Groupthink

A mode of thinking that people engage in when they are deeply involved in a cohesive group, and when members striving for unanimity override their motivation to realistically appraise alternative courses of action; in contrast to group strength, groupthink results in mistakes and failure. Causes of groupthink include the illusion of invulnerability, belief in the inherent morality of the group, rationalization, stereotyping of out-groups, self-censorship, direct pressure, mindguards, and the illusion of unanimity.

Cohesiveness

The quality of forming a united whole, particularly in the context of group dynamics and teamwork.

Insulated Group

A group that is isolated or protected from external pressures or influences, often to maintain focus or cohesion.
