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.
• Review the literature: Conduct a thorough review of the literature related to your research question. This will help you to identify the current state of knowledge in the field and the gaps that exist.
• Identify the research gap: Based on your review of the literature, identify the specific research gap that your study will address. This could be a theoretical, empirical, methodological, practical, or knowledge gap.
• Provide evidence: Provide evidence to support your claim that the research gap exists. This could include a summary of the existing literature, a discussion of the limitations of previous studies, or an analysis of the current state of knowledge in the field.
• Explain the importance: Explain why it is important to fill the research gap. This could include a discussion of the potential implications of filling the gap, the significance of the research for the field, or the potential benefits to society.
• State your research objectives: State your research objectives, which should be aligned with the research gap you have identified. This will help you to clearly articulate the purpose of your study and how it will address the research gap.

Importance of Research Gap

The importance of research gaps can be summarized as follows:

• Advancing knowledge: Identifying research gaps is crucial for advancing knowledge in a particular field. By identifying areas where additional research is needed, researchers can fill gaps in the existing body of knowledge and contribute to the development of new theories and practices.
• Guiding research: Research gaps can guide researchers in designing studies that fill those gaps. By identifying research gaps, researchers can develop research questions and objectives that are aligned with the needs of the field and contribute to the development of new knowledge.
• Enhancing research quality: By identifying research gaps, researchers can avoid duplicating previous research and instead focus on developing innovative research that fills gaps in the existing body of knowledge. This can lead to more impactful research and higher-quality research outputs.
• Informing policy and practice: Research gaps can inform policy and practice by highlighting areas where additional research is needed to inform decision-making. By filling research gaps, researchers can provide evidence-based recommendations that have the potential to improve policy and practice in a particular field.

Applications of Research Gap

Here are some potential applications of research gap:

• Informing research priorities: Research gaps can help guide research funding agencies and researchers to prioritize research areas that require more attention and resources.
• Identifying practical implications: Identifying gaps in knowledge can help identify practical applications of research that are still unexplored or underdeveloped.
• Stimulating innovation: Research gaps can encourage innovation and the development of new approaches or methodologies to address unexplored areas.
• Improving policy-making: Research gaps can inform policy-making decisions by highlighting areas where more research is needed to make informed policy decisions.
• Enhancing academic discourse: Research gaps can lead to new and constructive debates and discussions within academic communities, leading to more robust and comprehensive research.

Advantages of Research Gap

Here are some of the advantages of research gap:

• Identifies new research opportunities: Identifying research gaps can help researchers identify areas that require further exploration, which can lead to new research opportunities.
• Improves the quality of research: By identifying gaps in current research, researchers can focus their efforts on addressing unanswered questions, which can improve the overall quality of research.
• Enhances the relevance of research: Research that addresses existing gaps can have significant implications for the development of theories, policies, and practices, and can therefore increase the relevance and impact of research.
• Helps avoid duplication of effort: Identifying existing research can help researchers avoid duplicating efforts, saving time and resources.
• Helps to refine research questions: Research gaps can help researchers refine their research questions, making them more focused and relevant to the needs of the field.
• Promotes collaboration: By identifying areas of research that require further investigation, researchers can collaborate with others to conduct research that addresses these gaps, which can lead to more comprehensive and impactful research outcomes.

Disadvantages of Research Gap

While research gaps can be advantageous, there are also some potential disadvantages that should be considered:

• Difficulty in identifying gaps: Identifying gaps in existing research can be challenging, particularly in fields where there is a large volume of research or where research findings are scattered across different disciplines.
• Lack of funding: Addressing research gaps may require significant resources, and researchers may struggle to secure funding for their work if it is perceived as too risky or uncertain.
• Time-consuming: Conducting research to address gaps can be time-consuming, particularly if the research involves collecting new data or developing new methods.
• Risk of oversimplification: Addressing research gaps may require researchers to simplify complex problems, which can lead to oversimplification and a failure to capture the complexity of the issues.
• Bias : Identifying research gaps can be influenced by researchers’ personal biases or perspectives, which can lead to a skewed understanding of the field.
• Potential for disagreement: Identifying research gaps can be subjective, and different researchers may have different views on what constitutes a gap in the field, leading to disagreements and debate.

How To Find A Research Gap, Quickly

A step-by-step guide for new researchers

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

If you’ve got a dissertation, thesis or research project coming up, one of the first (and most important) things you’ll need to do is find a suitable research gap . In this post, we’ll share a straightforward process to help you uncover high-quality, original research gaps in a very time-efficient manner.

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.
• To find potential research gaps, start by seeking out recent journal articles on Google Scholar and pay particular attention to the FRIN section to identify novel opportunities.
• Once you have a shortlist of prospective research gaps and resultant topic ideas, evaluate them systematically using a comprehensive set of criteria.

Identifying Research Gaps to Pursue Innovative Research

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.

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.

Class dismissed!

The Best Method In Identifying Research Gap: An In-depth Analysis

What is research gap.

A research gap refers to an area or topic that has not been sufficiently explored or studied, leaving unanswered questions or unresolved issues. This article will provide an overview of the research gaps concept and their significance in the research process. It will also discuss the importance of identifying research gaps and how they can be used to formulate research objectives and problem statements. Additionally, this section will explore various techniques and strategies for conducting research gap analysis and bridging the gap between existing knowledge and future research endeavors.

Background of Research Gap

In the world of research, identifying and addressing research gaps is a crucial step towards advancing knowledge and understanding in a particular field. A research gap refers to an area in the existing body of knowledge where there is a lack of research or unanswered questions. In other words, it is a gap in the literature that needs to be addressed through further research.

Research gaps can occur for various reasons, such as a lack of studies on a specific topic, contradictory findings in existing research, or the emergence of new ideas or concepts that have not been explored. Identifying research gaps is crucial for the advancement of knowledge and the development of new research questions. By filling these gaps, researchers can contribute to the existing body of knowledge and address unanswered questions.

Furthermore, research gaps provide opportunities for researchers to make significant contributions to their field by conducting innovative and impactful studies. Understanding the background of research gaps is essential for researchers to identify areas where their research can make a meaningful impact.

Significance of Research Gap

The research gap plays a crucial role in the field of academia and scientific research. It holds significant importance for researchers, scholars, and the overall advancement of knowledge.

Contributing to Knowledge and Developing New Theories

One of the primary reasons why the research gap is significant is that it identifies areas where there is a lack of knowledge or understanding. It highlights the gaps in existing research, indicating the need for further investigation and exploration. By identifying research gaps, researchers can contribute to the existing body of knowledge by filling in the missing pieces. This leads to the development of new theories, concepts, and insights that can enhance our understanding of a particular subject or field.

