Group Think - For What It's Worth

From Irving Janis 1972

What is Groupthink?

 

Groupthink, a term coined by social psychologist Irving Janis (1972), occurs when a group makes faulty decisions because group pressures lead to a deterioration of “mental efficiency, reality testing, and moral judgment” (p. 9).  Groups affected by groupthink ignore alternatives and tend to take irrational actions that dehumanize other groups.  A group is especially vulnerable to groupthink when its members are similar in background, when the group is insulated from outside opinions, and when there are no clear rules for decision making.

Symptoms of Groupthink

 

Janis has documented eight symptoms of groupthink:

 

1. Illusion of invulnerability –Creates excessive optimism that encourages taking extreme risks.
2. Collective rationalization – Members discount warnings and do not reconsider their assumptions.
3. Belief in inherent morality – Members believe in the rightness of their cause and therefore ignore the ethical or moral consequences of their decisions.
4. Stereotyped views of out-groups – Negative views of “enemy” make effective responses to conflict seem unnecessary.
5. Direct pressure on dissenters – Members are under pressure not to express arguments against any of the group’s views.
6. Self-censorship – Doubts and deviations from the perceived group consensus are not expressed.
7. Illusion of unanimity – The majority view and judgments are assumed to be unanimous.
8. Self-appointed ‘mindguards’ – Members protect the group and the leader from information that is problematic or contradictory to the group’s cohesiveness, view, and/or decisions.
