Social dominance orientation

Social dominance orientation (SDO) is a personality trait which predicts social and political attitudes, and is a widely used social psychological scale. SDO is conceptualised as a measure of individual differences in levels of group-based discrimination; that is, it is a measure of an individual's preference for hierarchy within any social system and the domination over lower-status groups. It is a predisposition toward anti-egalitarianism within and between groups. The concept of SDO as a measurable individual difference is a product of social dominance theory.
