[00:00:00] Speaker 1: Literature review is like a funnel. At the top of the funnel, you're broad, taking a panoramic sweep of existing studies, the state of the art, the strengths, the weaknesses, the trends, where the field is moving. As you move down this funnel, you're going to start distilling and narrowing, getting to the conclusion that ultimately, ideally, will roll out the red carpet for what you want to do next. This could be Chapter 3, Chapter 4 in your PhD. It could be the empirical research you want to justify to a grant funder, or it could just be completing by showing what the gaps are in the field and making suggestions for future directions. The two biggest mistakes I see people commonly make is they're at the wrong stage of the funnel. Maybe right now, you're already thinking about the research you want to do, you're at the bottom of the funnel, so you start trying to summarize narrow research, and there's just not enough. At the other end, you go way too broad, and you have thousands of articles, and we never see you again.

Arow Summary
A literature review should work like a funnel: start broad by surveying the field’s state of the art, strengths, weaknesses, and trends, then progressively narrow to identify specific gaps and logically justify the next research step (e.g., a thesis chapter, grant proposal, or future directions). Common mistakes are starting too narrow too early (not enough material) or staying too broad (overwhelming volume and lack of focus).

Arow Key Takeaways
  • Begin a literature review with a broad survey of the field’s current state, including trends and limitations.
  • Narrow progressively to synthesize insights and pinpoint specific gaps.
  • End by clearly motivating and justifying your proposed research as the logical next step.
  • Avoid starting too narrowly before establishing context and sufficient coverage.
  • Avoid remaining too broad, which leads to unmanageable scope and lack of direction.
