Group polarization is a means of a group to generate action. To generate a group needs to reach agreed [[SON]], and generate enough energy for action from its members. [[conservative|Conservative]] create this energy by facilitating [[group thinking]], and creating a mood of danger to the group [[FFFF]]. The feeling of danger, is usually created by bringing evidences from extreme events and groups that threatened the wale-fare of the members of the group members. These evidence, due to group thinking are unchallenged and therefore seems real and critical. This admixture of [[group thinking]] and constructing a state of need for action in face of a generated feeling of danger is producing a state of polarization.
More recently, the literature has offered contradictory findings about deliberation in enclaves. Sunstein (2006) argue that when like-minded people cluster, they often aggravate their biases, spreading falsehoods and polarizing opinions. Findings from Karpowitz et al. (2009) and Grönlund et al. (forthcoming) contradict the groupthink and polarization hypotheses of enclave deliberation since they did not find any evidence of group polarization and amplification of cognitive errors.
