What is the belief that one's own culture is superior to others called?

The belief that one's own culture is superior to others is referred to as ethnocentrism. This concept arises from the tendency of people to view their own cultural norms and values as the standard by which other cultures are judged. Ethnocentrism can lead to misinterpretations and misunderstandings of different cultures, as individuals may perceive practices that differ from their own with bias or disdain.

Recognizing ethnocentrism is important, especially in public speaking and intercultural communication, where appreciation of diverse perspectives can enrich a dialogue and foster mutual respect. Understanding this term helps speakers to be mindful of their own biases and encourages an openness to learning from different cultures.
