✨ ERROR (@error.reviews) is a bug-bounty program for science that seeks to estimate the prevalence and nature of errors. error.reviews

The full rationale, including the review and author response, are available on PsyArXiv: osf.io/preprints/ps.... The study materials and all new materials generated as part of the review are on OSF: osf.io/abyqs/. Original article available here: journals.sagepub.com/doi/10.1177/....

We are very grateful to @erichehman.bsky.social and colleagues for their participation in this project. This serves to help improve our culture around scientific error, and is a testament to their commitment to scientific values of transparency and verification.

A reformulated regression model that accounts for base rates more effectively finds no significant relationship between Black/White Racial Prejudice IAT scores and police killings of Black people. We recommend the authors seek a correction.

The error review found that Hehman et al. (2018) did contain a major error that affects a core conclusion. Specifically, the use of a difference of proportions variable as the regression outcome did not effectively adjust for the Black population base rate.
