Effect of Threat and Social Identity on Reactions to Ingroup Criticism: Defensiveness, Openness, and a Remedy.

Openness to criticism and dissenting opinions is enormously important to group decision-making. Past research has found that people are more persuaded by criticism of their group when it comes from fellow ingroup members rather than outgroup members. But this ingroup advantage is not boundless. Three experiments demonstrate that the ingroup advantage related to openness to criticism is erased when perceivers feel their group is under threat. The results further suggest that the psychological mechanism underlying defensive responses to criticism is attributional-Threat elicits greater suspicion of ingroup critics' motives, which eliminates the ingroup critic's advantage relative to outgroup critics. A final experiment tests an intervention designed to increase openness to criticism and finds that reminders of the importance of dissent and free speech emerge as an effective remedy to increase the persuasiveness of criticism despite high threat.
