A Brief Review of Research that Questions the Impact of Questionable Research Practices

This is the authors' abstract. We don't add key points for this paper.

Research on questionable research practices (QRPs) includes a growing body of work that questions whether they are as problematic as commonly assumed. This article provides a brief and selective review that considers some of this work. In particular, the review highlights work that questions the prevalence and impact of QRPs, including p-hacking, HARKing, and publication bias. According to this work, QRPs may not provide the best explanation for the replication crisis, and they may not always be problematic. In particular, p-hacking, HARKing, and publication bias may be less impactful than expected.
