Research Gap

Definition:

Research gap refers to an area or topic within a field of study that has not yet been extensively researched or is yet to be explored. It is a question, problem or issue that has not been addressed or resolved by previous research.

How to Identify Research Gap

Identifying a research gap is an essential step in conducting research that adds value and contributes to the existing body of knowledge. Research gap requires critical thinking, creativity, and a thorough understanding of the existing literature . It is an iterative process that may require revisiting and refining your research questions and ideas multiple times.

Here are some steps that can help you identify a research gap:

• Review existing literature: Conduct a thorough review of the existing literature in your research area. This will help you identify what has already been studied and what gaps still exist.
• Identify a research problem: Identify a specific research problem or question that you want to address.
• Analyze existing research: Analyze the existing research related to your research problem. This will help you identify areas that have not been studied, inconsistencies in the findings, or limitations of the previous research.
• Brainstorm potential research ideas : Based on your analysis, brainstorm potential research ideas that address the identified gaps.
• Consult with experts: Consult with experts in your research area to get their opinions on potential research ideas and to identify any additional gaps that you may have missed.
• Refine research questions: Refine your research questions and hypotheses based on the identified gaps and potential research ideas.
• Develop a research proposal: Develop a research proposal that outlines your research questions, objectives, and methods to address the identified research gap.

Types of Research Gap

There are different types of research gaps that can be identified, and each type is associated with a specific situation or problem. Here are the main types of research gaps and their explanations:

Theoretical Gap

This type of research gap refers to a lack of theoretical understanding or knowledge in a particular area. It can occur when there is a discrepancy between existing theories and empirical evidence or when there is no theory that can explain a particular phenomenon. Identifying theoretical gaps can lead to the development of new theories or the refinement of existing ones.

Empirical Gap

An empirical gap occurs when there is a lack of empirical evidence or data in a particular area. It can happen when there is a lack of research on a specific topic or when existing research is inadequate or inconclusive. Identifying empirical gaps can lead to the development of new research studies to collect data or the refinement of existing research methods to improve the quality of data collected.

Methodological Gap

This type of research gap refers to a lack of appropriate research methods or techniques to answer a research question. It can occur when existing methods are inadequate, outdated, or inappropriate for the research question. Identifying methodological gaps can lead to the development of new research methods or the modification of existing ones to better address the research question.

Practical Gap

A practical gap occurs when there is a lack of practical applications or implementation of research findings. It can occur when research findings are not implemented due to financial, political, or social constraints. Identifying practical gaps can lead to the development of strategies for the effective implementation of research findings in practice.

Knowledge Gap

This type of research gap occurs when there is a lack of knowledge or information on a particular topic. It can happen when a new area of research is emerging, or when research is conducted in a different context or population. Identifying knowledge gaps can lead to the development of new research studies or the extension of existing research to fill the gap.

Examples of Research Gap

Here are some examples of research gaps that researchers might identify:

• Theoretical Gap Example : In the field of psychology, there might be a theoretical gap related to the lack of understanding of the relationship between social media use and mental health. Although there is existing research on the topic, there might be a lack of consensus on the mechanisms that link social media use to mental health outcomes.
• Empirical Gap Example : In the field of environmental science, there might be an empirical gap related to the lack of data on the long-term effects of climate change on biodiversity in specific regions. Although there might be some studies on the topic, there might be a lack of data on the long-term effects of climate change on specific species or ecosystems.
• Methodological Gap Example : In the field of education, there might be a methodological gap related to the lack of appropriate research methods to assess the impact of online learning on student outcomes. Although there might be some studies on the topic, existing research methods might not be appropriate to assess the complex relationships between online learning and student outcomes.
• Practical Gap Example: In the field of healthcare, there might be a practical gap related to the lack of effective strategies to implement evidence-based practices in clinical settings. Although there might be existing research on the effectiveness of certain practices, they might not be implemented in practice due to various barriers, such as financial constraints or lack of resources.
• Knowledge Gap Example: In the field of anthropology, there might be a knowledge gap related to the lack of understanding of the cultural practices of indigenous communities in certain regions. Although there might be some research on the topic, there might be a lack of knowledge about specific cultural practices or beliefs that are unique to those communities.

