a researcher writing the rationale for a research paper

The rationale for your research is the reason why you decided to conduct the study in the first place. The motivation for asking the question. The knowledge gap. This is often the most significant part of your publication. It justifies the study's purpose, novelty, and significance for science or society. It's a critical part of standard research articles as well as funding proposals.

Essentially, the research rationale answers the big SO WHAT? that every (good) adviser, peer reviewer, and editor has in mind when they critique your work.

A compelling research rationale increases the chances of your paper being published or your grant proposal being funded. In this article, we look at:

  • the purpose of a research rationale
  • its components and key characteristics
  • how to create an effective research rationale

What is a research rationale?

Think of a research rationale as a set of reasons that explain why a study is necessary and important based on its background. It's also known as the justification of the study, rationale, or thesis statement.

Essentially, you want to convince your reader that you're not reciting what other people have already said and that your opinion hasn't appeared out of thin air. You've done the background reading and identified a knowledge gap that this rationale now explains.

A research rationale is usually written toward the end of the introduction. You'll see this section clearly in high-impact-factor international journals like Nature and Science. At the end of the introduction there's always a phrase that begins with something like, "here we show..." or "in this paper we show..." This text is part of a logical sequence of information, typically (but not necessarily) provided in this order:

the order of the introduction to a research paper

Here's an example from a study by Cataldo et al. (2021) on the impact of social media on teenagers' lives.

an example of an introduction to a research paper

Note how the research background, gap, rationale, and objectives logically blend into each other.

The authors chose to put the research aims before the rationale. This is not a problem though. They still achieve a logical sequence. This helps the reader follow their thinking and convinces them about their research's foundation.

Elements of a research rationale

We saw that the research rationale follows logically from the research background and literature review/observation and leads into your study's aims and objectives.

This might sound somewhat abstract. A helpful way to formulate a research rationale is to answer the question, “Why is this study necessary and important?”

Generally, that something has never been done before should not be your only motivation. Use it only If you can give the reader valid evidence why we should learn more about this specific phenomenon.

A well-written introduction covers three key elements:

  • What's the background to the research?
  • What has been done before (information relevant to this particular study, but NOT a literature review)?
  • Research rationale

Now, let's see how you might answer the question.

1. This study complements scientific knowledge and understanding

Discuss the shortcomings of previous studies and explain how'll correct them. Your short review can identify:

  • Methodological limitations . The methodology (research design, research approach or sampling) employed in previous works is somewhat flawed.

Example : Here , the authors claim that previous studies have failed to explore the role of apathy “as a predictor of functional decline in healthy older adults” (Burhan et al., 2021). At the same time, we know a lot about other age-related neuropsychiatric disorders, like depression.

Their study is necessary, then, “to increase our understanding of the cognitive, clinical, and neural correlates of apathy and deconstruct its underlying mechanisms.” (Burhan et al., 2021).

  • Contextual limitations . External factors have changed and this has minimized or removed the relevance of previous research.

Example : You want to do an empirical study to evaluate the effects of the COVID-19 pandemic on the number of tourists visiting Sicily. Previous studies might have measured tourism determinants in Sicily, but they preceded COVID-19.

  • Conceptual limitations . Previous studies are too bound to a specific ideology or a theoretical framework.

Example : The work of English novelist E. M. Forster has been extensively researched for its social, political, and aesthetic dimensions. After the 1990s, younger scholars wanted to read his novels as an example of gay fiction. They justified the need to do so based on previous studies' reliance on homophobic ideology.

This kind of rationale is most common in basic/theoretical research.

2. This study can help solve a specific problem

Here, you base your rationale on a process that has a problem or is not satisfactory.

For example, patients complain about low-quality hospital care on weekends (staff shortages, inadequate attention, etc.). No one has looked into this (there is a lack of data). So, you explore if the reported problems are true and what can be done to address them. This is a knowledge gap.

Or you set out to explore a specific practice. You might want to study the pros and cons of several entry strategies into the Japanese food market.

It's vital to explain the problem in detail and stress the practical benefits of its solution. In the first example, the practical implications are recommendations to improve healthcare provision.

In the second example, the impact of your research is to inform the decision-making of businesses wanting to enter the Japanese food market.

This kind of rationale is more common in applied/practical research.

3. You're the best person to conduct this study

It's a bonus if you can show that you're uniquely positioned to deliver this study, especially if you're writing a funding proposal .

For an anthropologist wanting to explore gender norms in Ethiopia, this could be that they speak Amharic (Ethiopia's official language) and have already lived in the country for a few years (ethnographic experience).

