Every research idea depends on things being true, available, measurable, or feasible that the study may not directly test. Making those assumptions explicit can reveal which ones are harmless working premises and which could undermine the entire project.
Read Guide →If the relationship you expect does not appear, your study has not automatically failed. The important question is whether the evidence meaningfully challenges the expected relationship or whether the study remains too uncertain to tell.
Read Guide →A worthwhile study should not depend entirely on producing the result you hope to find. Before collecting data, ask what would actually be learned if the main relationship, difference, or effect turns out to be null.
Read Guide →Recruiting fewer participants than expected can affect far more than your sample-size target. Determine what lower recruitment means for precision, representation, timelines, resources, and whether the study can still answer its research question.
Read Guide →Having data is not the same as having data capable of answering your research question. If the data turn out to be incomplete, inaccurate, inconsistent, poorly measured, or otherwise unsuitable, determine what can be repaired, what requires a narrower claim, and what makes the study no longer viable.
Read Guide →Losing access to your preferred method does not automatically mean losing the research idea. Return to the research question, identify what evidence the original method was supposed to provide, and determine whether another defensible approach can still produce the answer you need.
Read Guide →Research does not become unnecessary merely because you expect the same result as previous studies. The real question is whether another study would meaningfully increase confidence, precision, generalizability, theoretical understanding, or the usefulness of the existing evidence.
Read Guide →The study you first imagine is not necessarily the best way to answer your research question. Compare alternative designs by the evidence they can produce, the assumptions they require, and the time, participants, data, and resources they consume.
Read Guide →A more complicated study is not necessarily a better study. Ask whether a simpler design could answer the consequential part of your research question with credible evidence.
Read Guide →Before collecting new data, check whether an existing dataset can answer your question more efficiently or even more convincingly. The important test is whether the data fit the question, not merely whether they are available.
Read Guide →An expected finding can often arise through more than one process. Identifying plausible alternative explanations before collecting data can sharpen your research question, strengthen the design, and prevent an association from being interpreted too quickly.
Read Guide →A plausible explanation can help organize a study, but committing to it too early may quietly shape the question, variables, and design around confirming it. Stronger research ideas keep credible alternatives visible long enough to test what the evidence can actually distinguish.
Read Guide →An association between X and Y does not tell you whether X causes Y, Y causes X, or both processes occur. Reverse causation should be considered whenever the proposed outcome could plausibly influence the proposed exposure.
Read Guide →A finding is more informative when it favors one plausible explanation over another rather than merely fitting several of them. Strong research ideas often seek evidence on which competing explanations make different predictions, although not every worthwhile study must resolve every rival.
Read Guide →A study does not need to eliminate every plausible explanation to be worthwhile. Its value depends on what question it can answer, how much uncertainty it reduces, and whether its claims remain within the limits of the design.
Read Guide →Research does not need to eliminate uncertainty to be useful, but it should reduce the uncertainty that matters. Before collecting data, ask what will become meaningfully clearer if the study produces the evidence it is realistically capable of producing.
Read Guide →A study tests competing explanations well when those explanations predict meaningfully different observations. If every plausible result can be accommodated by every explanation, collecting more data may leave the theoretical dispute unchanged.
Read Guide →Research becomes decision-relevant when plausible findings could change which action is preferred. Before conducting a study, identify the decision, the alternatives, and what evidence could actually alter the choice.
Read Guide →A strong study should not have only one interpretable outcome. Before collecting data, examine whether the major plausible results would support defensible conclusions and identify outcomes that the design would leave genuinely unresolved.
Read Guide →If the most likely outcome of a proposed study would leave the central question unresolved, that is a reason to reconsider the design before collecting data. Redesign does not always mean increasing the sample size; sometimes the research question, comparison, measurement, or entire strategy needs to change.
Read Guide →An expensive study is not automatically unjustified. The problem arises when its expected contribution is too small to warrant the money, time, participant burden, infrastructure, and opportunities that conducting it would consume.
Read Guide →A valuable question does not justify unlimited research risk. A study becomes difficult to justify when its foreseeable risks and burdens are disproportionate to the value and reliability of the knowledge it is likely to produce.
Read Guide →An important research question may still be beyond what a particular study can answer reliably. The key is recognizing when available methods, data, measurements, samples, or designs cannot support the conclusion you want to make.
Read Guide →A worthwhile research question does not have to be studied immediately. When current constraints would produce evidence too weak to answer it reliably, postponing the study may preserve the question for a more informative opportunity.
Read Guide →A promising research idea becomes a viable project only when you can explain how it will actually be carried out. Learn how to turn your question into an aligned, feasible research plan.
