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.

新成员是团体中创新观点的重要来源。然而，新人的想法可能很难被听到。具有高（相对于低）关闭需求（NFC）水平的群体成员可能更抵制新人的创新想法。此外，当群体认知权威 (EA) 较高时，成员应该“冻结”群体的想法，而不管新成员的 EA。相反，当组 EA 较低时，成员将被期望“抓住”具有高 EA 的新人提出的想法。研究 1 证实，高（与低）NFC 组成员对新来者的创新想法更抗拒。在研究 2 中，在高 NFC 组中，获得了扣押而不是冻结的证据。在研究 3 中，对于 NFC 升高的组成员，获得了冻结和扣押结果。
