This study tests whether the detrimental effects of strong diversity faultlines on team performance can be counteracted by combining 2 managerial strategies: task role crosscutting and superordinate goals. We conducted a 2 (crosscut vs. aligned roles) × 2 (superordinate vs. subgroup goals) experimental study. Seventy-two 4-person teams with faultlines stemming from gender and educational major performed a complex decision-making task. The results show that teams with crosscut roles perform better when they are assigned a superordinate goal than a subgroup goal, whereas teams with aligned roles are not affected by goal manipulations. This effect is mediated by elaboration of task-relevant information. Implications for theory and management of team faultlines are discussed.
