A research gap, often referred to as a “gap in the literature” or “research vacuum,” is a specific area within a field of study or research where existing knowledge and research have not adequately addressed a particular question, problem, or issue. It represents a void or deficiency in the current understanding of a subject. Identifying and addressing research gaps is a fundamental part of advancing knowledge and conducting meaningful research.
Research gaps can take various forms, including:
Unanswered Questions: There may be specific questions related to a topic that have not been thoroughly investigated or remain unanswered by existing research.
Contradictory Findings: When existing studies produce conflicting or inconsistent results, it can indicate a research gap that needs resolution and further investigation.
Incomplete or Outdated Research: Some areas may have outdated or incomplete research due to evolving technologies, changes in society, or new developments in a field. Research gaps can arise when older studies no longer address contemporary issues adequately.
Emerging Trends and Issues: As new trends, technologies, or issues emerge, there may be limited research available to provide insights into these developments. This creates opportunities to explore uncharted territory.
Regional or Contextual Gaps: Research gaps can also manifest based on geographic or contextual variations. A topic well-researched in one context may be relatively unexplored in another.
Unexplored Methodologies: Some research gaps may involve a lack of studies using specific research methodologies or approaches, providing opportunities for innovation.
To identify a research gap, researchers conduct a comprehensive review of the existing literature in their field, looking for areas where the current research falls short or new knowledge is needed. Here’s a step-by-step guide to help you identify a research gap for your dissertation:
Review the literature
Start by conducting a comprehensive review of the existing literature in your field. This will help you understand what has already been researched, what the current state of knowledge is, and where potential gaps might exist. As you review the literature, look for common themes, trends, and areas of consensus. Pay attention to recurring questions, problems, or unresolved issues that researchers have addressed.

Analyze existing research
Consider the methodologies, theories, and approaches that previous researchers have used. Are there limitations to their methods or unanswered questions that their research has raised? Identify areas where you believe the existing research may be incomplete or where new perspectives are needed.
Seek out contradictions and inconsistencies
Sometimes, contradictions or inconsistencies in the literature can be a strong indicator of a research gap. If different studies yield conflicting results or interpretations, it may signal a need for further investigation or clarification.
Review areas of future research
In the conclusion section of a research paper, the writer will likely identify areas of potential future research. These may arise from the weaknesses of their research study or a particular finding. For example, a researcher who used quantitative research may suggest that the same question be applied to a qualitative research study.
