzed 38 sports drinks and 42 energy drinks. Sports drinks were significantly more expensive than energy drinks, with higher net content and elevated magnesium, potassium, and vitamin C. Energy drinks contained higher concentrations of caffeine, sugars, and vitamins B2, B3, and B6.

Conclusion: Significant nutritional differences exist between sports and energy drinks, reflecting their intended uses. However, these beverages’ high sugar content and calorie loads raise health concerns. Proper labeling, public awareness, and responsible marketing are essential to guide safe consumption practices in Egypt.

How Many Paragraphs in an Essay?

As a rule, you’ll write your essay in three main parts. First, you’ll introduce your topic to your reader. Next, you will have body text in which you discuss the topic in more detail, and finally, you’ll have a conclusion that tells your reader what you were able to see after looking into the facts or thinking through the topic.

In its simplest form, an essay can consist of three paragraphs with one paragraph being devoted to each section. Proponents of the five paragraph essay say that the body text should consist of three paragraphs, but in reality, it’s fine to write more or fewer paragraphs in this section.

Guessing How Many Paragraphs Before You Begin

This is a rule of thumb, which means it won’t always work quite that way, but it’s handy all the same. In academic work, your paragraphs are likely to be a bit longer than most of the ones you see in this blog post. On average, there are usually 100 to 200 words in a paragraph . So if you’d like a guesstimate, you can assume that a 1,000-word essay will have between five and ten paragraphs.

What Points Do You Have to Cover?

Another, less limiting and more accurate way to work out how many paragraphs you need to cover your topic is to look at the main points you have to cover in the body text. A paragraph contains all the ideas that support or explain a single concept.

When you are planning your essay, you will think of or research the main elements that are needed in the body text. It would be safe to assume you need at least one paragraph for each of these. Of course, if there is a lot of information to cover in order to explore each area, you may need more.

For example, if you are writing an essay on childhood development and exposure to technology, you will want to look into the physical, psychological and cognitive developmental effects of tech on kids. When you research this topic, you will find that there are contrasting points of view and researchers have identified several physical, developmental, and psychological effects of technology use in children.

Assuming five psychological effects have been identified, you can assume you’ll need to write five paragraphs if you are going to write a relatively in-depth essay. But if both those who say technology is bad for kids and those who say it can be good have done a great deal of work on the sub-topic, you might want to make that ten paragraphs so that you can cover both sides of the argument and look into how earlier authors reached their conclusions.

Of course, if you have been set a relatively short word limit , you may not be able to go in-depth at all, in which case a paragraph for each of the main sub-topics (psychology, physical development, and cognitive development) will likely be adequate.

Essay Content Is More Important Than the Number of Paragraphs

Ultimately, your essay will be evaluated on the information you present, not on the number of paragraphs in the essay. Early in your academic life, teachers and lecturers may give you both a structure for your essay and a guideline on how long each part of the essay should be. I have seen essay instructions say how many marks are allocated for each section, and my trick is to take the total word count and allocate a percentage of words to each section based on the percentage of marks you can get for it. After all, if the teacher is allocating 80 marks for content in total and you can see 50% of the mark relates to a certain part of the essay, then 50% of your essay’s words should be devoted to that section.

Sometimes, you’ll just be given a topic and told to air your opinion. This gives you more freedom, but it’s a tad more difficult. The research will show you how many angles you should look at, and it’ll help you to find information that both supports and contradicts your point of view. To make a strong argument, you need to look at both supporting and contradictory information.

To avoid getting tangled up in one aspect of the discussion, you’ll have to decide how long it should be. If it’s the most important aspect informing your conclusion, you can spend a little more time (and words) on that particular point. It could run into several paragraphs rather than just one or two.

Always Remember the Purpose of Paragraphs

Paragraphs structure information into sub-topics, and they make your work easier to read and understand thanks to the structure they provide. With careful advance planning, you’ll be able to work out more or less how many paragraphs you need to complete your essay.

How many paragraphs is…

For those looking for a general rule-of-thumb, below are some estimates on the number of paragraphs there would be in an essay of different lengths based on an average length of 150 words per paragraph. Of course, the number of paragraphs for your essay will depend on many different factors. You can use the following information for a general reference, but don’t take these numbers as literal. .

Basic Essay Word to Paragraphs Conversions

• A 100 word essay is 3 paragraph. (minimum for an essay)
• A 200 word essay is 3 paragraphs. (minimum for an essay)
• A 250 word essay is 3 paragraphs. (minimum for an essay)
• A 300 word essay is 3 paragraphs. (minimum for an essay)
• A 400 word essay is 3 paragraphs. (minimum for an essay)
• A 500 word essay is 3 to 4 paragraphs.
• A 600 word essay is 4 paragraphs.
• A 700 word essay is 4 to 5 paragraphs.
• A 750 word essay is 5 paragraphs.
• A 800 word essay is 5 to 6 paragraphs.
• A 900 word essay is 6 paragraphs.
• A 1,000 word essay is 6 to 7 paragraphs.
• A 1,250 word essay is 8 to 9 paragraphs.
• A 1,500 word essay is 10 paragraphs.
• A 1,750 word essay is 11 to 12 paragraphs.
• A 2,000 word essay is 13 to 14 paragraphs.
• A 2,500 word essay is 16 to 17 paragraphs.
• A 3,000 word essay is 20 paragraphs.
• A 4,000 word essay is 26 to 27 paragraphs.
• A 5,000 word essay is 33 to 34 paragraphs.
• A 6,000 word essay is 40 paragraphs.
• A 7,000 word essay is 46 to 37 paragraphs.
• A 7,500 word essay is 50 paragraphs.
• A 8,000 word essay is 53 to 54 paragraphs.
• A 9,000 word essay is 60 paragraphs.
• A 10,000 word essay is 66 to 67 paragraphs.

I don’t understand, How can a 100, 200, 300 and 400 word essay all have 3 paragraphs if a paragraph is 100 to 200 words long? A 100 word essay should be 1 paragraph or 1/2 a paragraph, not 3 paragraphs. Can someone explain this too me?

A sentence is an idea. A paragraph is a group of ideas that relate to one another. That’s the most important point. The second most important one is remembering that your text consists of introduction, body, conclusion with at LEAST one paragraph for each. While teachers like 100 to 200 word paragraphs, you can’t always apply that. Call it a guideline rather than a rule!

the general rule is that 3 paragraphs are minimum for an essay. So, no matter how short your essay is, you should still need 3 paragraphs. If you are really for some reason writing a 100 word essay, then you should have one short sentence for both your introduction and conclusion.

I was always taught an essay has five paragraphs by my teachers. Did they lie to me? If an essay only needs three paragraphs, why would my teachers tell me that they should have five?

I think the five paragraphs for an essay is more of a rule-of-thumb number that is easy to teach students when they are first learning to write. Your teacher was just trying to make sure you understood how to write, not give you a rule you had to always obey.

I think five paragraphs is a good number to shoot for when writing, but it isn’t a hard-fast rule you need to hit every time. Each essay is different and require more or less paragraphs depending on the information you need to provide in the writing.

yes and no.. i would say a good on as 4 paragraph. Intro, 2 body P, and a conclusion.

My teachers always taught by eight paragraph essays, but five-paragraph essays normally lie precedent to the more advanced or larger essays.

I was taught essays should be 7 paragraphs long, not 5. My teacher said 3 central paragraphs never gives enough detail to the topic, so we should write 5. It makes sense to me and that is how I’ve always done it.

What you’re taught is often a general rule to shoot for, not a rule set in concrete. That’s the case with this. Your teacher felt that 7 paragraphs was a good number for the essays you wrote for her, but it doesn’t always have to be that way. it’s a general rule, not a concrete one.

How many sentences if we don’t know how many sentences we need to write?

The average paragraph contains 5-6 sentences. If you’re feeling a little extra, paragraphs can be 7-10 sentences.

It also depends on whether or not you are bringing outside information into the paragraph as well. Using quotes makes a paragraph longer than not doing so.

I think the length of a paper depends mainly on the instructions given by the instructor. Secondly, I would decide a paper length on the basis of the grading rubric.

I already knew an essay has three paragraphs

Inilividual project: follow all steps and develop a paragraph of your choice and write all expository essay with not less than 500 words of the povoloped paragraph?

On average for a five-paragraph essay, I write around 1,000-1300 words. For an eight paragraph essay, I write around 2,000-2,600 words on the document. Keep in mind your quotes too, you should have one quote per paragraph (expected) or two (recommended). It really is up to the person though, I have a buddy who writes considerably less than I do, but is able to get his point across. It is really up to the person.

Student A: Sir, do we have to write a long essay?

How will I determine my word count for 1300 to 1500 maximum words in the academic writing?

How Many Paragraphs Should an Essay Have?

• 6-minute read
• 19th May 2023

You have an essay to write. You’ve researched the topic and crafted a strong thesis statement . Now it’s time to open the laptop and start tapping away on the keyboard. You know the required word count, but you’re unsure of one thing: How many paragraphs should you have in the essay? Gee, it would’ve been nice if your professor had specified that, huh?

No worries, friend, because in this post, we’ll provide a guide to how many paragraphs an essay should have . Generally, the number of paragraphs will depend on how many words and how many supporting details you need (more on that later). We’ll also explore the concept of paragraphs if you’re wondering what they’re all about. And remember, paragraphs serve a purpose. You can’t submit an essay without using them!

What Is a Paragraph?

You likely know what a paragraph is, but can you define it properly in plain English? Don’t feel bad if that question made you shake your head. Off the top of our heads, many of us can’t explain what a paragraph is .

A paragraph comprises at least five sentences about a particular topic. A paragraph must begin with a well-crafted topic sentence , which is then followed by ideas that support that sentence. To move the essay forward, the paragraph should flow well, and the sentences should be relevant.

Why Are Paragraphs Important?

Paragraphs expand on points you make about a topic, painting a vivid picture for the reader. Paragraphs break down information into chunks, which are easier to read than one giant, uninterrupted body of text. If your essay doesn’t use paragraphs, it likely won’t earn a good grade!

 How Many Paragraphs Are in an Essay?

As mentioned, the number of paragraphs will depend on the word count and the quantity of supporting ideas required. However, if you have to write at least 1,000 words, you should aim for at least five paragraphs. Every essay should have an introduction and a conclusion. The reader needs to get a basic introduction to the topic and understand your thesis statement. They must also see key takeaway points at the end of the essay.

As a rule, a five-paragraph essay would look like this:

• Introduction (with thesis statement)
• Main idea 1 (with supporting details)
• Main idea 2 (with supporting details)
• Main idea 3 (with supporting details)

Your supporting details should include material (such as quotations or facts) from credible sources when writing the main idea paragraphs.

If you think your essay could benefit from having more than five paragraphs, add them! Just make sure they’re relevant to the topic.

Professors don’t care so much about the number of paragraphs; they want you to satisfy the minimum word requirement. Assignment rubrics rarely state the number of required paragraphs. It will be up to you to decide how many to write, and we urge you to research the assigned topic before writing the essay. Your main ideas from the research will generate most of the paragraphs.

When Should I Start a New Paragraph?

Surprisingly, some students aren’t aware that they should break up some of the paragraphs in their essays . You need to start new paragraphs to keep your reader engaged.

As well as starting a new paragraph after the introduction and another for the conclusion, you should do so when you’re introducing a new idea or presenting contrasting information.

Starting a paragraph often involves using transitional words or phrases to signal to the reader that you’re presenting a new idea. Failing to use these cues may cause confusion for the reader and undermine your essay’s coherence.

Let’s consider examples of transitional words and phrases in action in a conclusion. Note that the essay is about too much mobile device screen time and that transitional words and phrases can occur later in a paragraph too:

Thanks to “In conclusion” and “Additionally,” the reader clearly knows that they are now in the conclusion stage. They can also follow the logic and development of the essay more easily.

How Do I Know Whether I Have Enough Paragraphs?

While no magic number exists for how many paragraphs you need, you should know when you have enough to satisfy the requirements of the assignment. It helps if you can answer yes to the following questions:

• Does my essay have both an introduction and a conclusion?
• Have I provided enough main ideas with supporting details, including quotes and cited information?
• Does my essay develop the thesis statement?
• Does my essay adequately inform the reader about the topic?
• Have I provided at least one takeaway for the reader?

 Conclusion

Professors aren’t necessarily looking for a specific number of paragraphs in an essay; it’s the word count that matters. You should see the word count as a guide for a suitable number of paragraphs. As a rule, five paragraphs should suffice for a 1,000-word essay. As long as you have an introduction and a conclusion and provide enough supporting details for the main ideas in your body paragraphs, you should be good to go.

Remember to start a new paragraph when introducing new ideas or presenting contrasting information. Your reader needs to be able to follow the essay throughout, and a single, unbroken block of text would be difficult to read. Transitional words and phrases help start new paragraphs, so don’t forget to use them!

As with any writing, we always recommend proofreading your essay after you’ve finished it. This step will help to detect typos, extra spacing, and grammatical errors. A second pair of eyes is always useful, so we recommend asking our proofreading experts to review your essay . They’ll correct your grammar, ensure perfect spelling, and offer suggestions to improve your essay. You can even submit a 500-word document for free!

1. What is a paragraph and what is its purpose?

A paragraph is a group of sentences that expand on a single idea. The purpose of a paragraph is to introduce an idea and then develop it with supporting details.

2. What are the benefits of paragraphs?

Paragraphs make your essay easy to read by providing structure and flow. They let you transition from one idea to another. New paragraphs allow you to tell your reader that you’ve covered one point and are moving on to the next.

3. How many paragraphs does a typical essay have?

An essay of at least 1,000 words usually has five paragraphs. It’s best to use the required word count as a guide to the number of paragraphs you’ll need.

How Many Paragraphs in a Research Paper: Steps on How to Write

Paragraphs In Research Paper

A research paper is an essay where after exploring a particular topic thoroughly, you can write a detailed essay about it.

In as much as you are allowed to use your thoughts, opinions, ideas, and knowledge, you must also include information from sources, books, journals, internet sites, and interviews in your research.

Therefore, at least 80% of the research paper should be written in your own words. Paragraphs must be detailed and arranged in order to maintain the flow of the essay, with each explaining a new point or contribution.

How Many Body Paragraphs Should a Research Paper Have?

The number of body paragraphs in a research paper depends on the length of the research paper. Some instructors usually hand out a specific length for research papers.

With each paragraph containing five to six sentences, each page should have three paragraphs.

Therefore, a three-page research paper should have nine paragraphs, and a ten-page research paper should have at least 30 paragraphs.

However, some research papers may require longer paragraphs where two paragraphs are enough for every page. As such, a three-page essay and a ten-page essay should have six and twenty paragraphs, respectively.

The paragraphs should always be proportional to your paper length, with shorter paragraphs in short research papers and longer paragraphs in long research paragraphs.

Types of Paragraphs in a Research Paper

1. introduction paragraph.

This is the paragraph where you set up the topic of the paper and the way you are approaching it to the reader. First, you have to introduce the topic. You have to tell the reader what you are writing about using a hooking sentence.

This sentence should grab the attention of the reader and convey the relevance of your topic. Secondly, you have to describe the background of the topic. This usually depends on the approach you are using in your paper and is mostly used in argumentative research.

It is where you review previous research and reveal how yours will fit in.

Thirdly is establishing your research problem. After showing how your research fits in, show the problems it addresses too.

Fourthly, you will have to specify the objectives of your paper. This is what you intend to find out and express in your paper.

Fifthly, you will have to include a brief overview of your paper. In a paper that uses the standard methods of research writing, it is not necessary, but if the structure is not predictable, it is important to describe it for the reader.

The last sentence in the introduction is always the thesis statement. It reveals everything the paper is all about.

2. Body Paragraphs

Arranging ideas and points in body paragraphs is a challenge for many students.

Each paragraph should always cover a different point. If two paragraphs have to explain the same thing, make sure that the approach taken in both is different.

To write a body paragraph, you will first start with a topic sentence to establish the main point of the paragraph. Reading the topic sentence in every body paragraph should provide the reader with the main points of your research.

The next task is unpacking the topic sentence. This is where you explain and discuss the individual parts of the topic sentence. After that, you give evidence to support your data. This is done by providing arguments, data, facts, figures, and quotations from credible sources .

Next, you will have to analyze the evidence. Never leave the evidence hanging. Instead, link it to the ideas you are trying to prove. Also, you will have to prove the objective by tying the body paragraph with the main topic of the research.

Finally, provide a transition to link your body paragraph to the next. The connection should be clear to maintain the flow of the paper.

3. Conclusion Paragraphs

This is the paragraph where you wrap up your thoughts and ideas and leave the reader with an impression.

The first thing to do when writing a conclusion is to remind the reader of your research problem. Paraphrase the research problem to make sure it is not identical to the one in the essay introduction.

Next, you will have to sum up the paper. Summarize what you addressed in the body of the essay and provide the conclusions they lead to. Generally, you have to summarize your overall findings.

After that, you discuss the implications. After formulating the summary of your findings, it is necessary to consider the implications of the broader research.

This is by providing the takeaways from your paper which are either practical or theoretical. For example, you can provide a reasonable call for action or suggest a research topic that is not covered in your paper.