Or if you want to conduct an interdisciplinary research project, consider partnering up with collaborators whose expertise complements your own. Scientists from different fields might bring different skills and a fresh perspective or have access to the latest tech and equipment. Teaming up with reputable collaborators justifies the need for a study by increasing its credibility and likely impact.

When is the research rationale written?

You can write your research rationale before, or after, conducting the study.

In the first case, when you might have a new research idea, and you're applying for funding to implement it.

Or you're preparing a call for papers for a journal special issue or a conference. Here , for instance, the authors seek to collect studies on the impact of apathy on age-related neuropsychiatric disorders.

In the second case, you have completed the study and are writing a research paper for publication. Looking back, you explain why you did the study in question and how it worked out.

Although the research rationale is part of the introduction, it's best to write it at the end. Stand back from your study and look at it in the big picture. At this point, it's easier to convince your reader why your study was both necessary and important.

How long should a research rationale be?

The length of the research rationale is not fixed. Ideally, this will be determined by the guidelines (of your journal, sponsor etc.).

The prestigious journal Nature , for instance, calls for articles to be no more than 6 or 8 pages, depending on the content. The introduction should be around 200 words, and, as mentioned, two to three sentences serve as a brief account of the background and rationale of the study, and come at the end of the introduction.

If you're not provided guidelines, consider these factors:

  • Research document : In a thesis or book-length study, the research rationale will be longer than in a journal article. For example, the background and rationale of this book exploring the collective memory of World War I cover more than ten pages.
  • Research question : Research into a new sub-field may call for a longer or more detailed justification than a study that plugs a gap in literature.

Which verb tenses to use in the research rationale?

It's best to use the present tense. Though in a research proposal, the research rationale is likely written in the future tense, as you're describing the intended or expected outcomes of the research project (the gaps it will fill, the problems it will solve).

Example of a research rationale

Research question : What are the teachers' perceptions of how a sense of European identity is developed and what underlies such perceptions?

Research Gap

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.

Setting Rationale in Research: Cracking the code for excelling at research

' src=

Knowledge and curiosity lays the foundation of scientific progress. The quest for knowledge has always been a timeless endeavor. Scholars seek reasons to explain the phenomena they observe, paving way for development of research. Every investigation should offer clarity and a well-defined rationale in research is a cornerstone upon which the entire study can be built.

Research rationale is the heartbeat of every academic pursuit as it guides the researchers to unlock the untouched areas of their field. Additionally, it illuminates the gaps in the existing knowledge, and identifies the potential contributions that the study aims to make.

Table of Contents

What Is Research Rationale and When Is It Written

Research rationale is the “why” behind every academic research. It not only frames the study but also outlines its objectives , questions, and expected outcomes. Additionally, it helps to identify the potential limitations of the study . It serves as a lighthouse for researchers that guides through data collection and analysis, ensuring their efforts remain focused and purposeful. Typically, a rationale is written at the beginning of the research proposal or research paper . It is an essential component of the introduction section and provides the foundation for the entire study. Furthermore, it provides a clear understanding of the purpose and significance of the research to the readers before delving into the specific details of the study. In some cases, the rationale is written before the methodology, data analysis, and other sections. Also, it serves as the justification for the research, and how it contributes to the field. Defining a research rationale can help a researcher in following ways:

Define Your Research Rationale

1. Justification of a Research Problem

  • Research rationale helps to understand the essence of a research problem.
  • It designs the right approach to solve a problem. This aspect is particularly important for applied research, where the outcomes can have real-world relevance and impact.
  • Also, it explains why the study is worth conducting and why resources should be allocated to pursue it.
  • Additionally, it guides a researcher to highlight the benefits and implications of a strategy.

2. Elimination of Literature Gap

  • Research rationale helps to ideate new topics which are less addressed.
  • Additionally, it offers fresh perspectives on existing research and discusses the shortcomings in previous studies.
  • It shows that your study aims to contribute to filling these gaps and advancing the field’s understanding.

3. Originality and Novelty

  • The rationale highlights the unique aspects of your research and how it differs from previous studies.
  • Furthermore, it explains why your research adds something new to the field and how it expands upon existing knowledge.
  • It highlights how your findings might contribute to a better understanding of a particular issue or problem and potentially lead to positive changes.
  • Besides these benefits, it provides a personal motivation to the researchers. In some cases, researchers might have personal experiences or interests that drive their desire to investigate a particular topic.

