It's so obvious:
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.
