Final answer:
The term for viewing one's own ethnic group as central and judging others by this standard is ethnocentrism. This belief can lead to misunderstandings and conflicts between different cultures.
Step-by-step explanation:
Viewing one's own ethnic group as central and "correct" while judging the rest of the world according to this standard is known as ethnocentrism. Ethnocentrism is the idea that one's own culture is inherently better than other cultures and often involves evaluating and judging another culture based on how it compares to one's own cultural norms. For example, an American may perceive driving on the left side of the road in England as wrong rather than simply different. Ethnocentrism can also manifest in more severe forms, including disdain or dislike for other cultures, which can lead to misunderstanding, stereotyping, and conflict. An excessive level of ethnocentrism has historically led to instances of cultural imperialism and subjugation.