4. An Increase in Chances of Funding

  • It is essential to convince funding agencies , supervisors, or reviewers, that a research is worth pursuing.
  • Therefore, a good rationale can get your research approved for funding and increases your chances of getting published in journals; as it addresses the potential knowledge gap in existing research.

Overall, research rationale is essential for providing a clear and convincing argument for the value and importance of your research study, setting the stage for the rest of the research proposal or manuscript. Furthermore, it helps establish the context for your work and enables others to understand the purpose and potential impact of your research.

5 Key Elements of a Research Rationale

Research rationale must include certain components which make it more impactful. Here are the key elements of a research rationale:

Elements of research rationale

By incorporating these elements, you provide a strong and convincing case for the legitimacy of your research, which is essential for gaining support and approval from academic institutions, funding agencies, or other stakeholders.

How to Write a Rationale in Research

Writing a rationale requires careful consideration of the reasons for conducting the study. It is usually written in the present tense.

Here are some steps to guide you through the process of writing a research rationale:

Steps to write a research rationale

After writing the initial draft, it is essential to review and revise the research rationale to ensure that it effectively communicates the purpose of your research. The research rationale should be persuasive and compelling, convincing readers that your study is worthwhile and deserves their attention.

How Long Should a Research Rationale be?

Although there is no pre-defined length for a rationale in research, its length may vary depending on the specific requirements of the research project. It also depends on the academic institution or organization, and the guidelines set by the research advisor or funding agency. In general, a research rationale is usually a concise and focused document.

Typically, it ranges from a few paragraphs to a few pages, but it is usually recommended to keep it as crisp as possible while ensuring all the essential elements are adequately covered. The length of a research rationale can be roughly as follows:

1. For Research Proposal:

A. Around 1 to 3 pages

B. Ensure clear and comprehensive explanation of the research question, its significance, literature review , and methodological approach.

2. Thesis or Dissertation:

A. Around 3 to 5 pages

B. Ensure an extensive coverage of the literature review, theoretical framework, and research objectives to provide a robust justification for the study.

3. Journal Article:

A. Usually concise. Ranges from few paragraphs to one page

B. The research rationale is typically included as part of the introduction section

However, remember that the quality and content of the research rationale are more important than its length. The reasons for conducting the research should be well-structured, clear, and persuasive when presented. Always adhere to the specific institution or publication guidelines.

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).

using google scholar to find a research gap

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.

Rationale for Research

What is the Rationale of Research?

The term rationale of research means the reason for performing the research study in question. In writing your rational you should able to convey why there was a need for your study to be carried out. It’s an important part of your research paper that should explain how your research was novel and explain why it was significant; this helps the reader understand why your research question needed to be addressed in your research paper, term paper or other research report.

The rationale for research is also sometimes referred to as the justification for the study. When writing your rational, first begin by introducing and explaining what other researchers have published on within your research field.

Having explained the work of previous literature and prior research, include discussion about where the gaps in knowledge are in your field. Use these to define potential research questions that need answering and explain the importance of addressing these unanswered questions.

The rationale conveys to the reader of your publication exactly why your research topic was needed and why it was significant . Having defined your research rationale, you would then go on to define your hypothesis and your research objectives.

Final Comments

Defining the rationale research, is a key part of the research process and academic writing in any research project. You use this in your research paper to firstly explain the research problem within your dissertation topic. This gives you the research justification you need to define your research question and what the expected outcomes may be.

How to Write a Rationale: A Guide for Research and Beyond

How to Write a Rationale: A Guide for Research and Beyond

Ever found yourself scratching your head, wondering how to justify your choice of a research topic or project? You’re not alone! Writing a rationale, which essentially means explaining the ‘why’ behind your decisions, is crucial to any research process. It’s like the secret sauce that adds flavour to your research recipe. So, the only thing you need to know is how to write a rationale.

Guide

What is a Rationale?

A rationale in research is essentially the foundation of your study. It serves as the justification for undertaking a particular research project. At its core, the rationale explains why the research was conducted or needs to be conducted, thus addressing a specific knowledge gap or research question.

Here’s a breakdown of the key elements involved in crafting a rationale:

Linking Background to Research Question: 

The rationale should connect the background of the study to your specific research question. It involves presenting and discussing existing data on your topic, identifying gaps or issues in the current understanding, and explaining why addressing them is important​.

Objectives and Significance: 

Your rationale should clearly outline your research objectives – what you hope to discover or achieve through the study. It should also emphasize the subject’s significance in your field and explain why more or better research is needed​.

Methodological Approach: 

The rationale should briefly describe your proposed research method , whether qualitative (descriptive) or quantitative (experimental), and justify this choice​.