Fostering Innovation and Progress through Unexplored Areas

Furthermore, the significance of research gaps lies in their potential to drive innovation and progress. When researchers identify areas that have not been extensively studied, they have the opportunity to explore new ideas, methodologies, and approaches. This can lead to groundbreaking discoveries and advancements in various disciplines.

Efficient Utilization of Resources to Avoid Duplication

Moreover, research gaps also help in avoiding duplication of efforts. By identifying what has already been studied and what areas are yet to be explored, researchers can focus their efforts on addressing the gaps rather than repeating existing research. This ensures that resources are utilized effectively and efficiently.

Impacting Practical Applications and Real-World Solutions

Additionally, the significance of research gaps extends to the practical application of research findings. By addressing the gaps in existing knowledge, researchers can provide valuable insights and solutions to real-world problems. This can have a direct impact on industries, policy-making, and decision-making processes. In conclusion, the significance of research gaps cannot be overstated. They serve as catalysts for knowledge advancement, innovation, and practical application. By identifying and addressing these gaps, researchers contribute to the growth and development of their respective fields, ultimately benefiting society as a whole.

Research Gap Examples

Identifying research gaps is crucial for pursuing innovative research. There are various types of research gaps that can be found in existing literature.

Knowledge gaps

Sometimes, a research gap exists when there is a concept or new idea that hasn’t been studied at all. For example, in the field of psychology, there might be a lack of research on the effects of social media on mental health in adolescents.

Conceptual gaps

Conceptual gaps occur when there is a lack of understanding or clarity about a particular concept or theory. For instance, in the field of economics, there might be a research gap in understanding the relationship between income inequality and economic growth.

Methodological gaps

Methodological gaps refer to the absence of appropriate research methods or techniques to study a specific phenomenon. For example, in the field of biology, there might be a research gap in developing a reliable method to detect a certain type of genetic mutation.

Data gaps occur when there is a lack of available data or insufficient data to address a research question. For instance, in the field of climate science, there might be a research gap in obtaining long-term temperature data for a specific region.

Practical gaps

Practical gaps exist when there is a discrepancy between theoretical knowledge and practical application. For example, in the field of education, there might be a research gap in implementing effective teaching strategies for students with learning disabilities.

Research Gap Analysis Techniques

Carry out a comprehensive literature review.

There are several techniques that can be used to identify research gaps. One common technique is conducting a comprehensive literature review, where researchers examine existing research papers, articles, books, and other relevant sources. By analyzing these materials, researchers can pinpoint what has already been explored and identify areas that require further investigation.

Examining Limitations and Contradictions in Existing Studies

During the literature review, researchers should pay attention to the limitations and gaps in the existing studies. These limitations can include unanswered research questions, contradictory findings, methodological issues, or areas that have not been explored in depth. Researchers can also gain insights by comparing and contrasting the findings, methodologies, and conclusions of different studies within their field, which helps in building a more complete understanding of the topic.

Exploring Interdisciplinary Insights to Identify Gaps

Additionally, researchers can seek inspiration from interdisciplinary fields or related disciplines to identify research gaps. Sometimes, a research gap in one field may have been addressed in another field, and researchers can draw upon these insights to identify areas that have not been explored within their own field. It is important to note that identifying research gaps is not a one-time process. As new studies are published and the field evolves, new gaps may emerge. Therefore, researchers should continuously update their knowledge and review the literature to stay informed about the latest developments and identify new research gaps.

Utilizing Surveys and Interviews for Direct Insights

Another technique is conducting surveys or interviews . This allows researchers to gather information directly from individuals who are knowledgeable in the field. Surveys can be distributed to a large number of participants, while interviews provide more in-depth insights from a smaller group of experts. By collecting data through surveys or interviews, researchers can identify gaps in knowledge or areas where more research is needed. Focus groups are another effective technique for conducting a research gap analysis. In a focus group, a small group of individuals with relevant expertise or experience is brought together to discuss a specific topic. Through group discussions and interactions, researchers can gain valuable insights and identify gaps in knowledge or areas that require further investigation.

Employing Quantitative Analysis to Discover Data Gaps

Quantitative analysis techniques, such as statistical analysis, can also be used to identify research gaps. By analyzing existing data sets, researchers can identify patterns, trends, or gaps in the data that may indicate areas where further research is needed. This type of analysis can provide valuable insights into the gaps in existing knowledge and guide future research directions.

Applying Gap Analysis Frameworks for Structured Assessment

In addition to these techniques, researchers can also use gap analysis frameworks or models to systematically identify and analyze research gaps. These frameworks provide a structured approach to assess the current state of knowledge, determine the desired future state, and identify the gaps that need to be addressed. By using a framework, researchers can ensure a comprehensive analysis of research gaps and develop strategies to bridge those gaps.

Research Gap and Problem Statement

A research problem is a specific issue or question that a researcher wants to investigate. It is the foundation of a research study and provides a clear direction for the research process. The identification of a research gap often leads to the formulation of a research problem.

The problem statement is a constructed sentence that defines the research problem and guides the research question. It helps to clarify the purpose of the study and provides a framework for the research design and research methodology. By addressing the research gap through the problem statement, researchers can contribute to the existing body of knowledge and fill the void in the literature. The research problem becomes the focal point of the study, and the research gap serves as the motivation for conducting the research.

Identifying a research gap and formulating a problem statement are crucial steps in the research process. They ensure that the research study is relevant, meaningful, and contributes to the advancement of knowledge in the field. As a key component of the research framework , the problem statement integrates directly into the overall structure that guides the entire research process, ensuring that all aspects of the investigation are aligned with the identified gaps and research questions.

Bridging the Research Gap

Bridging the research gap is crucial for the advancement of knowledge and the improvement of various fields. It involves closing the divide between research findings and their practical application in real-world settings. By bridging this gap, researchers can ensure that their work has a meaningful impact on society and that it is effectively utilized by practitioners and policymakers.

Effective Collaboration between Researchers and Practitioners

There are several strategies and approaches that can be employed to bridge the research gap. One practical way is to establish collaborations and partnerships between researchers and practitioners. By working together, researchers can gain valuable insights from practitioners’ experiences and expertise, while practitioners can benefit from the latest research findings and evidence-based practices. This collaboration can lead to the development of more relevant and effective solutions to real-world problems.

For facilitating such connections and collaborations, platforms like Researchmate.net are invaluable resources, providing the tools and community needed to bring together researchers and practitioners from diverse fields.

Intermediary Organizations in Facilitating Research Application

Another approach to bridging the research gap is through the use of intermediary organizations. These organizations act as a bridge between researchers and practitioners, facilitating the translation and dissemination of research findings into practical applications. They can provide training, resources, and support to practitioners, helping them to implement evidence-based practices in their work. Intermediary organizations also play a crucial role in promoting knowledge exchange and collaboration between researchers and practitioners.

