Groupthink is a type of thought exhibited by group members who try to minimize conflict and reach consensus without critically testing, analyzing, and evaluating ideas. During Groupthink, members of the group avoid promoting viewpoints outside the comfort zone of consensus thinking. A variety of motives for this may exist such as a desire to avoid being seen as foolish, or a desire to avoid embarrassing or angering other members of the group. Groupthink may cause groups to make hasty, irrational decisions, where individual doubts are set aside, for fear of upsetting the group’s balance. The term is usually used as a derogatory term after the results of a bad decision.

Groupthink being a coinage – and, admittedly, a loaded one – a working definition is in order. We are not talking about mere instinctive conformity – it is, after all, a perennial failing of mankind. What we are talking about is a rationalized conformity – an open, articulate philosophy which holds that group values are not only expedient but right and good as well.

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

The word groupthink was intended to be reminiscent of Newspeak words such as “doublethink” and “duckspeak.

 Causes of groupthink

* Highly cohesive groups are much more likely to engage in groupthink. The closer they are, the less likely they are to raise questions to break the cohesion.

* The group isolates itself from outside experts. In order to make a well informed decision, the group needs to invite qualified experts to help weigh the possible risks.

* Strong leadership leads to groupthink, because the leader is more likely to promote his/her own solution.

Social psychologist Clark McCauley’s three conditions under which groupthink occurs:

* Directive leadership.

* Homogeneity of members’ social background and ideology.

* Isolation of the group from outside sources of information and analysis.

 Symptoms of groupthink

eight symptoms that are indicative of groupthink :

1. A feeling of invulnerability creates excessive optimism and encourages risk taking.

2. Discounting warnings that might challenge assumptions.

3. An unquestioned belief in the group’s morality, causing members to ignore the consequences of their actions.

4. Stereotyped views of enemy leaders.

5. Pressure to conform against members of the group who disagree.

6. Shutting down of ideas that deviate from the apparent group consensus.

7. An illusion of unanimity with regards to going along with the group.

8. Mindguards – self-appointed members who shield the group from dissenting opinions.

 Classic case of groupthink

Bay of Pigs invasion (1959-1962)

Another closely-studied case of groupthink is the 1961 Bay of Pigs invasion . The main idea of the Bay of Pigs invasion was to train a group of Cuban exiles to invade Cuba and spark a revolution against Fidel Castro’s communist regime.

The plan was fatally flawed from the beginning, but none of President Kennedy’s top advisers spoke out against the plan. Kennedy’s advisers also had the main characteristics of groupthink: They had all been educated in the country’s top universities, causing them to become a very cohesive group. They were also all afraid of speaking out against the plan, because they did not want to upset the president. The President’s brother, Robert Kennedy, took on the role of a “mind guard”, telling dissenters that it was a waste of their time, because the President had already made up his mind.

 Preventing groupthink

seven ways of preventing groupthink :

1. Leaders should assign each member the role of “critical evaluator”. This allows each member to freely air objections and doubts.

2. Higher-ups should not express an opinion when assigning a task to a group.

3. The organization should set up several independent groups, working on the same problem.

4. All effective alternatives should be examined.

5. Each member should discuss the group’s ideas with trusted people outside of the group.

6. The group should invite outside experts into meetings. Group members should be allowed to discuss with and question the outside experts.

7. At least one group member should be assigned the role of Devil’s advocate. This should be a different person for each meeting.

By following these guidelines, groupthink can be avoided. After the Bay of Pigs fiasco, John F. Kennedy sought to avoid groupthink during the Cuban Missile Crisis. During meetings, he invited outside experts to share their viewpoints, and allowed group members to question them carefully. He also encouraged group members to discuss possible solutions with trusted members within their separate departments, and he even divided the group up into various sub-groups, in order to partially break the group cohesion. JFK was deliberately absent from the meetings, so as to avoid pressing his own opinion. Ultimately, the Cuban missile crisis was resolved peacefully, thanks in part to these measures.


There has been much criticism about the groupthink theory. Robert S. Baron contends that recent investigation and testing has not been able to defend the connection between certain antecedents with groupthink . This may simply be due to the fact that the groupthink theory is very difficult to test in a lab situation using a scientific method. Alfinger and Esser also came to the same conclusion . After ending their study, they stated that better methods of testing Janis’ symptoms were needed. It is impossible to create in labs the same conditions under which important government groups work. It is impossible to create the same levels of stress and pressure experienced by high level government officials, with the future of the entire nation hanging in the balance. Baron also contends that the groupthink model applies to a far wider range of groups than Janis originally concluded. This remains to be tested. However, it can be speculated that many people who have worked in a group setting can identify some of the symptoms of groupthink.
