Eight Main Symptoms of Group Think

Janis, I. L. & Mann, L. (1977). Decision making: psychological analysis of conflicts, choices and promises. New York: Freedom News. )

1. Invincible hallucinations: members ignore obvious dangers, take extreme risks, are too optimistic

2. Group rationalization: Members crush and explain warnings on collective thinking

3. Moral Illusion: Members think their decision is morally correct, ignoring the moral impact of resolution.

5. Pressure of compliance: Members put pressure on someone in the group, they oppose the group's stereotypes, fantasies or pledges and treat such opposition as affair

7. Consistent Fantasy: Members mistakenly believe that everyone agrees to the group's decision, silence is considered consent

8. Defenders: Some members appoint their roles to protect the group from adverse information potentially threatening the dissatisfaction of the group.

2. Leaders should be neutral when assigning decision tasks to groups, taking into account all preferences and expectations first. This is particularly effective if the leader always encourages open survey atmosphere.

Leaders should emphasize opposition and doubt and accept criticism

4. The group should always consider an unwelcome alternative and assign the devil defender 's role to several powerful members of the group.

5. In evaluating feasibility, it may be useful to separate the group into two separate deliberating bodies.

7. After deciding to reach a preliminary agreement, you should express all remaining doubts and rethink the problem.

10. The organization should periodically follow the administrative convention of establishing several independent decision-making groups to address the same important issues and policies.

Group thinking has 8 symptoms. The first symptom is to make a decision that could be dangerous when everyone or most people regard themselves as invincible. This group has great confidence and authority in decision making and its own rights. They think they are better than any other group in all respects. The second indication is that the group believes that they are moral and upright, which leads the group to ignore the moral or moral result of the decision. The team overrated the ethics. There is no doubt that the group did not do the right thing, they just acted. Ignoring any information or warnings that may lead to past policy changes is the third symptom. Even though there is much evidence against their views, they think their plans are fine.

In this training video we use a drama based on historical example to simulate the eight symptoms of group thought. These symptoms include perfect hallucinations, beliefs about the collective inherent morality, rationalization, external group stereotypes, self-censorship, direct pressure, conservative thought and consistent illusions. Recognizing collective thinking can help leaders to avoid yielding to this by nurturing an open environment, avoiding isolation, encouraging valued valuations, and avoiding excessive guidance . Employees recognizing group thinking can make their team make a great decision in the encouraging atmosphere.

It is clear that the jury agreed because they had all eight symptoms of the group sacrificed. The illusion that the first symptom of the organization is satisfactory. At the beginning of the movie, all the juries did not care that the defendant was executed. In fact, the owner of the garage and the owner of the messenger service seem to think that it is very fair to think that the boy is supposed to be killed. The first point Henry Fonda tried to interrupt his work was the fact that the boy was going to be killed. He puts other jurors in the position of defendant and uses a considerate strategy to remind the children.