Enhancing Communication and Knowledge Transfer in Research

Furthermore, bridging the research gap requires effective communication and knowledge transfer. Researchers need to communicate their findings in a clear and accessible manner, using language that is understandable to practitioners and policymakers. This can be achieved through the use of plain language summaries, policy briefs, and other forms of knowledge translation.

Engaging with Practitioners and Policymakers

Additionally, researchers should actively engage with practitioners and policymakers, seeking their input and feedback to ensure that research findings are relevant and applicable to real-world contexts.

In conclusion, exploring the research gap is a critical step in the research process. It helps researchers identify areas where further investigation is needed, contributes to the advancement of knowledge, and drives innovation. By understanding the research gap, researchers can make meaningful contributions to their field and address unanswered questions. Bridging the research gap requires collaboration and commitment from all stakeholders, but the potential benefits are immense.

Innovations pertaining to the ever-evolving needs of the medical and healthcare sciences remain constant. This creates a gap between the rationalized needs of the study and the proposed research question. However, classifying, identifying, and addressing these research gaps require a systematic and precise structured map. Using the Medical Subject Heading (MeSH) terms “Research Gaps” AND “Healthcare” AND “Framework” in MEDLINE, Scopus, and CINAHL databases with the filters yielded no relevant literature. Therefore, this review aims to fill this practical and clinical knowledge gap by developing the Naqvi-Gabr Research Gap Framework through critical synthesis based on extensive research on medical and healthcare research gaps. Fourteen research gaps are distributed for allocation as per the healthcare delivery system approach: developing new treatments or prevention strategies, improving diagnostic tools and techniques, addressing health disparities, and improving access to healthcare services. This structured framework determines the strategic mapping of research gaps corresponding to the nature of the research. The identification and classification of the appropriate research gap led to precise and concise conclusions corresponding to the research process proposed in this study. Hence, the Naqvi-Gabr Research Gap Framework is a valuable tool for determining the potential application of gaps by researchers, policymakers, and other stakeholders with a productive address.

Introduction and background

In the healthcare sciences, research gaps fill various dimensions of healthcare systems, ranging from basic scientific research [ 1 ] to clinical trials [ 2 ] in the healthcare delivery hierarchy [ 3 ]. Identifying a particular research gap is essential for guiding future research [ 4 ] and improving healthcare outcomes specific to the targeted population [ 5 ], interventions [ 6 ], and outcomes [ 7 ] dealing with various challenges and opportunities [ 8 ].

There are several methods for identifying health research gaps, establishing research needs, and determining research priorities, including scoping reviews, systematic reviews, Delphi surveys, expert panels, and stakeholder consultations [ 9 , 10 ]; however, there remains a lacuna of structured universal reference rationalizing the identity and address of the research gaps in medical sciences. Even though, the literature presents knowledge translation closing the gap between evidence and practice [ 11 ], a concise and precise framework for classifying, identifying, and mapping these gaps in healthcare research is required. This builds a need for a universal reference to systematically identify research gaps in the potential need to classify the limitations of the current evidence [ 8 , 12 ]. Hence, this study aimed to determine the different facets of healthcare to derive a comprehensive, explicit, and viable Naqvi-Gabr Research Gap framework to map and bridge the open ends of a hypothesis improving the quality and effectiveness of healthcare research and practice.

Materials and methods

A search was carried out with the Medical Subject Heading (MeSH) terms “Research Gaps” AND “Healthcare” OR “Health” AND “Framework” in MEDLINE, Scopus and CINAHL databases with the filters applied showing results free full-text review articles published in last five years (2018 to 2023) on humans in the English language with the filters yielded no relevant literature. Therefore, this review aims to fill this practical and clinical knowledge gap by developing the Naqvi-Gabr Research Gap Framework through critical synthesis-based extensive research on medical and healthcare research gaps.

The framework identifies 14 research gaps in healthcare sciences following two elements of classification: the characterization of the gaps and the identification and classification of the reason for allocating the gap [ 8 ]. It includes knowledge, evidence, reporting, epidemiological, empirical, prevention, diagnosis, methodological, therapeutic, translation, rehabilitation, health services, theoretical, and conflict gaps [ 9 , 13 ] as shown in Figure ​ Figure1 1 .

Discussions

The types of research gaps explained in the framework are as follows:

1. Knowledge Gap

The knowledge gap in health research refers to unstructured information without evidence, structured evidence-based information, or both. This gap is pertinent when the existing literature is insufficient to answer a particular research question [ 14 ]. The body of knowledge is represented in the framework by a blue-sky area, where the triangle represents evidence. Evidence indicates proven knowledge, both theoretically and empirically. Knowledge is differentiated as evidence-based if it has theoretical and experimental data; otherwise, an evidence gap is identified.

2. Evidence Gap

The evidence gap refers to areas where there is a lack of robust or high-quality scientific evidence to support or guide clinical decision-making or healthcare interventions [ 15 ]. This may involve a scarcity of randomized controlled trials (RCTs), systematic reviews, or meta-analyses of specific interventions or outcomes [ 16 ]. Effectiveness of new treatments stating if new medications, therapies, or surgical procedures are introduced, there may be limited evidence on their safety, efficacy, and long-term outcomes.

3. Reporting Gap

Effective research is characterized by validity and reliability [ 17 ] but following a lack of awareness, the literature lacks detailed specifications of the experimental design, sample size, the component of the drugs, or the treatment protocol followed, limiting the repetition of the experiments [ 18 ]. This may be because of financial conflicts or trading concerns, restricting the utility of the right to report, and hence, can be considered a reporting gap. Identifying the reporting gap would motivate researchers to try the same experiments and report missing segments in the body of evidence. Reporting gaps occur when evidence is not reported in sufficient detail to allow for replication or meta-analysis. From another point of view, experiments can be assessed for test-retest reliability, and by default, it is considered an empirical gap [ 19 ], where the accuracy of true experiments should support the main theory.

4. Epidemiological Gap

An epidemiological gap arises when there is insufficient information regarding the distribution and determinants of a disease or health condition in a particular population [ 20 ]. Epidemiological studies play a critical role in the understanding of the transmission dynamics of infectious diseases. However, there may be gaps in knowledge regarding the modes of transmission, reservoirs, and factors influencing disease spread, particularly for emerging or re-emerging infections. The population gap in health sciences refers to the under representation or insufficient inclusion of specific populations in studies and clinical trials [ 21 ], leading to a limited understanding of health outcomes and interventions on the basis of criteria including gender-based gaps referring to the biomedical research traditionally focused on males, leading to a lack of understanding of women's health needs and treatment responses [ 22 ]; racial and ethnic gaps referring to the disparities in health outcomes and disease prevalence existing due to limited representation and data from diverse racial and ethnic groups in research studies [ 23 ]; age-related gaps imposing under representation of older adults in clinical trials limiting knowledge about effective treatments and interventions for this population; socioeconomic gaps covering the lower socioeconomic status can hinder research participation, resulting in inadequate representation and limited understanding of health outcomes among disadvantaged populations; and geographic gaps involving research conducted in specific regions may not accurately represent populations from rural or remote areas, impacting the generalizability of findings and interventions.

