Abstract
Do social groups that have a strong ideological basis tend to form a cohesive group identity among group members? This paper investigates how negatively defining an out-group is important, if not integral, for creating a shared identity among members of ideologically based social groups. To explore this connection, I interviewed undergraduate student members of a Christian club and an atheist club at a Midwestern research university. I examined the strength of group identification, how members revealed shared identity, and patterns regarding how participants characterize out-group members. My findings suggest that atheists characterized Christians as less rational and in need of external comfort more than themselves, whereas Christians described atheists as disturbed by suffering and the behavior of some self-identified Christians. Defining one’s in-group and reaffirming the correctness and inherent social benefit of the in-group’s views were essential components of out-group characterizations.
