What is a ‘gap in the literature’?

The gap, also considered the missing piece or pieces in the research literature, is the area that has not yet been explored or is under-explored. This could be a population or sample (size, type, location, etc.), research method, data collection and/or analysis, or other research variables or conditions.

It is important to keep in mind, however, that just because you identify a gap in the research, it doesn't necessarily mean that your research question is worthy of exploration. You will want to make sure that your research will have valuable practical and/or theoretical implications. In other words, answering the research question could either improve existing practice and/or inform professional decision-making (Applied Degree), or it could revise, build upon, or create theoretical frameworks informing research design and practice (Ph.D Degree). See the Dissertation Center  for additional information about dissertation criteria at NU.

For a additional information on gap statements, see the following:

  • How to Find a Gap in the Literature
  • Write Like a Scientist: Gap Statements

How do you identify the gaps?

Conducting an exhaustive literature review is your first step. As you search for journal articles, you will need to read critically across the breadth of the literature to identify these gaps. You goal should be to find a ‘space’ or opening for contributing new research. The first step is gathering a broad range of research articles on your topic. You may want to look for research that approaches the topic from a variety of methods – qualitative, quantitative, or mixed methods. 

See the videos below for further instruction on identifying a gap in the literature.

Identifying a Gap in the Literature - Dr. Laurie Bedford

How Do You Identify Gaps in Literature? - SAGE Research Methods

Literature Gap & Future Research - Library Workshop

This workshop presents effective search techniques for identifying a gap in the literature and recommendations for future research.

Where can you locate research gaps?

As you begin to gather the literature, you will want to critically read for what has, and has not, been learned from the research. Use the Discussion and Future Research sections of the articles to understand what the researchers have found and where they point out future or additional research areas. This is similar to identifying a gap in the literature, however, future research statements come from a single study rather than an exhaustive search. You will want to check the literature to see if those research questions have already been answered.

Screenshot of an article PDF with the "Suggestions for Future Research and Conclusion" section highlighted.

Roadrunner Search

Identifying the gap in the research relies on an exhaustive review of the literature. Remember, researchers may not explicitly state that a gap in the literature exists; you may need to thoroughly review and assess the research to make that determination yourself.

However, there are techniques that you can use when searching in NavigatorSearch to help identify gaps in the literature. You may use search terms such as "literature gap " or "future research" "along with your subject keywords to pinpoint articles that include these types of statements.

The Research Gap (Literature Gap)

Everything you need to know to find a quality research gap

By: Ethar Al-Saraf (PhD) | Expert Reviewed By: Eunice Rautenbach (DTech) | November 2022

If you’re just starting out in research, chances are you’ve heard about the elusive research gap (also called a literature gap). In this post, we’ll explore the tricky topic of research gaps. We’ll explain what a research gap is, look at the four most common types of research gaps, and unpack how you can go about finding a suitable research gap for your dissertation, thesis or research project.

Overview: Research Gap 101

  • What is a research gap
  • Four common types of research gaps
  • How to find research gaps
  • Recap & key takeaways

What (exactly) is a research gap?

Well, at the simplest level, a research gap is essentially an unanswered question or unresolved problem in a field, which reflects a lack of existing research in that space. Alternatively, a research gap can also exist when there’s already a fair deal of existing research, but where the findings of the studies pull in different directions , making it difficult to draw firm conclusions.

For example, let’s say your research aims to identify the cause (or causes) of a particular disease. Upon reviewing the literature, you may find that there’s a body of research that points toward cigarette smoking as a key factor – but at the same time, a large body of research that finds no link between smoking and the disease. In that case, you may have something of a research gap that warrants further investigation.

Now that we’ve defined what a research gap is – an unanswered question or unresolved problem – let’s look at a few different types of research gaps.

A research gap is essentially an unanswered question or unresolved problem in a field, reflecting a lack of existing research.

The different types of research gaps

While there are many different types of research gaps, the four most common ones we encounter when helping students at Grad Coach are as follows:

  • The classic literature gap
  • The disagreement gap
  • The contextual gap, and
  • The methodological gap

Need a helping hand?

research gap in literature review

1. The Classic Literature Gap

First up is the classic literature gap. This type of research gap emerges when there’s a new concept or phenomenon that hasn’t been studied much, or at all. For example, when a social media platform is launched, there’s an opportunity to explore its impacts on users, how it could be leveraged for marketing, its impact on society, and so on. The same applies for new technologies, new modes of communication, transportation, etc.

