Groupthink is a phenomenon that occurs when a group of well-intentioned people makes irrational or non-optimal decisions spurred by the urge to conform or the belief that dissent is impossible. The problematic or premature consensus that is characteristic of groupthink may be fueled by a particular agenda—or it may be due to group members valuing harmony and coherence above critical thought. The term "groupthink" was first introduced in the November 1971 issue of Psychology Today by psychologist Irving Janis. Janis had conducted extensive research on group decision-making under conditions of stress. Tune in and learn how group think has taken over our politics, life, education and destiny!
