Reviewing over 20 years of faultlines research, we conducted a meta-analysis based on 168 studies from 162 papers with a sample size of 24,953 teams. Dormant faultlines are positively and significantly related to conflict and activated faultlines, but contrary to widespread beliefs, not directly related to team performance or team satisfaction. Further, the negative effects of dormant faultlines hinge on their activation; activated faultlines mediate the relationship between dormant faultlines on the one hand, and conflict, information elaboration, team performance, and team satisfaction on the other. However, when controlling for the effect of activated faultlines, there are positive effects of dormant faultlines on information elaboration. The relationship between dormant faultlines and activated faultlines was more pronounced when dormant faultlines were based on demographic attributes. Additionally, dormant faultlines were negatively related to team performance when teams were not top management or board teams and when studies were conducted in labs. We synthesize these results to provide a robust agenda for future research on team faultlines.

断层线文献的元分析整合

我们回顾了 20 多年的断层线研究，基于 162 篇论文中的 168 项研究，样本量为 24,953 个团队，进行了荟萃分析。休眠断层线与冲突和激活断层线呈显着正相关，但与普遍看法相反，它与团队绩效或团队满意度没有直接关系。此外，休眠断层线的负面影响取决于它们的激活。激活的断层线一方面调节休眠断层线之间的关系，另一方面调节冲突、信息阐述、团队绩效和团队满意度。然而，当控制激活断层线的影响时，休眠断层线对信息阐述有积极的影响。当休眠断层线基于人口统计属性时，休眠断层线和激活断层线之间的关系更加明显。此外，当团队不是高层管理人员或董事会团队以及在实验室进行研究时，休眠断层线与团队绩效呈负相关。我们综合这些结果，为未来的团队断层研究提供一个强有力的议程。