Examples of Research Gap In Literature Review, Thesis, and Research Paper might be:

• Literature review : A literature review on the topic of machine learning and healthcare might identify a research gap in the lack of studies that investigate the use of machine learning for early detection of rare diseases.
• Thesis : A thesis on the topic of cybersecurity might identify a research gap in the lack of studies that investigate the effectiveness of artificial intelligence in detecting and preventing cyber attacks.
• Research paper : A research paper on the topic of natural language processing might identify a research gap in the lack of studies that investigate the use of natural language processing techniques for sentiment analysis in non-English languages.

How to Write Research Gap

By following these steps, you can effectively write about research gaps in your paper and clearly articulate the contribution that your study will make to the existing body of knowledge.

Here are some steps to follow when writing about research gaps in your paper:

• Identify the research question : Before writing about research gaps, you need to identify your research question or problem. This will help you to understand the scope of your research and identify areas where additional research is needed.

Different Types of Research Gaps

Research gaps are areas where knowledge is lacking or where existing research could be expanded. Identifying and addressing these gaps is crucial for advancing knowledge in any field. Here are the different types of research gaps:

1. Evidence Gap

Definition : An evidence gap occurs when there is a lack of empirical data to support conclusions or theories. This gap signifies areas where more research is needed to provide solid evidence for or against a hypothesis.

Example : Limited studies on the long-term effects of a new medication.

2. Knowledge Gap

Definition : A knowledge gap refers to a lack of understanding or awareness about a specific topic. This gap often highlights areas where research has not yet been conducted or where findings are inconsistent.

Example : Insufficient knowledge about the impact of social media on mental health among teenagers.

3. Practical-Knowledge Gap

Definition : This gap arises when there is a disconnect between theoretical research and practical application. It points to areas where findings from research have not been implemented in real-world settings or where practical challenges are not addressed by existing research.

Example : Theoretical models for disaster management that are not tested in actual disaster scenarios.

4. Methodological Gap

Definition : A methodological gap is identified when current research methods are inadequate to address certain research questions. This gap indicates the need for new or improved research methods.

Example : The need for longitudinal studies to better understand the progression of chronic diseases.

5. Policy Gap

Definition : A policy gap occurs when research does not inform policy or when there is a lack of research supporting existing policies. This gap often highlights the need for research that can influence or evaluate policy decisions.

Example : Lack of research on the effectiveness of policies aimed at reducing carbon emissions.

6. Population Gap

Definition : This gap is present when certain populations or demographic groups are underrepresented in research. It calls attention to the need for more inclusive research that considers diverse populations.

Example : Underrepresentation of elderly populations in clinical trials for new medications.

7. Theory Gap

Definition : A theory gap is found when there is a lack of theoretical framework to explain certain phenomena. This gap suggests the need for developing or refining theories to better understand specific issues.

Example : Incomplete theoretical explanations for the rise of extremism in modern societies.

8. Contextual Gap

Definition : A contextual gap exists when research does not take into account the context in which a phenomenon occurs. This gap highlights the need for studies that consider environmental, cultural, or situational factors.

Example : Studies on education methods that do not consider cultural differences in learning styles.

9. Perspective Gap

Definition : This gap arises when certain perspectives or viewpoints are missing from the research. It emphasizes the need for more diverse viewpoints to provide a comprehensive understanding of a topic.

Example : Limited perspectives from minority groups in research on workplace diversity.

10. Data Gap

Definition : A data gap is identified when there is a lack of available data or when existing data is insufficient to support research conclusions. This gap indicates the need for more extensive data collection and analysis.

Example : Insufficient data on climate change impacts in specific geographic regions.

How To Find A Research Gap, Quickly

By: Derek Jansen (MBA) | Reviewer: Eunice Rautenbach (DTech) | April 2023

Overview: Finding Research Gaps

• What exactly is a research gap?
• Research gap vs research topic
• How to find potential research gaps
• How to evaluate research gaps (and topics)
• Key takeaways

What is a research gap?