How Many Paragraphs for Each of the Above Types?

Introduction paragraph.

A research paper’s introduction paragraphs depend on the length of the paper. If you are writing a five-page page essay, then the introduction should not take more than half of a page.

Therefore, one or two paragraphs are enough for such a paper. However, when writing a longer essay, the introduction paragraphs should be more in order to introduce everything you will talk about in the essay.

There is always an approximation that the introduction should be 10 percent of the total word count.

If you are writing an 1800-word research paper, then the introduction should be at least 180 words which translates to two introduction paragraphs.

Body Paragraphs

The shortest research paper usually has five paragraphs. Therefore, you are supposed to have three body paragraphs and one each for the introduction and conclusion.

However, this varies depending on the length of the research paper. For example, an 1800-word research paper should at least have 16 body paragraphs.

Research papers should have one or two paragraphs that summarize everything that has been written in the paper. Making it too long may lead to repetition.

However, for longer essays, more paragraphs can be required to summarize the key findings and their significance. One can also use the 10% rule. A conclusion with 10% of the total word count is proportional to the essay length.

To add to that, professional empirical research articles usually have conclusions that range from five to six paragraphs.

 On the other hand, novice and student research papers usually have two to three conclusion paragraphs.

How Long Should a Paragraph Be in a Research Paper?

The introduction paragraph of an essay should at least have five or six sentences that build up to the thesis statement at the end.

The first sentence should introduce the topic. The second should provide background information. The third should show the problem being addressed. The fourth should provide the objectives.

Lastly, the fifth should provide the overview, and the thesis statement should come last.

The body paragraphs of an essay should have six to seven sentences. These should contain sentences that introduce the main topic of the paragraph and unpack it.

Further sentences should provide evidence of the topic. Additionally, other sentences should analyze the evidence and prove the objective of the research paper. The last sentence should be a link to the body paragraph of the next

Lastly, the conclusion paragraphs should have five to six sentences. The average number of words should be between 75 to 85 words.

These paragraphs should not only be long enough to summarise your research paper but also short enough to avoid repetition of what is already written in the paper.

The sentences in the conclusion should be brief and straight to the point because there is nothing new that should be introduced. Every sentence should reflect the main idea of the essay.

A paragraph is a group of related sentences that support one main idea. In general, paragraphs consist of three parts: the topic sentence, body sentences, and the concluding or the bridge sentence to the next paragraph or section of the paper. Paragraphs show where the subdivisions of a research paper begin and end and, thus, help the reader see the organization of the essay and grasp its main points in relation to the research problem.

Importance of Constructing Good Paragraphs

Paragraphs are the building blocks of papers . Without well-written paragraphs that flow logically from one idea to the next and that inform and help support understanding of the research problem being investigated, your paper will not be viewed as credible by the reader. More than simply a collection of sentences, a paragraph must possess a controlling idea [i.e., the thinking strategy, opinion, or attitude that provides a framework from which to interpret the author’s position concerning the research problem]. The paragraph should then explain the idea in a structurally coherent way and be sufficiently developed to inform the reader about that idea in a way that transitions naturally into the next paragraph or section of your paper.

Below are common problems with developing effective paragraphs:

1.  The paragraph has no controlling idea . Imagine each paragraph as having three general layers of text. The core content is in the middle. It includes all the evidence you need to make the point. However, this evidence needs to be introduced by a topic sentence or your readers will not know what to do with all the evidence you have given them. Therefore, the beginning of the paragraph explains the controlling idea of the paragraph. The last part of the paragraph tells the reader how the paragraph relates to the broader argument and provides a transition to the next idea. Once you have mastered the use of topic sentences, you may decide that the topic sentence for a particular paragraph really should not be the first sentence of the paragraph. This is fine—the topic sentence can actually go at the beginning, middle, or end of a paragraph; what is important is that it is there to inform readers what the main idea of the paragraph is and how it relates back to the broader topic of your paper.

2.  The paragraph has more than one controlling idea . This is the most common reason why a paragraph is too lengthy. If a paragraph is more than a page long, it likely contains more than one controlling idea. In this case, consider eliminating sentences that relate to the second idea, with the thought that these statements do not inform and help support the research problem, or if this information is important, split the paragraph into two or more paragraphs, each with only one controlling idea.

3.  Transitional statement is missing . In academic writing, most paragraphs include a transition from one paragraph to the next paragraph because research writing often addresses complex and multilayered topics that require in-depth explanations and analysis. T he transition ensures that there is a logical sequence of thoughts, ideas, and arguments within y our paper. A transitional statement can be one or two sentences that helps establish relationships between controlling ideas and create a logical progression of those ideas throughout the paper. Transitions are especially important at the end of paragraphs that discuss multiple examples, explain complex issues or concepts, or at the end of each section of your paper [e.g., introduction to literature review].

University of Warwick; Hicks, Rodney W. “Tips for New and Experienced Authors: Focus on the Paragraph.” Journal of the American Association of Nurse Practitioners 32 (October 2020): 639-641.

Structure and Writing Style

I.  General Structure

Most paragraphs in an essay parallel the general three-part structure of each section of a research paper and, by extension, the overall research paper, with an introduction, a body that includes facts and analysis, and a conclusion. You can see this structure in paragraphs whether they are narrating, describing, comparing, contrasting, or analyzing information. Each part of the paragraph plays an important role in communicating the meaning you intend to covey to the reader.

Introduction : the first section of a paragraph; should include the topic sentence and any other sentences at the beginning of the paragraph that give background information or provide a transition.

Body : follows the introduction; discusses the controlling idea, using facts, arguments, analysis, examples, and other information.

Conclusion : the final section; summarizes the connections between the information discussed in the body of the paragraph and the paragraph’s controlling idea. For long paragraphs, you may also want to include a bridge sentence that introduces the next paragraph or section of the paper. In some instances, the bridge sentence can be written in the form of a question. However, use this rhetorical device sparingly, otherwise, ending a lot of paragraphs with a question to lead into the next paragraph sounds cumbersome.

NOTE:   This general structure does not imply that you should not be creative in your writing. Arranging where each element goes in a paragraph can make a paper more engaging for the reader. However, do not be too creative in experimenting with the narrative flow of paragraphs. To do so may distract from the main arguments of your research and weaken the quality of your academic writing.

II.  Development and Organization

Before you can begin to determine what the composition of a particular paragraph will be, you must consider what is the most important idea that you are trying to convey to your reader. This is the "controlling idea," or the thesis statement from which you compose the remainder of the paragraph. In other words, your paragraphs should remind your reader that there is a recurrent relationship between your controlling idea and the information in each paragraph. The research problem functions like a seed from which your paper, and your ideas, will grow. The whole process of paragraph development is an organic one—a natural progression from a seed idea to a full-blown research study where there are direct, familial relationships in the paper between all of  your controlling ideas and the paragraphs which derive from them. The decision about what to put into your paragraphs begins with brainstorming about how you want to pursue the research problem . There are many techniques for brainstorming but, whichever one you choose, this stage of paragraph development cannot be skipped because it lays a foundation for developing a set of paragraphs [representing a section of your paper] that describes a specific element of your overall analysis. Each section is described further in this writing guide. Given these factors, every paragraph in a paper should be :

• Unified —All of the sentences in a single paragraph should be related to a single controlling idea [often expressed in the topic sentence of the paragraph].
• Clearly related to the research problem —The sentences should all refer to the central idea, or the thesis, of the paper.
• Coherent —The sentences should be arranged in a logical manner and should follow a definite plan for development.
• Well-developed —Every idea discussed in the paragraph should be adequately explained and supported through evidence and details that work together to explain the paragraph's controlling idea.

There are many different ways you can organize a paragraph . However, the organization you choose will depend on the controlling idea of the paragraph. Ways to organize a paragraph in academic writing include:

• Narrative : Tell a story. Go chronologically, from start to finish.
• Descriptive : Provide specific details about what something looks or feels like. Organize spatially, in order of appearance, or by topic.
• Process : Explain step by step how something works. Perhaps follow a sequence—first, second, third.
• Classification : Separate into groups or explain the various parts of a topic.
• Illustrative : Give examples and explain how those examples prove your point.

Writing Tip

Coherence of Ideas is What Matters, Not Length!

Do not think of developing paragraphs in terms of their length. Length and appearance do not determine whether a part in your paper is a paragraph. It is the unity and coherence of ideas represented in a sentence or among sentences that constitutes to a good paragraph.

How Long Should a Research Paper Be? Data from 61,519 Examples

I analyzed a random sample of 61,519 full-text research papers, uploaded to PubMed Central between the years 2016 and 2021, in order to answer the questions:

What is the typical overall length of a research paper? and how long should each section be?

I used the BioC API to download the data (see the References section below).

Here’s a summary of the key findings

1- The median length of a research paper is 4,133 words (equivalent to 166 sentences or 34 paragraphs), excluding the abstract and references, with 90% of papers being between 2,023 and 8,284 words.

2- A typical article is divided in the following way:

• Introduction section: 14.6% of the total word count.
• Methods section: 29.7% of the total word count.
• Results section: 26.2% of the total word count.
• Discussion section: 29.4% of the total word count.

Notice that the Materials and methods is the longest section of a professionally written article. So always write this section in enough depth to provide the readers with the necessary details that allow them to replicate your study if they wanted to without requiring further information.

Overall length of a research paper

Let’s start by looking at the maximum word count allowed in some of the well-known journals. Note that the numbers reported in this table include the Abstract , Figure legends and References unless otherwise specified:

[1] excluding figure legends [2] excluding references

⚠ Note A review paper is either a systematic review or a meta-analysis, and an original research paper refers to either an observational or an experimental study conducted by the authors themselves.

Notice the large variability between these journals: The maximum number of words allowed ranges between 3,000 and 9,000 words.

Next, let’s look at our data.

Here’s a table that describes the length of a research paper in our sample:

90% of research papers have a word count between 2,023 and 8,284. So it will be a little weird to see a word count outside of this range.

Our data also agree that a typical review paper is a little bit longer than a typical original research paper but not by much (3,858 vs 3,708 words).

Length of each section in a research article

The median article with an IMRaD structure (i.e. contains the following sections: Introduction , Methods , Results and Discussion ) is in general characterized by a short 553 words introduction. And the methods, results and discussion sections are about twice the size of the introduction:

How to Write a Research Paper: Parts of the Paper

• Parts of the Paper
• Writing Tips from UNC-Chapel Hill

Parts of the Research Paper Papers should have a beginning, a middle, and an end. Your introductory paragraph should grab the reader's attention, state your main idea, and indicate how you will support it. The body of the paper should expand on what you have stated in the introduction. Finally, the conclusion restates the paper's thesis and should explain what you have learned, giving a wrap up of your main ideas.

1. The Title The title should be specific and indicate the theme of the research and what ideas it addresses. Use keywords that help explain your paper's topic to the reader. Try to avoid abbreviations and jargon. Think about keywords that people would use to search for your paper and include them in your title.

2. The Abstract The abstract is used by readers to get a quick overview of your paper. Typically, they are about 200 words in length (120 words minimum to  250 words maximum). The abstract should introduce the topic and thesis, and should provide a general statement about what you have found in your research. The abstract allows you to mention each major aspect of your topic and helps readers decide whether they want to read the rest of the paper. Because it is a summary of the entire research paper, it is often written last. 

3. The Introduction The introduction should be designed to attract the reader's attention and explain the focus of the research. You will introduce your overview of the topic,  your main points of information, and why this subject is important. You can introduce the current understanding and background information about the topic. Toward the end of the introduction, you add your thesis statement, and explain how you will provide information to support your research questions. This provides the purpose and focus for the rest of the paper.

4. Thesis Statement Most papers will have a thesis statement or main idea and supporting facts/ideas/arguments. State your main idea (something of interest or something to be proven or argued for or against) as your thesis statement, and then provide your supporting facts and arguments. A thesis statement is a declarative sentence that asserts the position a paper will be taking. It also points toward the paper's development. This statement should be both specific and arguable. Generally, the thesis statement will be placed at the end of the first paragraph of your paper. The remainder of your paper will support this thesis.

Students often learn to write a thesis as a first step in the writing process, but often, after research, a writer's viewpoint may change. Therefore a thesis statement may be one of the final steps in writing.

5. The Literature Review The purpose of the literature review is to describe past important research and how it specifically relates to the research thesis. It should be a synthesis of the previous literature and the new idea being researched. The review should examine the major theories related to the topic to date and their contributors. It should include all relevant findings from credible sources, such as academic books and peer-reviewed journal articles. You will want  to:

• Explain how the literature helps the researcher understand the topic.
• Try to show connections and any disparities between the literature.
• Identify new ways to interpret prior research.
• Reveal any gaps that exist in the literature.

More about writing a literature review. . .

6. The Discussion ​The purpose of the discussion is to interpret and describe what you have learned from your research. Make the reader understand why your topic is important. The discussion should always demonstrate what you have learned from your readings (and viewings) and how that learning has made the topic evolve, especially from the short description of main points in the introduction.Explain any new understanding or insights you have had after reading your articles and/or books. Paragraphs should use transitioning sentences to develop how one paragraph idea leads to the next. The discussion will always connect to the introduction, your thesis statement, and the literature you reviewed, but it does not simply repeat or rearrange the introduction. You want to: 

• Demonstrate critical thinking, not just reporting back facts that you gathered.
• If possible, tell how the topic has evolved over the past and give it's implications for the future.
• Fully explain your main ideas with supporting information.
• Explain why your thesis is correct giving arguments to counter points.

7. The Conclusion A concluding paragraph is a brief summary of your main ideas and restates the paper's main thesis, giving the reader the sense that the stated goal of the paper has been accomplished. What have you learned by doing this research that you didn't know before? What conclusions have you drawn? You may also want to suggest further areas of study, improvement of research possibilities, etc. to demonstrate your critical thinking regarding your research.

How Many Paragraphs in an Essay, Research Paper or in Pages

• by Joseph Kenas
• January 18, 2024

For many students, deciding the number of paragraphs to be included in their research papers can be a big challenge.

Various factors determine the number of paragraphs in a research paper as we shall discuss later in this article. However, before exploring that, it is important to have an informed estimate on the number of paragraphs that should be contained in a research paper. 

How Many Paragraphs in an Essay or Research Paper?

As aforementioned, various factors can determine the number of paragraphs in a research paper. However, to have an informed estimate, we have to consider the structure of a typical research paper. 

The number of paragraphs in an essay or paper depends on its length in terms of pages. For instance, there should be 3 paragraphs in a 1-page essay or 5 paragraphs for a 2-page one. This includes an introduction paragraph, body paragraphs, and a conclusion.

Essays longer than that have more paragraphs depending on the length and the instructions from your faculty.

Longer research papers have many paragraphs compared to short essays. A typical research paper contains an introduction, literature review section, methodology section, findings and discussions section, and finally the conclusion.

For college or undergraduate research papers, your introduction and the conclusion should be made of a single paragraph each. Therefore, the introduction and the conclusion will account for 2 paragraphs in your research paper.

Now, the literature review should  review  credible and recent sources that relate to your research topic.

You are required to identify at least 3 sources and review them within the literature review section while making sure that you relate them to your research topic.

Therefore, if we assume that the review of each source will take 1 paragraph, then you are supposed to have a minimum of 3 paragraphs within the literature review.

When it comes to the methodology section, you are supposed to present the different strategies you will use to gather your research data.

Methods of data collection include but are not limited to experiments, interviews, sampling, questionnaires, observation, and so on. Here, you should be clear and succinct concerning the methods of data collection so that the reader can understand.

Furthermore, you should provide the population of the study, the variables of the methodologies, and other important research information.

You should also connect the methodologies to the research hypothesis or main claim. As such, the methodology section will take about 2 paragraphs for a college-level research paper.

The findings and discussion section should contain more paragraphs compared to the rest of the sections. This is because you are discussing the findings of your research and relating them to your topic and original claims. This section should not be less than 4 paragraphs in length.

Therefore, if we add the 2 paragraphs for the introduction and the conclusion, 3 paragraphs for the literature review, 2 paragraphs for the methodology, and 4 paragraphs for the findings and discussions, you will have a total of 11 paragraphs.

Depending on the content you will be writing, a research paper will have between 10 and 12 paragraphs. 

You should note that this is for a short research paper. A research paper may be more than 20 pages and therefore the number of paragraphs will increase.

However, the basic structure of a research paper should act as a guideline. The number of paragraphs provided above is a minimum. 

Factors Determining the Number of Paragraphs in a Paper

1. professor’s instructions.

The professor’s instructions are key in determining the number of paragraphs in a research paper. They may be very specific in terms of their number due to the research paper structure they give you.

They may provide the basic or typical essay structure and specify the number of paragraphs required for each section. 

2. The Length of the Paper

This is an obvious determinant of the number of paragraphs in a research paper. If the research paper tackles a complex topic, it will be longer.

Check out our word to pages converter tool that can help you know the number of pages so that you can monitor the length of your paper.

A longer research paper will have more paragraphs while shorter research papers will have fewer paragraphs.

If your professor or instructor requires you to submit a long research paper, let’s say 15 pages and more, the paper will have more paragraphs.  

