Crowdsourced replication

A coordinated effort in which many independent laboratories or teams attempt to replicate the same set of studies under pre-specified protocols, in order to estimate field-wide replicability.

Answers are drawn from this dictionary entry and the rest of the CASRAI corpus, with a link to every source.

Answers are AI-generated from CASRAI’s own published pages and can be wrong, so check the linked sources before relying on one; your question is logged without personal data — never sold, never used to train a third-party model — to show us what CASRAI is missing, so please do not type personal or confidential details.

A many-analysts study (different design).

Editorial commentary

The Many Labs projects, the Reproducibility Project: Psychology, and the Reproducibility Project: Cancer Biology are the best-known examples. Crowdsourced replication provides estimates of replicability that are robust to single-lab idiosyncrasies, and creates open datasets useful for downstream meta-research.