As a starting point, it’s useful to first define what we mean by research gap, to ensure we’re all on the same page. The term “research gap” gets thrown around quite loosely by students and academics alike, so let’s clear that up.

Simply put, a research gap is any space where there’s a lack of solid, agreed-upon research regarding a specific topic, issue or phenomenon. In other words, there’s a lack of established knowledge and, consequently, a need for further research.

Let’s look at a hypothetical example to illustrate a research gap.

Within the existing research regarding factors affect job satisfaction , there may be a wealth of established and agreed-upon empirical work within a US and UK context , but very little research within Eastern nations such as Japan or Korea . Given that these nations have distinctly different national cultures and workforce compositions compared to the West, it’s plausible that the factors that contribute toward job satisfaction may also be different. Therefore, a research gap emerges for studies that explore this matter.

This example is purely hypothetical (and there’s probably plenty of research covering this already), but it illustrates the core point that a research gap reflects a lack of firmly established knowledge regarding a specific matter . Given this lack, an opportunity exists for researchers (like you) to go on and fill the gap.

So, it’s the same as a research topic?

Not quite – but they are connected. A research gap refers to an area where there’s a lack of settled research , whereas a research topic outlines the focus of a specific study . Despite being different things, these two are related because research gaps are the birthplace of research topics. In other words, by identifying a clear research gap, you have a foundation from which you can build a research topic for your specific study. Your study is unlikely to resolve the entire research gap on it’s own, but it will contribute towards it .

If you’d like to learn more, we’ve got a comprehensive post that covers research gaps (including the different types of research gaps), as well as an explainer video below.

How to find a research gap

Now that we’ve defined what a research gap is, it’s time to get down to the process of finding potential research gaps that you can use as a basis for potential research topics. Importantly, it’s worth noting that this is just one way (of many) to find a research gap (and consequently a topic). We’re not proposing that it’s the only way or best way, but it’s certainly a relatively quick way to identify opportunities.

Step 1: Identify your broad area of interest

The very first step to finding a research gap is to decide on your general area of interest . For example, if you were undertaking a dissertation as part of an MBA degree, you may decide that you’re interested in corporate reputation, HR strategy, or leadership styles. As you can see, these are broad categories – there’s no need to get super specific just yet. Of course, if there is something very specific that you’re interested in, that’s great – but don’t feel pressured to narrow it down too much right now.

Equally important is to make sure that this area of interest is allowed by your university or whichever institution you’ll be proposing your research to. This might sound dead obvious, but you’ll be surprised how many times we’ve seen students run down a path with great excitement, only to later learn that their university wants a very specific area of focus in terms of topic (and their area of interest doesn’t qualify).

Step 2: Do an initial literature scan

Once you’ve pinned down your broad area (or areas) of interest, the next step is to head over to Google Scholar to undertake an initial literature scan . If you’re not familiar with this tool, Google Scholar is a great starting point for finding academic literature on pretty much any topic, as it uses Google’s powerful search capabilities to hunt down relevant academic literature. It’s certainly not the be-all and end-all of literature search tools, but it’s a useful starting point .

Within Google Scholar, you’ll want to do a few searches using keywords that are relevant to your area of interest. Sticking with our earlier example, we could use the key phrase “job satisfaction”, or we may want to get a little more specific – perhaps “job satisfaction for millennials” or “job satisfaction in Japan”.

It’s always a good idea to play around with as many keywords/phrases as you can think up.  Take an iterative approach here and see which keywords yield the most relevant results for you. Keep each search open in a new tab, as this will help keep things organised for the next steps.

Once you’ve searched for a few different keywords/phrases, you’ll need to do some refining for each of the searches you undertook. Specifically, you’ll need to filter the results down to the most recent papers . You can do this by selecting the time period in the top left corner (see the example below).

Filtering to the current year is typically a good choice (especially for fast-moving research areas), but in some cases, you may need to filter to the last two years . If you’re undertaking this task in January or February, for example, you’ll likely need to select a two-year period.

