What is a Knowledge Gap?
A knowledge gap refers to an area or question within a research topic that has not been sufficiently studied or understood. Identifying knowledge gaps helps researchers pinpoint opportunities for original and valuable contributions.
Why Identifying Knowledge Gaps Matters
Recognising gaps in literature ensures your study builds on existing knowledge rather than repeating it. It also strengthens your research justification and relevance.
How to Identify a Knowledge Gap
- Review recent research articles and meta-analyses.
- Look for inconsistencies, unanswered questions, or underrepresented populations.
- Note areas where authors suggest future research directions.
Examples of Knowledge Gaps
- Lack of studies on a specific demographic or region.
- Limited evidence supporting a particular theory.
- Unexplored relationships between two key variables.
Best Practices
- Read broadly and critically across multiple databases.
- Use literature mapping to visualise what has been studied and what hasn’t.
- Formulate your research question directly around the identified gap.
