Only 39 of the 100 psychology studies examined in the Reproducibility Project were successfully replicated.
Notes on verification
Confirmed by the original 2015 Science paper (Open Science Collaboration) and corroborated by PNAS, Futurism, APA Monitor, and other secondary sources. Minor metric variation exists (39% subjective rating vs 36% statistical significance), but the claim matches the commonly cited figure. [tier=gold indep_score=0.983 clusters=3 claim_tier=notable]