Step 3: Review and shortlist articles that interest you

Once you’ve run a few searches using different keywords and phrases, you’ll need to scan through the results to see what looks most relevant and interesting to you. At this stage, you can just look at the titles and abstracts (the description provided by Google Scholar) – don’t worry about reading the actual article just yet.

Next, select 5 – 10 articles that interest you and open them up. Here, we’re making the assumption that your university has provided you with access to a decent range of academic databases. In some cases, Google Scholar will link you directly to a PDF of the article, but in most cases, you’ll need paid access. If you don’t have this (for example, if you’re still applying to a university), you can look at two options:

Open-access articles – these are free articles which you can access without any journal subscription. A quick Google search (the regular Google) will help you find open-access journals in your area of interest, but you can also have a look at DOAJ and Elsevier Open Access.

DeepDyve – this is a monthly subscription service that allows you to get access to a broad range of journals. At the time of shooting this video, their monthly subscription is around $50 and they do offer a free trial, which may be sufficient for your project.

Step 4: Skim-read your article shortlist

Now, it’s time to dig into your article shortlist and do some reading. But don’t worry, you don’t need to read the articles from start to finish – you just need to focus on a few key sections.

Specifically, you’ll need to pay attention to the following:

• The abstract (which you’ve probably already read a portion of in Google Scholar)
• The introduction – this will give you a bit more detail about the context and background of the study, as well as what the researchers were trying to achieve (their research aims)
• The discussion or conclusion – this will tell you what the researchers found

By skimming through these three sections for each journal article on your shortlist, you’ll gain a reasonable idea of what each study was about, without having to dig into the painful details. Generally, these sections are usually quite short, so it shouldn’t take you too long.

Step 5: Go “FRIN hunting”

This is where the magic happens. Within each of the articles on your shortlist, you’ll want to search for a few very specific phrases , namely:

• Future research
• Further research
• Research opportunities
• Research directions

All of these terms are commonly found in what we call the “FRIN” section . FRIN stands for “further research is needed”. The FRIN is where the researchers explain what other researchers could do to build on their study, or just on the research area in general. In other words, the FRIN section is where you can find fresh opportunities for novel research . Most empirical studies will either have a dedicated FRIN section or paragraph, or they’ll allude to the FRIN toward the very end of the article. You’ll need to do a little scanning, but it’s usually pretty easy to spot.

It’s worth mentioning that naturally, the FRIN doesn’t hand you a list of research gaps on a platter. It’s not a silver bullet for finding research gaps – but it’s the closest thing to it. Realistically, the FRIN section helps you shortcut the gap-hunting process  by highlighting novel research avenues that are worth exploring.

This probably sounds a little conceptual, so let’s have a look at a few examples:

The impact of overeducation on job outcomes: Evidence from Saudi Arabia (Alzubaidi, 2020)

If you scroll down to the bottom of this article, you’ll see there’s a dedicated section called “Limitations and directions for future research”. Here they talk about the limitations of the study and provide suggestions about how future researchers could improve upon their work and overcome the limitations.

Perceived organizational support and job satisfaction: a moderated mediation model of proactive personality and psychological empowerment (Maan et al, 2020)

In this article, within the limitations section, they provide a wonderfully systematic structure where they discuss each limitation, followed by a proposal as to how future studies can overcome the respective limitation. In doing so, they are providing very specific research opportunities for other researchers.

Medical professionals’ job satisfaction and telemedicine readiness during the COVID-19 pandemic: solutions to improve medical practice in Egypt (El-Mazahy et al, 2023)

In this article, they don’t have a dedicated section discussing the FRIN, but we can deduct it based on the limitations section. For example, they state that an evaluation of the knowledge about telemedicine and technology-related skills would have enabled studying their independent effect on the perception of telemedicine.

Follow this FRIN-seeking process for the articles you shortlisted and map out any potentially interesting research gaps . You may find that you need to look at a larger number of articles to find something interesting, or you might find that your area of interest shifts as you engage in the reading – this is perfectly natural. Take as much time as you need to develop a shortlist of potential research gaps that interest you.

