Which antecedents and group processes are beneficial to creativity in groups? Taking a component-based approach of individualism–collectivism (I-C), we proposed that the combination of collectivistic value orientation and independent self-representation of group members enhances group creativity. In an interactive group brainstorming experiment (N = 68 triads), we manipulated group members’ value orientation and their self-representation via priming methods and examined group creativity using both a consensual and an objective measure of idea originality. Results indicated that groups generated ideas that are more original when members combined a collectivistic value orientation with independent self-representation than with interdependent self-representation. In contrast, differences in self-representation did not have a significant effect when an individualistic value orientation was activated. We also identified specific group processes characteristic of the predicted combinatorial effect: In creative groups, there was more open communication. Implications of these findings for research on group creativity and future directions are discussed.