3. The Size of the Paragraphs

The size of the paragraph is also a determinant of the number of paragraphs in a research paper. It should be noted that body paragraphs contain individual claims that are supported with evidence within a single paragraph.

If you have a claim that needs further elaboration and more supporting evidence, you may be forced to write a longer paragraph that may consume more space within a page.

Therefore, if the size of your paragraphs is larger, your research paper will contain fewer paragraphs because they are consuming more space within the paper.

However, if the size of the paragraphs is smaller, then there will be more paragraphs in your search paper. 

4. Personal Preference

At times, your professor may give you the freedom to come up with your research paper. This will include the number of pages, the structure, the number of paragraphs, and even the topic.

In this case, you will craft your research paper based on your preference. You may decide to include more paragraphs that contain more claims to support your argument or even fewer paragraphs.

You may decide to write larger or smaller paragraphs depending on the content you are including in your paragraphs. In the end, you may have more or fewer paragraphs. 

5. Formatting Style

As aforementioned, there is a basic or typical formatting style for college-level research papers. When following such a formatting style, then a research paper will have a minimum of 12 paragraphs.

However, some research paper formats will require you to include more paragraphs in the form of the abstract.

Background of study that comes after the introduction, data analysis that comes after the research methodology, and limitations plus the future scope of your research.

This will add more paragraphs to your research paper. 

6. Number of Graphics in the Essay

Some research papers will require you to represent your data in a graphical format so that your readers can easily understand the data. Good research papers should contain a few graphics.

You should remember that graphics are not part of the text hence they are not part of a paragraph. Be mindful that everything counts. Even spaces do count as characters when you are writing an essay or a paper.

Though this is the case, they still occupy some space within the research paper. As such, the more the graphics in the paper, the lesser the paragraphs, and vice versa. 

FAQs on Paragraphs in an Essay

How many paragraphs are in an essay.

To respond to this question, it should be noted that an essay is less complex compared to a research paper because it tackles simpler topics and doesn’t require too much research. An essay does not need to be divided into sections like in research papers. As such, they have fewer paragraphs compared to research papers. 

Typically, an essay will contain 1 paragraph for the introduction, 3 paragraphs for the body, and 1 paragraph for the conclusion, making the total number of paragraphs to be 5. However, depending on the topic, the number of body paragraphs may increase. 

How many sentences are in a paragraph?

A paragraph should have between 4 and 6 complete sentences. However, the number of sentences in a paragraph is determined by the length of an individual sentence within the paragraph. The longer it is, the fewer the sentences will be, and vice versa. 

How many paragraphs are 10 pages double-spaced?

When calculating this, it is assumed that a double-spaced page should contain 3 paragraphs. Therefore, if there are 10 pages, there will be a total of 30 paragraphs in the paper. 

How many sentences is a paragraph in college?

A college-level paragraph should contain adequate details to support individual claims. As such, it should contain more, well-constructed sentences. When this is considered, such a paragraph should have a minimum of 5 sentences to adequately discuss and support a claim.

How to Structure an Essay

Essay writing is a fundamental skill, a basic task, that is expected of those who choose to pursue their undergraduate and master’s degrees. It constitutes a key requirement for students to complete a given course credit. However, many students and early career researchers find themselves struggling with the challenge of organizing their thoughts into a coherent, engaging structure. This article is especially for those who see essay writing as a daunting task and face problems in presenting their work in an impactful way.

• Problem-methods-solutions structure 
• Compare and contrast structures 
• Frequently asked questions on essay structure 

Read on as we delve into the basic elements of essay writing, outline key principles for organizing information, and cover some foundational features of writing essays.  

Writing an essay: basic elements and some key principles

Essays are written in a flowing and continuous pattern but with a structure of its own. An introduction, body and conclusion are integral to it. The key is to balance the amount and kind of information to be presented in each part. Various disciplines may have their own conventions or guidelines on the information to be provided in the introduction.  

A clear articulation of the context and background of the study is important, as is the definition of key terms and an outline of specific models or theories used. Readers also need to know the significance of the study and its implications for further research. Most importantly, the thesis or the main proposition should be clearly presented.  

The body of the essay is therefore organized into paragraphs that hold the main ideas and arguments and is presented and analyzed in a logical manner. Ideally, each paragraph of the body focuses on one main point or a distinct topic and must be supported by evidence and analysis. The concluding paragraph should bring back to the reader the key arguments, its significance and food for thought. It is best not to re-state all the points of the essay or introduce a new concept here. 

In other words, certain general guidelines help structure the information in the essay. The information must flow logically with the context or the background information presented in the introductory part of the essay. The arguments are built organically where each paragraph in the body of the essay deals with a different point, yet closely linked to the para preceding and following it. Importantly, when writing essays, early career researchers must be careful in ensuring that each piece of information relates to the main thesis and is a building block to the arguments. 

Essay structure template

• Introduction 
• Provide the context and share significance of the study 
• Clearly articulate the thesis statement 
• Body  
• Paragraph 1 consisting of the first main point, followed by supporting evidence and an analysis of the findings. Transitional words and phrases can be used to move to the next main point. 
• There can be as many paragraphs with the above-mentioned elements as there are points and arguments to support your thesis. 
• Conclusion  
• Bring in key ideas and discuss their significance and relevance 
• Call for action 
• References 

Essay structures

The structure of an essay can be determined by the kind of essay that is required.  

Chronological structure

Also known as the cause-and-effect approach, this is a straightforward way to structure an essay. In such essays, events are discussed sequentially, as they occurred from the earliest to the latest. A chronological structure is useful for discussing a series of events or processes such as historical analyses or narratives of events. The introduction should have the topic sentence. The body of the essay should follow a chorological progression with each para discussing a major aspect of that event with supporting evidence. It ends with a summarizing of the results of the events.  

Problem-methods-solutions structure

Where the essay focuses on a specific problem, the problem-methods-solutions structure can be used to organize the essay. This structure is ideal for essays that address complex issues. It starts with presenting the problem, the context, and thesis statement as introduction to the essay. The major part of the discussion which forms the body of the essay focuses on stating the problem and its significance, the author’s approach or methods adopted to address the problem along with its relevance, and accordingly proposing solution(s) to the identified problem. The concluding part offers a recap of the research problem, methods, and proposed solutions, emphasizing their significance and potential impact. 

Compare and contrast structures

This structure of essay writing is ideally used when two or more key subjects require a comparison of ideas, theories, or phenomena. The three crucial elements, introduction, body, and conclusion, remain the same. The introduction presents the context and the thesis statement. The body of the essay seeks to focus on and highlight differences between the subjects, supported by evidence and analysis. The conclusion is used to summarize the key points of comparison and contrast, offering insights into the significance of the analysis.  

Depending on how the subjects will be discussed, the body of the essay can be organized according to the block method or the alternating method. In the block method, one para discusses one subject and the next para the other subject. In the alternative method, both subjects are discussed in one para based on a particular topic or issue followed by the next para on another issue and so on.  

Frequently asked questions on essay structure

An essay structure serves as a framework for presenting ideas coherently and logically. It comprises three crucial elements: an introduction that communicates the context, topic, and thesis statement; the body focusing on the main points and arguments supported with appropriate evidence followed by its analysis; and a conclusion that ties together the main points and its importance .  

An essay structure well-defined essay structure enhances clarity, coherence, and readability, and is crucial for organizing ideas and arguments to effectively communicate key aspects of a chosen topic. It allows readers to better understand arguments presented and demonstrates the author’s ability to organize and present information systematically. 

Yes, while expert recommend following an essay structure, early career researchers may choose how best to adapt standard essay structures to communicate and share their research in an impactful and engaging way. However, do keep in mind that deviating too far from established structures can hinder comprehension and weaken the overall effectiveness of the essay,  By understanding the basic elements of essay writing and employing appropriate structures such as chronological, problem-methods-solutions, or compare and contrast, researchers can effectively organize their ideas and communicate their findings with clarity and precision.

So you need to write an essay. You’ve picked out your topic, determined your thesis, and now you’re ready to put pen to paper (or fingertips to keyboard) to start writing your epic piece. Before you get rolling, there’s only one thing left to decide: how many paragraphs does this essay actually need?

Unless you’re working under a strict assignment, essays can come in all shapes and sizes. Choosing the right format can help you present your ideas in the clearest way possible and make your writing process even easier. Here are the most common formats to consider and what to know before you decide which one to choose.

How many paragraphs are in an essay?

There’s no hard and fast rule for deciding how many paragraphs an essay should have, but it’s important to know that a single paragraph is generally not considered an essay. Standard essays have a designated introduction and conclusion, along with supporting details. This means that even a short essay will still have about three paragraphs, and many have more.

Things to consider before you write an essay

Before you can decide how to divide the information, you need to consider a few things:

• What type of essay are you writing?
• How many supporting details do you need to share?
• Do you have enough information to write a three- to five-sentence paragraph for each supporting detail?
• Do you have a required word count?
• What will be the clearest format for the reader?

There are a lot of different kinds of essays you might be assigned. Generally, multi-paragraph essays are used to compare and contrast things, in persuasive writing, as a form of narrative writing, and for informative or researched essays. Most of these essays end up fitting nicely into one of two main categories:

The five-paragraph essay

Arguably the most common essay format is the standard five-paragraph essay. This essay devotes a paragraph each to the introduction, conclusion, and three different supporting details. Let’s break down what each of those sections includes.

Parts of a standard five-paragraph essay

1. Introduction

This part of the essay includes your thesis statement , introduces your reader to your topic or point of view, and lays out the main ideas of your following three body paragraphs. Generally, this paragraph is brief and intended to grab your reader’s attention.

2. Body paragraphs

A five-paragraph essay includes three body paragraphs. Each of these paragraphs should focus on one supporting detail that aligns with your thesis. They will begin with a topic sentence and share the relevant research, quotes, and anecdotes you’ve gathered.

3. Conclusion

The conclusion to a five-paragraph essay will restate your thesis, sum up your supporting details, and present the reader with one final takeaway from reading your piece.

Wondering what goes into nailing each of these categories? Here’s a sample five-paragraph essay outline and some examples to help you get started.

Which kinds of essays work best with five paragraphs?

Five-paragraph essays are best used to convey complex and detailed topics that require extra information, like:

Comparison essays

A five-paragraph essay allows you to devote one paragraph to each item you’re comparing, as well as include one paragraph on the similarities between the two things.

Argumentative essays

In the five-paragraph format, there is ample space to explore multiple sides of an argument and include plenty of supporting facts and research.

Informative essays

Complex topics are broken down in simple and intuitive ways when the information is spread across multiple paragraphs.

Best practices for writing a five-paragraph essay

If you’re considering a five-paragraph format for your essay, remember:

• These essays must have a clear thesis and conclusion.
• Each body paragraph should contain a strong and complete supporting detail.
• Transition words are necessary to help the flow of the essay.
• These essays usually involve research.
• This is among the most organized ways to present complex topics.

The three-paragraph essay

Three-paragraph essays are shorter and more simplified than the standard five-paragraph essay. Typically, these essays include a conclusion, introduction, and only one body paragraph. This single body paragraph might focus on one supporting detail or it may include a comprehensive summary of a lot of supporting information.

Parts of a standard three-paragraph essay

The introduction to a three-paragraph essay typically includes a hook or attention-grabbing first sentence , followed by a summary of your supporting details and then your thesis. The thesis statement helps lead into the rest of your essay.

Refresh your memory on the different types of thesis statements to get your essay started!

2. Body paragraph

This is the one and only body paragraph in a three-paragraph essay, so it needs to be clear, concise, and as detailed as possible within the space constraints. The body paragraph should include a topic sentence, as well as any details or facts that underscore your thesis. It may focus on one element of your supporting argument or sum up several in brief, clear sentences that relate to the topic sentence.

3. Conclusion 

Much like in a five-paragraph essay, your conclusion is the place to restate your thesis, summarize the points you made in the body paragraph, and leave your reader with a final takeaway or call to action.

Which kinds of essays work best with three paragraphs?

For less complex topics, the three-paragraph essay provides enough space to thoughtfully explain a topic and provide additional information.

Narrative essays

Personal essays that don’t necessarily need multiple paragraphs of supporting information work well in this format.

For emerging writers, one body paragraph provides ample space to compare and contrast two items or ideas. Single sentences can be devoted to each comparison or similarity.

Best practices for writing a three-paragraph essay

If you’re considering a three-paragraph format for your essay, remember:

• Even short essays still need a clear thesis.
• Organize your body paragraph so your ideas are presented clearly.
• The introduction and conclusion should each be a separate paragraph.
• This format provides excellent practice for new writers.
• One body paragraph still leaves room for strong supporting information.

Avoid confusing sentences and write with clarity with these tips.

Breaking Down Essays: How Many Paragraphs Should You Have?

Writing an essay and figuring out the basic structure of an essay is one of the biggest challenges faced by students. But have no fear! Today we’re here to tackle one particularly tricky aspect of writing essays: how many paragraphs should be included?

We’ll look at some rules and guidelines for determining when it’s time to move on to a new paragraph – so you can easily craft your next great essay with confidence.

In this article, I’ll take you through the process step-by-step, offering up examples and strategies that will help readers understand what they need to know in order to write dynamic, engaging essays.

Perfect for anyone looking for ways to break free from tired formulae and express their story ideas in innovative ways.

What Is An Essay?

Essays are a common form of writing used in education and work. They can range from persuasive to argumentative, but all require an organized structure with clear thesis statement , topic sentences and supporting evidence. Writing an essay is like creating a piece of art: you have to know the rules before you break them.

When it comes to understanding the basic structure of an essay, there are typically three primary elements: introduction, body paragraphs and conclusion.

The introduction should provide readers with background information about the subject matter or arguments that will be discussed throughout the essay. It also lays out your main point (thesis statement) for readers so they have an understanding of what is coming next.

Body paragraphs usually follow the introduction, as this is where writers present their arguments and support their points with evidence. Each paragraph serves its own purpose; each one introducing one idea at a time until the writer has made his/her case through multiple topics. To make sure this happens effectively, each paragraph must start with a strong focus sentence (topic sentence) which introduces what that particular section will discuss further on.

From here, we move on to crafting our conclusion – wrapping up all ideas presented within our body paragraphs while reiterating our initial thesis statement and providing some final thoughts on the overall subject matter at hand.

This part should not simply repeat what was previously said but rather tie everything together into something meaningful for readers to take away from our essay’s message.

Understanding The Basic Structure Of An Essay

Ah, the art of essay writing. It’s a crafty exercise that can induce feelings of dread and extreme boredom in many high schoolers—not to mention college students. But, like all arts, it has its place in education and there are various ways to create an effective piece of work.

To understand how to write an essay effectively, you must first learn about its basic structure: paragraphs. Paragraphs are essential components of essays; they provide organization for your thoughts and ideas and should be used throughout the entire paper. Generally speaking, each paragraph should contain one main idea which is then supplemented by evidence from outside sources or personal examples. The length of these paragraphs will vary depending on whether you’re writing a short article or longer research paper, but typically five to six sentences work best for most formats.

To get started on drafting your masterpiece, decide what type of essay you’re going to write (persuasive argumentative etc.) and determine the recommended number of paragraphs per format.

After this step is complete, start brainstorming topics related to the essay prompt and begin jotting down notes as well as any relevant quotes or data points that could support your arguments further down the line.

Once these tasks are accomplished, it’s time to dive into actually constructing those individual paragraphs!

Types Of Essays And Recommended Paragraph Structure

When it comes to essays, there are a variety of types and structures. The number of paragraphs can vary depending on the type of essay being written.

The most common format is the five-paragraph essay:

• an introduction,
• three body paragraphs, and
• a conclusion.

Each paragraph should have around six sentences that are focused on one main idea or point. An argumentative or persuasive essay usually follows this structure as well, but may contain more than five paragraphs if necessary for evidence support.

A cause-and-effect essay typically has two parts;

• an introduction followed by
• either two or four body paragraphs

in which causes and effects are discussed respectively. A research paper contains the same elements as other essays but also includes citations from sources used to back up claims made throughout the document. Personal essays often don’t conform to any specific structure because they focus on feelings rather than facts; however, some writers prefer organizing them into three sections with three separate points per section.

No matter what type of essay you’re writing, it’s important to recognize how many paragraphs each requires so your work meets expectations and flows properly between ideas!

Factors Influencing The Number Of Paragraphs In An Essay

As the old adage goes, “form follows function.”

The same is true for essays: how many paragraphs an essay contains depends on its purpose and complexity of the topic.

When writing an essay, it’s important to consider the length of the assignment, time available to complete the task, and resources at hand.

An essay typically consists of three parts: introduction, body containing three body paragraphs, and conclusion.

Depending on the length of the essay and other factors such as difficulty level or argumentative depth, one may need more than three body paragraphs to fully explain their stance on a given subject matter.

The introduction should include information that draws readers in while also setting up what will be discussed in main points throughout your essay.

After this comes your three body paragraphs where you can expand upon each point made by providing evidence or examples from reliable sources.

Finally, conclude with a clear summary of all key topics that have been addressed in your paper without introducing any new ideas not previously mentioned.