Classic literature gaps can present exciting research opportunities , but a drawback you need to be aware of is that with this type of research gap, you’ll be exploring completely new territory . This means you’ll have to draw on adjacent literature (that is, research in adjacent fields) to build your literature review, as there naturally won’t be very many existing studies that directly relate to the topic. While this is manageable, it can be challenging for first-time researchers, so be careful not to bite off more than you can chew.

2. The Disagreement Gap

As the name suggests, the disagreement gap emerges when there are contrasting or contradictory findings in the existing research regarding a specific research question (or set of questions). The hypothetical example we looked at earlier regarding the causes of a disease reflects a disagreement gap.

Importantly, for this type of research gap, there needs to be a relatively balanced set of opposing findings . In other words, a situation where 95% of studies find one result and 5% find the opposite result wouldn’t quite constitute a disagreement in the literature. Of course, it’s hard to quantify exactly how much weight to give to each study, but you’ll need to at least show that the opposing findings aren’t simply a corner-case anomaly .

3. The Contextual Gap

The third type of research gap is the contextual gap. Simply put, a contextual gap exists when there’s already a decent body of existing research on a particular topic, but an absence of research in specific contexts .

For example, there could be a lack of research on:

  • A specific population – perhaps a certain age group, gender or ethnicity
  • A geographic area – for example, a city, country or region
  • A certain time period – perhaps the bulk of the studies took place many years or even decades ago and the landscape has changed.

The contextual gap is a popular option for dissertations and theses, especially for first-time researchers, as it allows you to develop your research on a solid foundation of existing literature and potentially even use existing survey measures.

Importantly, if you’re gonna go this route, you need to ensure that there’s a plausible reason why you’d expect potential differences in the specific context you choose. If there’s no reason to expect different results between existing and new contexts, the research gap wouldn’t be well justified. So, make sure that you can clearly articulate why your chosen context is “different” from existing studies and why that might reasonably result in different findings.

4. The Methodological Gap

Last but not least, we have the methodological gap. As the name suggests, this type of research gap emerges as a result of the research methodology or design of existing studies. With this approach, you’d argue that the methodology of existing studies is lacking in some way , or that they’re missing a certain perspective.

For example, you might argue that the bulk of the existing research has taken a quantitative approach, and therefore there is a lack of rich insight and texture that a qualitative study could provide. Similarly, you might argue that existing studies have primarily taken a cross-sectional approach , and as a result, have only provided a snapshot view of the situation – whereas a longitudinal approach could help uncover how constructs or variables have evolved over time.

How To Find A Research Gap

Now that you’ve got a clearer picture of the different types of research gaps, the next question is of course, “how do you find these research gaps?” .

Well, we cover the process of how to find original, high-value research gaps in a separate post . But, for now, I’ll share a basic two-step strategy here to help you find potential research gaps.

As a starting point, you should find as many literature reviews, systematic reviews and meta-analyses as you can, covering your area of interest. Additionally, you should dig into the most recent journal articles to wrap your head around the current state of knowledge. It’s also a good idea to look at recent dissertations and theses (especially doctoral-level ones). Dissertation databases such as ProQuest, EBSCO and Open Access are a goldmine for this sort of thing. Importantly, make sure that you’re looking at recent resources (ideally those published in the last year or two), or the gaps you find might have already been plugged by other researchers.

Once you’ve gathered a meaty collection of resources, the section that you really want to focus on is the one titled “ further research opportunities ” or “further research is needed”. In this section, the researchers will explicitly state where more studies are required – in other words, where potential research gaps may exist. You can also look at the “ limitations ” section of the studies, as this will often spur ideas for methodology-based research gaps.

By following this process, you’ll orient yourself with the current state of research , which will lay the foundation for you to identify potential research gaps. You can then start drawing up a shortlist of ideas and evaluating them as candidate topics . But remember, make sure you’re looking at recent articles – there’s no use going down a rabbit hole only to find that someone’s already filled the gap 🙂

Let’s Recap

We’ve covered a lot of ground in this post. Here are the key takeaways:

  • A research gap is an unanswered question or unresolved problem in a field, which reflects a lack of existing research in that space.
  • The four most common types of research gaps are the classic literature gap, the disagreement gap, the contextual gap and the methodological gap. 
  • To find potential research gaps, start by reviewing recent journal articles in your area of interest, paying particular attention to the FRIN section .

Gaps in the literature.

Gaps in the literature are missing pieces or insufficient information in the published research on a topic. These are areas that have opportunities for further research because they are unexplored, under-explored, or outdated. 

