Changing a research design is not inherently poor methodology. Adaptation may be defensible when it responds to a genuine problem while preserving a credible connection between the research question, the evidence being generated, and the conclusions the study will support.
Read Guide →Poor research design is not merely a technical problem when people bear burdens or risks for knowledge the study is unlikely to produce. Methodological quality can therefore become part of the ethical justification for research.
Read Guide →Vulnerability is not always something participants bring into a study. Recruitment methods, incentives, privacy practices, authority relationships, and other design choices can create or intensify vulnerabilities that might otherwise have been absent.
Read Guide →The strongest study on paper is not always the strongest study you should conduct. Learn how to distinguish necessary rigor from unnecessary ambition and design research that is both credible and realistically completable.
Read Guide →Community involvement may need to begin before a population-specific study is designed when community knowledge is necessary to define the problem, choose meaningful outcomes, develop feasible procedures, or avoid harmful assumptions. Not every study requires co-design, but consultation that arrives after all consequential decisions have been made may arrive too late.
Read Guide →A worthwhile research question does not automatically justify the first study you design around it. Compare credible alternatives and ask which approach would reduce the important uncertainty most effectively.
Read Guide →A stronger design is not simply a more complicated or prestigious design. It is one that addresses the weaknesses preventing existing evidence from supporting the specific inference your research question requires.
Read Guide →The same broad research topic can often be studied cross-sectionally or longitudinally, but the two designs do not answer exactly the same question. Changing the temporal structure changes what evidence is available and therefore what conclusions the study can support.
Read Guide →An additional time point matters when it changes the temporal pattern or competing explanation a study can examine. The methodological value comes not from having more observations, but from what the new measurement allows researchers to distinguish.
Read Guide →A statistically convincing association is not automatically a causal effect. Learn how to recognize when your design supports a relationship between variables but cannot credibly establish what would happen if one were changed.
Read Guide →Research is more than searching for information. It is a systematic and disciplined process of investigating questions, examining evidence, and developing knowledge that can withstand scrutiny.
Read Guide →Looking up reviews before buying a laptop and conducting a scientific study both involve seeking answers, but they operate under different standards. The key differences concern how questions are investigated, evidence is evaluated, and conclusions are justified.
Read Guide →Research is generally expected to contribute to knowledge, but that does not mean every study must discover something completely unprecedented. Novelty can arise through new evidence, contexts, explanations, tests, methods, interpretations, or clearer knowledge about the limits of existing claims.
Read Guide →Research does not have to pursue a completely new claim. Confirmatory and replication studies can make important contributions by testing whether existing findings withstand additional scrutiny, hold under new conditions, or require qualification.
Read Guide →Research does not have to collect new data. Existing datasets, records, archives, documents, and other previously created materials can support rigorous and original research when they are appropriate to a new research question.
Read Guide →Research does not have to involve an experiment or test a hypothesis. Experiments and hypothesis testing are powerful approaches for particular questions, but observational, exploratory, descriptive, qualitative, historical, and other forms of research may require different designs.
Read Guide →Research does not have to use statistics. Qualitative research can stand on its own when the question calls for systematic investigation of meanings, experiences, processes, practices, or contexts rather than numerical estimation.
Read Guide →There is no single sequence of scientific-method steps that every researcher must follow. Scientific inquiry uses diverse methods, but those methods remain accountable to shared principles concerning evidence, reasoning, transparency, and scrutiny.
Read Guide →Systematic research follows an organized and defensible process, while rigorous research applies appropriate methods with sufficient care to support credible conclusions. Neither requires one universal procedure.
Read Guide →Empirical research develops or evaluates knowledge through systematic engagement with observation or experience. It can be quantitative or qualitative, but not every legitimate form of scholarly research is empirical in the same sense.
Read Guide →Objectivity is an important research value, but it does not require researchers to become perspective-free observers. Strong research uses methodological safeguards, transparency, critical scrutiny, and, where appropriate, reflexivity to reduce or account for influences that could distort conclusions.
Read Guide →Anecdotes and expert opinions can be informative, but they are not equivalent to systematically produced research evidence. Their value depends on the question, while research provides methods for examining claims beyond individual experiences or authority.
Read Guide →Market research and academic research can use many of the same systematic methods. Their main differences usually concern purpose, audience, constraints, dissemination, and how the resulting knowledge is expected to be used.
Read Guide →Reading and summarizing previous studies is essential to research, but it does not automatically constitute a research study. A literature review becomes research when existing evidence is itself investigated systematically to answer a defined question using a defensible review methodology.
Read Guide →Research does not become rigorous simply by following the method most familiar in a discipline. Rigor depends more fundamentally on whether the research design fits the question and is conducted, analyzed, and reported according to appropriate standards.
