Interactions Within Groups and Subgroups: The Effects of Demographic Faultlines

We investigated the effects of intragroup and cross-subgroup communications in an experiential 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 original faultline model, documents the utility of the concept of faultlines, and identifies some of their affects on work group outcomes.