When editing and proofreading your work after completion, look out for ways to improve paragraphing based on readability considerations; ensure your paragraph transitions are logical so readers can follow along easily; check if there is enough text within each body paragraph relative to other sections; identify redundancies or irrelevant information that could be eliminated; and finally re-read sentences to make sure they align with the thesis statement set forth in the introduction section.

With these tips in mind, you’ll be well on your way towards crafting impressive essays!

Paragraphing Tips For Editing And Proofreading

When editing and proofreading an essay, it’s important to make sure the paragraphs are properly structured. Many people don’t realize that the number of paragraphs included in an essay can make a huge difference. 

Generally, essays should have between three and seven paragraphs, depending on the length of the essay. For shorter essays, three paragraphs is usually enough, while for longer ones, seven is the maximum.

In addition, each paragraph should be focused on a particular idea or topic and should have a clear beginning, middle, and end.

Proofreading

When proofreading, it’s also important to pay attention to the length of each paragraph. Paragraphs should be long enough to contain a full thought or idea, but not so long that they become hard to follow.

As a rule of thumb, each paragraph should be around five sentences. If a paragraph is too short, it might not contain enough information. If it’s too long, the point of the paragraph might get lost. It’s also important to make sure that each paragraph logically flows into the next, so the reader can understand the essay’s overall argument. 

Having someone else read over your work can be useful because they might spot something you didn’t notice before-but remember to take their advice on board if it’s valid!

In conclusion, the number of paragraphs in an essay can vary depending on its purpose and type.

However, it’s important to ensure that each paragraph is cohesive and serves a clear purpose within your overall argument.

To make sure each paragraph flows naturally into the next, I recommend editing and proofreading for any errors or awkward phrasing.

Writing a Research Paper Introduction | Step-by-Step Guide

Published on September 24, 2022 by Jack Caulfield . Revised on March 27, 2023.

The introduction to a research paper is where you set up your topic and approach for the reader. It has several key goals:

• Present your topic and get the reader interested
• Provide background or summarize existing research
• Position your own approach
• Detail your specific research problem and problem statement
• Give an overview of the paper’s structure

The introduction looks slightly different depending on whether your paper presents the results of original empirical research or constructs an argument by engaging with a variety of sources.

Step 1: introduce your topic, step 2: describe the background, step 3: establish your research problem, step 4: specify your objective(s), step 5: map out your paper, research paper introduction examples, frequently asked questions about the research paper introduction.

The first job of the introduction is to tell the reader what your topic is and why it’s interesting or important. This is generally accomplished with a strong opening hook.

The hook is a striking opening sentence that clearly conveys the relevance of your topic. Think of an interesting fact or statistic, a strong statement, a question, or a brief anecdote that will get the reader wondering about your topic.

For example, the following could be an effective hook for an argumentative paper about the environmental impact of cattle farming:

A more empirical paper investigating the relationship of Instagram use with body image issues in adolescent girls might use the following hook:

Don’t feel that your hook necessarily has to be deeply impressive or creative. Clarity and relevance are still more important than catchiness. The key thing is to guide the reader into your topic and situate your ideas.

This part of the introduction differs depending on what approach your paper is taking.

In a more argumentative paper, you’ll explore some general background here. In a more empirical paper, this is the place to review previous research and establish how yours fits in.

Argumentative paper: Background information

After you’ve caught your reader’s attention, specify a bit more, providing context and narrowing down your topic.

Provide only the most relevant background information. The introduction isn’t the place to get too in-depth; if more background is essential to your paper, it can appear in the body .

Empirical paper: Describing previous research

For a paper describing original research, you’ll instead provide an overview of the most relevant research that has already been conducted. This is a sort of miniature literature review —a sketch of the current state of research into your topic, boiled down to a few sentences.

This should be informed by genuine engagement with the literature. Your search can be less extensive than in a full literature review, but a clear sense of the relevant research is crucial to inform your own work.

Begin by establishing the kinds of research that have been done, and end with limitations or gaps in the research that you intend to respond to.

The next step is to clarify how your own research fits in and what problem it addresses.

Argumentative paper: Emphasize importance

In an argumentative research paper, you can simply state the problem you intend to discuss, and what is original or important about your argument.

Empirical paper: Relate to the literature

In an empirical research paper, try to lead into the problem on the basis of your discussion of the literature. Think in terms of these questions:

• What research gap is your work intended to fill?
• What limitations in previous work does it address?
• What contribution to knowledge does it make?

You can make the connection between your problem and the existing research using phrases like the following.

Now you’ll get into the specifics of what you intend to find out or express in your research paper.

The way you frame your research objectives varies. An argumentative paper presents a thesis statement, while an empirical paper generally poses a research question (sometimes with a hypothesis as to the answer).

Argumentative paper: Thesis statement

The thesis statement expresses the position that the rest of the paper will present evidence and arguments for. It can be presented in one or two sentences, and should state your position clearly and directly, without providing specific arguments for it at this point.

Empirical paper: Research question and hypothesis

The research question is the question you want to answer in an empirical research paper.

Present your research question clearly and directly, with a minimum of discussion at this point. The rest of the paper will be taken up with discussing and investigating this question; here you just need to express it.

A research question can be framed either directly or indirectly.

• This study set out to answer the following question: What effects does daily use of Instagram have on the prevalence of body image issues among adolescent girls?
• We investigated the effects of daily Instagram use on the prevalence of body image issues among adolescent girls.

If your research involved testing hypotheses , these should be stated along with your research question. They are usually presented in the past tense, since the hypothesis will already have been tested by the time you are writing up your paper.

For example, the following hypothesis might respond to the research question above:

Prevent plagiarism. Run a free check.

The final part of the introduction is often dedicated to a brief overview of the rest of the paper.

In a paper structured using the standard scientific “introduction, methods, results, discussion” format, this isn’t always necessary. But if your paper is structured in a less predictable way, it’s important to describe the shape of it for the reader.

If included, the overview should be concise, direct, and written in the present tense.

• This paper will first discuss several examples of survey-based research into adolescent social media use, then will go on to …
• This paper first discusses several examples of survey-based research into adolescent social media use, then goes on to …

Full examples of research paper introductions are shown in the tabs below: one for an argumentative paper, the other for an empirical paper.

• Empirical paper

Are cows responsible for climate change? A recent study (RIVM, 2019) shows that cattle farmers account for two thirds of agricultural nitrogen emissions in the Netherlands. These emissions result from nitrogen in manure, which can degrade into ammonia and enter the atmosphere. The study’s calculations show that agriculture is the main source of nitrogen pollution, accounting for 46% of the country’s total emissions. By comparison, road traffic and households are responsible for 6.1% each, the industrial sector for 1%. While efforts are being made to mitigate these emissions, policymakers are reluctant to reckon with the scale of the problem. The approach presented here is a radical one, but commensurate with the issue. This paper argues that the Dutch government must stimulate and subsidize livestock farmers, especially cattle farmers, to transition to sustainable vegetable farming. It first establishes the inadequacy of current mitigation measures, then discusses the various advantages of the results proposed, and finally addresses potential objections to the plan on economic grounds.

The rise of social media has been accompanied by a sharp increase in the prevalence of body image issues among women and girls. This correlation has received significant academic attention: Various empirical studies have been conducted into Facebook usage among adolescent girls (Tiggermann & Slater, 2013; Meier & Gray, 2014). These studies have consistently found that the visual and interactive aspects of the platform have the greatest influence on body image issues. Despite this, highly visual social media (HVSM) such as Instagram have yet to be robustly researched. This paper sets out to address this research gap. We investigated the effects of daily Instagram use on the prevalence of body image issues among adolescent girls. It was hypothesized that daily Instagram use would be associated with an increase in body image concerns and a decrease in self-esteem ratings.

The introduction of a research paper includes several key elements:

• A hook to catch the reader’s interest
• Relevant background on the topic
• Details of your research problem

and your problem statement

• A thesis statement or research question
• Sometimes an overview of the paper

Don’t feel that you have to write the introduction first. The introduction is often one of the last parts of the research paper you’ll write, along with the conclusion.

This is because it can be easier to introduce your paper once you’ve already written the body ; you may not have the clearest idea of your arguments until you’ve written them, and things can change during the writing process .

The way you present your research problem in your introduction varies depending on the nature of your research paper . A research paper that presents a sustained argument will usually encapsulate this argument in a thesis statement .

A research paper designed to present the results of empirical research tends to present a research question that it seeks to answer. It may also include a hypothesis —a prediction that will be confirmed or disproved by your research.

The Three-Paragraph Introduction: An Alternative to the Research Paper

Three Paragraph Introduction: An alternative to writing a research paper

Mark Giordano

July 10, 2017

One goal of my interdisciplinary (but primarily social and natural science based) freshman proseminar is to develop the skills to identify a research question. A second goal is to help the students master college level writing skills. I have found that meeting these goals through the assignment of a traditional research paper is problematic for two reasons. First, students struggle to understand the difference between identifying a research gap and constructing a paper to fill the gap (e.g. are the environmental impacts of dams always negative?) and constructing a paper to argue a point (e.g. we should build fewer dams), let alone actually do the research. Second, even if formats for structuring a research paper are given, students often struggle with logical flows within and between paragraphs and sections. Third, it is problematic for students to learn from feedback unless they have opportunities to revise their papers at least once and preferably more times. Multiple revision is logistically difficult given the lengths of traditional papers and the nature of the semester.

To meet my class content goals and partly address these issues around writing, I created a shorter, iterative research and writing assignment that focuses primarily on setting up a research paper, rather than writing the whole paper. In essence, the core of the assignment is to write just a three paragraph introduction. While the assignment is backed up with two, 4-5 page “content” papers, they are designed primarily to help students engage with and mentally organize content rather than as writing assignments per se. In terms of writing, my feedback to students, their revisions and my grading are focused primarily on the 3 paragraph introduction.

The steps I follow to implement the assignment are:

• Relatively early in the semester, students are given background and instructions to the assignment, though there is nothing due for multiple weeks. The instructions are along these lines:

“A good introduction to a research paper can be as short as 3 paragraphs. It requires convincing people that your issue is important (paragraph 1), explaining what information gaps exist (paragraph 2), and demonstrating that your paper will at least partially fill one or more of those gaps and perhaps what your research found (paragraph 3). Writing paragraph 1 requires you to understand the context of your research. Writing paragraph 2 requires understanding the literature that has already been published. More explanation and discussion will occur over the course of the semester, but for now note that you will be asked to write and rewrite the paragraphs of your introduction as we move through the semester. Rewriting (again and again) is the key to a good paper.”

Over the early weeks of the semester we examine how the introductions of the academic papers we read in class are structured. Included in these readings are papers I wrote. We discuss how the papers conform or not to our in class discussions of what is needed in a good introduction.

• Student decides on general topic half way through the semester and turn in a paper title. We discuss everyone’s titles to draw out issues and share ideas.
• Students write a one paragraph introduction to their research paper as well as a 4-5 page background paper, with citations, that provides the context for their paragraph. The purpose of the background paper is to ensure that students are delving into the subject matter.
• Professor gives detailed feedback on the paragraph. The professor’s comments on the background paper are focused primarily on subject matter, though more general comments may be given on writing.
• Students write a second 4-5 page paper that examines the published literature on their subject and establishes a question that the literature has yet to answer. The paper must include 15-20 academic citations to ensure that the students have engaged reasonably well with the literature. Based on this background paper, students write the second paragraph of their introduction. Students turn in turn in a revised first paragraph, their new second paragraph, and the new 4-5 page background paper.
• Professor gives detailed feedback on the first two paragraphs of the introduction. More general writing comments are given on the background paper. Substantial comments are often given on the content of the background paper as students struggle to understand what a research question really is and how one establishes such a question.
• After students receive feedback, at least one and often more discussions occur in the following classes on what it means to establish a research question.
• Based on feedback, students rewrite their second paragraph, often after doing substantial new literature review. Students also write a new third paragraph in which they suggest the methods they would use to answer their research question and hypothesize their results. As the students do not actually do the research, this paragraph is more of a fun assignment in which they can use their imagination. Students turn in revisions of their first two paragraphs plus their new third paragraph.
• Professor gives detailed comments on the 3 paragraph introduction.
• As the paper is due before the end of the semester, one or more additional class discussions occur on the overall writing experience.
• In some iterations of the class, students also peer review each others papers.

In using this format over the past 3 years, I have found the following advantages and disadvantages:

• The short format allows me to carefully read every word and sentence and provide detailed comments on what worked for the student, what didn’t, and what should be considered in the future to improve the work.
• The iterative process allows (i.e. forces) students to carefully consider my comments and make changes based on them. I find this a major improvement over the typical process in which I write on the papers and am not sure that the comments are even read. The iterative process also encourages in class discussions on both writing and content.
• I set the assignment up in part to to emphasis the difficult to grasp concept of a research question. I find that focusing on the question through short iterative writing, rather than jumping into an attempt at an answer, helps students grasp the idea. In my experience, the importance of purposefully developing this skill of crafting a research question cannot be underestimated. As an example, many students in my senior seminars and those applying to do honors theses do not know what a research question is. The assignment could of course be changed to emphasis other content areas.
• Because the students spend so much time on each paragraph based on feedback and discussion, and because they have carefully thought through an actual research question, they often use their work from my class in their applications for research-based scholarships and other opportunities. In some cases they use their actual work from my class in their applications. In others, they choose new topics but model their proposals on their 3 paragraph introductions.
• While I do grade each iteration of the assignment, I have found it difficult to develop rubrics to fairly differentiate students and their efforts, especially as the papers improve over the course of the semester.

INSTRUCTIONS FOR THE ASSIGNMENT PROVIDED TO STUDENTS IN THE CLASS SYLLABUS

Research paper introduction and lit review

The main product for the class is the introduction to a research paper and the supporting literature review. YOU DO NOT ACTUALLY DO THE RESEARCH OR WRITE A FULL PAPER. The product will be accomplished through 6 relatively short, interconnected writing assignments. Due dates for each assignment are given in the schedule. The assignments have three main goals beyond learning about water. The first is to help you learn the difference between research and reporting/advocacy/argument. The second is to help you learn how to construct a strong opening for the many papers you will have to write at Georgetown and the rest of your life. The third is to learn how to do a literature review either for a research paper or to establish the evidence base for decision making.

A good introduction to a research paper can be as short as 3 paragraphs. It requires convincing people that your issue is important (paragraph 1), explaining what information gaps are still out there (paragraph 2), and demonstrating that your paper will at least partially fill one or more of those gaps (paragraph 3). Writing paragraph 2 requires understanding the literature that has already been published. More explanation and discussion will occur over the course of the semester, but for now note that you will be asked to write and rewrite the paragraphs of your introduction as we move through the semester. Rewriting (again and again) is the key to a good paper.

The assignment has 4 main goals:

• Learn more indepth information about an aspect of the class that interests you,
• Learning the difference between research and reporting/advocacy/argument.
• Learning how to construct a strong opening for any academic paper
• Learning how to conduct a literature review either for a research paper or to establish the evidence base for decision making.

All assignment must be turned into Canvas.

Part 1: Paper Title (0%) Provide a title for you paper in the form of a question. You can change the title every time you turn in your paper. While you get no points for doing this, you still lose 1% of your total grade for everyday the title is late.

Part 2: Background to the topic (5%) You need to make sure your topic is interesting andrite a paper of approximately 4-5 pages describing what your topic is and why the reader should care about it. You must cite at least 10 works. Citations may come from academic literature, but for this part of the assignment they may also come from popular press.

Part 2 : First paragraph to the introduction (10%) What is the paper about and why is it worth reading? Writing a good introductory paragraph requires an ability to convey an overall understanding of the issues and how they fit into the reader’s world. It establishes whether the reader wants to continue reading your paper and sets the stage for the work you will do. The introductory paragraph may include citations from popular press, academic articles, or both.

Part 5: First two paragraphs of your paper 5%

Part 6: Full introduction including paragraph on how you will fill the gap (3 paragraphs) 5%

All assignments must be emailed to me by 8am on the day they are due. Your file must be named INAF100_LASTNAME_#, where LASTNAME represents your family name and # represents the assignment number

How to do citations in this class

Like this: “Giordano (2015) believe that ….,”

or like this: “Some researchers (Giordano, 2105; Byman, 2016) believe that…”

In your bibliography, for all academic articles, use one of the automatic formats provided by GoogleScholar, e.g.:

Wolf, A. T., Yoffe, S. B., & Giordano, M. (2003). International waters: Identifying basins at risk. Water policy, 5(1), 29-60.

Do not use footnotes or endnotes to cite sources.

If you do not cite as instructed, your assignment is automatically reduced by one letter grade.

Part 4: Justifying the research question/gap (2-4 pages) 15%

Part 3: Revised first paragraph to the introduction, second paragraph to the introduction, and literature review (20%)

A research paper requires an original research question or the establishment of a knowledge gap that needs to be filled. To be credible, you must convince the reader that you are aware of what is already known by doing a literature review and articulating it to the reader. For this class, the literature review must include AT LEAST 20 ACADEMIC articles. Can you include non-academic articles? YES. Do you still need 20 academic articles? YES.

