The Open Science Collaboration, a consortium of 270 scientists, attempted to replicate 100 published psychology studies and found that more than half of the replications failed.
Notes on verification
Confirmed by multiple independent sources including Science magazine, the Center for Open Science's own press release, APA's Monitor, and the Association of Research Libraries. Numbers (270 scientists, 100 studies, majority failed) are consistent across sources, though some nuance exists regarding statistical interpretation of 'failure'.
