Interactions Within Groups and Subgroups: The Effects of Demographic Faultlines
通过实地实验研究，发现人口统计学断层线比单一属性异质性指标更能解释团队学习、心理安全等感知差异，且弱断层线群体中跨子群体沟通有效，强断层线群体中则无效。
We investigated the effects of intragroup and cross-subgroup communications in an experimental field study on demographic faultlines. The results indicated that faultlines explained more variance in perceptions of team learning, psychological safety, satisfaction, and expected performance than single-attribute heterogeneity indexes. In addition, cross-subgroup work communications were effective for groups with weak faultlines but not for groups with strong faultlines. Overall, this study extends the original faultline model, documents the utility of the concept of faultlines, and identifies some of their effects on work group outcomes.
