Why preregister research?

By preregistering research, you create a public record of your hypotheses and planned analyses before you conduct them, so that you can later demonstrate that you did not change hypotheses after learning your results (HARKing; Kerr, 1998), nor that you changed the analysis to create a specific result. This increases the credibility of your findings, and is increasingly becoming the standard in our field.

Questionable research practices

Preregistration is all about proving that we don't engage in questionable research practices (QRPs).

Preregistration as a solution

Registered reports

Registered reports are a special case of preregistration, where the study plan is peer-reviewed as part of the publication process. They merit their own entry.