Justifying the Need for Research: 

The rationale isn’t just about what you’re doing and why it’s necessary. It can involve highlighting methodological, contextual, or conceptual limitations in previous studies and explaining how your research aims to overcome these limitations. Essentially, you’re making a case for why your research fills a crucial gap in existing knowledge​​.

Presenting Before and After Research: 

Interestingly, the rationale can be presented before and after the research. Before the research, it forms a central part of the research proposal, setting out the plan for the work. After the research, it’s presented in a research article or dissertation to explain the focus on a specific research question and link it to the study’s aims and outcomes​.

Elements to Include: 

A good rationale should include a summary of conclusions from your literature review, identify what is currently unknown, discuss inconclusive or contested results from previous studies, and emphasize the necessity to improve or build on previous research​.

Creating a rationale is a vital part of the research process, as it not only sets the stage for your study but also convinces readers of the value and necessity of your work.

How to Write a Rationale:

Writing a rationale for your research is crucial in conducting and presenting your study. It involves explaining why your research is necessary and important. Here’s a guide to help you craft a compelling rationale:

Identify the Problem or Knowledge Gap: 

Begin by clearly stating the issue or gap in knowledge that your research aims to address. Explain why this problem is important and merits investigation. It is the foundation of your rationale and sets the stage for the need for your research.​

Review the Literature: 

Conduct a thorough review of existing literature on your topic. It helps you understand what research has already been done and what gaps or open questions exist. Your rationale should build on this background by highlighting these gaps and emphasizing the importance of addressing them​​​​.

Define Your Research Questions/Hypotheses: 

Based on your understanding of the problem and literature review, clearly state the research questions or hypotheses that your study aims to explore. These should logically stem from the identified gaps or issues.

Explain Your Research Approach: 

Describe the methods you will use for your research, including data collection and analysis techniques. Justify why these methods are appropriate for addressing your research questions or hypotheses​​.

Discuss the Potential Impact of Your Research:  Explain the significance of your study. Consider both theoretical contributions and practical implications. For instance, how does your research advance existing knowledge? Does it have real-world applications? Is it relevant to a specific field or community?​

Consider Ethical Considerations: 

If your research involves human or animal subjects, discuss the ethical aspects and how you plan to conduct your study responsibly​.

Contextualise Your Study: 

Justify the relevance of your research by explaining how it fits into the broader context. Connect your study to current trends, societal needs, or academic discussions​​.

Support with Evidence: 

Provide evidence or examples that underscore the need for your research. It could include citing relevant studies, statistics, or scenarios that illustrate the problem or gap your research addresses​.

Methodological, Contextual, and Conceptual Limitations: 

Address any limitations of previous research and how your study aims to overcome them. It can include methodological flaws in previous studies, changes in external factors that make past research less relevant, or the need to study a phenomenon within a new conceptual framework​.

Placement in Your Paper: 

Typically, the rationale is written toward the end of the introduction section of your paper, providing a logical lead-in to your research questions and methodology​​.

By following these steps and considering your audience’s perspective, you can write a strong and compelling rationale that clearly communicates the significance and necessity of your research project.

Frequently Asked Questions:

What makes a good research rationale.

A good rationale clearly identifies a gap in existing knowledge, builds on previous research, and outlines why your study is necessary and significant.

How detailed should my literature review be in the rationale?

Your literature review should be comprehensive enough to highlight the gaps your research aims to fill, but it should not overshadow the rationale itself.

Conclusion: 

A well-crafted rationale is your ticket to making your research stand out. It’s about bridging gaps, challenging norms, and paving the way for new discoveries. So go ahead, make your rationale the cornerstone of your research narrative!

Up until working with Casey, we had only had poor to mediocre experiences outsourcing work to agencies. Casey & the team at CJ&CO are the exception to the rule.

Communication was beyond great, his understanding of our vision was phenomenal, and instead of needing babysitting like the other agencies we worked with, he was not only completely dependable but also gave us sound suggestions on how to get better results, at the risk of us not needing him for the initial job we requested (absolute gem).

This has truly been the first time we worked with someone outside of our business that quickly grasped our vision, and that I could completely forget about and would still deliver above expectations.

I honestly can't wait to work in many more projects together!

How to Write the Rationale of the Study in Research (Examples)

research gap and rationale

What is the Rationale of the Study?

The rationale of the study is the justification for taking on a given study. It explains the reason the study was conducted or should be conducted. This means the study rationale should explain to the reader or examiner why the study is/was necessary. It is also sometimes called the “purpose” or “justification” of a study. While this is not difficult to grasp in itself, you might wonder how the rationale of the study is different from your research question or from the statement of the problem of your study, and how it fits into the rest of your thesis or research paper. 

