Two studies examined how the gender of a workplace supervisor can affect a woman's response to performance evaluations and also her professional advancement aspirations. In Study 1, employed women reviewed a performance evaluation in which feedback was manipulated to reflect one of two stereotypes of women (high in warmth or low in competence). Findings showed that participants were more likely to attribute negative (i.e., low competence) feedback from men supervisors to gender biases than the same feedback from women supervisors. There was no effect of supervisor gender when the feedback was positive (i.e., high warmth) or neutral. In Study 2, negative feedback from men supervisors, regardless of evaluative dimension (competence or warmth) resulted in women reporting decreased professional aspirations. This relationship was mediated by women's attribution of supervisor feedback to gender biases. Together, these findings suggest that same‐gender supervisors can potentially buffer women's long term professional aspirations after a discouraging performance review.