Finding Gaps

Gaps can be missing or incomplete:

  • Population or sample: size, type, location etc…
  • Research methods: qualitative, quantitative, or mixed
  • Data collection or analysis
  • Research variables or conditions

Conduct a thorough literature search to find a broad range of research articles on your topic. Search research databases ;  you can find recommended databases for your subject area in  research by subject  for your course or program.

Identifying Gaps

If you do not find articles in your literature search, this may indicate a gap.

If you do find articles, the goal is to find a gap for contributing new research. Authors signal that there is a gap using words such as:

  • Has not been clarified, studied, reported, or elucidated
  • Further research is required or needed
  • Is not well reported
  • Suggestions for further research
  • Key question is or remains
  • It is important to address
  • Poorly understood or known
  • Lack of studies
  • These findings provide valuable insights into the potential benefits of mindfulness-based interventions for stress management,however, further study is needed to address several limitations and extend our understanding in this area .
  • While this study provides preliminary evidence of the potential efficacy of VRET in reducing PTSD symptoms, several aspects related to its implementation and specific treatment outcomes  remain inadequately clarified, highlighting the need for further research .
  • Although the studies reviewed provide valuable insights into the potential effects of climate change on species composition and ecosystem functioning.  The question of how climate change will interact with other anthropogenic stressors to influence the resilience and adaptive capacity of tropical rainforest ecosystems remains unanswered, highlighting the need for further research .

What is a research gap.

A research gap is a question or a problem that has not been answered by any of the existing studies or research within your field. Sometimes, a research gap exists when there is a concept or new idea that hasn't been studied at all. Sometimes you'll find a research gap if all the existing research is outdated and in need of new/updated research (studies on Internet use in 2001, for example). Or, perhaps a specific population has not been well studied (perhaps there are plenty of studies on teenagers and video games, but not enough studies on toddlers and video games, for example). These are just a few examples, but any research gap you find is an area where more studies and more research need to be conducted. Please view this video clip from our Sage Research Methods database for more helpful information: How Do You Identify Gaps in Literature?

How do I find one?

It will take a lot of research and reading.  You'll need to be very familiar with all the studies that have already been done, and what those studies contributed to the overall body of knowledge about that topic. Make a list of any questions you have about your topic and then do some research to see if those questions have already been answered satisfactorily. If they haven't, perhaps you've discovered a gap!  Here are some strategies you can use to make the most of your time:

  • One useful trick is to look at the “suggestions for future research” or conclusion section of existing studies on your topic. Many times, the authors will identify areas where they think a research gap exists, and what studies they think need to be done in the future.
  • As you are researching, you will most likely come across citations for seminal works in your research field. These are the research studies that you see mentioned again and again in the literature.  In addition to finding those and reading them, you can use a database like Web of Science to follow the research trail and discover all the other articles that have cited these. See the FAQ: I found the perfect article for my paper. How do I find other articles and books that have cited it? on how to do this. One way to quickly track down these seminal works is to use a database like SAGE Navigator, a social sciences literature review tool. It is one of the products available via our SAGE Knowledge database.
  • In the PsycINFO and PsycARTICLES databases, you can select literature review, systematic review, and meta analysis under the Methodology section in the advanced search to quickly locate these. See the FAQ: Where can I find a qualitative or quantitative study? for more information on how to find the Methodology section in these two databases.
  • In CINAHL , you can select Systematic review under the Publication Type field in the advanced search. 
  • In Web of Science , check the box beside Review under the Document Type heading in the “Refine Results” sidebar to the right of the list of search hits.
  • If the database you are searching does not offer a way to filter your results by document type, publication type, or methodology in the advanced search, you can include these phrases (“literature reviews,” meta-analyses, or “systematic reviews”) in your search string.  For example, “video games” AND “literature reviews” could be a possible search that you could try.

Please give these suggestions a try and contact a librarian for additional assistance.

Identifying Research Gaps to Pursue Innovative Research

' src=

This article is an excerpt from a lecture given by my Ph.D. guide, a researcher in public health. She advised us on how to identify research gaps to pursue innovative research in our fields.

What is a Research Gap?

Today we are talking about the research gap: what is it, how to identify it, and how to make use of it so that you can pursue innovative research. Now, how many of you have ever felt you had discovered a new and exciting research question , only to find that it had already been written about? I have experienced this more times than I can count. Graduate studies come with pressure to add new knowledge to the field. We can contribute to the progress and knowledge of humanity. To do this, we need to first learn to identify research gaps in the existing literature.