The rationale of the study links the background of the study to your specific research question and justifies the need for the latter on the basis of the former. In brief, you first provide and discuss existing data on the topic, and then you tell the reader, based on the background evidence you just presented, where you identified gaps or issues and why you think it is important to address those. The problem statement, lastly, is the formulation of the specific research question you choose to investigate, following logically from your rationale, and the approach you are planning to use to do that.

Table of Contents:

How to write a rationale for a research paper , how do you justify the need for a research study.

  • Study Rationale Example: Where Does It Go In Your Paper?

The basis for writing a research rationale is preliminary data or a clear description of an observation. If you are doing basic/theoretical research, then a literature review will help you identify gaps in current knowledge. In applied/practical research, you base your rationale on an existing issue with a certain process (e.g., vaccine proof registration) or practice (e.g., patient treatment) that is well documented and needs to be addressed. By presenting the reader with earlier evidence or observations, you can (and have to) convince them that you are not just repeating what other people have already done or said and that your ideas are not coming out of thin air. 

Once you have explained where you are coming from, you should justify the need for doing additional research–this is essentially the rationale of your study. Finally, when you have convinced the reader of the purpose of your work, you can end your introduction section with the statement of the problem of your research that contains clear aims and objectives and also briefly describes (and justifies) your methodological approach. 

When is the Rationale for Research Written?

The author can present the study rationale both before and after the research is conducted. 

  • Before conducting research : The study rationale is a central component of the research proposal . It represents the plan of your work, constructed before the study is actually executed.
  • Once research has been conducted : After the study is completed, the rationale is presented in a research article or  PhD dissertation  to explain why you focused on this specific research question. When writing the study rationale for this purpose, the author should link the rationale of the research to the aims and outcomes of the study.

What to Include in the Study Rationale

Although every study rationale is different and discusses different specific elements of a study’s method or approach, there are some elements that should be included to write a good rationale. Make sure to touch on the following:

  • A summary of conclusions from your review of the relevant literature
  • What is currently unknown (gaps in knowledge)
  • Inconclusive or contested results  from previous studies on the same or similar topic
  • The necessity to improve or build on previous research, such as to improve methodology or utilize newer techniques and/or technologies

There are different types of limitations that you can use to justify the need for your study. In applied/practical research, the justification for investigating something is always that an existing process/practice has a problem or is not satisfactory. Let’s say, for example, that people in a certain country/city/community commonly complain about hospital care on weekends (not enough staff, not enough attention, no decisions being made), but you looked into it and realized that nobody ever investigated whether these perceived problems are actually based on objective shortages/non-availabilities of care or whether the lower numbers of patients who are treated during weekends are commensurate with the provided services.

In this case, “lack of data” is your justification for digging deeper into the problem. Or, if it is obvious that there is a shortage of staff and provided services on weekends, you could decide to investigate which of the usual procedures are skipped during weekends as a result and what the negative consequences are. 

In basic/theoretical research, lack of knowledge is of course a common and accepted justification for additional research—but make sure that it is not your only motivation. “Nobody has ever done this” is only a convincing reason for a study if you explain to the reader why you think we should know more about this specific phenomenon. If there is earlier research but you think it has limitations, then those can usually be classified into “methodological”, “contextual”, and “conceptual” limitations. To identify such limitations, you can ask specific questions and let those questions guide you when you explain to the reader why your study was necessary:

Methodological limitations

  • Did earlier studies try but failed to measure/identify a specific phenomenon?
  • Was earlier research based on incorrect conceptualizations of variables?
  • Were earlier studies based on questionable operationalizations of key concepts?
  • Did earlier studies use questionable or inappropriate research designs?

Contextual limitations

  • Have recent changes in the studied problem made previous studies irrelevant?
  • Are you studying a new/particular context that previous findings do not apply to?

Conceptual limitations

  • Do previous findings only make sense within a specific framework or ideology?

Study Rationale Examples

Let’s look at an example from one of our earlier articles on the statement of the problem to clarify how your rationale fits into your introduction section. This is a very short introduction for a practical research study on the challenges of online learning. Your introduction might be much longer (especially the context/background section), and this example does not contain any sources (which you will have to provide for all claims you make and all earlier studies you cite)—but please pay attention to how the background presentation , rationale, and problem statement blend into each other in a logical way so that the reader can follow and has no reason to question your motivation or the foundation of your research.

