Economics replication probe finds fabricated PNAS football paper data, Codex used to audit

- I4Replication's replicators investigated a PNAS paper on elite footballers and initially missed the bigger story, until an independent researcher showed the data was likely fabricated.
- Economist Paul Novosad shares the thread, noting fabricated results are everywhere and it is now easy to pull these threads—suggesting having Codex download all replication packages from the authors and plot the data distributions to audit at scale.
