Group polarization is the tendency of people to make decisions that are more extreme when they are in a group, as opposed to a decision made alone or independently. Study of this effect has shown that after participating in a discussion group, members tend to advocate more extreme positions and call for riskier courses of action than individuals who did not participate in any such discussion. This phenomenon was originally coined risky shift but was found to apply to more than risk, so the replacement term choice shift has been suggested
