This is really good - lots of studies from I/O psychologists measuring at companies in this analysis. This makes a strong case for anonymous peer reviews in addition to the manager’s review (peer reviews are the most correlated with performance but the manager review is correlated as well.)

If I read this correctly, this correlation is despite all the drawbacks people bring up in this thread, since they would be baked into these datasets too. Seems like you would want multiple anonymous peer reviews to try and get something predictive.
