The tendency for a group decision to be riskier than the average decision made by the individual group members is known as

A) risk hedging.
B) social loafing.
C) risky shift.
D) group polarization.

The risky shift is a phenomenon where individuals in a group tend to make riskier decisions than they would have made on their own. This occurs because people in groups often feel less personally accountable and more likely to take risks when they perceive that the group as a whole is supportive of risky decisions. Group polarization, on the other hand, refers to the tendency for groups to make more extreme decisions than average, regardless of whether those decisions are risky or cautious. Risk hedging involves making decisions that reduce the overall risk of a particular action or outcome, while social loafing refers to the tendency for individuals to work less hard in a group setting than they would on their own.