Importantly, once you’ve developed a shortlist of potential research gaps, you need to return to Google Scholar to double-check that there aren’t fresh studies that have already addressed the gap. Remember, if you’re looking at papers from two years ago in a fast-moving field, someone else may have jumped on it . Nevertheless, there could still very well be a unique angle you could take – perhaps a contextual gap (e.g. a specific country, industry, etc.).

Ultimately, the need for originality will depend on your specific university’s requirements and the level of study. For example, if you’re doing an undergraduate research project, the originality requirements likely won’t be as gruelling as say a Masters or PhD project. So, make sure you have a clear understanding of what your university’s expectations are. A good way to do this is to look at past dissertations and theses for your specific programme. You can usually find these in the university library or by asking the faculty.

How to evaluate potential research gaps

Once you’ve developed a shortlist of potential research gaps (and resultant potential research topics) that interest you, you’ll need to systematically evaluate  them  to choose a winner. There are many factors to consider here, but some important ones include the following:

• Originality and value – is the topic sufficiently novel and will addressing it create value?
• Data access – will you be able to get access to the sample of interest?
• Costs – will there be additional costs involved for data collection and/or analysis?
• Timeframes – will you be able to collect and analyse the data within the timeframe required by your university?
• Supervisor support – is there a suitable supervisor available to support your project from start to finish?

To help you evaluate your options systematically, we’ve got a topic evaluation worksheet that allows you to score each potential topic against a comprehensive set of criteria. You can access the worksheet completely free of charge here .

Recap: Key Takeaways

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

• A research gap is any space where there’s a lack of solid, agreed-upon research regarding a specific topic/issue/phenomenon.
• Unique research topics emerge from research gaps , so it’s essential to first identify high-quality research gaps before you attempt to define a topic.

A Guide to Scientific Communication

Gap Statements

  A gap is something that remains to be done or learned in an area of research; it’s a gap in the knowledge of the scientists in the field of research of your study. Every research project must, in some way, address a gap–that is, attempt to fill in some piece of information missing in the scientific literature. Otherwise, it is not novel research and is therefore not contributing to the overall goals of science.

Identify the gap.

  A gap statement is found in the Introduction section of a journal article or poster or in the Goals and Importance section of a research proposal and succinctly identifies for your audience the gap that you will attempt to address in your project.

A gap might be a lack of understanding about how well a particular instrument works in a certain situation. It could be introducing a new method that needs to be tested. Or it could be that you are studying a whole new organism, system, or part of a process. Your project may also address multiple gaps, in which case you should be sure to identify each of them clearly!

In a class, you might not always be studying something brand “new.” But, in most cases, you should still try to come up with something unique about your project, however small. Talk to your professor about what they expect for your gap statement if nothing seems to work.

Here, the authors signal to us that this is a gap because they use the words “has not yet been clarified.” Other phrases that might help you identify (or form!) a gap statement are:

• …has/have not been… (studied/reported/elucidated)
• …is required/needed…
• …the key question is/remains…
• …it is important to address…

Fill the gap.

  Once you identify the gap in the literature, you must tell your audience how you attempt to at least somewhat address in your project this lack of knowledge or understanding . In a journal article or poster, this is often done in a new paragraph and should be accomplished in one summary statement, such as:

Therefore, the purpose of this study was to determine the effects of lead on the hepatobiliary system, especially on the liver and on the gallbladder (adapted from Sipos et al. 2003 ).

You’ll often find that the first sentence of the last paragraph in a paper’s introduction will start somewhat like this, indicating the gap fill.  

Remember–always keep your voice professional! Colloquial phrases such as “we looked into” or “we checked if” should be avoided when introducing your gap fill.

So let’s look at this idea in context by looking at some examples from a couple of types of papers. The gap statements are underlined; the fills are italicized.  

In the second and third examples, the gap may be a little less obvious–it doesn’t use any phrases to signal to you that there’s something missing, such as “has not been clarified” or “have not been reported.” But because of the way the paragraph is laid out–following the conventions of our move structures–we can see that the underlined section of text is indeed the missing information in the literature that the group sought to address in their project.

