This study examined if Social Dominance Orientation (SDO) might differ depending on the outgroup with which one's own group is compared. SDO was divided into two factors: “Group-based dominance” and “Equality.” We predicted that Group-based dominance would be high when one's own is compared with a relatively low status outgroup, whereas Equality would be high when one's own group was compared with a relatively high status outgroup. Furthermore, we predicted that this tendency would be apparent in members whose intragroup status was close to the outgroup. University students participated in an experiment that manipulated intergroup status by changing the outgroup status, and its effect on SDO, as well as intragroup status was examined. Results of Study 1 indicated no effect of intergroup and intragroup status on SDO. However in Study 2, by improving the SDO scale, we obtained results that supported our predictions. That is, Group-based dominance scores of low intragroup status members increased when compared with a low status group, whereas Equality scores of high intragroup status members increased when compared with a high status group.
