In the Reproducibility Project, original study authors reviewed the materials and methods used by replication teams to help reproduce the original experiments as closely as possible.
Notes on verification
Confirmed by the original Open Science Collaboration 2015 Science paper, university press release, BPS Research Digest, and follow-up academic literature (Ebersole et al. 2020). Process was largely as described, though nuanced—most but not all replications were endorsed after author review. [tier=gold indep_score=0.963 clusters=4 claim_tier=notable]