You must organize your literature review using a typology (method for classification) that you create. In other words, don’t discuss the articles one after the other. Instead, organize the ideas in each article according to concepts you define as important. Don’t write, “Johnson (2015) says this. Smith (2013) says that.” Instead write, “The literature on water and conflict is divided into two camps. The first camp (Jones, 2013; Smith, 2015) highlights that increased scarcity will inevitably lead to increased social tensions. The second camp (Wight, 2010; Billinglea, 2012) highlights that increased scarcity induces the creation of new institutions to mitigate scarcity’s impact.” You might then explain specifics of some of the authors, but the organization (typology) is generally by concept, not author.

You must define the concepts (typologies) in the way that makes sense to your project and the academic fields from which you are drawing. For this assignment, the typology should be clearly labeled by creating sub-headings in the literature review section. You must also provide a summary of the literature review at the end of the section that leads the reader to understand what the research question/knowledge gap is that your project (if you were to actually do it) would attempt to address.

This assignment should be structured like this:

Title (edited version of what you already produced for Parts I and II)

Introduction

First Paragraph (edited version of what you already produced for Part II)

Second Paragraph (summarizes for the reader the knowledge gap that you identify in your literature review and that your research would fill if you were to actually do it).

Literature Review

Introductory paragraph/section

Sub-heading 1

Sub-heading 2

Sub-heading 3….

Summary paragraph/section

How long should a literature review be? There is no clear answer, but probably 5 or so pages. A literature review in a journal like Science might be one or two paragraphs. A literature review for a PhD thesis might be one or more chapters.

It is important to note that the literature about your topic does not have to be specifically about your PARTICULAR topic. Good research draws on theory, not just subjects. If you want to write a paper on whether Bangladesh and India are going to fight over the Ganges, you don’t want to only look at the literature on India, Bangladesh and the Ganges. You might also, for example, want to consider the literature on theories of international conflict and then try to apply those to the case of India and Bangladesh and their shared river.

Part 4: Full introduction and literature review (20%)

For the final assignment, turn in a three paragraph introduction and literature review. Format you paper in the style of one of the papers you cite in your literature review.

The assignment should be structured like this:

Title (edited version of what you already produced for Part III)

Abstract (100 words or less)

First paragraph (edited version of what you already produced for Part III)

Second paragraph: edited version of what you already turned in for Part III)

Third paragraph: How your project would fill answer the question/fill the gap and what it concludes (you hypothesize the conclusion)

Literature Review (edited version of what you already produced for part III)

How Long Should a Research Paper be: From Intro to conclusion

research paper length

You may be wondering how long your research paper should be? Well, you are not alone. Many students are always asking about the optimal term paper length. This challenge can be further heightened when your instructor has not provided you with the page limit or word count.

Research papers are quite complex because they are academic writings based on your original research on a specific topic. This is why getting our paper writing help can be useful to get that A.

No matter the method you choose, your paper should contain your analysis and interpretation of the findings to be complete.

When considering all those factors, students often wonder how long their research papers should be. Let’s explore this in detail.

Easy navigation table

How Long Should each part of a Research Paper be

Ideally, the most optimal length of a research paper is around 5 pages for short papers and 10 pages for long ones. However, the exact length of your term paper is best determined by your instructor and his instructions.

The same is determined by a number of factors, including the extent and depth of your subject.

Factors Determining the Length of a Paper

The question of how long a research paper should be can be difficult to respond to because it depends on several factors. The most important factors that determine the length of your term paper include;

• The subject of your research
• The number of topics emerging from the subject,
• Number and complexity of the subtopics,
• The magnitude of your findings
• The extent of your discussions and conclusions.

All those factors held constant; it is possible to estimate the length of a less complex research paper if it is demarcated into sections that include the outline, introduction, individual paragraphs, conclusion, and reference page.

Those are the basic components of a typical research paper . Let’s have a look at how long each section should be.

Let us Write your Papers! No Plagiarism

Get that A on your next essay assignment without the hassles. Any topic or subject. 100% Plagiarism-Free Essays.

How a Term Paper Outline Should be

An outline is an important part of your research paper. It provides the structure of your paper. It organizes the contents of your term paper into sections.

However, the outline does not contain details about your paper. It only highlights the topics to be covered and the issues to be tackled within those topics.

A format of an outline should include the following;

• An Introduction
• The issue that is being tackled
• A literature review
• Methodology
• Results and discussion
• Conclusion and recommendation

There are brief full-sentence descriptions under the five sections that act as guidelines for your research paper. Therefore, the outline should not exceed 2 pages for short research papers and between 4 to 5 pages for longer papers with 15 to 20 pages.

Let us help you get that A in your next assignment. Place your order today, and you will enjoy the benefits.

Optimal Length of a Research Paper Introduction

As we have noted, the length of your term paper depends on the topic and its contents. This applies to the introduction. For a typical 5-page research paper, your introduction should not exceed half a page.

However, if you are writing a long essay of 15 pages or more, the introduction may span to a page or several paragraphs. Since most of the research papers given to undergraduate college students are not lengthy, the introduction should not exceed a page.

Recommended length of Individual paragraphs in research paper

Even though no definitive rules determine the length of individual paragraphs in a paper, the most recommended length is between 90 words and 130 words. Any paragraph below 90 words is deemed too short to sustain an argument, while one with over 130 words is deemed over-argued.

At the same, it is important to note that the length of the paper determines its length. When the paper is short, then the paragraphs should be short.

If the research paper is long, then the paragraphs should be longer. However, a paragraph should contain more than four sentences. For some topics like childhood obesity , the paragraphs may take longer to incorporate data and statistics in your paper.

Since individual paragraphs should focus on one idea, the length of the paragraph should be determined by the supporting text.

If your idea requires a lot of support in the form of illustrations, examples, statistics, paraphrases, quotes, definitions, causes, and effects, then the paragraph will be longer.

In case the idea presented by the individual paragraph is straightforward and does not require a lot of supporting evidence, then it will be shorter.

The paragraphs add content to the outline. The outline provides topics, subtopics, and guidelines, while the paragraphs add content and further explanations.

How Long Should a Conclusion be

A conclusion is a very important part of your research paper. This is because you, as the author of your paper, are wrapping up everything you have discussed in your paper.

Basically, the length of the conclusion is determined by your paper’s length.

The longer the paper, the longer the conclusion, and the shorter it is, the shorter the conclusion. A conclusion should not be below 3 sentences. It will take a few hours to write all these components of your paper.

Even though this is the case, an effective conclusion should have the following characteristics.

Characteristics of a Good Term Paper Conclusion

• Restatement of the topic of your research
• Restatement of your thesis. This statement should not be identical to what you wrote in the introduction.
• Provide a summary of your main points. Do not provide any new information.
• You can also add up the points to further explain the significance of your points.
• Make a call to action if it is appropriate or significant to your paper.
• Respond to the “so what” question. This requires you to explain the context of your paper and why it matters to the readers.

From this, it is evident that the conclusion is very important in your research paper. You may not include all of the above, but it is important to restate your paper’s topic, thesis, and main points. Check our research paper writing guide to learn more about how to write these parts.

How Long should the Reference Page be?

The reference page length completely depends on the number of sources you have used in your paper. Your paper may be lengthy with few sources, while others can be shorter with more.

A good term paper should have a reference page listing all your information sources. Provided that you list the sources in the right referencing format, like APA and MLA , the length of the reference page is not definitive.

Frequently Asked Questions

How long should a term paper be for high school.

Most teachers in high schools require their students to submit 3 to 5-page research papers. Those are the normal research papers assigned within the semester. However, final research papers like the English 102 papers are between 5 and 7 pages.

What is the optimal graduate paper length?

Even though the topic of the graduate paper determines its length, such papers are considerably longer. This is because they tackle complex topics requiring in-depth explanations, citations, examples, etc. They can be between 7 and 15 pages. They can also exceed the count.

How long should a term paper be for middle school?

The research papers written by students in middle school are considerably shorter than those given to college or graduate school students. The normal papers written within the semester are between 1 and 2 pages, while the final papers are between 2 and 4.

How long should a literature review be for a research paper?

The length of a literature review depends on the purpose and the audience of the term paper. In most of the research papers in college, the literature review should not exceed two pages. For longer papers of more than 10 pages, it can be between 2 and 3 pages.

How to write a term paper fast

To write a research paper fast, begin by selecting a topic. This is followed by researching the topic and working on a thesis. Write the structure of your paper by creating an outline.

Follow the outline and write the paper by beginning with an introduction and ending with a conclusion. Finally, proofread your paper to correct errors. Read our checklist on how to revise your paper to a final copy.

What are the most common types of research paper formats

You must select a specific style when formatting a research or term paper. The most common formats for research papers are MLA, APA, Chicago, and Harvard.

Each format dictates the style of the paper, the spacing, the in-text citation style, and the reference page style. You can get all these done if you get someone to write your homework at a very reasonable cost.

What is the average length of an academic journal article

Most academic journal articles span 20 to 25 pages when they have a one-and-half line spacing. If the academic journals are double-spaced, they can be between 25 and 30 pages. The journal’s word count ranges from 4000 to 7000 words.

How Long Should A Research Paper Be?

You must have known what research looks like. It has a particular structure that should be followed at any cost since it is the criteria for  writing a research paper . Several questions come into the mind of students such as how to write a research paper, how long should a research paper be, etc.

That’s why we have brought a series of research writing and addressing different questions related to it. This blog aims to answer queries about the duration your research should ideally take, including insights on how to write an 8-page paper effectively. Although it depends upon the guidelines given by your teacher, there is also a standard length of research writing. Let’s dive in and learn everything about the ideal word count of any research.

What is a Research Paper?

A research paper is an essay that is based on your investigational work you have completed or will complete on just one or many specific topics of a specific discipline. Research or investigation essays are lengthy depending on the scope and extensive nature of the topic.

It’s just an analysis of the topic from your own perspective. A student or a reader present facts and their theories in front of the audience to inform them about the specific subject matter. If you dont know how long is a research paper, here we will take you on a deeper tour to help you understand these essays thoroughly.

What is the Standard Length of a Research Paper?

Discussing the standard length of a paper, it’s important to note that it varies depending on the specific instructions given to each student and the structural requirements related to their chosen finance research topics . It is never a fixed one for all types of papers yet, there are some conditions and possibilities because of which the word count varies.

Research that has a thesis statement only requires 2 to 3 arguments to be proved and will be summed up in 500 to 700 words. After providing the introduction and a little background on the research, you can directly shift to mentioning the arguments and claims so you may prove the statement and complete the research.

Some research requires detailed analysis and interpretation of the findings. This kind of paper has several stages such as introduction, background, thesis statement, objective, research questions, literature review, research methodology, data collection, discussion, findings, conclusion, and bibliography. Such research easily crosses 5000 words because it is important to discuss everything about the topic.

So it entirely depends upon the structure you are following to write the research. It could be as long as just 500 words, or 5000 words, and even more. It all varies therefore you must be prepared for writing a paper no matter how long it should be.

How long is introduction in research paper?

Many students wonder how long should an introduction be in a research paper? The simple answer to this query is as short as possible that justify the requirements and employ all the methods that are necessary for coveying your message.

Typically, a standard length of introductory paragraph is 300-500 words. If your topic needs more than the standard word count than always ask for suggestion from your professor on first priority. We hope now you know how long should an introduction be for a research paper. 

Why Considering Length of a Research Paper is Important

Identifying the length of research is important because of so many reasons. You might have never realized the significance of considering how long a paper should be, so here we go with some of the vital reasons.

1. Going Extra May Ruin Your Research

You cannot write more than is required in research. If you are doing so then you are automatically ignoring the quality measures of writing a paper. If you are writing more than words than is required then there are chances you are going to submit a poor quality research work.

2. Sticking to the Guidelines is Important

When your guidelines have mentioned 1000 words maximum and you are submitting research of 2000 words, you already know what wrong you have done. If you are not sticking to the guidelines it will result in deduction of marks, fall in grades, and repetition of the class course.

3. Having a Balance is Good

It is necessary to keep a balance between the word count of all the headings. Without this much-needed balance, you might end up submitting a poor paper that has a longer introduction, and a shorter explanation of the findings. That’s why attaining a balance is important in your research word count.

4. Delivering Quality Research is the Criteria

When you are delivering quality content, you will be appreciated no matter what. If you consider the length of your research, you are one step forward in delivering quality research work to your teacher.

How Long Should a Research Paper Be?

This question is valid and one of the frequently asked questions by the students of high school and college. It is also important to know before you start working on your paper. Don’t forget to read the instructions provided by your teacher, however, we have more suggestions for you regarding the length of the research.

1. It All Depends On Your Teacher First

Your teacher indeed decides what should be the ideal length of your research. They have given some guidelines to you and you need to follow them. The teachers always know the best and they will suggest to you how long your essay should be.

Some teachers have kept a certain word limit for the paper while others provide you complete freedom to write as long as you want. It is necessary to figure out what’s best for your research. In high schools, a standard length of any research is a maximum of 7 to 8 pages while the minimum should be 5 pages.

2. Check How Much Length is Required to Justify Your Statement

Sometimes it is based on the  thesis for research paper . From the part of the abstract to the conclusion, there must be a balance between the word count of every heading. It is your responsibility as a writer to track the word count when you are trying to justify your thesis by giving several arguments and claims.

If you have decided how many arguments it will take to prove your thesis, then you have already finalized the length of your research. All you have to do is prepare everything in advance and see if you are proving your point within 5 or 8 pages.

3. It Shouldn’t Miss Any Point

A researcher must be discussing all the standard details that could justify the purpose of writing the paper. It must have all the headings properly discussed. Since all the points must be 100% clear in the research, deciding on a word limit in the very beginning could be a little hard.

But it is not impossible to identify by making an outline and checking how many pages will be covered in writing about a certain topic. All you have to do is take care that no point is missing in the research. Cutting the research short and trying to discuss facts to the exact point won’t help unless you are entirely explaining every aspect as required.

How Long a Research Paper Should be in Words?

You have learned something about the ideal length of research. When it comes to the word count, the criterion is a bit different. For example, if you need a  Ph.D. research paper help , you must know the word count, typically between 70,000 to 80,000 words. As you suggest a specific word count for every heading, it is easier to guess how many words are required to summarize every title.

1. Assign Word Count To Each Heading

It is easier to assign a specific word count to every heading and then see what’s the total word length of the paper. For instance, you have to decide how many words will be used to cover your introduction section. A literature review is a second longer part after the discussion in every research so it is necessary to make an outline in advance and see what is the ideal length of every heading.

By giving a suggested word count to each heading you will make a clear pathway to follow during the complete research. It will be automatically easier for you to see how many words will be written to explain everything in your research thoroughly.

There are several sections in research that require certain word counts. Let’s see what word count is usually subjected to every heading.

An  abstract for a research paper  is the first main part that summarizes the research from the beginning to the conclusion. It contains the thesis, methodology, findings, and conclusion. So to explain the complete research in a few sentences, roughly 100 to 200 words will be required. So you may keep in mind the word count for an abstract is a maximum of 200 words.

● Introduction

An introduction is also a major part of the research and it is easily covered within 300 words maximum. Nothing else is required to explain terminologies or theories in this section.  However, there are many opinion on this topic and each have different answers. That’s the prime reason students spend day and night on google looking for answers on their questions such as how long should introduction be for research paper. In short, 300 to 500 words are more than enough to state your thoughts in an into section and persuade your readers.

● Literature Review

The literature review is the second-longest section in any research. It contains a reference to the past research done in a similar field by other researchers. Every research must have 5 to 8 or even more past papers discussed in it. Therefore the ideal word count for this section is 500 to 1000 words.

● Methodology

The methodology section also has subcategories in which you have to explain the method of research, data collection, population, research implications, research Instrument, etc. It will take around 300 to 400 words and 100 words extra if you are discussing a theoretical framework too.

● Discussion and Interpretation

This is the longest part of any research since you have to explain all the findings and tell your readers how successfully you have managed to prove your thesis. This part is as long as 500 to 1000 or even 1500 words depending upon the results and the explanation required.

● Conclusion

A conclusion is a not so lengthy part of the paper. It is usually done within only 100 or 150 words maximum. It is that simple and thus it doesn’t need so many words to finish the argument and put a full stop.

2. Form a Paper Outline

Forming a paper outline in advance will also help you in understanding how many words you may need to cover every heading. This is one of the best ideas for assigning a particular word count to every heading of the paper.

As you’ll create a paper outline, you will get an instant idea of how many words you have to write in total to complete the research. Following this strategy will surely help you won’t be puzzled later during the writing process.

3. Ask Your Instructor

It is always a good idea to ask your teacher or instructor before following any word count technique. They have assigned you a paper so they can provide you with a better guideline to write your paper. It is the easiest method of identifying the word count of your research as it’s something recommended by an expert. Your job will become much easier and simpler by just seeking advice from your teacher.

How Long a Research Paper Should be for Middle School?

A middle school student is just starting with the research work and they are at the initial stages of learning how to conduct research. To understand how long a paper should be for middle school, you need to do some work.

1. Seek Expert Help

It is always better to seek help from an expert to decide the word limit of your essay when you’re a high school student. It could be your teacher or any senior student who will help you and guide how many pages you should write for your research. It is suggested to write 4 to 5 pages when you are a middle school student in writing a paper.

