When groupthink occurs in highly cohesive groups, poor decisions may result from the members' tendencies to do all of the following EXCEPT:

A) being unwilling to criticize one another's ideas and suggestions.
B) underemphasizing agreement.
C) desiring to hold the group together.
D) underemphasizing critical discussion.
E) seeking to avoid unpleasant circumstances.

Groupthink occurs when highly cohesive groups make poor decisions because members prioritize agreement and maintaining harmony over critical discussion and input. Therefore, all of the answer choices except for underemphasizing agreement contribute to groupthink. Underemphasizing agreement means that the group is not giving enough importance to finding common ground, and this is not a characteristic of groupthink.
