The claim that there is a gender confidence gap-women have lower self- confidence than men-identifies a critical issue for women in the workplace. What has yet to be explored is the possibility that communicating this issue creates a new stereotype threat that may negatively affect women’s performance. We examined the effect of a series of messages on stereotype threat and performance that were both consistent with and contradicting the gender confidence gap, as well as implicitly and explicitly comparing women and men. In Study 1, women perceived more stereotype threat than men after reading implicit messages consistent with the gender confidence gap. In Study 2, women performed better than men on a verbal task after reading the opposite message-women have higher confidence than men or that men have low confidence. A counter intuitive finding in Study 2 showed that despite having higher stereotype threat than women, men performed better than women in a numeric task given the message that women have higher confidence than men. These results suggest that gendered messages have differential consequences for men and women in their performance of sex-typed tasks.
