Primes

• Escalation of Commitment

  • This sourceHoughton Mifflin, Boston. Defines and diagnoses groupthink through foreign-policy fiascoes (Bay of Pigs, Vietnam escalation, Pearl Harbor) where cohesive groups suppressed dissent. Bibliography-only (tier C) — not cited in the body; existence-verified and linked. ISBN 978-0-395-14002-4.

• Groupthink
  • Irving Janis (1972, 1982) articulated the canonical model with four linked components: (1) antecedent conditions — high group cohesion, structural insulation from outside views, directive or closed leadership, member homogeneity, and situational stress (especially external threat) create the conditions; (2) concurrence-seeking tendency — under these conditions, members prioritize the premature consensus and harmony over accurate assessment of alternatives and evidence; (3) eight characteristic symptoms — illusion of invulnerability (excessive optimism about group immunity to risk), collective rationalization (group collectively explains away disconfirming evidence), belief in inherent group morality (group members see themselves as ethically superior), stereotyped views of out-groups (opponents are perceived as uniformly hostile or unreasoning), the dissent suppression through direct pressure on dissenters who raise concerns, self-censorship of doubts to maintain the appearance of unanimity, the illusion of unanimity (members mistake silence for consensus), and emergence of the mindguard role where some members protect the group from contradictory information; and (4) defective decision outcomes — incomplete survey of alternatives, failure to examine risks of preferred option, poor information search, selective bias in processing evidence, failure to reappraise rejected alternatives, failure to work out contingency plans.
• Herding Behavior
  • This is often efficient; it is also a herding trigger — Janis (1972) called the pathological extreme groupthink, where committee members suppress private doubts in deference to apparent consensus and the aggregate conclusion reflects early signals more than individual independent assessments.

    This sourceDefines and diagnoses groupthink through analysis of foreign-policy fiascoes (Bay of Pigs, Vietnam escalation) where cohesive groups suppressed dissent into uniform poor decisions.

Mechanisms

• Facilitated Alignment Session
  • Its signature failure is groupthink: the drive for cohesion suppresses doubts, dissent goes unspoken

    This sourceDescribes how concurrence seeking can suppress expressed doubts and produce self-censorship and an appearance of unanimous agreement.

• Grievance Panel
  • This is groupthink, where the drive for consensus overrides realistic appraisal of the evidence.

    This sourceDefines groupthink as concurrence-seeking that displaces critical appraisal.

• Institutional Review Gate
  • Convened bodies are prone to groupthink

    This sourceIdentifies groupthink as a process in decision-making bodies driven by agreement for agreement's sake.