5. Empirical Gap

The other part of the evidence is empirical or experimental [ 19 ]. The postulated theories require experimental support to withstand or outstand the hypotheses identified. Thus, this creates an empirical gap. An empirical study is a procedure undertaken to support or refute a hypothesis or determine the efficacy of something previously overlooked. Experiments provide insight into cause-and-effect by demonstrating the outcome when any associated variable is altered. It aims to identify areas where there is a lack of data, or where the available data are inconsistent or incomplete. This gap represents a sensitive research area to expand knowledge [ 15 ], address unanswered questions, and provide a solid evidence base for healthcare practice. Identifying empirical gaps is an essential step in the research process as it helps researchers and policymakers determine the focus of their research question and allocate resources effectively. By addressing this gap, researchers can contribute to advancements in healthcare, improve patient outcomes, and synthesize evidence-based decision-making for practitioners. There may be gaps in the empirical evidence [ 24 ] regarding the effectiveness of preventive interventions, such as vaccinations, screening programs, or lifestyle modifications, in reducing the incidence or progression of diseases.

6. Prevention Gap

The prevalence of chronic diseases places a significant burden on healthcare worldwide following a lack of effective prevention strategies, implementation, or research for a specific health condition in specific populations or subgroups, particularly in low-resource settings or marginalized communities, which is referred to as the prevention gap. As per the research gap framework, it is considered a part of the methodology, but it has an impact on health services, which require adequate funds and health authorities to ensure the effective delivery of the disease prevention program to the population. The National Institutes of Health (NIH) Office of Disease Prevention (ODP) [ 25 ], National Academies [ 26 ], US Preventive Services Task Force (USPSTF) [ 27 ], and JAMA Network [ 28 ] identify and report this gap.

7. Diagnosis Gap

In remote healthcare settings, access to advanced diagnostic tools, specialized tests, or experienced healthcare professionals is limited. This results in a diagnostic gap, as patients may not receive timely and accurate diagnoses owing to resource constraints [ 29 ]. The diagnosis gap refers to the difference between the provisional diagnosis and the final diagnosis of a disease or condition. This gap can occur due to a lack of knowledge or skill of the treating doctors, noncompliance with standard diagnostic criteria, or statutory lapses by hospital authorities in the documentation of medical records [ 30 ]. The diagnostic and diagnosis gaps are significant issues in global health, particularly in low- and middle-income countries where the diagnostic capacity gap in primary care is enormous. This cannot be completely accessed with the existing diagnostic facilities, many of which are costly, require laboratory infrastructure, and are highly trained operators. The diagnostic gap is also a significant issue in the diagnosis of tuberculosis, where gaps can occur owing to the use of suboptimal diagnostic tests, lack of specialty services, knowledge and behavior of healthcare professionals, attitude and behavior of patients, and poor adherence to programmatic diagnosis algorithms [ 31 ]. The diagnostic gap is also an issue in hypertension, in which a significant percentage of the population has not been diagnosed [ 18 ]. Finally, a diagnostic gap can occur in rare diseases, where individuals may experience gaps between symptoms, diagnosis, and treatment when in need of care. The diagnostic gap originates as a part of the research methodology, and in turn, it depends on health services such as funds, caregiver experiences, and health authorities.

8. Methodological Gap

While conducting an experimental study, a group of participating subjects served as a representative of the entire population from which they were recruited, overlaying radical results irrespective of effects [ 32 ], and creating a gap, which is called the methodological gap. This occurs when there is a lacuna in the research methodology or design. If a study on the effectiveness of a drug includes only a specific age group or excludes individuals with comorbidities, the findings may not be generalizable to the broader population, leading to a methodological gap. This methodological gap may highlight faults in the choice of research design or the type of statistical analysis that enhances research bias and affects the reliability of the research results. Therefore, researchers have attempted to repeat the same experimental study using different statistical analyses or study designs to obtain more accurate results, focusing on the validity and reliability of measurement tools [ 17 ]. Identifying methodological gaps is important because it can lead to more reliable research outcomes. Researchers should identify methodological gaps at each stage of the research process to ensure that the research is unbiased until completion.

9. Therapeutic Gap

For instance, in rare disorders, a therapeutic gap can be identified, and effective treatment is lacking. It is considered a gap of methodological origin [ 32 ]; however, the limited access to effective existent treatment due to the cost effect of lack of accessibility, as in developing countries, makes it a health-services-dependent gap. Mental health disorders such as depression, anxiety, and schizophrenia often face therapeutic gaps. Existing treatments may not be effective in all patients, and there is a need for improved interventions with better efficacy and tolerability. Developing innovative therapies [ 25 ], exploring new target drugs, and advancing psychotherapeutic approaches are essential for filling this therapeutic gap.

10. Translation Gap

While testing the hypothesis of RCTs [ 33 ], the probability of errors was sustained. This creates a gap in the availability of treatment but lacks applicability only within a part of the therapeutic effect called the translational gap. These gaps arise when evidence from RCTs is not effectively translated into clinical practice [ 9 ]. For example, if a highly effective intervention is not widely and properly adopted in clinical practice or not conducted effectively, it may lead to misleading results that specify a gap in the translation of knowledge.

11. Rehabilitation Gap

The rehabilitation gap refers to the lack of access to evidence-based rehabilitation along with physical therapy at all stages of care. This gap appears to be caused by patients being allowed (or able to afford) a certain number of appointments [ 34 ]. The rehabilitation gap refers to the period after a patient has undergone surgery or treatment but before they have fully recovered, during which they may not have access to physical therapy or may be prohibited by the cost effects, referring to the health service-dependent gap. The rehabilitation gap originated from the methodology of the research but the narrowed research to practice translation restricts the knowledge application.

12. Health Service Gap

Experimental studies require funds, approval from governmental ethical committees, and an eligible healthcare delivery system [ 9 ]. Hence, the health services gap can originate from a lack of supporting funds, healthcare delivery, or the powers of healthcare authorities [ 3 ]. Health service gaps occur when there is a lack of access to or availability of healthcare services for a particular health condition [ 6 ]. Health service gaps may also occur when research on the effectiveness and cost-effectiveness of certain healthcare services is lacking.

13. Theoretical Gap

When the postulated theories fail to address a concept or a phenomenon, it creates a gap of limitations of existing theories or frameworks, termed a theoretical gap. The clinical trials or comparative studies planned based on theories determine the overlooked segments of either the interpretation or explanation of the theory. This approach seeks the revision of the existing concept or the proposal of a novel concept [ 19 , 35 ].

