Symptoms of Group-think

A simpler definition of group-think come from wiki books. Group-think is a process where members of a group start thinking alike and there are less individual ideas and creativity. The symptoms of group-think are:

• Illusion of invulnerability: Members are extremely optimistic and believe what ever they do will be a success. Usually occurs with group leaders who have multiple successes.
• Collective rationalization: All members come to the same conclusion, they put aside warning signs and refuse to reconsider any assumptions. 
• Belief in inherent morality: Members take actions based on the rightness of their cause and ignore ethical or moral consequences. Usually prevalent with cults, terrorist groups, and some governments. 
• Stereotyped views of out-groups: A negative view of the 'enemy', creates an us vs. them culture. This view makes a reasonable response to conflict unnecessary for the members in this group.
•  Direct pressure on dissenters: Members are pressured to suppress negative or argumentative opinions of the group.
• Self-censorship: Members hold back their own doubts and deviations, there is no expression of consensus.
• Illusion of unanimity: The decision or view of the majority is assumed to be unanimous.
• Self-appointed mind-guards: Members guard one another or the leader from information that might be problematic.