Background presentation

Since the beginning of the Covid pandemic, most educational institutions around the world have transitioned to a fully online study model, at least during peak times of infections and social distancing measures. This transition has not been easy and even two years into the pandemic, problems with online teaching and studying persist (reference needed) . 

While the increasing gap between those with access to technology and equipment and those without access has been determined to be one of the main challenges (reference needed) , others claim that online learning offers more opportunities for many students by breaking down barriers of location and distance (reference needed) .  

Rationale of the study

Since teachers and students cannot wait for circumstances to go back to normal, the measures that schools and universities have implemented during the last two years, their advantages and disadvantages, and the impact of those measures on students’ progress, satisfaction, and well-being need to be understood so that improvements can be made and demographics that have been left behind can receive the support they need as soon as possible.

Statement of the problem

To identify what changes in the learning environment were considered the most challenging and how those changes relate to a variety of student outcome measures, we conducted surveys and interviews among teachers and students at ten institutions of higher education in four different major cities, two in the US (New York and Chicago), one in South Korea (Seoul), and one in the UK (London). Responses were analyzed with a focus on different student demographics and how they might have been affected differently by the current situation.

How long is a study rationale?

In a research article bound for journal publication, your rationale should not be longer than a few sentences (no longer than one brief paragraph). A  dissertation or thesis  usually allows for a longer description; depending on the length and nature of your document, this could be up to a couple of paragraphs in length. A completely novel or unconventional approach might warrant a longer and more detailed justification than an approach that slightly deviates from well-established methods and approaches.

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.

What is a ‘gap in the literature’?

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

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

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

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

How do you identify the gaps?

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

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

Identifying a Gap in the Literature - Dr. Laurie Bedford

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

Literature Gap & Future Research - Library Workshop

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

Where can you locate research gaps?

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

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

Roadrunner Search

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

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

  • Charlesworth Author Services
  • 19 November, 2021

The rationale for one’s research is the justification for undertaking a given study. It states the reason(s) why a researcher chooses to focus on the topic in question, including what the significance is and what gaps the research intends to fill. In short, it is an explanation that rationalises the need for the study. The rationale is typically followed by a hypothesis/ research question (s) and the study objectives.

When is the rationale for research written?

The rationale of a study can be presented both before and after the research is conducted. 

  • Before : The rationale is a crucial part of your research proposal , representing the plan of your work as formulated before you execute your study.
  • After : Once the study is completed, the rationale is presented in a research paper or dissertation to explain why you focused on the particular question. In this instance, you would link the rationale of your research project to the study aims and outcomes.

Basis for writing the research rationale

The study rationale is predominantly based on preliminary data . A literature review will help you identify gaps in the current knowledge base and also ensure that you avoid duplicating what has already been done. You can then formulate the justification for your study from the existing literature on the subject and the perceived outcomes of the proposed study.

Length of the research rationale

In a research proposal or research article, the rationale would not take up more than a few sentences . A thesis or dissertation would allow for a longer description, which could even run into a couple of paragraphs . The length might even depend on the field of study or nature of the experiment. For instance, a completely novel or unconventional approach might warrant a longer and more detailed justification.

Basic elements of the research rationale

Every research rationale should include some mention or discussion of the following: 

  • An overview of your conclusions from your literature review
  • Gaps in current knowledge
  • Inconclusive or controversial findings from previous studies
  • The need to build on previous research (e.g. unanswered questions, the need to update concepts in light of new findings and/or new technical advancements). 

Example of a research rationale

Note: This uses a fictional study.

Abc xyz is a newly identified microalgal species isolated from fish tanks. While Abc xyz algal blooms have been seen as a threat to pisciculture, some studies have hinted at their unusually high carotenoid content and unique carotenoid profile. Carotenoid profiling has been carried out only in a handful of microalgal species from this genus, and the search for microalgae rich in bioactive carotenoids has not yielded promising candidates so far. This in-depth examination of the carotenoid profile of Abc xyz will help identify and quantify novel and potentially useful carotenoids from an untapped aquaculture resource .

In conclusion

It is important to describe the rationale of your research in order to put the significance and novelty of your specific research project into perspective. Once you have successfully articulated the reason(s) for your research, you will have convinced readers of the importance of your work!

