Summary of Groupthink. Abstract

Irving Janis (1972)

Irving Janis developed a study on group decision making based on human social behavior in which maintaining group cohesiveness and solidarity is felt as more important than considering the facts in a realistic manner. Janis gave the following definition of Groupthink (GT):

A mode of thinking that people engage in when they are deeply involved in a cohesive group, when the members' strivings for unanimity override their motivation to realistically appraise alternative courses of action.

GT is a result of cohesiveness in groups, already discussed by Lewin in the 1930s and is an important factor to consider in decision processes, such as workshops, meetings, conferences, committees, etc.

Certain conditions are conducive to Groupthink, such as:

The following negative outcomes of GT are possible:

  1. The group limits its discussion to only a few alternatives.
  2. The solution initially favored by most members is never restudied to seek out less obvious pitfalls
  3. The group fails to reexamine those alternatives originally disfavored by the majority.
  4. Expert opinion is not sought
  5. The group is highly selective in gathering and attending to available information
  6. The group is so confident in its ideas that it does not consider contingency plans.

A few methods to prevent Groupthink are:

What are typical symptoms of GT?
Janis listed eight symptoms that show that concurrence seeking has led the group astray.

The first two stem from overconfidence in the group’s powers. The next pair reflect the tunnel vision members use to view the problem.

The final four are signs of strong conformity pressure within the group.

  1. Illusion of Invulnerability: Janis summarizes this attitude as ‘‘everything is going to work out all right because we are a special group." Examining few alternatives.
  2. Belief in Inherent Morality of the Group: under the sway of GT, members automatically assume the rightness of their cause.
  3. Collective Rationalization: a collective mindset of being rational. Being highly selective in gathering information.
  4. Out-group Stereotypes
  5. Self-Censorship: people only offer equivocal or tempered opinions. Not seeking expert or outside opinions. Pressure to conform within group; members withhold criticisms.
  6. Illusion of Unanimity. Individual group members look to each other to confirm theories.
  7. Direct Pressure on Dissenters. Pressure to protect group from negative views or information.
  8. Self-Appointed Mindguards: these ‘‘mindguards" protect a leader from assault by troublesome ideas.