14. Conflict Gap

Conflict Gap occurs when two or more research studies have different findings, results, or conclusions regarding the same research question. So the research question that needs to be answered is which of the conflicted results is true creating the conflict gap to be addressed [ 36 ]. On the other hand, a conflict gap might be present between the theories used to describe the same concept or phenomena making it a theoretical conflict gap.

Conclusions

Identifying and addressing research gaps in the medical and healthcare sciences are crucial for improving healthcare outcomes. This study highlights a structured universal framework inculcating various research gaps and emphasizes the importance of targeted research efforts and evidence-based interventions to bridge these gaps. Collaboration among researchers, clinicians, and policymakers is necessary to prioritize research funding and translate research findings into clinical practice. By addressing these gaps, healthcare services can be advanced, patient outcomes can be improved, and decision-making can be alleviated. Future research should focus on developing strategies to close these gaps and ensure high-quality and effective healthcare research and practices.

Table of Contents

If you are a young researcher, or even still finishing your studies, you’ll probably notice that your academic environment revolves around certain research topics, probably linked to your department or to the interest of your mentor and direct colleagues. For example, if your department is currently doing research in nanotechnology applied to medicine, it is only natural that you feel compelled to follow this line of research. Hopefully, it’s something you feel familiar with and interested in – although you might take your own twists and turns along your career.

Many scientists end up continuing their academic legacy during their professional careers, writing about their own practical experiences in the field and adapting classic methodologies to a present context. However, each and every researcher dreams about being a pioneer in a subject one day, by discovering a topic that hasn’t been approached before by any other scientist. This is a research gap.

Research gaps are particularly useful for the advance of science, in general. Finding a research gap and having the means to develop a complete and sustained study on it can be very rewarding for the scientist (or team of scientists), not to mention how its new findings can positively impact our whole society.

How to Find a Gap in Research

How many times have you felt that you have finally formulated THAT new and exciting question, only to find out later that it had been addressed before? Probably more times than you can count.

There are some steps you can take to help identify research gaps, since it is impossible to go through all the information and research available nowadays:

• Select a topic or question that motivates you: Research can take a long time and surely a large amount of physical, intellectual and emotional effort, therefore choose a topic that can keep you motivated throughout the process.
• Find keywords and related terms to your selected topic: Besides synthesizing the topic to its essential core, this will help you in the next step.
• Use the identified keywords to search literature: From your findings in the above step, identify relevant publications and cited literature in those publications.
• Look for topics or issues that are missing or not addressed within (or related to) your main topic.
• Read systematic reviews: These documents plunge deeply into scholarly literature and identify trends and paradigm shifts in fields of study. Sometimes they reveal areas or topics that need more attention from researchers and scientists.

Keeping track of all the new literature being published every day is an impossible mission. Remember that there is technology to make your daily tasks easier, and reviewing literature can be one of them. Some online databases offer up-to-date publication lists with quite effective search features:

• Elsevier’s Scope
• Google Scholar

Of course, these tools may be more or less effective depending on knowledge fields. There might be even better ones for your specific topic of research; you can learn about them from more experienced colleagues or mentors.

Literature Gap

The expression “literature gap” is used with the same intention as “research gap.” When there is a gap in the research itself, there will also naturally be a gap in the literature. Nevertheless, it is important to stress out the importance of language or text formulations that can help identify a research/literature gap or, on the other hand, making clear that a research gap is being addressed.

When looking for research gaps across publications you may have noticed sentences like:

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

These expressions often indicate gaps; issues or topics related to the main question that still hasn’t been subject to a scientific study. Therefore, it is important to take notice of them: who knows if one of these sentences is hiding your way to fame.

How to Identify Gaps in Research: Tips to Speed Up the Process

If you have ever wondered how to identify research gaps, well, you’re not alone. All researchers looking to make a solid contribution to their field need to start by identifying a topic or issue that hasn’t been tackled before and coming up with possible solutions for it. This is where learning what is a research gap, knowing about some research gap examples, and knowing how to identify research gaps becomes important. Through this article, we will try answering these questions for you.

Table of Contents

What is a research gap ?  

Research gaps are areas requiring more studies or research. 1  They can be:   

• an unsolved question or problem within your field.   
• a case where inconclusive or contradictive results exist.   
• a new concept or idea that hasn’t been studied.   
• a new/updated research to replace the outdated existing research.   
• a specific demographic or location that has not been well studied.   

Why is it important to identify research gaps ?  

Identifying and prioritizing research gaps  is an essential part of any research for the following reasons. 2  This can help you:  

• ensure the rapid generation of subsequent research that is informed by input from previous research studies.    
• understand areas of uncertainty within the research problem.   
• establish the research problem and scope of the study.   
• determine the scope of funding opportunities.   

Identifying research gaps : A challenge for early researchers  

Coming up with original, innovative ideas in your chosen area of research can be tricky, especially if you are an early career researcher, for the following reasons: 3,4

• Enormous information available : The introduction, discussion, and future research sections in published research articles provide information about gaps in the research field. It is easy to get overwhelmed and feel confused about which one to address. Using digital tools can help you seek out popular topics or the most cited research papers.   
• Difficulty in organizing the data : One can quickly lose ideas if not appropriately noted. Mapping the question to the resource and maintaining a record can help narrow research gap s.  
• Fear of challenging the existing knowledge : Beginner researchers may not feel confident to question established norms in their field. A good plan of action would be discussing such ideas with your advisor and proceeding according to their feedback or suggestions.   
• Lack of direction and motivation : Early researchers have reported negative emotions regarding academic research, including feeling directionless or frustrated with the effort required in identifying research topics. Again a good advisor can help you stay focused. Mentors can help novice researchers avoid cases with a high risk of failure, from misunderstanding the literature, weak design, or too many unknowns. Talking with other fellow researchers can also help overcome some of the anxiety.

How to identify research gaps  in the literature  

More than 7 million papers get published annually. 5  Considering the volume of existing research, identifying research gaps  from existing literature may seem a daunting task. While there are no hard rules for identifying research gaps, the literature has provided some guidelines for identifying problems worth investigating.   

1. Observe : Personal interests and experiences can provide insight into possible research problems. For example, a researcher interested in teaching may start with a simple observation of students’ classroom behavior and observe the link with learning theories. Developing the habit of reading literature using smart apps like  R Discovery   can keep you updated with the latest trends and developments in the field.   

2. Search : Exploring existing literature will help to identify if the observed problem is documented. One approach is identifying the independent variables used to solve the researcher’s topic of interest (i.e., the dependent variable). Databases such as Emerald, ProQuest, EbscoHost, PubMed, and ScienceDirect can help potential researchers explore existing research gaps. The following steps can help with optimizing the search process once you decide on the key research question based on your interests.

-Identify key terms.

-Identify relevant articles based on the keywords.

