Why group harmony can lead to disaster
Groupthink, a psychological trap, makes cohesive teams prioritize harmony over critical thinking, leading to suppressed dissent and potentially disastrous decisions.
Groupthink is a fascinating psychological trap where cohesive teams prioritize agreement over critical thinking. Coined by Irving Janis, this phenomenon causes individuals to suppress doubts and dismiss contrary evidence, often leading to poor decisions. For example, President Kennedy's advisors, a tight-knit group, approved the flawed Bay of Pigs invasion despite reservations. Similarly, NASA managers overlooked warnings about O-ring failures before the Challenger disaster due to group pressure. Understanding groupthink reveals how the natural desire for unity can blindside even experts, highlighting the importance of diverse viewpoints and structured debates to avert costly errors.
