Editing Group polarization (section)

===Social comparison theory===
The [[social comparison theory]], or normative influence theory, has been widely used to explain group polarization. According to the social comparison interpretation, group polarization occurs as a result of individuals' desire to gain acceptance and be perceived in a favorable way by their group. The theory holds that people first compare their own ideas with those held by the rest of the group; they observe and evaluate what the group values and prefers. In order to gain acceptance, people then take a position that is similar to everyone else's but slightly more extreme. In doing so, individuals support the group's beliefs while still presenting themselves as admirable group "leaders". The presence of a member with an extreme viewpoint or attitude does not further polarize the group.<ref name=[23]>{{cite journal|last=Van Swol|first=Lyn M.|title=Extreme members and group polarization|journal=Social Influence|year=2009|volume=4|issue=3|pages=185–199|doi=10.1080/15534510802584368|s2cid=219697757}}</ref> Studies regarding the theory have demonstrated that normative influence is more likely with judgmental issues, a group goal of harmony, person-oriented group members, and public responses.<ref name="Isenberg_group polarization"/>