-Review selected articles to identify gaps in the literature.  

3. Map : This involves mapping key issues or aspects across the literature. The map should be updated whenever a researcher comes across an article of interest.   

4. Synthesize : Synthesis involves integrating the insights of multiple but related studies. A research gap is identified by combining results and findings across several interrelated studies. 6

5. Consult:  Seeking expert feedback will help you understand if the  research gaps identified are adequate and feasible or if improvements are required.  

6. Prioritize : It is possible that you have identified multiple questions requiring answers. Prioritize the question that can be addressed first, considering their relevance, resource availability, and your research strengths.  

7. Enroll : Research Skills Development Programs, including workshops and discussion groups within or outside the research institution, can help develop research skills, such as framing the research problem. Networking and corroborating in such events with colleagues and experts might help you know more about current issues and problems in your research domain.   

While there is no well-defined process to identify gaps in knowledge, curiosity, judgment, and creativity can help you in identifying these research gaps . Regardless of whether the  research gaps identified are large or small, the study design must be sufficient to contribute toward advancing your field of research.

Frequently Asked Questions (FAQs)

Question: How can research gaps be addressed?

Research gaps can be addressed by conducting further studies, experiments, or investigations that specifically target the areas where knowledge is lacking or incomplete. This involves conducting a thorough literature review to identify existing gaps, designing research methodologies to address these gaps, and collecting new data or analyzing existing data to fill the void. Collaboration among researchers, interdisciplinary approaches, and innovative research designs can also help bridge research gaps and contribute to the advancement of knowledge in a particular field.

Question: Can research gaps change over time?

Yes, research gaps can change over time. As new studies are conducted, technologies advance, and societal needs evolve, gaps in knowledge may be identified or existing gaps may become more pronounced. Research gaps are dynamic and subject to shifts as new discoveries are made, new questions arise, and priorities change. It is crucial for researchers to continuously assess and update their understanding of the field to identify emerging research gaps and adapt their research efforts accordingly.

Question: Are research gaps specific to a particular discipline or field?

Research gaps can exist within any discipline or field. Each discipline has its own unique body of knowledge and areas where understanding may be limited. Research gaps can arise from unanswered questions, unexplored phenomena, conflicting findings, practical challenges, or new frontiers of knowledge. They are not limited to a specific discipline or field, as gaps can exist in natural sciences, social sciences, humanities, engineering, or any other area of study.

Question: How can research gaps contribute to the research proposal?

Research gaps play a significant role in the development of research proposals. They help researchers identify a clear rationale and justification for their study. By addressing identified gaps in knowledge, researchers can demonstrate the significance and relevance of their proposed research. Research proposals often include a literature review section that highlights existing gaps and positions the proposed study as a contribution to the field. By explicitly addressing research gaps, researchers can strengthen the credibility and importance of their research proposal, as well as its potential impact on advancing knowledge and addressing critical questions or challenges.

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.

ARTICLE/RESEARCH: A Taxonomy of Research Gaps: Identifying and Defining the Seven Research Gaps

2017, Journal of Research Methods and Strategies

One of the most prevailing issues in the craft of research is to develop a research agenda and build the research on the development of the research gap. Most research of any endeavor is attributed to the development of the research gap, which is a primary basis in the investigation of any problem, phenomenon or scientific question. Given this accepted tenet of engagement in research, surprising in the research fraternity, we do not train researchers on how to systematically identify research gaps as basis for the investigation. This is has continued to be a common problem with novice researchers. Unfailingly, very little theory and research has been developed on identifying research gaps as a basis for a line in inquiry. The purpose of this research is threefold. First, the proposed theoretical framework builds on the five-point theoretical model of Robinson, Saldanhea, and McKoy (2011) on research gaps. Second, this study builds on the six-point theoretical model of Müller-Bloch and Franz (2014) on research gaps. Lastly, the purpose of this research is to develop and propose a theoretical model that is an amalgamation of the two preceding models and re-conceptualizes the research gap concepts and their characteristics. Thus, this researcher proposes a seven-point theoretical model. This article discusses the characteristics of each research and the situation in which its application is warranted in the literature review The significance of this article is twofold. First, this research provides theoretical significance by developing a theoretical model on research gaps. Second, this research attempts to build a solid taxonomy on the different characteristics of research gaps and establish a foundation. The implication for researchers is that research gaps should be structured and characterized based on their functionality. Thus, this provides researchers with a basic framework for identifying them in the literature investigation.

Various researchers have established the need for researchers to position their research problem in the research gap of the study area. This does not only indicate the relevance of the study but it demonstrates the significant contribution it would make in the field of study. The purpose of this paper is to conduct a systematic literature review on the concept of research gaps and provoke a discussion on the contemporary literature on types of research gaps. The paper discusses the various approaches for researchers to identify, align and position research problems, research design, and methodology in the research gaps to achieve relevance in their findings and study. A systematic review of the current literature on research gaps might assist beginning researchers in the justification of research problems. Given the acceptable tenet of developing a research agenda, design, and development on a research gap, many early career researchers especially (post)graduate students have difficulties in systematically identifying research gaps as a basis for conducting research work. The significance of this paper is twofold. First, it provides a systematic review of literature on the identification of research gaps to undertake research that would challenge assumptions and underlying existing theories in a significant way. Second, it provides a theoretical discussion on the importance of developing research problems on research gaps to structure their study.

Problem in a research as well as human body calls for perfect diagnosis of illness. This is important to avoid treating the symptoms instead of the actual disease. A research problem could be identified through professional or/and academic efforts. This poses a lot of problems to students, both at the undergraduate and postgraduate levels, as this determines the title of their articles or research works. Many of them have to submit many topics to their supervisors before one could be reframed and approved. At times, students appealed to their supervisors to provide them with researchable topics. This to the supervisor(s) almost writing the dissertations/theses for them. The argument of this paper is to let students understand "problem identification" using an analogy from the Holy Bible. The study employed a conversation analysis methodology, which is empirically grounded, exploratory in process and inferential. This involves using every conversation between two or more parties to explore facts/lesson. It was recommended that seasoned lecturers should explain to students how to identify research problems using what are familiar to them to make them understand this important aspect of research.

A research gap is generally any problem a scientific article, an academic book or a thesis may contain. In the previous article [https://discourse.clevious.com/2019/12/how-to-come-up-with-research-idea.html], based on Dr. Anthony Miles' article on research gaps, I summarized the 7 research gaps into three main categories: theoretical problems, reasoning problems, and empirical problems.

The basics of research are seemingly clear. Read a lot of articles, see what’s missing, and conduct research to fill the gap in the literature. Wait a minute. What is that? “See what’s missing?” How can we see something that is not there? In this post, we will show you how to “see the invisible;” How to identify the missing pieces in any study, literature review, or program analysis. With these straight-forward techniques, you will be able to better target your research in a more cost-effective way to fill those knowledge gaps to develop more effective theories, plans, and evaluations.

