Exercise 22

S ometimes groups make extreme decisions-decisions that are either more risky or more conservative than they would have been if individuals acting alone had made them. One explanation for the tendency of groups to make extreme decisions is diffusion of responsibility. In a group, responsibility for the outcomes of a decision is spread among group members, so each person feels less than fully accountable. The group's decision is extreme because no individual has taken full responsibility for it.
When group decision making takes place, should members of a group each feel fully accountable for outcomes of the decision? Why or why not?
