8 main symptoms of groupthink:

1. Illusion of Invulnerability: Members ignore obvious danger, take extreme risk, and are overly optimistic.

2. Collective Rationalization: Members discredit and explain away warning contrary to group thinking.

3. Illusion of Morality: Members believe their decisions are morally correct, ignoring the ethical consequences of their decisions.

4. Excessive Stereotyping:The group constructs negative sterotypes of rivals outside the group.

5. Pressure for Conformity: Members pressure any in the group who express arguments against the group’s stereotypes, illusions, or commitments, viewing such opposition as disloyalty.

6. Self-Censorship: Members withhold their dissenting views and counter-arguments.

7. Illusion of Unanimity: Members perceive falsely that everyone agrees with the group’s decision; silence is seen as consent.

8. Mindguards: Some members appoint themselves to the role of protecting the group from adverse information that might threaten group complacency.


In my time within YWAM and a spiritually abusive church, I encountered all of these put forth by Irving Janis in  Decision making: A psychological analysis of conflict, choice, and commitment.

Any thoughts?
