SO5005 Chap.2 Literature Gaps, Questions and Proposals
Literature Gaps, Questions and Proposals
Synthesise rather than list
A literature review groups studies around claims, compares populations, measurements and designs, and states what the evidence collectively establishes. The gap is a justified uncertainty, not merely the absence of a local paper.
It may concern an excluded population, weak measurement, an unresolved mechanism or a design unable to establish temporal order.
Keep the proposal aligned
The background, literature gap, research question, significance and methodology should name the same construct. Originality comes from resolving an uncertainty that matters.
A method chosen before the question often produces a polished proposal that cannot answer its own problem.

Literature Gaps, Questions and Proposals FAQ
How is synthesis different from summary?
Summary reports what each paper says. Synthesis organises papers around a question, compares why their findings agree or differ and states what the body of evidence supports. It is the bridge from published work to the proposal's literature gap.
Is a missing local study automatically a gap?
Not by itself. The proposal should explain why evidence may not transfer, such as a different population, care pathway, measurement or mechanism. If the earlier result should transfer without difficulty, repeating it in a new postcode adds little originality.
How narrow should a research question be?
It should specify a feasible population, phenomenon or variables and the kind of answer sought. Narrowing is useful when it lets the design recruit credibly, measure the intended construct and complete a defensible analysis within available time and resources.
Assessment move
For each source, write one line for its claim, design, population and limitation. Then group sources by the claim they address rather than by author. End each group with the uncertainty that remains and test whether your proposed question resolves that exact uncertainty. Use a synthesis matrix rather than drafting from highlighted articles.
Put the review's claims in rows and the studies in columns, then record population, measurement, design and result only where they help compare evidence. Empty cells often expose the real gap more clearly than a paragraph of summaries.
Draft each review paragraph from the row: open with the collective claim, explain the strongest agreement, locate the important difference and close with what the group of studies still cannot answer. Remove author-by-author openings after the first draft. On a separate page, write four one-sentence statements: problem, established knowledge, unresolved uncertainty and research question. Underline the main construct in each.
If the underlined words change, decide whether the proposal has discovered a better question or merely drifted. Test originality by asking what decision or interpretation would change if the question were answered. A new setting is useful only when transfer is uncertain for a stated reason. Rehearse proposal compression by explaining the chain aloud in ninety seconds without method jargon.
A listener should hear why the study is necessary before hearing how it will be conducted. Finally, audit the seven published criteria as connections: background to objectives, review to gap, gap to question, question to significance, and significance to methodology. Presentation and readability should make those links easier to inspect rather than conceal missing logic behind polished formatting.
Build a reverse outline after drafting: write the job of each paragraph in the margin and remove any paragraph that neither establishes knowledge, identifies uncertainty nor justifies a choice. Check every citation for the claim it supports and avoid attaching several sources to a sentence that none directly addresses.
Create a gap test by writing the opposite conclusion; if existing evidence already rules it out, the proposed gap may be artificial. Rehearse answering three marker questions: why this population, why this outcome and why this design. Each answer should point back to the synthesis rather than convenience. End with an abstract-sized version of the proposal so the chain can be checked without section headings.
Give that version to a reader unfamiliar with the topic and ask them to identify the gap and proposed contribution. Their answer tests whether the logic is genuinely visible rather than obvious only to the author. Revise any point they misidentify before polishing sentences. Logic takes priority over elegance. Evidence always controls the prose and the proposed method.