2. Do Research

It is always important to do some research and find out what’s best for your paper. Google is always open to helping students in learning new things without any limit. You can open the Google search engine, write down your query in the search bar and click on it.

Next, you will have everything to read and understand how a paper for middle school will work. By doing so you will automatically get an in-depth idea of crafting research for the initial level project.

After analyzing everything you can easily guess what should be the length of any research written by a middle school student. In pages, it is suggested to write 3 to 5 pages, but in words, it is recommended to write  400 to 500 words only. You can also hire a professional paper writing service to aid you in the process.

As it’s a new thing for the students to perform, they might get nervous easily. That’s why starting slow and taking baby steps towards learning research writing will help a lot.

How long Should a Research Paper be for High School?

High school is a different stage than middle school. You are mature, better at studies, and even more creative than before. This stage comes with its challenges and one of them is writing the research. If you are a new high school student we bet you don’t know much about paper writing at this level.

When a high school student writes a research paper, it’s usually written within 500 to 1000 words. It could be more than this word count or just 5 to 6 pages. The teacher’s instructions do matter a lot in this aspect and without them, you can’t understand the criteria of research writing. It takes a lot of research, consultation, and creativity to write a paper that stands out. The competition is even tougher in high schools so you know how tough it can get to  write a research paper fast .

Your research will decide if you are going to pass the school or not. Many students stay stuck in a class because they are incapable of submitting a brilliant research paper. Most of the time it’s because they don’t know the standard guidelines for writing a paper.

They usually end up ignoring the pattern, writing incorrect information, or exceeding or limiting the length assigned for the research. So it’s better to keep in mind what is the better approach for research writing and how a high school student can learn to write it.

How Long Should a Research Paper be for College?

Have you ever thought about how long your research should be when you have finally reached college? It is the final stage of your education and writing research in this phase will require a lot of preparation. In college, you have to write the longest research papers because it is the standard of a paper written by a college student.

So how exactly long should research be for college? It starts with roughly 3000 words and goes up to 15000 words. 15000 words is a lot but students who are working on their thesis need a lot of details to justify and complete their research. Without doing this they are not getting passed at any cost so now you know why it is so important.

Different sections of the paper require their particular word count. It is sometimes difficult to identify but your teachers will always be there to guide you. Sometimes students are given the entire freedom to keep their essay length on their own. It helps them understand how easily they can prove their thesis either in a few or a lot of pages.

For newcomers in college unsure about the ideal length for research papers, utilizing Google is a great option to delve deeper into the nuances of research writing. It’s particularly helpful in exploring various guidelines related to history research topics . A lot of content is already published on the web which teaches the students almost everything they need.

We hope you know how long is a research paper, no matter if you are writing one for your middle school, high school, or college. All of them have different requirements and basic criteria that should be followed. We also hope this blog has helped you learn everything about deciding the word count or overall length of your research.

What is the average length of a research paper?

The average length of a research paper is usually 5 to 7 pages. It can also be more or less than this but it is the standard length of research

Can I write a research paper in 2 days?

How long does it take to write a 7-page research paper.

A 7-page research paper is quite lengthy and it will require about 3 to 4 days for completion. It involves research, outlining, writing, and proofreading so 4 days are suitable to write a 7-page research paper. Taking 5 days or a week is also justified in writing 7-page research. Most of the teachers give 2 to 3 weeks to complete such a project.

How long is too long for a research paper?

A college research paper exceeding the 5000-word limit is too long if the guidelines have suggested less than 5000 words to write. There is no particular length as such because it is all based on the requirements of research writing.

How many paragraphs should a research paper have?

A research paper is usually not written by counting the paragraphs. It is written headings or pages-wise. Though for a middle school paper it must have 10 to 12 paragraphs, 15 to 18 paragraphs for a high school paper, and more than 20 paragraphs for a college research project.

How long should a research paper be? And how to hit the word count

Emily is a creative content maker and 2021 Innovative Educator Award winner. She effortlessly simplifies complex topics

Research papers cover a broad range of academic pieces, including term papers, case studies, scientific publications, capstone projects, and more. They share similar goals and basic structure, but they vary significantly in length, depending on type, school, class, and topic.

So, how long is a research paper? How long should different sections be? Should you measure the length in words or pages?

In this post, we’ll answer these and many other questions, so keep reading.

How long should a research paper be? Requirements by section

Ideally, you want to address your “How long should a research paper be?” question to your instructor who assigned the task. The word count or page requirements should be present within the prompt. 

Note that research paper requirements can come in words or pages. Generally, one page of double-spaced 12 pt font, which is universal to most formatting styles, is between 250 and 300 words. So, if your professor wants 20 pages, the research papers will include around 5,000 words. That’s a rough average we estimate based on studying common answers to “How long is a research paper?” across top US colleges.

If the numbers seem a bit intimidating and evoke an extreme case of writer’s block, let’s use the age-old trick and split the big task into manageable chunks. We’ll go over all the major research paper sections one at a time and look at how long each of them should be.

Many students fail to account for an abstract when calculating the answer to “How long should a research paper be?”. That’s understandable if you’re dealing with an MLA piece that doesn’t have specific abstract requirements. But in all other cases, it’s a critical consideration.

So, how long should the abstract of a research paper be?

APA requirements for writing an abstract specify it should be no longer than 250 words (one page), including the heading and the list of keywords at the bottom. Most professors share the notion that an abstract should be no longer than one page, though it could be shorter.

Each scientific journal has specific research paper abstract requirements that range from 100 to 300 words, depending on the research paper length and other factors.

Introduction

The short answer to “How long should an introduction be?” is about 5% to 10% of the research paper length. For a 5,000-word project that amounts to between 250 and 500 words (one or two double-spaced 12 pt pages).

A more detailed look at “How long is an introduction?” requires you to have a good idea of the overall research paper outline you plan to use. For example, if you plan to write a research paper introduction that only includes a brief background exploration, a thesis statement, and research objectives, two pages should be more than enough to cover everything. However, if you plan to combine the introduction with the literature review, the first section will be much longer and probably span around 30% of the project. In this case, if your answer for “How long should a research paper be?” is 5,000 words, then your introductory chapter would cover around 1,500 words.

Many students get confused when asking “How long should a thesis statement be for a research paper?” because they expect the thesis to fit within one sentence, as it would in an average essay. For research papers, the answer is more complex.

For one, a research paper may not have a thesis at all. Instead, the introduction could hold research objectives or hypotheses. Whether you choose to postulate a thesis or ask a research question in a research paper, it doesn’t have to be as short as a single sentence. In most cases, a thesis fits within 2% to 5% of the word count threshold. So, for a 5,000-word project, it would cover between 100 and 250 words (up to one page). In most cases, when writing a research paper , a thesis should fit within one or two paragraphs, though you can also use a bulleted or numbered list for your objectives or tasks.

Important : When researching “How long is a research paper thesis?” remember that it’s not a separate section. Its word count goes towards the chapter that holds the thesis, usually an introduction or literature review. So, if your introduction is 500 words long, a thesis can take up around half of that.

Literature review

Like with other parts of the piece, there’s no definitive answer to “How long should a literature review be in a research paper?” General recommendations range from 15% to 30% of the research paper length. So, if your word count limit is 5,000 words, the literature review should span between 750 and 1,500 words (three to six pages). The more theoretical your research paper is, the longer your literature review can be. Experimental and empirical pieces may have shorter reviews. 

As always, if you’re unsure  “How long should a research paper be?” in terms of the literature review, you know the right answer to the question, ask your TA or professor.

Writing tip from SpeedyPaper

Depending on the layout of your piece, the answer to “How long should a conclusion be in a research paper?” varies between 5% and 10%. For instance, if you decide to combine the discussion section with the research paper conclusion or omit the former and outline the limitations and potential of your results within the final chapter, it will be longer. Alternatively, if your research paper conclusion will solely focus on rehashing the research objective and study results, the final section can be shorter.

For a research paper length of 5,000 words, the conclusion should be between 250 and 500 words (one or two pages). This does not include acknowledgments (if you decide to add them) or the reference list. Both are separate sections of research papers, and may not even be included in the general word count by some schools and journals. 

Research paper length by type

As we’ve established at the beginning of this post, “research paper” is a broad generic term that applies to many types of academic and scientific works you may encounter in college, grad school, or a doctoral program. Our calculations apply to a 5,000-word research paper , but you can use the same percentages for projects of different lengths, including:

• Research proposal — up to 3,000 words (12 pages)
• Case study — up to 5,000 words (20 pages)
• Term paper — up to 5,000 words (20 pages)
• Scientific publication — up to 15,000 words (60 pages)
• Capstone project — up to 30,000 words (100 pages)
• Thesis or dissertation — up to 100,000 words (400 pages)

Please note that these are averages based on our quick skim of research paper requirements across major US schools. Your college’s word count demands can be significantly lower or higher. So, we urge you to check in with your academic advisor, professor, or editor to double-check the word count expectations. 

How to meet research paper word count requirements: Tricks and strategies

Now that we’ve gone over the answer to “How long should a research paper be?”, let’s see if there are ways to reach the desired word count when you’re falling a bit short. Our expert academic writers shared a few of their favorite strategies:

• Use free writing . The brain dump method requires you to put as many ideas into words as possible without caring about proper sentence structure or spelling. You’ll inevitably write more than your research paper requires, but you can trim down the excess during editing. Besides, it’s a helpful trick for beating procrastination and writer’s block.
• Mix and match your sources . Instead of using protracted quotes to pad the research paper, provide evidence to support each claim from two or more sources . It will make your arguments seem stronger and earn the professor’s praise.
• Include logical transitions . It’s not just about transition phrases (i.e., at the same time, however, additionally, etc.) but also about building connections between individual paragraphs and subsections of the research paper. They’ll make your narrative smoother and pad the word count.
• Revise and add to completed parts . Unlike essay writing , research is a protracted and complex process that often involves going back and adjusting things. So don’t be afraid to expand certain sections of the project on your second go-through.

What factors influence the length requirement of a research paper?

Anything can affect the length of a research paper, from your academic level (undergraduate or graduate) and paper type to the class and topic. Your goal and audience will also influence the research paper’s word count requirements. For instance, if you want your piece to get noticed, you can dive deeper into the subject and hit the maximum word count limit instead of the minimum threshold.

Should I consider the word count or page count when determining paper length?

That depends on your research paper requirements. For example, professors typically assign research papers in pages, which include a title page, abstract, and references. Scientific journals, in turn, prefer to specify the word count requirements to ensure your entry fits editorial policies. One page is usually around 250 to 300 words (double-spaced, 12 pt font).

Can I adjust the length of my research paper during the writing process?

Large language model (LLM) systems, such as ChatGPT 1 or Gemini 2 , can show impressive reasoning and question-answering capabilities but often ‘hallucinate’ false outputs and unsubstantiated answers 3 , 4 . Answering unreliably or without the necessary information prevents adoption in diverse fields, with problems including fabrication of legal precedents 5 or untrue facts in news articles 6 and even posing a risk to human life in medical domains such as radiology 7 . Encouraging truthfulness through supervision or reinforcement has been only partially successful 8 . Researchers need a general method for detecting hallucinations in LLMs that works even with new and unseen questions to which humans might not know the answer. Here we develop new methods grounded in statistics, proposing entropy-based uncertainty estimators for LLMs to detect a subset of hallucinations—confabulations—which are arbitrary and incorrect generations. Our method addresses the fact that one idea can be expressed in many ways by computing uncertainty at the level of meaning rather than specific sequences of words. Our method works across datasets and tasks without a priori knowledge of the task, requires no task-specific data and robustly generalizes to new tasks not seen before. By detecting when a prompt is likely to produce a confabulation, our method helps users understand when they must take extra care with LLMs and opens up new possibilities for using LLMs that are otherwise prevented by their unreliability.

ThoughtSource: A central hub for large language model reasoning data

‘Hallucinations’ are a critical problem 9 for natural language generation systems using large language models (LLMs), such as ChatGPT 1 or Gemini 2 , because users cannot trust that any given output is correct.

Hallucinations are often defined as LLMs generating “content that is nonsensical or unfaithful to the provided source content” 9 , 10 , 11 but they have come to include a vast array of failures of faithfulness and factuality. We focus on a subset of hallucinations which we call ‘confabulations’ 12 for which LLMs fluently make claims that are both wrong and arbitrary—by which we mean that the answer is sensitive to irrelevant details such as random seed. For example, when asked a medical question “What is the target of Sotorasib?” an LLM confabulates by sometimes answering KRASG12 ‘C’ (correct) and other times KRASG12 ‘D’ (incorrect) despite identical instructions. We distinguish this from cases in which a similar ‘symptom’ is caused by the following different mechanisms: when LLMs are consistently wrong as a result of being trained on erroneous data such as common misconceptions 13 ; when the LLM ‘lies’ in pursuit of a reward 14 ; or systematic failures of reasoning or generalization. We believe that combining these distinct mechanisms in the broad category hallucination is unhelpful. Our method makes progress on a portion of the problem of providing scalable oversight 15 by detecting confabulations that people might otherwise find plausible. However, it does not guarantee factuality because it does not help when LLM outputs are systematically bad. Nevertheless, we significantly improve question-answering accuracy for state-of-the-art LLMs, revealing that confabulations are a great source of error at present.

We show how to detect confabulations by developing a quantitative measure of when an input is likely to cause an LLM to generate arbitrary and ungrounded answers. Detecting confabulations allows systems built on LLMs to avoid answering questions likely to cause confabulations, to make users aware of the unreliability of answers to a question or to supplement the LLM with more grounded search or retrieval. This is essential for the critical emerging field of free-form generation in which naive approaches, suited to closed vocabulary and multiple choice, fail. Past work on uncertainty for LLMs has focused on simpler settings, such as classifiers 16 , 17 and regressors 18 , 19 , whereas the most exciting applications of LLMs relate to free-form generations.

The term hallucination in the context of machine learning originally comes from filling in ungrounded details, either as a deliberate strategy 20 or as a reliability problem 4 . The appropriateness of the metaphor has been questioned as promoting undue anthropomorphism 21 . Although we agree that metaphor must be used carefully with LLMs 22 , the widespread adoption of the term hallucination reflects the fact that it points to an important phenomenon. This work represents a step towards making that phenomenon more precise.

To detect confabulations, we use probabilistic tools to define and then measure the ‘semantic’ entropy of the generations of an LLM—an entropy that is computed over meanings of sentences. High entropy corresponds to high uncertainty 23 , 24 , 25 —so semantic entropy is one way to estimate semantic uncertainties. Semantic uncertainty, the broader category of measures we introduce, could be operationalized with other measures of uncertainty, such as mutual information, instead. Entropy in free-form generation is normally hard to measure because answers might mean the same thing (be semantically equivalent) despite being expressed differently (being syntactically or lexically distinct). This causes naive estimates of entropy or other lexical variation scores 26 to be misleadingly high when the same correct answer might be written in many ways without changing its meaning.

By contrast, our semantic entropy moves towards estimating the entropy of the distribution of meanings of free-form answers to questions, insofar as that is possible, rather than the distribution over the ‘tokens’ (words or word-pieces) which LLMs natively represent. This can be seen as a kind of semantic consistency check 27 for random seed variation. An overview of our approach is provided in Fig. 1 and a worked example in Supplementary Table 1 .

a , Naive entropy-based uncertainty measures variation in the exact answers, treating ‘Paris’, ‘It’s Paris’ and ‘France’s capital Paris’ as different. But this is unsuitable for language tasks for which sometimes different answers mean the same things. Our semantic entropy clusters answers which share meanings before computing the entropy. A low semantic entropy shows that the LLM is confident about the meaning. b , Semantic entropy can also detect confabulations in longer passages. We automatically decompose a long generated answer into factoids. For each factoid, an LLM generates questions to which that factoid might have been the answer. The original LLM then samples  M possible answers to these questions. Finally, we compute the semantic entropy over the answers to each specific question, including the original factoid. Confabulations are indicated by high average semantic entropy for questions associated with that factoid. Here, semantic entropy classifies Fact 1 as probably not a confabulation because generations often mean the same thing, despite very different wordings, which a naive entropy would have missed.

Intuitively, our method works by sampling several possible answers to each question and clustering them algorithmically into answers that have similar meanings, which we determine on the basis of whether answers in the same cluster entail each other bidirectionally 28 . That is, if sentence A entails that sentence B is true and vice versa, then we consider them to be in the same semantic cluster. We measure entailment using both general-purpose LLMs and natural language inference (NLI) tools developed specifically for detecting entailment for which we show direct evaluations in Supplementary Tables 2 and 3 and Supplementary Fig. 1 . Textual entailment has previously been shown to correlate with faithfulness 10 in the context of factual consistency 29 as well as being used to measure factuality in abstractive summarization 30 , especially when applied at the right granularity 31 .

Semantic entropy detects confabulations in free-form text generation across a range of language models and domains, without previous domain knowledge. Our evaluations cover question answering in trivia knowledge (TriviaQA 32 ), general knowledge (SQuAD 1.1; ref. 33 ), life sciences (BioASQ 34 ) and open-domain natural questions (NQ-Open 35 ) derived from actual queries to Google Search 36 . In addition, semantic entropy detects confabulations in mathematical word problems (SVAMP 37 ) and in a biography-generation dataset, FactualBio, accompanying this paper.

