As discussed in the book (and as we will discuss in class on Monday, April 23rd), groupthink occurs when a team makes bad decisions for a series of reasons (see page 275 of the book). All of the following strategies can help prevent groupthink EXCEPT...
The leader communicating his/her preferences before the team starts discussion
Having a "devil's advocate" placed in the group to present an opinion that opposes the majority of the group.
Taking an anonymous poll of group members before discussion.
Reducing pressure on the team to make a quick decision.