Researchers and academia often have difficulties identifying the research gap in literature in various fields of study. Hence, exploring research gap is one of the most arduous tasks for researchers especially those at the preliminary stage. The explicit identification of research gap is an inevitable step in developing a research agenda including decision about funding and the design of informative studies. Thus, to identify the research gap, the researcher needs to prune down his area of interest as identifying research gaps requires a lot of reading and analyzing of materials from various literatures. Hence, this study explores literatures regarding the method of identifying research gaps in management sciences. This was done by extensively examining various literatures on the method of identifying research gaps from previous researchers. However, the study made use of content analysis to identify research gaps in some articles. This study revealed that researchers are focused on a single type of research gap, leaving other research gaps unexplored. Also, there are some methods of research identification that has remained understandable by researchers as there are little or no knowledge about them. Hence, the study recommended among others that the various research identification methods be explored by researchers who intend to engage in studies in this field of management sciences.

This section contains the four Thematic Gap Analyses and the Cross-Cutting Gap Analysis. Each of the chapters has a lead author (s) as noted on the front page of the chapter. This follows the way that the team has divided-up the responsibilities for each Thematic Area, with a disciplinary specialist (s) taking the lead on each area. The chapters have, however, been reviewed and commented by others in the project team so the analysis and suggested actions and conclusions have the general support of the full project team.

In this second part of The Reason to Replicate Research, I develop with more details and explanations the Reasoning Gaps idea I briefly discussed in the article “How to Come Up with Research Question Easily Like a Pro”. (https://discourse.clevious.com/2019/12/how-to-come-up-with-research-idea.html) And just like in Part I (https://discourse.clevious.com/2020/01/the-empirical-gap-to-replicate-research.html), I will try to pivot the explanation around an example and show why they are important to fill.

How to Identify and Address Research Gaps

Research is the driving force behind scientific progress and innovation. It involves exploring uncharted territories, seeking answers to unanswered questions, and  pushing the boundaries of knowledge . However, no research is perfect, and there are always opportunities for improvement. This is where identifying and addressing research gaps becomes crucial.

What is a Research Gap?

Research gaps are the areas within a particular field of study where existing knowledge falls short. These gaps represent unanswered questions, unresolved controversies, or unexplored dimensions. Identifying and addressing these gaps is essential for advancing knowledge and ensuring that research efforts are focused on areas that truly need attention.

Research gaps can arise due to various factors such as technological limitations, methodological constraints, or simply the complexity of the subject matter. These gaps allow researchers to uncover new insights and contribute to the existing body of knowledge.

By identifying these gaps in knowledge, researchers can  refine their research objectives  and strategies. Pinpointing research gaps can also lead to interdisciplinary collaborations; this cross-pollination of ideas and expertise can result in innovative solutions and a more holistic approach to addressing research challenges. In addition, addressing research gaps can have practical implications, such as informing policy decisions, guiding future research directions, and ultimately improving the quality of life for individuals and communities.

Exploring Different Types of Research Gaps

Research gaps can be categorized based on their nature and characteristics. These categories include conceptual, empirical, methodological, and theoretical gaps. Each type of gap requires specific strategies for identification and subsequent resolution.

The Distinct Characteristics of Different Research Gaps

Conceptual gaps exist when there is a lack of consensus or clarity in defining key concepts within a field. Empirical gaps arise when there is a dearth of data or evidence on a specific topic. Methodological gaps occur when existing research methods are inadequate for addressing certain research questions. Theoretical gaps arise when there are discrepancies or limitations in the theoretical frameworks used in a particular field.

Conceptual gaps often lead to debates among scholars regarding the fundamental principles and definitions that underpin a research area. Researchers may need to conduct extensive literature reviews and engage in critical discussions to bridge these conceptual divides. On the other hand, empirical gaps may require researchers to design and implement new studies or experiments to gather the necessary data to fill the void.

Methodological gaps pose challenges for researchers in selecting appropriate research designs and data collection methods. Addressing these gaps may involve exploring innovative methodologies or adapting existing techniques to suit the research context. Theoretical gaps, while essential for advancing knowledge, can create opportunities for interdisciplinary collaborations and the integration of diverse perspectives to enrich the theoretical landscape of a field.

The Classic Literature Gap

One of the most common types of research gaps is the classic literature gap. It occurs when previous studies have failed to adequately address a specific aspect or angle of a topic. A literature gap may arise due to the limited scope of previous research, gaps in the research methodologies employed, or the absence of recent studies that account for new findings or perspectives.

Exploring the classic literature gap in depth reveals the intricate web of interconnected ideas and themes that have shaped the discourse on a particular subject over time. By examining the historical evolution of scholarly works, researchers can uncover nuances and connections that more recent studies may have overlooked.

Bridging the classic literature gap requires a multidimensional approach that goes beyond simply filling in the missing pieces of the puzzle.

Researchers must critically analyze the existing literature, identify key themes and patterns, and propose innovative ways to build upon the foundational works that have laid the groundwork for current research. By engaging with literature in a meaningful way, scholars can enrich their understanding of the subject matter and contribute to the ongoing dialogue in their respective fields.

The Disagreement Gap

The disagreement gap arises when conflicting or inconsistent findings exist in the existing literature. This type of gap highlights the need for further research to reconcile these discrepancies and establish a more accurate understanding of the topic. Identifying and addressing the sources of disagreement through rigorous investigation is essential for progress within the field.

One common reason for a disagreement gap is the variability in research methodologies employed by different studies. Factors such as sample size, data collection techniques, and analytical tools can all contribute to divergent results. For instance, a study utilizing a small sample size may yield different conclusions than a study with a larger, more diverse sample. Understanding these methodological differences is crucial in interpreting conflicting findings and moving toward consensus in the research community.

Furthermore, external factors such as funding sources, researcher bias, and publication bias can also influence the disagreement gap. Research funded by certain organizations may have inherent biases that impact the study outcomes. Similarly, researchers may have preconceived notions or preferences that unconsciously influence their interpretations of data. Addressing these external influences requires transparency, peer review, and a commitment to objective analysis to bridge the gap and advance knowledge in the field.

The Contextual Gap

The contextual gap occurs when research findings applicable in one context may not be applicable or relevant in another. This type of gap emphasizes the importance of considering the specific contextual factors that might influence the outcomes or applicability of research findings. Addressing this gap involves conducting research in different contexts to obtain a more comprehensive understanding of the topic.

The Methodological Gap

The methodological gap arises when existing research methods cannot adequately address specific research questions or objectives. It may be due to limitations in data collection, inappropriate analysis techniques, or other methodological drawbacks. Bridging this gap requires the development of innovative research approaches or the adaptation of existing methodologies to suit the unique requirements of the research question.

