Ethnocentrism is the tendency to look at the world primarily from the perspective of one's own culture. It is defined as the viewpoint that “one’s own group is the center of everything,” against which all other groups are judged. Ethnocentrism often entails the belief that one's own race or ethnic group is the most important and/or that some or all aspects of its culture are superior to those of other groups. Within this ideology, individuals will judge other groups in relation to their own particular ethnic group or culture, especially with concern to language, behaviour, customs, and religion. These ethnic distinctions and sub-divisions serve to define each ethnicity's unique cultural identity.

Anthropologists such as Franz Boas and Bronislaw Malinowski argued that any human science had to transcend the ethnocentrism of the scientist. Both urged anthropologists to conduct ethnographic fieldwork in order to overcome their ethnocentrism. Boas developed the principle of cultural relativism and Malinowski developed the theory of functionalism as tools for developing non-ethnocentric studies of different societies.
