 This insight led Boas to reject the "stage"-based organization of ethnological museums, instead preferring to order items on display based on the affinity and proximity of the cultural groups in question.Boas also introduced the ideology of cultural relativism, which holds that cultures cannot be objectively ranked as higher or lower, or better or more correct, but that all humans see the world through the lens of their own culture, and judge it according to their own culturally acquired norms.For Boas, the object of anthropology was to understand the way in which culture conditioned people to understand and interact with the world in different ways and to do this it was necessary to gain an understanding of the language and cultural practices of the people studied.
