Ethnocentrism must be understood so that it can be avoided, because it is the belief in the superiority of one’s own ethnic group, which could ultimately make it very difficult to truly study and learn about a culture if you are constantly allowing yourself to believe that you are better than them; of course by “better” it is not necessarily referring to a bold arrogance or pride, but more so a hidden arrogance or pride that a lot of the time we don’t realize we even have.