Research-Methodology

Rationale for the Study

It is important for you to be able to explain the importance of the research you are conducting by providing valid arguments. Rationale for the study, also referred to as justification for the study, is reason why you have conducted your study in the first place. This part in your paper needs to explain uniqueness and importance of your research. Rationale for the study needs to be specific and ideally, it should relate to the following points:

1. The research needs to contribute to the elimination of a gap in the literature. Elimination of gap in the present literature is one of the compulsory requirements for your study. In other words, you don’t need to ‘re-invent the wheel’ and your research aims and objectives need to focus on new topics. For example, you can choose to conduct an empirical study to assess the implications of COVID-19 pandemic on the numbers of tourists visitors in your city. This might be previously undressed topic, taking into account that COVID-19 pandemic is a relatively recent phenomenon.

Alternatively, if you cannot find a new topic to research, you can attempt to offer fresh perspectives on existing management, business or economic issues. For example, while thousands of studies have been previously conducted to study various aspects of leadership, this topic as far from being exhausted as a research area. Specifically, new studies can be conducted in the area of leadership to analyze the impacts of new communication mediums such as TikTok, and other social networking sites on leadership practices.

You can also discuss the shortcomings of previous works devoted to your research area. Shortcomings in previous studies can be divided into three groups:

a) Methodological limitations . Methodology employed in previous study may be flawed in terms of research design, research approach or sampling.

b) Contextual limitations . Relevance of previous works may be non-existent for the present because external factors have changed.

c) Conceptual limitations . Previous studies may be unjustifiably bound up to a particular model or an ideology.

While discussing the shortcomings of previous studies you should explain how you are going to correct them. This principle is true to almost all areas in business studies i.e. gaps or shortcomings in the literature can be found in relation to almost all areas of business and economics.

2. The research can be conducted to solve a specific problem. It helps if you can explain why you are the right person and in the right position to solve the problem. You have to explain the essence of the problem in a detailed manner and highlight practical benefits associated with the solution of the problem. Suppose, your dissertation topic is “a study into advantages and disadvantages of various entry strategies into Chinese market”. In this case, you can say that practical implications of your research relates to assisting businesses aiming to enter Chinese market to do more informed decision making.

Alternatively, if your research is devoted to the analysis of impacts of CSR programs and initiatives on brand image, practical contributions of your study would relate to contributing to the level of effectiveness of CSR programs of businesses.

Additional examples of studies that can assist to address specific practical problems may include the following:

  • A study into the reasons of high employee turnover at Hanson Brick
  • A critical analysis of employee motivation problems at Esporta, Finchley Road, London
  • A research into effective succession planning at Microsoft
  • A study into major differences between private and public primary education in the USA and implications of these differences on the quality of education

However, it is important to note that it is not an obligatory for a dissertation   to be associated with the solution of a specific problem. Dissertations can be purely theory-based as well. Examples of such studies include the following:

  • Born or bred: revising The Great Man theory of leadership in the 21 st century
  • A critical analysis of the relevance of McClelland’s Achievement theory to the US information technology industry
  • Neoliberalism as a major reason behind the emergence of the global financial and economic crisis of 2007-2009
  • Analysis of Lewin’s Model of Change and its relevance to pharmaceutical sector of France

3. Your study has to contribute to the level of professional development of the researcher . That is you. You have to explain in a detailed manner in what ways your research contributes to the achievement of your long-term career aspirations.

For example, you have selected a research topic of “ A critical analysis of the relevance of McClelland’s Achievement theory in the US information technology industry ”.  You may state that you associate your career aspirations with becoming an IT executive in the US, and accordingly, in-depth knowledge of employee motivation in this industry is going to contribute your chances of success in your chosen career path.

Therefore, you are in a better position if you have already identified your career objectives, so that during the research process you can get detailed knowledge about various aspects of your chosen industry.

Q: How to build the rationale of the study if there is no research gap?

I have seen that its important to do a literature search to find the research gap (what has not been done). So, how I will build the rationale of my study if I find so many previous studies that have already been done?

Asked on 07 Nov, 2019

Put emphasis on the fact that your replicating previous studies which is important for your research area.

You are adding to the body of evidence and you could comment on why you think this is important.

research gap and rationale

Perhaps consider providing extensive background detail on the context and built a case for the need to replicate the study. This will also pave the way to adding new to the knowledge that is unique to your context a s not visible in the previous study. 

Another place could be to use alternative research approach (if possible) to see if change in approach may lead to different learning on the construct/ topic.

Structured Abstract

Research objective:.

Systematic reviews, in addition to summarizing the evidence, generally also discuss needs for future research. However, in contrast to the methods of the systematic review, future needs are not identified systematically. There is limited literature describing organizing principles or frameworks for determining research gaps. We developed and pilot-tested a framework for the identification of research gaps from systematic reviews.