A research gap is, simply, a topic or area for which missing or insufficient information limits the ability to reach a conclusion for a question. It should not be confused with a research question, however. For example, if we ask the research question of what the healthiest diet for humans is, we would find many studies and possible answers to this question. On the other hand, if we were to ask the research question of what are the effects of antidepressants on pregnant women, we would not find much-existing data. This is a research gap. When we identify a research gap, we identify a direction for potentially new and exciting research.

peer review

How to Identify Research Gap?

Considering the volume of existing research, identifying research gaps can seem overwhelming or even impossible. I don’t have time to read every paper published on public health. Similarly, you guys don’t have time to read every paper. So how can you identify a research gap?

There are different techniques in various disciplines, but we can reduce most of them down to a few steps, which are:

  • Identify your key motivating issue/question
  • Identify key terms associated with this issue
  • Review the literature, searching for these key terms and identifying relevant publications
  • Review the literature cited by the key publications which you located in the above step
  • Identify issues not addressed by  the literature relating to your critical  motivating issue

It is the last step which we all find the most challenging. It can be difficult to figure out what an article is  not  saying. I like to keep a list of notes of biased or inconsistent information. You could also track what authors write as “directions for future research,” which often can point us towards the existing gaps.

Different Types of Research Gaps

Identifying research gaps is an essential step in conducting research, as it helps researchers to refine their research questions and to focus their research efforts on areas where there is a need for more knowledge or understanding.

1. Knowledge gaps

These are gaps in knowledge or understanding of a subject, where more research is needed to fill the gaps. For example, there may be a lack of understanding of the mechanisms behind a particular disease or how a specific technology works.

2. Conceptual gaps

These are gaps in the conceptual framework or theoretical understanding of a subject. For example, there may be a need for more research to understand the relationship between two concepts or to refine a theoretical framework.

3. Methodological gaps

These are gaps in the methods used to study a particular subject. For example, there may be a need for more research to develop new research methods or to refine existing methods to address specific research questions.

4. Data gaps

These are gaps in the data available on a particular subject. For example, there may be a need for more research to collect data on a specific population or to develop new measures to collect data on a particular construct.

5. Practical gaps

These are gaps in the application of research findings to practical situations. For example, there may be a need for more research to understand how to implement evidence-based practices in real-world settings or to identify barriers to implementing such practices.

Examples of Research Gap

Limited understanding of the underlying mechanisms of a disease:.

Despite significant research on a particular disease, there may be a lack of understanding of the underlying mechanisms of the disease. For example, although much research has been done on Alzheimer’s disease, the exact mechanisms that lead to the disease are not yet fully understood.

Inconsistencies in the findings of previous research:

When previous research on a particular topic has inconsistent findings, there may be a need for further research to clarify or resolve these inconsistencies. For example, previous research on the effectiveness of a particular treatment for a medical condition may have produced inconsistent findings, indicating a need for further research to determine the true effectiveness of the treatment.

Limited research on emerging technologies:

As new technologies emerge, there may be limited research on their applications, benefits, and potential drawbacks. For example, with the increasing use of artificial intelligence in various industries, there is a need for further research on the ethical, legal, and social implications of AI.

How to Deal with Literature Gap?

Once you have identified the literature gaps, it is critical to prioritize. You may find many questions which remain to be answered in the literature. Often one question must be answered before the next can be addressed. In prioritizing the gaps, you have identified, you should consider your funding agency or stakeholders, the needs of the field, and the relevance of your questions to what is currently being studied. Also, consider your own resources and ability to conduct the research you’re considering. Once you have done this, you can narrow your search down to an appropriate question.

Tools to Help Your Search

There are thousands of new articles published every day, and staying up to date on the literature can be overwhelming. You should take advantage of the technology that is available. Some services include  PubCrawler ,  Feedly ,  Google Scholar , and PubMed updates. Stay up to date on social media forums where scholars share new discoveries, such as Twitter. Reference managers such as  Mendeley  can help you keep your references well-organized. I personally have had success using Google Scholar and PubMed to stay current on new developments and track which gaps remain in my personal areas of interest.

The most important thing I want to impress upon you today is that you will struggle to  choose a research topic  that is innovative and exciting if you don’t know the existing literature well. This is why identifying research gaps starts with an extensive and thorough  literature review . But give yourself some boundaries.  You don’t need to read every paper that has ever been written on a topic. You may find yourself thinking you’re on the right track and then suddenly coming across a paper that you had intended to write! It happens to everyone- it happens to me quite often. Don’t give up- keep reading and you’ll find what you’re looking for.

