Dimensions of Social Dominance: Their Personality and Socio-political Correlates within a New Zealand Probability Sample.

Social Dominance Orientation (SDO) was introduced as a unidimensional construct predicting numerous socio-political attitudes. However, recent findings suggest that SDO is composed of two sub-dimensions: dominance (SDO-D) and anti-egalitarianism (SDO-E). Despite converging evidence concerning their empirical differentiability, there is little consensus on how to best define them. Thus, we examined the correlates of SDO-D and SDO-E using a broad array of personality, political, ethnic and gender issue variables within a New Zealand national probability sample (N = 5,741) with European and Māori participants. SDO-D primarily related to the personality trait of honesty-humility, hostile and benevolent sexism. SDO-E primarily related to political conservatism and pro-Māori policies. In many cases, the predictive power differed between SDO-D and SDO-E, and across ethnic groups. [ABSTRACT FROM AUTHOR]
