Group Polarization

Social Biases and Group Effects

In social psychology, group polarization refers to the tendency for a group to reach decisions that are more extreme than the initial inclinations of its individual members, shifting toward greater risk when members initially lean toward risk and toward greater caution when they initially lean toward caution. The phenomenon also holds for attitudes rather than just decisions: a group's initial attitude toward a situation tends to strengthen and intensify after group discussion, a related effect known as attitude polarization.
