• Groupthink is a phenomenon in which people lose sight of potential problems in the pursuit of consensus thinking.

  • Any dissenters in the group who might try to present a rational argument are pressured into reaching a consensus and may even be censored.
  • Groupthink is especially dangerous in political situations where no one participant has all the necessary information.
  • Groupthink can be reduced by drawing criticism or appointing one person as “devil’s advocate” against the group.
  • The Challenger shuttle disaster, the Bay of Pigs, Watergate, and the escalation of the Vietnam War are all considered possible consequences of groupthink.
