IN-GROUP IDENTIFICATION, SOCIAL-DOMINANCE ORIENTATION, AND DIFFERENTIAL INTERGROUP SOCIAL ALLOCATION

Three varieties of differential intergroup social allocation were examined in a sample of American students as a function of degree of in-group legitimacy, self-esteem, sex, and social dominance orientation within a standard minimal-groups experimental paradigm. The results are consistent with both social identity theory and much previous research in this area: The greater the in-group identification, the greater the allocation of social value in favor of the in-group. The results are also consistent with the expectations of social dominance theory and show that, even after the effects of gender, self-esteem, and in-group identification were considered, the greater the social dominance orientation, the greater the allocation of social value in favor of the in-group. For two of the three indexes of social value, there was a statistically significant interaction between in-group identification and social dominance orientation. Subjects showing strong acceptance of their in-group classification and who had relatively high levels of social dominance orientation displayed greater in-group bias.
