Abstract
Although the concept of groupthink (the extreme concurrence‐seeking tendency displayed by decision making groups), has been an influential one, empirical research has provided equivocal support for the groupthink model. In this paper, we review previous case and laboratory work on groupthink and identify empirical and theoretical inconsistencies. We then describe a model of groupthink as social identity maintenance (SIM) that is capable of reconciling these inconsistencies and summarize laboratory experiments that specifically test the SIM hypothesis. We use the model to suggest possible pitfalls of previous proposals for preventing groupthink when SIM pressures are operative. Finally, we suggest intervention strategies capable of mitigating groupthink due to SIM that have two objectives: (a) the reduction of pressures toward identity protection and (b) the stimulation of intellectual conflict.
