Group responses to deviance: Disentangling the motivational roles of collective enhancement and self-uncertainty reduction

In this paper, we describe two basic motives for social identification: a drive for collective enhancement and a drive for epistemic fulfillment (uncertainty reduction). We posit that these two motives are critical for understanding one of the fundamental underlying mechanisms of social identity theory (SIT): positive distinctiveness, which is a desire to feel different from and better than relevant outgroups. Whereas “positive” was clearly outlined in the original social identity theory of intergroup relations, “distinctiveness” became a focal point of self-categorization theory. Most existing literature treats positive distinctiveness as a single construct; however, we argue that the “positive” and “distinctive” elements should be treated as separate but critically intertwined concepts. We suggest that “positive” is a direct feature of a desire for collective enhancement, and “distinctiveness” from a relevant outgroup is necessary for self-categorization that provides information to reduce self-uncertainty. Using the subjective group dynamics framework, which has historically emphasized the enhancement motive, we mathematically show that the motives act sequentially and differently to affect responses to deviance and change from it.
