Groupthink is a psychological phenomenon which occurs when a group is under the pressure for unanimity. In the case when a group’s need for consensus exceeds the individuality of group members, a situation of group think takes place. The term groupthink was designed by social psychologist Irving Janis the year 1972. Groups affected by groupthink focus on harmony or conformity in the group which more often than not, results in illogical and dysfunctional decision making.
It leads to deterioration of moral judgment, individuality, creativity and mental efficiency. It often occurs in situations when the focus is on completing a task, mainly due to time constraints; in such cases, individuals allow any one group member to take the lead in decision making, putting aside their judgements and opinions. Groupthink also occurs when workflow processes do not appreciate or accommodate change; or when one is under social pressure to agree with the majority.