Our results for TriviaQA, SQuAD, BioASQ, NQ-Open and SVAMP are all evaluated context-free and involve sentence-length answers (96 ± 70 characters, mean ± s.d.) and use LLaMA 2 Chat (7B, 13B and 70B parameters) 38 , Falcon Instruct (7B and 40B) 39 and Mistral Instruct (7B) 40 . In the Supplementary Information , we further consider short-phrase-length answers. Results for FactualBio (442 ± 122 characters) use GPT-4 (ref. 1 ). At the time of writing, GPT-4 (ref. 1 ) did not expose output probabilities 41 or hidden states, although it does now. As a result, we propose a discrete approximation of our estimator for semantic entropy which allows us to run experiments without access to output probabilities, which we use for all GPT-4 results in this paper and which performs similarly well.

Our confabulation detection with semantic entropy is more robust to user inputs from previously unseen domains than methods which aim to ‘learn’ how to detect confabulations from a set of example demonstrations. Our method is unsupervised, meaning that we do not need labelled examples of confabulations. By contrast, supervised methods detect confabulations by learning patterns behind examples of confabulations, assuming that future questions preserve these patterns. But this assumption is often untrue in new situations or with confabulations that human overseers are unable to identify (compare Fig. 17 of ref. 24 ). As a strong supervised baseline, we compare to an embedding regression method inspired by ref. 24 which trains a logistic regression classifier to predict whether the model correctly answered a question on the basis of the final ‘embedding’ (hidden state) of the LLM. We also use the P (True) method 24 which looks at the probability with which an LLM predicts that the next token is ‘True’ when few-shot prompted to compare a main answer with ‘brainstormed’ alternatives.

Confabulations contribute substantially to incorrect answers given by language models. We show that semantic entropy can be used to predict many incorrect model answers and to improve question-answering accuracy by refusing to answer those questions the model is uncertain about. Corresponding to these two uses, we evaluate two main metrics. First, the widely used area under the receiver operating characteristic (AUROC) curve for the binary event that a given answer is incorrect. This measure captures both precision and recall and ranges from 0 to 1, with 1 representing a perfect classifier and 0.5 representing an un-informative classifier. We also show a new measure, the area under the ‘rejection accuracy’ curve (AURAC). This studies the case in which the confabulation detection score is used to refuse to answer the questions judged most likely to cause confabulations. Rejection accuracy is the accuracy of the answers of the model on the remaining questions and the area under this curve is a summary statistic over many thresholds (representative threshold accuracies are provided in Supplementary Material ). The AURAC captures the accuracy improvement which users would experience if semantic entropy was used to filter out questions causing the highest entropy.

Detecting confabulations in QA and math

In Fig. 2 , we show that both semantic entropy and its discrete approximation outperform our best baselines for sentence-length generations. These results are averaged across datasets and provide the actual scores on the held-out evaluation dataset. We report the raw average score across held-out evaluation datasets without standard error because the distributional characteristics are more a property of the models and datasets selected than the method. Consistency of relative results across different datasets is a stronger indicator of variation in this case.

Semantic entropy outperforms leading baselines and naive entropy. AUROC (scored on the y -axes) measures how well methods predict LLM mistakes, which correlate with confabulations. AURAC (likewise scored on the y -axes) measures the performance improvement of a system that refuses to answer questions which are judged likely to cause confabulations. Results are an average over five datasets, with individual metrics provided in the Supplementary Information .

Semantic entropy greatly outperforms the naive estimation of uncertainty using entropy: computing the entropy of the length-normalized joint probability of the token sequences. Naive entropy estimation ignores the fact that token probabilities also express the uncertainty of the model over phrasings that do not change the meaning of an output.

Our methods also outperform the supervised embedding regression method both in- and out-of-distribution. In pale-yellow bars we show that embedding regression performance deteriorates when its training data do not match the deployment distribution—which mirrors the common real-world case in which there is a distribution shift between training and deployment 42 —the plotted value is the average metric for embedding regression trained on one of the four ‘off-distribution’ datasets for that evaluation. This is critical because reliable uncertainty is most important when the data distribution shifts. Semantic entropy also outperforms P (True) which is supervised ‘in-context’; that is, it is adapted to the deployment task with a few training examples provided in the LLM prompt itself. The discrete variant of semantic entropy performs similarly to our standard estimator, despite not requiring exact output probabilities.

Averaged across the 30 combinations of tasks and models we study, semantic entropy achieves the best AUROC value of 0.790 whereas naive entropy (0.691), P (True) (0.698) and the embedding regression baseline (0.687) lag behind it. Semantic entropy performs well consistently, with stable performance (between 0.78 and 0.81 AUROC) across the different model families (LLaMA, Falcon and Mistral) and scales (from 7B to 70B parameters) which we study (we report summary statistics for each dataset and model as before). Although semantic entropy outperforms the baselines across all model sizes, P (True) seems to improve with model size, suggesting that it might become more competitive for very capable honest models in settings that the model understands well (which are, however, not the most important cases to have good uncertainty). We use ten generations to compute entropy, selected using analysis in Supplementary Fig. 2 . Further results for short-phrase generations are described in Supplementary Figs. 7 – 10 .

The results in Fig. 2 offer a lower bound on the effectiveness of semantic entropy at detecting confabulations. These evaluations determine whether semantic entropy and baseline methods can detect when the answers of the model are incorrect (which we validate against human correctness evaluations in Supplementary Table 4 ). In addition to errors from confabulations (arbitrary incorrectness), this also includes other types of mistakes for which semantic entropy is not suited, such as consistent errors learned from the training data. The fact that methods such as embedding regression are able to spot other kinds of errors, not just confabulations, but still are outperformed by semantic entropy, suggests that confabulations are a principal category of errors for actual generations.

Examples of questions and answers from TriviaQA, SQuAD and BioASQ, for LLaMA 2 Chat 70B, are shown in Table 1 . These illustrate how only semantic entropy detects when the meaning is constant but the form varies (the first row of the table) whereas semantic entropy and naive entropy both correctly predict the presence of confabulations when the form and meaning vary together (second row) and predict the absence of confabulations when the form and meaning are both constant across several resampled generations (third row). In the final row, we give an example in which semantic entropy is erroneously high as a result of overly sensitive semantic clustering relative to the reference answer. Our clustering method distinguishes the answers which provide a precise date from those which only provide a year. For some contexts that would have been correct but in this context the distinction between the specific day and the year is probably irrelevant. This highlights the importance of context and judgement in clustering, especially in subtle cases, as well as the shortcomings of evaluating against fixed reference answers which do not capture the open-ended flexibility of conversational deployments of LLMs.

Detecting confabulations in biographies

Semantic entropy is most natural for sentences that express a single proposition but the idea of semantic equivalence is trickier to apply to longer passages which express many propositions which might only agree partially 43 . Nevertheless, we can use semantic entropy to detect confabulations in longer generations, such as entire paragraphs of text. To show this, we develop a dataset of biographical generations from GPT-4 (v.0613) for 21 individuals notable enough to have their own Wikipedia page but without extensive online biographies. From each biography generated by GPT-4, we automatically extract propositional factual claims about the individual (150 factual claims in total), which we manually label as true or false.

Applying semantic entropy to this problem is challenging. Naively, one might simply regenerate each sentence (conditioned on the text so far) and then compute semantic entropy over these regenerations. However, the resampled sentences often target different aspects of the biography: for example, one time describing family and the next time profession. This is analogous to the original problem semantic entropy was designed to resolve: the model is uncertain about the right ordering of facts, not about the facts themselves. To address this, we break down the entire paragraph into factual claims and reconstruct questions which might have been answered by those claims. Only then do we apply semantic entropy (Fig. 1 ) by generating three new answers to each question (selected with analysis in Supplementary Figs. 3 and 4 ) and computing the semantic entropy over those generations plus the original factual claim. We aggregate these by averaging the semantic entropy over all the questions to get an uncertainty score for each proposition, which we use to detect confabulations. Unaggregated results are shown in Supplementary Figs. 5 and 6 .

As GPT-4 did not allow access to the probability of the generation at the time of writing, we use a discrete variant of semantic entropy which makes the further approximation that we can infer a discrete empirical distribution over semantic meaning clusters from only the generations ( Methods ). This allows us to compute semantic entropy using only the black-box outputs of an LLM. However, we were unable to compute the naive entropy baseline, the standard semantic entropy estimator or the embedding regression baseline for GPT-4 without output probabilities and embeddings.

In Fig. 3 we show that the discrete variant of semantic entropy effectively detects confabulations on this dataset. Its AUROC and AURAC are higher than either a simple ‘self-check’ baseline—which just asks the LLM whether the factoid is likely to be true—or a variant of P (True) which has been adapted to work for the paragraph-length setting. Discrete semantic entropy has better rejection accuracy performance until 20% of the questions have been rejected at which point P (True) has a narrow edge. This indicates that the questions predicted to cause confabulations are indeed more likely to be wrong.

The discrete variant of our semantic entropy estimator outperforms baselines both when measured by AUROC and AURAC metrics (scored on the y -axis). The AUROC and AURAC are substantially higher than for both baselines. At above 80% of questions being answered, semantic entropy has the highest accuracy. Only when the top 20% of answers judged most likely to be confabulations are rejected does the answer accuracy on the remainder for the P (True) baseline exceed semantic entropy.

Our probabilistic approach, accounting for semantic equivalence, detects an important class of hallucinations: those that are caused by a lack of LLM knowledge. These are a substantial portion of the failures at present and will continue even as models grow in capabilities because situations and cases that humans cannot reliably supervise will persist. Confabulations are a particularly noteworthy failure mode for question answering but appear in other domains too. Semantic entropy needs no previous domain knowledge and we expect that algorithmic adaptations to other problems will allow similar advances in, for example, abstractive summarization. In addition, extensions to alternative input variations such as rephrasing or counterfactual scenarios would allow a similar method to act as a form of cross-examination 44 for scalable oversight through debate 45 .

The success of semantic entropy at detecting errors suggests that LLMs are even better at “knowing what they don’t know” than was argued by ref. 24 —they just don’t know they know what they don’t know. Our method explicitly does not directly address situations in which LLMs are confidently wrong because they have been trained with objectives that systematically produce dangerous behaviour, cause systematic reasoning errors or are systematically misleading the user. We believe that these represent different underlying mechanisms—despite similar ‘symptoms’—and need to be handled separately.

One exciting aspect of our approach is the way it makes use of classical probabilistic machine learning methods and adapts them to the unique properties of modern LLMs and free-form language generation. We hope to inspire a fruitful exchange of well-studied methods and emerging new problems by highlighting the importance of meaning when addressing language-based machine learning problems.

Semantic entropy as a strategy for overcoming confabulation builds on probabilistic tools for uncertainty estimation. It can be applied directly to any LLM or similar foundation model without requiring any modifications to the architecture. Our ‘discrete’ variant of semantic uncertainty can be applied even when the predicted probabilities for the generations are not available, for example, because access to the internals of the model is limited.

In this section we introduce background on probabilistic methods and uncertainty in machine learning, discuss how it applies to language models and then discuss our contribution, semantic entropy, in detail.

Uncertainty and machine learning

We aim to detect confabulations in LLMs, using the principle that the model will be uncertain about generations for which its output is going to be arbitrary.

One measure of uncertainty is the predictive entropy of the output distribution, which measures the information one has about the output given the input 25 . The predictive entropy (PE) for an input sentence x is the conditional entropy ( H ) of the output random variable Y with realization y given x ,

A low predictive entropy indicates an output distribution which is heavily concentrated whereas a high predictive entropy indicates that many possible outputs are similarly likely.

Aleatoric and epistemic uncertainty

We do not distinguish between aleatoric and epistemic uncertainty in our analysis. Researchers sometimes separate aleatoric uncertainty (uncertainty in the underlying data distribution) from epistemic uncertainty (caused by having only limited information) 46 . Further advances in uncertainty estimation which separate these kinds of uncertainty would enhance the potential for our semantic uncertainty approach by allowing extensions beyond entropy.

Joint probabilities of sequences of tokens

Generative LLMs produce strings of text by selecting tokens in sequence. Each token is a wordpiece that often represents three or four characters (though especially common sequences and important words such as numbers typically get their own token). To compute entropies, we need access to the probabilities the LLM assigns to the generated sequence of tokens. The probability of the entire sequence, s , conditioned on the context, x , is the product of the conditional probabilities of new tokens given past tokens, whose resulting log-probability is \(\log P({\bf{s}}| {\boldsymbol{x}})={\sum }_{i}\log P({s}_{i}| {{\bf{s}}}_{ < i},{\boldsymbol{x}})\) , where s i is the i th output token and s < i denotes the set of previous tokens.

Length normalization

When comparing the log-probabilities of generated sequences, we use ‘length normalization’, that is, we use an arithmetic mean log-probability, \(\frac{1}{N}{\sum }_{i}^{N}\log P({s}_{i}| {{\bf{s}}}_{ < i},{\boldsymbol{x}})\) , instead of the sum. In expectation, longer sequences have lower joint likelihoods because of the conditional independence of the token probabilities 47 . The joint likelihood of a sequence of length N shrinks exponentially in N . Its negative log-probability therefore grows linearly in N , so longer sentences tend to contribute more to entropy. We therefore interpret length-normalizing the log-probabilities when estimating the entropy as asserting that the expected uncertainty of generations is independent of sentence length. Length normalization has some empirical success 48 , including in our own preliminary experiments, but little theoretical justification in the literature.

Principles of semantic uncertainty

If we naively calculate the predictive entropy directly from the probabilities of the generated sequence of tokens, we conflate the uncertainty of the model over the meaning of its answer with the uncertainty over the exact tokens used to express that meaning. For example, even if the model is confident in the meaning of a generation, there are still usually many different ways for phrasing that generation without changing its meaning. For the purposes of detecting confabulations, the uncertainty of the LLM over meanings is more important than the uncertainty over the exact tokens used to express those meanings.

Our semantic uncertainty method therefore seeks to estimate only the uncertainty the LLM has over the meaning of its generation, not the choice of words. To do this, we introduce an algorithm that clusters model generations by meaning and subsequently calculates semantic uncertainty. At a high level this involves three steps:

Generation: sample output sequences of tokens from the predictive distribution of a LLM given a context x .

Clustering: cluster sequences by their meaning using our clustering algorithm based on bidirectional entailment.

Entropy estimation: estimate semantic entropy by summing probabilities of sequences that share a meaning following equation ( 2 ) and compute their entropy.

Generating a set of answers from the model

Given some context x as input to the LLM, we sample M sequences, { s (1) , …,  s ( M ) } and record their token probabilities, { P ( s (1) ∣ x ), …,  P ( s ( M ) ∣ x )}. We sample all our generations from a single model, varying only the random seed used for sampling from the token probabilities. We do not observe the method to be particularly sensitive to details of the sampling scheme. In our implementation, we sample at temperature 1 using nucleus sampling ( P  = 0.9) (ref. 49 ) and top- K sampling ( K  = 50) (ref. 50 ). We also sample a single generation at low temperature (0.1) as an estimate of the ‘best generation’ of the model to the context, which we use to assess the accuracy of the model. (A lower sampling temperature increases the probability of sampling the most likely tokens).

Clustering by semantic equivalence

To estimate semantic entropy we need to cluster generated outputs from the model into groups of outputs that mean the same thing as each other.

This can be described using ‘semantic equivalence’ which is the relation that holds between two sentences when they mean the same thing. We can formalize semantic equivalence mathematically. Let the space of tokens in a language be \({\mathcal{T}}\) . The space of all possible sequences of tokens of length N is then \({{\mathcal{S}}}_{N}\equiv {{\mathcal{T}}}^{N}\) . Note that N can be made arbitrarily large to accommodate whatever size of sentence one can imagine and one of the tokens can be a ‘padding’ token which occurs with certainty for each token after the end-of-sequence token. For some sentence \({\bf{s}}\in {{\mathcal{S}}}_{N}\) , composed of a sequence of tokens, \({s}_{i}\in {\mathcal{T}}\) , there is an associated meaning. Theories of meaning are contested 51 . However, for specific models and deployment contexts many considerations can be set aside. Care should be taken comparing very different models and contexts.

Let us introduce a semantic equivalence relation, E (  ⋅  ,  ⋅  ), which holds for any two sentences that mean the same thing—we will operationalize this presently. Recall that an equivalence relation is any reflexive, symmetric and transitive relation and that any equivalence relation on a set corresponds to a set of equivalence classes. Each semantic equivalence class captures outputs that can be considered to express the same meaning. That is, for the space of semantic equivalence classes \({\mathcal{C}}\) the sentences in the set \(c\in {\mathcal{C}}\) can be regarded in many settings as expressing a similar meaning such that \(\forall {\bf{s}},{{\bf{s}}}^{{\prime} }\in c:E({\bf{s}},{{\bf{s}}}^{{\prime} })\) . So we can build up these classes of semantically equivalent sentences by checking if new sentences share a meaning with any sentences we have already clustered and, if so, adding them into that class.

