Ethnocentrism: This is the belief in the inherent superiority of one's own ethnic group or culture. It's like preferring your home team over others because you believe they're inherently better.
Cultural Relativism: This is the principle that an individual human's beliefs and activities should be understood by others in terms of that individual's own culture. It’s like trying to understand why someone prefers Android over iOS by considering their personal experiences and preferences.
Cultural Diffusion: This refers to the spread of cultural items—such as ideas, styles, religions, technologies—between individuals. Imagine it as sharing a popular song on social media; soon enough people from different circles start listening to it too.
