A Social Identity Maintenance Model of Groupthink.

We present a social identity maintenance model of groupthink that (a) defines groupthink as a collective attempt to maintain a positive image of the group, (b) identifies conditions under which this form of concurrence seeking is likely to occur, (c) parsimoniously explains the equivocal empirical findings on groupthink, and (d) specifies intervention tactics that can mitigate the detrimental consequences of groupthink for group decision outcomes.
