Groupthink

A social‑psychological syndrome in which highly cohesive decision groups prioritize unanimity and conformity over critical appraisal, characterized by symptoms such as self‑censorship, illusion of unanimity, direct pressure on dissenters, stereotyped out‑group views, and insulation from external information; these process failures increase the risk of flawed or risky collective decisions.

A group-decision phenomenon in which motivations for consensus, cohesion, or conformity suppress critical examination and dissent, producing flawed assessments, limited consideration of alternatives, and decisions that underestimate risks or ignore contradictory information.
