Mass Reproducibility in Psychological Science

Under review at Psychological Science, 2026

Conducted in partnership between Psychological Science and the Institute for Replication, this large-scale initiative examines the reproducibility of empirical findings published in the journal during 2024 and 2025. Sixty-seven independent teams assessed 64 articles, covering data and code availability, coding and reporting issues, deviations from preregistration, and computational reproducibility.

The project finds that 58.2% of the examined articles are fully reproducible from final analysis data, compared with 28.4% from raw data. Teams identified coding errors or statistical reporting inconsistencies in 63% of the articles, although most issues were minor. Rene Schwaiger is one of the contributing co-authors in this international collaboration.
