Motivated team innovation: Impact of need for closure and epistemic authority

New members are important sources of innovative perspectives in groups. However, it can be very difficult for newcomers’ ideas to be heard. It is likely that group members with high (vs. low) levels of need for closure (NFC) are more resistant to newcomers’ innovative ideas. Moreover, when group epistemic authority (EA) is high, members should “freeze” on the group’s ideas, regardless of the newcomer’s EA. In contrast, when group EA is low, members would be expected to “seize” the ideas proposed by newcomers with high EA. Study 1 confirmed that high (vs. low) NFC group members are more resistant to newcomers’ innovative ideas. In Study 2, in high NFC groups, evidence was obtained for seizing but not freezing. In Study 3, for group members with heightened NFC, both freezing and seizing results were obtained. Findings suggest that both NFC and EA play important roles in receptivity to newcomers’ ideas.