How to Identify a Research Gap

5-minute read

• 10th January 2024

If you’ve been tasked with producing a thesis or dissertation, one of your first steps will be identifying a research gap. Although finding a research gap may sound daunting, don’t fret! In this post, we will define a research gap, discuss its importance, and offer a step-by-step guide that will provide you with the essential know-how to complete this critical step and move on to the rest of your research project.

What Is a Research Gap?

Simply put, a research gap is an area that hasn’t been explored in the existing literature. This could be an unexplored population, an untested method, or a condition that hasn’t been investigated yet. 

Why Is Identifying a Research Gap Important?

Identifying a research gap is a foundational step in the research process. It ensures that your research is significant and has the ability to advance knowledge within a specific area. It also helps you align your work with the current needs and challenges of your field. Identifying a research gap has many potential benefits.

1. Avoid Redundancy in Your Research

Understanding the existing literature helps researchers avoid duplication. This means you can steer clear of topics that have already been extensively studied. This ensures your work is novel and contributes something new to the field.

2. Guide the Research Design

Identifying a research gap helps shape your research design and questions. You can tailor your studies to specifically address the identified gap. This ensures that your work directly contributes to filling the void in knowledge.

3. Practical Applications

Research that addresses a gap is more likely to have practical applications and contributions. Whether in academia, industry, or policymaking, research that fills a gap in knowledge is often more applicable and can inform decision-making and practices in real-world contexts.

4. Field Advancements

Addressing a research gap can lead to advancements in the field . It may result in the development of new theories, methodologies, or technologies that push the boundaries of current understanding.

5. Strategic Research Planning

Identifying a research gap is crucial for strategic planning . It helps researchers and institutions prioritize areas that need attention so they can allocate resources effectively. This ensures that efforts are directed toward the most critical gaps in knowledge.

6. Academic and Professional Recognition

Researchers who successfully address significant research gaps often receive peer recognition within their academic and professional communities. This recognition can lead to opportunities for collaboration, funding, and career advancement.

How Do I Identify a Research Gap?

1. clearly define your research topic .

Begin by clearly defining your research topic. A well-scoped topic serves as the foundation for your studies. Make sure it’s not too broad or too narrow; striking the right balance will make it easier to identify gaps in existing literature.

2. Conduct a Thorough Literature Review

A comprehensive literature review is a vital step in any research. Dive deep into the existing research related to your topic. Look for patterns, recurring themes, and consensus among scholars. Pay attention to areas where conflicting opinions or gaps in understanding emerge.

3. Evaluate Existing Studies

Critically evaluate the studies you encounter during your literature review. Assess the paradigms , methodologies, findings, and limitations of each. Note any discrepancies, unanswered questions, or areas where further investigation is warranted. These are potential indicators of research gaps.

4. Identify Unexplored Perspectives

Consider the perspectives presented in the existing literature. Are there alternative viewpoints or marginalized voices that haven’t been adequately explored? Identifying and incorporating diverse perspectives can often lead to uncharted territory and help you pinpoint a unique research gap.

Additional Tips

Stay up to date with emerging trends.

The field of research is dynamic, with new developments and emerging trends constantly shaping the landscape. Stay up to date with the latest publications, conferences, and discussions in your field and make sure to regularly check relevant academic search engines . Often, identifying a research gap involves being at the forefront of current debates and discussions.

Seek Guidance From Experts

Don’t hesitate to reach out to experts in your field for guidance. Attend conferences, workshops, or seminars where you can interact with seasoned researchers. Their insights and experience can provide valuable perspectives on potential research gaps that you may have overlooked. You can also seek advice from your academic advisor .

Use Research Tools and Analytics

Leverage tech tools to analyze patterns and trends in the existing literature. Tools like citation analysis, keyword mapping, and data visualization can help you identify gaps and areas with limited exploration.

Identifying a research gap is a skill that evolves with experience and dedication. By defining your research topic, meticulously navigating the existing literature, critically evaluating studies, and recognizing unexplored perspectives, you’ll be on your way to identifying a research gap that will serve as the foundation for your paper, thesis, or dissertation topic .
