The purpose of this study was to explore the expectation that, in conversations between unacquainted men and women, men would disclose more than women and would create a positive impression in so doing. In 8-min, relatively unstructured conversations, both men and women (N=301) perceived themselves and their partners as disclosing approximately the same amount. For both sexes, the more their partners disclosed, the more favorably they rated their partners on social attractiveness and positive attributes. Moreover, both sexes believed that the more they disclosed themselves, the more positively their partners evaluated them. However, the strength of this relationship was significantly stronger for men than for women. Neither sex conformed to the expectation that men should disclose more, but both may have believed to some extent that their partners were evaluating them in accord with this expectation.
