The text Ethnology and Intercultural Communication in Indonesia explores the concept of ethnocentrism and its significant impact on intercultural communication. Ethnocentrism is defined as the universal tendency of individuals to prioritize their own culture, leading to a subjective evaluation of other cultures. This perspective often results in negative judgments, as the belief that "our way is the right way" can foster feelings of superiority. Keesing emphasizes that folklore and cultural narratives often reinforce this ethnocentric view, legitimizing one’s customs and practices while marginalizing others. The implications of ethnocentrism in Indonesia highlight the importance of understanding cultural differences to improve communication and foster mutual respect in a diverse society.
