1. Group polarization(group shift):

Member’s attitudes and opinions with respect to an issue or a solution may change during group discussion. Some studies of this tendency may change during group discussion. Some have showed the change to be a fairly consistent movement towards a more risky solution, called “risky shift”. Other studies and analysis have revealed that the group induced shift is not always towards more risk. Again, the group is just as likely to move towards more risk.

Group polarization occurs when the average of the group members’ post-discussion attitudes tends to be more extreme than average pre-discussion attitudes.
