Of all the political theories used to understand our complex political system, one of the most useful is “Social Dominance Theory” (SDT) developed by Sidanius and Pratto. This is a sociological theory that seek to make sense of social hierarchies and how they are formed and maintained. To understand social hierarchies is to understand discrimination, oppression, stereotypes, inequality, racism, sexism, ageism, homophobia, nationalism, and the like. In short, SDT provides a framework for understanding power and group inequality.
