when a person believes that his culture is superior to other culture it is called
Ethnocentrism William G. Sumner defined ethnocentrism as "the technical name for the view of things in which one's own group is the center of everything, and all others are scaled and rated with reference to it." He further characterized ethnocentrism as often leading to pride, vanity, belief in one's own group's superiority, and contempt for outsiders.[4] These problems may occur from the dividing of societies into in-groups and out-groups.[5] Ethnocentrism is explained in the social sciences and genetics. In anthropology, cultural relativism is used as an antithesis and antonym to ethnocentrism.[6]
