Also known as the group polarisation effect, this refers to the tendency among groups to assume positions that are far more extreme than the initial positions of the individual members of the group following a group discussion. Increased interaction between like-minded individuals can cause groups as a whole to assume more extreme positions. Such polarisation, however, may not happen when the group consists of individuals with vastly different view points. A group of liberals, for instance, may assume an extreme liberal position after a discussion. The same may not happen in a group that consists of both liberals and conservatives.
