TY - JOUR AU1 - Sibley, Chris G. AU2 - Robertson, Andrew AU3 - Wilson, Marc S. AB - The additive and interactive effects of Social Dominance Orientation (SDO) and Right‐Wing Authoritarianism (RWA) were examined using 16 independent samples of New Zealand European participants (N = 2,164). Consistent with Duckitt's (2001) Dual Process Model, SDO and RWA displayed strong additive effects across various domains of intergroup‐related attitude, including measures of racism, sexism, homosexual prejudice, and ethnic and religious ingroup identification. In each of these five domains, meta‐analysis indicated that the statistical interaction of SDO and RWA accounted for an average of less than .001% variance in addition to their linear combination. It is concluded that the association between SDO and various discriminatory attitudes and beliefs is only extremely weakly dependent on RWA, and vice‐versa, suggesting that these two ideological attitudes are primarily additive, rather than interactive, in nature.
