Not every answerable research question deserves a study. A worthwhile question should justify the time, resources, risks, and attention required by the value of the knowledge it is likely to produce.
Read Guide →More research is not automatically better research. Existing evidence may already be sufficient when additional studies are unlikely to reduce consequential uncertainty or change a reasonable conclusion or decision.
Read Guide →A study does not automatically become necessary because nobody has conducted it in your city, university, province, or country. Local research is most useful when the new setting creates a meaningful uncertainty that existing evidence cannot adequately resolve.
Read Guide →Studying a new population can strengthen an evidence base, but population novelty is not automatically scientific novelty. The key question is whether the new population changes what can be inferred, tested, represented, or decided.
Read Guide →Adding another variable does not automatically make a study more sophisticated or original. A new variable earns its place when it helps answer the research question, distinguish explanations, improve inference, or resolve uncertainty that matters.
Read Guide →A fashionable topic can contain important unanswered questions, but popularity is not evidence of research value. Study the question when consequential uncertainty remains, not merely because the topic currently attracts attention.
Read Guide →A research idea is ready to move into study design when it is clear enough to specify what needs to be learned, why the question matters, what evidence could answer it, and whether obtaining that evidence appears realistically possible. You do not need every methodological detail yet, but you need enough conceptual stability for design decisions to become meaningful.
Read Guide →A promising research idea is not automatically ready for study design. Before proceeding, test whether the problem, question, contribution, evidence needs, and practical conditions are sufficiently defensible.
Read Guide →A research problem can be genuine without being important enough to justify another study. Evaluate what would change if the problem were better understood and whether that knowledge warrants the cost of obtaining it.
Read Guide →A study does not need to be unprecedented to make a worthwhile contribution. The stronger question is whether the evidence it produces would add something meaningfully distinct to what researchers can already know, explain, test, or decide.
Read Guide →Before defending a proposed study, try to make the strongest evidence-based case for not doing it. Serious objections can expose weak assumptions, unnecessary research, poor feasibility, or a better way to answer the question.
Read Guide →Uncertainty does not need to reach zero before further research becomes unnecessary. Before collecting new data, ask whether existing evidence already supports the relevant conclusion or decision well enough.
Read Guide →Time already spent on a research idea cannot make the next year of work worthwhile. Reassess the project using what you know now and decide whether its remaining costs are justified by its remaining scientific value.
Read Guide →Forget for a moment that the proposal, literature review, instruments, or preliminary work already exist. If you were choosing among research ideas today using everything you now know, would this still be the one you select?
Read Guide →A convincing research justification should survive one deceptively simple question: why does this particular study need to exist? The answer requires more than novelty, a literature gap, or an interesting topic.
Read Guide →A literature search is not simply an exercise in finding as many papers as possible. Its purpose depends on what you need the literature to help you understand, decide, or establish in your research.
Read Guide →You usually need some engagement with the literature before finalizing a research question, but you do not necessarily need a complete literature review first. In many studies, searching, reading, and question development proceed iteratively.
Read Guide →Starting broad can help when you are still learning a research area, while a focused question becomes increasingly important when you need to identify a defined body of evidence. The most useful approach is often progressive focusing rather than choosing one strategy for the entire project.
Read Guide →A literature search can legitimately change your research question when it reveals better terminology, existing evidence, conceptual problems, feasibility constraints, or a more meaningful problem. The key is to distinguish evidence-informed refinement from arbitrary or outcome-driven changes.
Read Guide →A good literature search should leave you with more than a collection of papers. You should be able to explain what the literature supports, where findings differ, how the evidence was produced, what remains uncertain, and why those uncertainties matter.
Read Guide →Knowing many papers gives you familiarity with individual studies. Understanding a literature means you can explain how those studies relate, where evidence converges or conflicts, what methods shape the findings, and what remains uncertain.
Read Guide →A thesis or dissertation needs a defensibly thorough literature search, not an impossible search for every publication. Learn what adequate coverage looks like and when you can reasonably stop searching.
Read Guide →A journal article needs enough literature searching to support its claims and position its contribution accurately, but not every article requires an exhaustive search. The appropriate depth depends on what the paper is trying to establish.
Read Guide →Before designing a new study, search far enough to understand what is already known and how previous researchers investigated the problem. The goal is not exhaustive retrieval but preventing avoidable design errors and unnecessary research.
Read Guide →A grant proposal needs enough literature searching to establish why the proposed research matters, whether it is needed, and whether its scientific foundation is credible. Strong proposals assess the relevant prior evidence rather than merely collecting citations that support the project.
