Short communication The big consequences of small biases: A simulation of peer review

Abstract

When total review bias exceeds 1.9% of grant score, statistically significant variation in scores between PC and NPC investigators is discernable in a pool of 2000 grant applications. When total review bias exceeds 2.8% of total grant score, statistically significant discrepancies in funding rates between PC and NPC investigators are detectable in a simulation of grant review.