What is the research gap in literature review?

  • The purpose of a literature review is not only to examine the past available literature but also identifying gaps in the literature.
  • According to Robinson et al., a research gap arises ‘when the capability of the reviewer to draw conclusions from existing studies is limited.’ A research gap forms a starting point for conducting further research.
  • While a research gap in literature review can be considered an ‘output’ of a literature review, it can also be considered an ‘input’ that motivates further research (Bloch, 2015).

Types of research gaps

Research gaps can also arise due to contradictory findings, changing trends and unanswered questions. Classification of research gaps facilitates convenience and can be classified as follows:-

1.Theoretical gap: A gap in existing theories and models in the field that has not been effectively addressed is known as a theoretical gap or theory application void gap.

It can be identified through a literature review, where the researcher examines the existing literature on the research topic and identifies inconsistencies, limitations, and gaps in the research.

Example: In economics and finance , a theoretical gap arises when there is a lack of understanding of the factors that lead to financial bubbles, characterised by periods of a stark increase in prices followed by a decline.

2.Empirical gap: The term “empirical gap” refers to the missing or undiscovered components of a phenomenon that can be addressed through empirical research. When the available data or empirical research is unable to answer specific research questions, a gap results, known as an empirical gap or empirical void gap.

For instance, a study conducted by Goh and Lee (2020) on the impact of social media on consumer behaviour found that there is a lack of research on the role of social media influencers in shaping consumer behaviour for availing services and purchasing products. This can be considered an empirical gap that can be addressed through new empirical research.

An example of an empirical gap is understanding the environmental, social and governance (ESG) factors and financial performance. Some studies reveal a positive connection between strong ESG practices and financial performance, whereas others find no or even a negative association.

3.Methodological gap: A methodological gap, or method and research design gap, is a gap in the research procedures and techniques employed in previous studies that may affect the precision and reliability of the findings. This can impair the accuracy of analysis, limit the scope of research, and hinder the development of robust models or solutions in the field of finance.

Sometimes, researchers conducting research in finance may lack the necessary data, leading to methodological research gaps. Limited data hinders the ability to conduct further research, leading to a methodological gap.

4.Practical gap: Practical gap arises when there is a discrepancy between theory and practice, where there is a necessity to conduct further research to address this gap and improve the application of the theoretical findings into practice. A practical gap is also called Practical-Knowledge Gap or Action-Knowledge-Conflict Gap.

An example of a practical gap in finance is the access and utilisation of financial education programs, workshops and online resources that can help individuals to gain and apply knowledge to manage their finances effectively. This gap occurs since financial literacy varies between populations.

5.Conceptual gap: Conceptual gaps occur when there is inconsistency or ambiguity in a concept’s definition, interpretation, or application, resulting in confusion and misunderstanding. Conceptual gaps lead to inconsistent or unclear definitions and interpretations.

For instance, there is a conceptual gap in building frameworks that explicitly recognise the crucial role of managing stakeholders and creating value for long-term financial performance and sustainable growth.

Another example of a conceptual gap is the f uture applications of financial instruments , where the definition of financial instruments was not clear till Brown gave one for understanding .    

6.Knowledge gap: A knowledge gap is the difference between what is known and what needs to be known about a specific topic. A knowledge gap can occur for various reasons, including insufficient or incomplete information, contradictory information, limited research, and outdated information.

To identify a knowledge gap, researchers must extensively examine the available literature and identify areas where additional study is required. They can also conduct surveys or interviews to examine the general public’s or specialists’ knowledge and awareness of a specific problem. Addressing a knowledge gap leads to advancing knowledge in a particular field and gives rise to new concepts, theories or practices.

An example of a knowledge gap is the effect of emerging financial technologies on traditional banking systems. There is a greater risk for cybersecurity, like identity theft, data breaches and cyber threats, and researchers can study the risks of financial technologies and offer management strategies for customers and financial institutions (Kavuri, 2019).

A research gap occurs when a researcher is unable to draw conclusions from existing literature. Identifying gaps in literature is crucial for a literature review. There are various types of research gaps that include theoretical gas, empirical gaps, methodological gaps, practical gaps, conceptual gaps and knowledge gaps. Addressing these types of research gaps can significantly add to the existing body of knowledge and lead to knowledge advancement in a given field.