Study Design:

We reviewed the research gaps identification practices of organizations involved with evidence synthesis. We contacted: (i) evidence-based practice centers (EPCs) (n=12) associated with the Agency for Healthcare Research and Quality ( AHRQ ) in the US and Canada, and (ii) other organizations around the world (n=64) that conduct systematic reviews, cost-effectiveness analyses, or technology assessments. Based on the responses, we developed a framework for identifying research gaps. We obtained feedback from two technical experts at our institution and pilot-tested this framework on two randomly selected EPC evidence reports. We also developed a simple, user-friendly worksheet with instructions to facilitate the use of the framework by investigators during or after a systematic review.

Population Studied:

Not Applicable.

Principal Findings:

Four (33.3%) EPCs and 3 (8.1%) of the other organizations reported currently using an explicit framework to determine research gaps. We did not identify one framework that captured all elements needed to determine and characterize research gaps. Variations of the PICO (population, intervention, comparison, outcomes) framework were most common. It is also important to classify the reason(s) for the gap to help determine how to address the gap. Therefore, we propose a framework that includes both the characterization of the gap using PICOS elements (also including setting) and the identification of the reason(s) why the gap exists. The framework allows investigators to classify reasons for the existence of a research gap as: (a) insufficient or imprecise information, (b) biased information; (c) inconsistency or unknown consistency, and (d) not the right information. We mapped each of these reasons to concepts from three commonly used evidence grading systems: the Grading of Recommendations Assessment, Development and Evaluation ( GRADE ); the United States Preventive Services Task Force ( USPSTF ); and the Strength of Evidence (SOE) used by EPCs. This allows leveraging of work already being completed during evidence grading. During pilot-testing, we identified challenges including difficulty in applying the framework for completed systematic reviews and differences in the specificity of research gaps abstracted by different users. These could be tackled with a priori discussions amongst investigators. Further testing should determine if these challenges are ameliorated if the framework is used during a systematic review.

Conclusions:

We developed a framework to identify and characterize research gaps from systematic reviews. The framework provides for the classification of where and why the current evidence falls short.

Implications for Policy, Delivery, or Practice:

In synthesizing evidence, systematic reviews inform health-care decisions for patients, policymakers, and clinicians. Systematic reviews can also be invaluable for identifying research gaps, thus helping develop research agendas. This potential impact of systematic reviews has not been realized. Our framework provides for systematically identifying and characterizing research gaps from systematic reviews. This explicit identification of research gaps will help determine the type of research needed to address the goals of comparative effectiveness research.

  1. What Is A Research Gap (With Examples)

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

  2. How to Write the Rationale for a Research Paper

    The rationale for your research is the reason why you decided to conduct the study in the first place. The motivation for asking the question. The knowledge gap. This is often the most significant part of your publication. It justifies the study's purpose, novelty, and significance for science or society.

  3. How to write the rationale for research?| Editage Insights

    To write your rationale, you should first write a background on what all research has been done on your study topic. Follow this with 'what is missing' or 'what are the open questions of the study'. Identify the gaps in the literature and emphasize why it is important to address those gaps. This will form the rationale of your study.

  13. How to Write a Rationale: A Guide for Research and Beyond

    What is a Rationale? A rationale in research is essentially the foundation of your study. It serves as the justification for undertaking a particular research project. At its core, the rationale explains why the research was conducted or needs to be conducted, thus addressing a specific knowledge gap or research question.

  14. How to Write the Rationale of the Study in Research (Examples)

    The rationale of the study is the justification for taking on a given study. It explains the reason the study was conducted or should be conducted. This means the study rationale should explain to the reader or examiner why the study is/was necessary. It is also sometimes called the "purpose" or "justification" of a study.

  15. The gap statement and justification in higher education research: an

    Claiming a gap in the literature is the preferred rhetorical device for articulating a rationale for a study in higher education research. Explicit gap statements, which are easier to identify in the text, were a minority, and thus a careful reading was required for identifying implicit gap state-ments.

Sometimes you'll find a research gap if all the existing research is outdated and in need of new/updated research ...

  18. Literature Gap and Future Research

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

  19. How to write the rationale for your research

    The rationale for one's research is the justification for undertaking a given study. It states the reason (s) why a researcher chooses to focus on the topic in question, including what the significance is and what gaps the research intends to fill. In short, it is an explanation that rationalises the need for the study.

  20. Rationale for the Study

    Rationale for the study needs to be specific and ideally, it should relate to the following points: 1. The research needs to contribute to the elimination of a gap in the literature. Elimination of gap in the present literature is one of the compulsory requirements for your study. In other words, you don't need to 're-invent the wheel ...
