Through Caste, Social stratification and Discrimination

The theory was initially proposed in 1992 by social psychology researchers Jim Sidanius, Erik Devereux, and Felicia Pratto. It observes that human social groups consist of distinctly different group-based social hierarchies in societies that are capable of producing economic surpluses. These hierarchies have a trimorphic (three-form) structure, a description which was simplified from the four-part biosocial structure identified by van den Berghe (1978). The hierarchies are based on: age (i.e., adults have more power and higher status than children), gender (i.e., men have more power and higher status than women), and arbitrary-set, which are group-based hierarchies that are culturally defined and do not necessarily exist in all societies. Such arbitrariness can select on ethnicity (e.g., in the US, Bosnia, Asia, Rwanda), class, caste, religion (Sunni versus Shia Islam), nationality, or any other socially constructed category. Social hierarchy is not only seen as a universal human feature – SDT argues there is substantial evidence it is shared, including the theorized trimorphic structure – among apes and other primates.

Personal level

According to researchers, individuals who score high on the psychological tendency known as social dominance orientation are more likely to support discriminatory policies and the hierarchical organization of the social world. Individuals with high levels of social dominance orientation are also more inclined to endorse ideologies such as racism, sexism, homophobia, nationalism, and militarism. Theorists argue that social dominance orientation is a psychological tendency that has developed through evolutionary processes and is present, to varying degrees, in all individuals.
