Institute for
Replication
Improving the credibility of science by systematically reproducing and replicating important empirical research in the social sciences.
What We Do
Three pillars driving credibility in empirical research
Games & Events
We organize replication games worldwide, bringing together researchers to reproduce and replicate influential studies in economics and social sciences.
Discussion Papers
Our growing collection of 232+ discussion papers documents reproduction and replication attempts, contributing to a transparent scientific record.
Replication Tools
We develop and curate tools that help researchers verify, reproduce, and build upon existing empirical work more efficiently.

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. Here is what we learned.

How can we link publications to replications and generalizations? Improving the findability of replications and retractions
Science is supposed to be a self-correcting system. But how well can it correct itself if we do not know which studies have subsequently been replicated, reproduced, generalized—or failed to replicate?
