The correct answer is cultural relativism
Cultural relativism is a perspective of anthropology that sees different cultures free of ethnocentrism, which is to say without judging the other from their own vision and experience.
The perspective of cultural relativism is a construction of Anthropology, idealized by names like Franz Boas, and also used in Sociology.
As a scientific concept, cultural relativism presupposes that the researcher has a neutral view of the set of habits, beliefs and behaviors that at first seem strange to him, resulting in cultural shock.
