All Questionable Research Practices

Ways of analyzing or reporting data that produce misleading results, including p-hacking and hypothesizing after the results are known. A phenomenon belongs here when its cited article describes such a practice. Every member sits in the Psychology Atlas as its own page with a definition, cited sources and links to related effects, so the group works as a reading path through Questionable Research Practices rather than as a claim that the members share one cause. Where scholars disagree about how an effect should be classified, the member page says so.
