What We Learned from Trying to Reproduce Psychological Science

Over the past two years, I4R has collaborated with Psychological Science, a leading journal in psychology, on a large reproducibility project. 67 independent teams completed reproduction reports for 64 articles published in the journal in 2024 and 2025. That covers about 44% of the 146 eligible articles from those two years. Teams followed a standardized protocol specified by I4R. They documented data and code availability, computational reproducibility, coding errors, prevalence of preregistration, deviations from preregistered plans, and whether those deviations were acknowledged.

The Correlated Referee

If every journal (or any committee that makes a decision) screens work with the same AI, the reviewers stop being independent, and independence was the point.
