Answer:
Systematic study of an ethnic group's religious core belief that one's own ethnic group or culture is superior to that of others.
Explanation:
In Social Sciences and Anthropology, Ethnocentricity is defined as a "systematic study of an ethnic group's religious core belief that one's own ethnic group or culture is superior to that of others".
It is an act of judging other's culture based on one's own. The belief is prejudiced as it disregards the merits of different culture and places itself above than the other.
Ethnocentricity determines language, food, behavior and religion as a medium to compare with other culture and then places its own culture above it.
