Ethnocentrism in social science and anthropology—as well as in colloquial English discourse—means to apply one's own culture or ethnicity as a frame of reference to judge other cultures, practices, behaviors, beliefs, and people, instead of using the standards of the particular culture involved. Since this judgment is often negative, some people also use the term to refer to the belief that one's culture is superior to, or more correct or normal than, all others—especially regarding the distinctions that define each ethnicity's cultural identity, such as language, behavior, customs, and religion. In common usage, it can also simply mean any culturally biased judgment. For example, ethnocentrism can be seen in the common portrayals of the Global South and the Global North.

Racism is discrimination and prejudice against people based on their race or ethnicity. Racism can be present in social actions, practices, or political systems that support the expression of prejudice or aversion in discriminatory practices. The ideology underlying racist practices often assumes that humans can be subdivided into distinct groups that are different in their social behavior and innate capacities and that can be ranked as inferior or superior. Racist ideology can become manifest in many aspects of social life. Associated social actions may include nativism, xenophobia, otherness, segregation, hierarchical ranking, supremacism, and related social phenomena. Racism refers to violation of racial equality based on equal opportunities or based on equality of outcomes for different races or ethnicities, also called substantive equality.