What is the Difference Between Research Gap and Research Problem

The main difference between research gap and research problem is that a research gap identifies a gap in knowledge about a subject, whereas a research problem identifies and articulates the need for research .

Research gap and research problem are two very similar elements of a research study. They are closely related and play a crucial role in research. In fact, a researcher cannot identify a research problem without a research gap, and it’s impossible to conduct a research study without both. A researcher first identifies a research gap (an area that has not been explored in previous literature on the subject) after conducting a thorough literature review . Then he/she formulates a clear research problem from this research gap.

What is a Research Gap

A research gap is a key element in any research study. It’s the center of a research project and determines the area that lacks crucial information. We can define a research gap as a question that has not been addressed or an area of interest that has not been explored in previous literature on the subject. For example, a researcher in the field of health or medicine can research the long-term effects of Covid-19 vaccines, which is a research gap in the existing literature on the subject. To identify the research gap, the researcher has to gather and study all relevant books, reports, and journal articles on the subject. Researchers can usually decide on their research gap once they have conducted their literature review.

A research gap can exist when there are no studies on a new concept or idea. Sometimes, researchers can also find a research gap if the existing research is not up to date and needs modification or updates. For example, research on internet use in 2002 is no longer valid today, and the data needs modification. A researcher can also choose a specific population that has not been studied well.

What is a Research Problem

A research problem is a question(s) the researcher wants to answer through his study. Research problems introduce the readers to the topic that is being discussed. It also places the problem in a particular context, defining the parameters of the investigation. Finally, it provides the framework for reporting the results of the research, reveals what is necessary to conduct the research, and explains how the information will be presented.

A research problem must cover the essential issues at hand and be specific. Moreover, the researcher must present it logically and clearly. The research problem must also ensure that the research is based on actual facts and evidence and not on beliefs and opinions.

There are four general types of research problems:

• Casuist Research Problem – involves the determination of right and wrong in questions of conduct or conscience
• Difference Research Problem – compares and contrasts two or more phenomena
• Descriptive Research Problem – describes the significance of a state, situation, phenomenon
• Relational Research Problem – indicates a relationship between two or more variables

Without a well-defined research problem, a researcher will be more likely to end up with an unfocused and unmanageable research study.

Difference Between Research Gap and Research Problem

A research gap is an area of interest that has not been explored in previous literature on the subject, while a research problem is a definite or clear statement about an area of concern that points to a need for meaningful understanding and deliberate investigation.

First, the researcher has to identify a research gap in the area of interest and then form his/her research problem.

A research gap identifies a gap in knowledge about a subject, whereas a research problem identifies and articulates the need for research.

A researcher identifies a research gap after conducting a thorough literature review. Then he/she formulates a clear research problem from this research gap. Therefore, the difference between research gap and research problem is the order of sequence. A research gap further justifies the research problem.

Metrics details

Cerebral palsy (CP) is associated with substantial deficits in muscle performance, as demonstrated by muscle weakness 1 and low power generation. 2 The major consequence is an inability or limited ability to execute basic daily activities. 3

Low muscle performance in children with CP stems from their smaller size, 1 higher infiltration of fat, 4 and lower voluntary neuromuscular activation 1 and mitochondrial capacity 5 , 6 when compared to typically developing children. Other contributing factors are spasticity, 7 long sarcomeres and collagen infiltration, which are associated with increased muscle stiffness, 8 and excessive co-contraction of muscles, 9 which is associated with fewer muscle synergies and a simplified motor control strategy. 10 Altered brain activation patterns, such as suppressed activation of the prefrontal cortex, may also contribute to poor muscle performance. 11 Muscle contractures, which represent a permanent shortening of the muscle-tendon complex, 12 are present in more than 1/3 of children with CP and begin to show significant signs of developing by four years of age. 13 When coupled with the limited participation in physical activity and early signs of increased chronic disease risk, such as cardiometabolic disease 14 and osteoporosis, 15 , 16 the critical need for early tracking and treatment of muscle in children with CP is evident. 16

Comprehensive framework to promote diversity, equity, and inclusion in global biodiversity research

by Jose Valdez, German Centre for Integrative Biodiversity Research (iDiv) Halle-Jena-Leipzig

The global biodiversity crisis demands comprehensive, collaborative solutions that draw upon diverse knowledge and perspectives from around the world. Yet, a critical gap exists in biodiversity research, where the expertise and insights of local scientists and communities in biodiversity-rich regions are frequently overlooked and undervalued.

Local experts in these underrepresented regions possess invaluable knowledge but face significant barriers to having their research recognized and integrated into global conservation efforts. This disconnect leads to conservation priorities being set by individuals detached from the source environments and cultures, resulting in strategies that fail to account for critical local contexts, ultimately undermining the effectiveness of biodiversity conservation.

To address this challenge, we—an international team of researchers from underrepresented backgrounds and biodiversity-rich regions—developed a comprehensive framework to promote diversity, equity, and inclusion in global biodiversity research.

Published in the journal Conservation Biology , this holistic approach of collective responsibility provides tangible strategies for researchers, institutions, publishers, and funders to work together in dismantling systemic barriers.

In our article, we identify four key challenges hindering equitable participation in biodiversity research:

• Linguistic bias: The dominance of English in scientific publishing creates barriers for non-native speakers and limits the dissemination of research conducted in other languages.
• Undervalued research contributions: Important research from underrepresented regions and non-English publications is often overlooked, leading to a skewed representation of global biodiversity knowledge.
• Parachute science and extractive practices: External researchers conducting studies without meaningful local collaboration fail to account for cultural context and local needs.
• Capacity constraints: Researchers from underrepresented regions often face limited access to funding, resources, and training opportunities, hindering their ability to participate fully in global research efforts.

To overcome these systemic barriers, our framework calls for coordinated, cross-stakeholder efforts. Achieving meaningful progress requires everyone involved in biodiversity research to recognize their role and take action. As interconnected participants, we all share the responsibility to cultivate a more inclusive and equitable research environment.

For researchers, this means expanding literature searches to non-English languages, fostering local partnerships, and actively promoting knowledge exchange. Institutions are encouraged to establish specialized liaison roles, implement equitable policies, and provide greater support for international collaborations. Publishers can facilitate multilingual dissemination and ensure equitable representation in peer review. Funding bodies, in turn, must start to remove systemic barriers and prioritize equitable resource allocation.

Regardless of our roles, we must promote good scientific practices that amplify underrepresented voices and dismantle biases. Inclusivity is not just an ethical imperative; diverse collaborations yield more robust science that directly informs locally relevant and culturally sensitive conservation action.

With this framework of shared responsibility, the biodiversity research community can empower underrepresented voices, integrate local and Indigenous knowledge, and maximize our collective impact for effective global conservation—unlocking new possibilities to address the biodiversity crisis.
