COS Metascience and Research

COS conducts research on research practices to understand areas of inefficiency, and to evaluate interventions to improve. See more of our studies here.

Replication Project: Cancer Biology

RP:CB is a collaboration between COS and Science Exchange to conduct direct replications of 50 high-impact cancer biology studies. Learn more.

SCORE: Systematizing Confidence in Open Research and Evidence
