Effects of stereotypic beliefs were examined in a group problem solving context, featuring full-fledged, face-to-face interaction. Based on formal analysis of group aggregation processes, it was hypothesized that positive and negative impacts of stereotypic beliefs on task performance in problem solving were larger on the group level than on the individual level. In the present study, data from five-person groups working on a series of problem-solving tasks were used to test the hypothesis. Results indicated that stereotypic beliefs indeed exerted “emergent influence” as hypothesized on task performance in the group problem solving. The finding illustrates the importance of socially-shared aspects of stereotypic beliefs, providing a case for the need for “truly social” social-cognition research.
