William G. Sumner, who coined the term ethnocentrism, is famously known as America's first sociology professor. He taught social sciences at the Yale University. It is wondrous, really, how this world is made up of so many different people belonging to different races or ethnicities.
The Problem of Ethnocentrism. Ethnocentrism is believing in the superiority of oneâs ethnic group. Even though it sounds like ethnocentrism is bad, ethnocentrism has positive and negative qualities. For a minority group in oppressive conditions, ethnocentrism enables the group to create and sustain an identity over extended periods of time. The downside of ethnocentrism is that it causes a people from an ethnic group to look down on those who are from other ethnic groups. We American evangelicals can unfortunately be ethnocentric. We tend to express our ethnocentrism when we travel abroad.
