A model of thought in which people who are deeply involved in a cohesive group value the maintenance of group solidarity over a realistic appraisal of facts. Individual doubts are set aside, and the group may end up making hasty, irrational decisions.
Example: In the film and play “Twelve Angry Men”, eleven of the twelve jurors hastily decide to condemn the defendant in their case to death without thoroughly questioning the facts.
