Right-Wing Authoritarianism and Social Dominance Orientation Differentially Moderate Intergroup Effects on Prejudice

Research has shown that two individual difference dimensions, Right-Wing authoritarianism (RWA) and Social Dominance Orientation (SDO), consistently predict prejudice. Traditionally it has been assumed that RWA and SDO both index generalized dispositions to dislike outgroups and those who differ and therefore predict prejudice similarly. An alternative approach suggests that RWA and SDO express different motivational bases for prejudice that differentially interact with intergroup conditions to predict prejudice. This was tested by investigating students' reactions to varying descriptions of a bogus immigrant group. As hypothesized, the degree to which RWA and SDO predicted opposition to the immigrants was differentially contingent on the degree to which the immigrants were described as economically competitive, socially threatening (deviant) and socio-economically disadvantaged.
