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.
Ethnocentrism is the view that one particular ethnic group is somehow superior to all others. The word ethnocentrism derives from the Greek word ethnos, meaning nation or people, and the English word center. A common idiom for ethnocentrism is tunnel vision.