We operationalize E (  ⋅  ,  ⋅  ) using the idea of bidirectional entailment, which has a long history in linguistics 52 and natural language processing 28 , 53 , 54 . A sequence, s , means the same thing as a second sequence, s ′, only if the sequences entail (that is, logically imply) each other. For example, ‘The capital of France is Paris’ entails ‘Paris is the capital of France’ and vice versa because they mean the same thing. (See later for a discussion of soft equivalence and cases in which bidirectional entailment does not guarantee equivalent meanings).

Importantly, we require that the sequences mean the same thing with respect to the context—key meaning is sometimes contained in the context. For example, ‘Paris’ does not entail ‘The capital of France is Paris’ because ‘Paris’ is not a declarative sentence without context. But in the context of the question ‘What is the capital of France?’, the one-word answer does entail the longer answer.

Detecting entailment has been the object of study of a great deal of research in NLI 55 . We rely on language models to predict entailment, such as DeBERTa-Large-MNLI 56 , which has been trained to predict entailment, or general-purpose LLMs such as GPT-3.5 (ref. 57 ), which can predict entailment given suitable prompts.

We then cluster sentences according to whether they bidirectionally entail each other using the algorithm presented in Extended Data Fig. 1 . Note that, to check if a sequence should be added to an existing cluster, it is sufficient to check if the sequence bidirectionally entails any of the existing sequences in that cluster (we arbitrarily pick the first one), given the transitivity of semantic equivalence. If a sequence does not share meaning with any existing cluster, we assign it its own cluster.

Computing the semantic entropy

Having determined the classes of generated sequences that mean the same thing, we can estimate the likelihood that a sequence generated by the LLM belongs to a given class by computing the sum of the probabilities of all the possible sequences of tokens which can be considered to express the same meaning as

Formally, this treats the output as a random variable whose event-space is the space of all possible meaning-classes, C , a sub- σ -algebra of the standard event-space S . We can then estimate the semantic entropy (SE) as the entropy over the meaning-distribution,

There is a complication which prevents direct computation: we do not have access to every possible meaning-class c . Instead, we can only sample c from the sequence-generating distribution induced by the model. To handle this, we estimate the expectation in equation ( 3 ) using a Rao–Blackwellized Monte Carlo integration over the semantic equivalence classes C ,

where \(P({C}_{i}| {\boldsymbol{x}})=\frac{P({c}_{i}| {\boldsymbol{x}})}{{\sum }_{c}P(c| {\boldsymbol{x}})}\) estimates a categorical distribution over the cluster meanings, that is, ∑ i P ( C i ∣ x ) = 1. Without this normalization step cluster ‘probabilities’ could exceed one because of length normalization, resulting in degeneracies. Equation ( 5 ) is the estimator giving our main method that we refer to as semantic entropy throughout the text.

For scenarios in which the sequence probabilities are not available, we propose a variant of semantic entropy which we call ‘discrete’ semantic entropy. Discrete semantic entropy approximates P ( C i ∣ x ) directly from the number of generations in each cluster, disregarding the token probabilities. That is, we approximate P ( C i ∣ x ) as \({\sum }_{1}^{M}\frac{{I}_{c={C}_{i}}}{M}\) , the proportion of all the sampled answers which belong to that cluster. Effectively, this just assumes that each output that was actually generated was equally probable—estimating the underlying distribution as the categorical empirical distribution. In the limit of M the estimator converges to equation ( 5 ) by the law of large numbers. We find that discrete semantic entropy results in similar performance empirically.

We provide a worked example of the computation of semantic entropy in Supplementary Note  1 .

Semantic entropy is designed to detect confabulations, that is, model outputs with arbitrary meaning. In our experiments, we use semantic uncertainty to predict model accuracy, demonstrating that confabulations make up a notable fraction of model mistakes. We further show that semantic uncertainty can be used to improve model accuracy by refusing to answer questions when semantic uncertainty is high. Last, semantic uncertainty can be used to give users a way to know when model generations are probably unreliable.

We use the datasets BioASQ 34 , SQuAD 33 , TriviaQA 32 , SVAMP 37 and NQ-Open 35 . BioASQ is a life-sciences question-answering dataset based on the annual challenge of the same name. The specific dataset we use is based on the QA dataset from Task B of the 2023 BioASQ challenge (11B). SQuAD is a reading comprehension dataset whose context passages are drawn from Wikipedia and for which the answers to questions can be found in these passages. We use SQuAD 1.1 which excludes the unanswerable questions added in v.2.0 that are deliberately constructed to induce mistakes so they do not in practice cause confabulations to occur. TriviaQA is a trivia question-answering dataset. SVAMP is a word-problem maths dataset containing elementary-school mathematical reasoning tasks. NQ-Open is a dataset of realistic questions aggregated from Google Search which have been chosen to be answerable without reference to a source text. For each dataset, we use 400 train examples and 400 test examples randomly sampled from the original larger dataset. Note that only some of the methods require training, for example semantic entropy does not use the training data. If the datasets themselves are already split into train and test (or validation) samples, we sample our examples from within the corresponding split.

All these datasets are free-form, rather than multiple choice, because this better captures the opportunities created by LLMs to produce free-form sentences as answers. We refer to this default scenario as our ‘sentence-length’ experiments. In Supplementary Note  7 , we also present results for confabulation detection in a ‘short-phrase’ scenario, in which we constrain model answers on these datasets to be as concise as possible.

To make the problems more difficult and induce confabulations, we do not provide the context passages for any of the datasets. When the context passages are provided, the accuracy rate is too high for these datasets for the latest generations of models to meaningfully study confabulations.

For sentence-length generations we use: Falcon 39 Instruct (7B and 40B), LLaMA 2 Chat 38 (7B, 13B and 70B) and Mistral 40 Instruct (7B).

In addition to reporting results for semantic entropy, discrete semantic entropy and naive entropy, we consider two strong baselines.

Embedding regression is a supervised baseline inspired by the P (IK) method 24 . In that paper, the authors fine-tune their proprietary LLM on a dataset of questions to predict whether the model would have been correct. This requires access to a dataset of ground-truth answers to the questions. Rather than fine-tuning the entire LLM in this way, we simply take the final hidden units and train a logistic regression classifier to make the same prediction. By contrast to their method, this is much simpler because it does not require fine-tuning the entire language model, as well as being more reproducible because the solution to the logistic regression optimization problem is not as seed-dependent as the fine-tuning procedure. As expected, this supervised approach performs well in-distribution but fails when the distribution of questions is different from that on which the classifier is trained.

The second baseline we consider is the P (True) method 24 , in which the model first samples M answers (identically to our semantic entropy approach) and then is prompted with the list of all answers generated followed by the highest probability answer and a question whether this answer is “(a) True” or “(b) False”. The confidence score is then taken to be the probability with which the LLM responds with ‘a’ to the multiple-choice question. The performance of this method is boosted with a few-shot prompt, in which up to 20 examples from the training set are randomly chosen, filled in as above, but then provided with the actual ground truth of whether the proposed answer was true or false. In this way, the method can be considered as supervised ‘in-context’ because it makes use of some ground-truth training labels but can be used without retraining the model. Because of context-size constraints, this method cannot fit a full 20 few-shot examples in the context when input questions are long or large numbers of generations are used. As a result, we sometimes have to reduce the number of few-shot examples to suit the context size and we note this in the  Supplementary Material .

Entailment estimator

Any NLI classification system could be used for our bidirectional entailment clustering algorithm. We consider two different kinds of entailment detector.

One option is to use an instruction-tuned LLM such as LLaMA 2, GPT-3.5 (Turbo 1106) or GPT-4 to predict entailment between generations. We use the following prompt:

We are evaluating answers to the question {question} Here are two possible answers: Possible Answer 1: {text1} Possible Answer 2: {text2} Does Possible Answer 1 semantically entail Possible Answer 2? Respond with entailment, contradiction, or neutral.

Alternatively, we consider using a language model trained for entailment prediction, specifically the DeBERTa-large model 56 fine-tuned on the NLI dataset MNLI 58 . This builds on past work towards paraphrase identification based on embedding similarity 59 , 60 and BERT-style models 61 , 62 . We template more simply, checking if DeBERTa predicts entailment between the concatenation of the question and one answer and the concatenation of the question and another answer. Note that DeBERTa-large is a relatively lightweight model with only 1.5B parameters which is much less powerful than most of the LLMs under study.

In Supplementary Note 2 , we carefully evaluate the benefits and drawbacks of these methods for entailment prediction. We settle on using GPT-3.5 with the above prompt, as its entailment predictions agree well with human raters and lead to good confabulation detection performance.

In Supplementary Note  3 , we provide a discussion of the computational cost and choosing the number of generations for reliable clustering.

Prompting templates

We use a simple generation template for all sentence-length answer datasets:

Answer the following question in a single brief but complete sentence. Question: {question} Answer:

Metrics and accuracy measurements

We use three main metrics to evaluate our method: AUROC, rejection accuracy and AURAC. Each of these is grounded in an automated factuality estimation measurement relative to the reference answers provided by the datasets that we use.

AUROC, rejection accuracy and AURAC

First, we use the AUROC curve, which measures the reliability of a classifier accounting for both precision and recall. The AUROC can be interpreted as the probability that a randomly chosen correct answer has been assigned a higher confidence score than a randomly chosen incorrect answer. For a perfect classifier, this is 1.

Second, we compute the ‘rejection accuracy at X %’, which is the question-answering accuracy of the model on the most-confident X % of the inputs as identified by the respective uncertainty method. If an uncertainty method works well, predictions on the confident subset should be more accurate than predictions on the excluded subset and the rejection accuracy should increase as we reject more inputs.

To summarize this statistic we compute the AURAC—the total area enclosed by the accuracies at all cut-off percentages X %. This should increase towards 1 as given uncertainty method becomes more accurate and better at detecting likely-inaccurate responses but it is more sensitive to the overall accuracy of the model than the AUROC metric.

In Supplementary Note  5 , we provide the unaggregated rejection accuracies for sentence-length generations.

Assessing accuracy

For the short-phrase-length generation setting presented in Supplementary Note  7 , we simply assess the accuracy of the generations by checking if the F1 score of the commonly used SQuAD metric exceeds 0.5. There are limitations to such simple scoring rules 63 but this method is widely used in practice and its error is comparatively small on these standard datasets.

For our default scenario, the longer sentence-length generations, this measure fails, as the overlap between the short reference answer and our long model answer is invariably too small. For sentence-length generations, we therefore automatically determine whether an answer to the question is correct or incorrect by using GPT-4 to compare the given answer to the reference answer. We use the template:

We are assessing the quality of answers to the following question: {question} The expected answer is: {reference answer} The proposed answer is: {predicted answer} Within the context of the question, does the proposed answer mean the same as the expected answer? Respond only with yes or no.

We make a small modification for datasets with several reference answers: line two becomes “The following are expected answers to this question:” and the final line asks “does the proposed answer mean the same as any of the expected answers?”.

In Supplementary Note 6 , we check the quality of our automated ground-truth evaluations against human judgement by hand. We find that GPT-4 gives the best results for determining model accuracy and thus use it in all our sentence-length experiments.

In this section we describe the application of semantic entropy to confabulation detection in longer model generations, specifically paragraph-length biographies.

We introduce a biography-generation dataset—FactualBio—available alongside this paper. FactualBio is a collection of biographies of individuals who are notable enough to have Wikipedia pages but not notable enough to have large amounts of detailed coverage, generated by GPT-4 (v.0613). To generate the dataset, we randomly sampled 21 individuals from the WikiBio dataset 64 . For each biography, we generated a list of factual claims contained in each biography using GPT-4, with 150 total factual claims (the total number is only coincidentally a round number). For each of these factual claims, we manually determined whether the claim was correct or incorrect. Out of 150 claims, 45 were incorrect. As before, we apply confabulation detection to detect incorrect model predictions, even though there may be model errors which are not confabulations.

Prompting and generation

Given a paragraph-length piece of LLM-generated text, we apply the following sequence of steps:

Automatically decompose the paragraph into specific factual claims using an LLM (not necessarily the same as the original).

For each factual claim, use an LLM to automatically construct Q questions which might have produced that claim.

For each question, prompt the original LLM to generate M answers.

For each question, compute the semantic entropy of the answers, including the original factual claim.

Average the semantic entropies over the questions to arrive at a score for the original factual claim.

We pursue this slightly indirect way of generating answers because we find that simply resampling each sentence creates variation unrelated to the uncertainty of the model about the factual claim, such as differences in paragraph structure.

We decompose the paragraph into factual claims using the following prompt:

Please list the specific factual propositions included in the answer above. Be complete and do not leave any factual claims out. Provide each claim as a separate sentence in a separate bullet point.

We found that we agreed with the decompositions in all cases in the dataset.

We then generate six questions for each of the facts from the decomposition. We generate these questions by prompting the model twice with the following:

Following this text: {text so far} You see the sentence: {proposition} Generate a list of three questions, that might have generated the sentence in the context of the preceding original text, as well as their answers. Please do not use specific facts that appear in the follow-up sentence when formulating the question. Make the questions and answers diverse. Avoid yes-no questions. The answers should not be a full sentence and as short as possible, e.g. only a name, place, or thing. Use the format “1. {question} – {answer}”.

These questions are not necessarily well-targeted and the difficulty of this step is the main source of errors in the procedure. We generate three questions with each prompt, as this encourages diversity of the questions, each question targeting a different aspect of the fact. However, we observed that the generated questions will sometimes miss obvious aspects of the fact. Executing the above prompt twice (for a total of six questions) can improve coverage. We also ask for brief answers because the current version of GPT-4 tends to give long, convoluted and highly hedged answers unless explicitly told not to.

Then, for each question, we generate three new answers using the following prompt:

We are writing an answer to the question “{user question}”. So far we have written: {text so far} The next sentence should be the answer to the following question: {question} Please answer this question. Do not answer in a full sentence. Answer with as few words as possible, e.g. only a name, place, or thing.

We then compute the semantic entropy over these answers plus the original factual claim. Including the original fact ensures that the estimator remains grounded in the original claim and helps detect situations in which the question has been interpreted completely differently from the original context. We make a small modification to handle the fact that GPT-4 generations often include refusals to answer questions. These refusals were not something we commonly observe in our experiments with LLaMA 2, Falcon or Mistral models. If more than half of the answers include one of the strings ‘not available’, ‘not provided’, ‘unknown’ or ‘unclear’ then we treat the semantic uncertainty as maximal.

We then average the semantic entropies for each question corresponding to the factual claim to get an entropy for this factual claim.

Despite the extra assumptions and complexity, we find that this method greatly outperforms the baselines.

To compute semantic entailment between the original claim and regenerated answers, we rely on the DeBERTa entailment prediction model as we find empirically that DeBERTa predictions result in higher train-set AUROC than other methods. Because DeBERTa has slightly lower recall than GPT-3.5/4, we use a modified set-up for which we say the answers mean the same as each other if at least one of them entails the other and neither is seen to contradict the other—a kind of ‘non-defeating’ bidirectional entailment check rather than true bidirectional entailment. The good performance of DeBERTa in this scenario is not surprising as both factual claims and regenerated answers are relatively short. We refer to Supplementary Notes 2 and 3 for ablations and experiments regarding our choice of entailment estimator for paragraph-length generations.

We implement two baselines. First, we implement a variant of the P (True) method, which is adapted to the new setting. For each factoid, we generate a question with answers in the same way as for semantic entropy. We then use the following prompt:

Question: {question} Here are some brainstormed ideas: {list of regenerated answers} Possible answer: {original answer} Is the possible answer true? Respond with “yes” or “no”.

As we cannot access the probabilities GPT-4 assigns to predicting ‘yes’ and ‘no’ as the next token, we approximate this using Monte Carlo samples. Concretely, we execute the above prompt ten times (at temperature 1) and then take the fraction of answers which was ‘yes’ as our unbiased Monte Carlo estimate of the token probability GPT-4 assigns to ‘yes’.

As a second, simpler, baseline we check if the model thinks the answer is true. We simply ask:

Following this text: {text so far} You see this statement: {proposition} Is it likely that the statement is true? Respond with ‘yes’ or ‘no’.

It is interesting that this method ought to perform very well if we think that the model has good ‘self-knowledge’ (that is, if “models mostly know what they don’t know” 24 ) but in fact semantic entropy is much better at detecting confabulations.

S.F. led the work from conception to completion and proposed using bidirectional entailment to cluster generations as a way of computing entropy in LLMs. He wrote the main text, most of the Methods and Supplementary Information and prepared most of the figures. J.K. improved the mathematical formalization of semantic entropy; led the extension of semantic entropy to sentence- and paragraph-length generations; wrote the code for, and carried out, all the experiments and evaluations; wrote much of the Methods and Supplementary Information and prepared drafts of many figures; and gave critical feedback on the main text. L.K. developed the initial mathematical formalization of semantic entropy; wrote code for, and carried out, the initial experiments around semantic entropy and its variants which demonstrated the promise of the idea and helped narrow down possible research avenues to explore; and gave critical feedback on the main text. Y.G. ideated the project, proposing the idea to differentiate semantic and syntactic diversity as a tool for detecting hallucinations, provided high-level guidance on the research and gave critical feedback on the main text; he runs the research laboratory in which the work was carried out.
