Developing a comprehensive model to understand intergroup relationship through integrating two constructs usually used to be examined discretely; self-stereotyping and stereotyping. Background. Today’s understanding of intergroup behavior is firmly grounded in concepts related to stereotypes. In literature, apparently, there are, two dominant approaches in studying stereotype’s effect on intergroup relations. The first approach focuses on the effect of dominant group’s stereotype on intergroup relation, while the second approach focuses on studying the impacts of self stereotyping on victims. Furthermore, minority groups’ self-sterotyping is considered to be derived from the dominant groups’ stereotype. As a result, the prevailing approaches are insensitive to the dynamics in self-stereotype and its implication to the intergroup relationship. In this article, it is claimed that the etiology of intergroup behavior could be better understood by considering a mutually interacting groups’ perspective. Methodology. Systematic approach of reviewing the prevailing literature pertaining to stereotyping and self-stereotyping and integrative analysis method to develop new perspective. Conclusion. Intergroup relation involves the interaction of two or more groups each of them having stereotypes regarding their own group and outgroup. Thus, in this paper, we argued that, the etiology of intergroup behavior cannot be adequately understood without employing the belief system of mutually interacting groups. Hence, we integrated self-stereotyping and other’s stereotypes and the behaviors that emerge during intergroup relations is predicted using the dynamics in the content/valence of minority group members’ self-stereotyping simultaneously with the dominant groups’ stereotype. The integration of these two approaches appears to offer the most adequate explanation for the complex nature of intergroup behavior.
