Across 37,073 European Research Council applications, the same proposal scored higher with reviewers who shared the applicant’s citizenship and country of work — and that match moved the score about seven times as much as a shared gender did
Two economists contracted by the ERC's own executive agency compared how a single proposal was scored by reviewers who matched the applicant and reviewers who did not. Sharing both citizenship and country of work moved the first-stage project score by 0.164 of a point on a five-point scale. The link to actual funding decisions is weaker, and correlational.
