It's performance review season, so women be aware that we tend to be harder on ourselves than men.

" In every setting we explored, we observed a substantial gender gap in self-promotion: Women systematically provided less favorable assessments of their own past performance and potential future ability than equally performing men. And our various study versions revealed that this gender gap was not driven by confidence or by strategic incentives and that it was robust both in the face of ambiguity and under increased transparency."
