Chickenhawk Groupthink?
by Jim Lobe
<snip>
Students of Groupthink list a number of symptoms of the phenomenon that can lead the group into disaster, among them:
believing in the group's inherent morality;
sharing stereotypes, particularly of the enemy;
examining few alternative or contingency plans for any action;
being highly selective in gathering information;
avoiding expert opinion;
protecting the group from negative views or information that would
contradict their basic assumptions;
and – having an illusion of invulnerability.
From what is now known about planning for Iraq, each of these factors obviously played a role, and they continue to inform U.S. policy not only against perceived enemies, but even against out-groups in the administration or in Congress. And, because the in-group was so small, many of these characteristics were unusually pronounced.
