Why does groupthink occur? Think about the last time you were part of a group, perhaps during a school project. Imagine that someone proposes an idea that you think is quite poor. However, everyone else in the group agrees with the person who suggested the idea and the group seems set on pursuing that course of action. Do you voice your dissent or do you just go along with the majority opinion? In many cases, people end up engaging in groupthink when they fear that their objections might disrupt the harmony of the group or suspect that their ideas might cause other members to reject them.
