Equal Performance, Different Grade: Women's Performance in Discussion Perceived Worse Than Men's.

We investigate how men and women are evaluated in group discussions. In five studies ( = 761) using a variant of a , we find that, when experimentally and/or statistically controlling for gender differences in behavior, the female performance in a group discussion is devalued in comparison to male performance. This was observed for fellow group members (Study 1) and outside observers (Studies 2-5), in both primarily student (Studies 1, 4, and 5) and mixed samples (Studies 2 and 3), for different measures of performance (perceived helpfulness of the contribution, for work-related competence), across different discussion formats (preformulated chat messages, open chat), and when controlling for the number of female group members (Study 5).
