Final answer:
Cultural relativism is the anthropological principle that recognizes all human populations as having equal capacities for culture, countering discriminatory views of intellectual and cultural inferiority.
Step-by-step explanation:
Anthropologists recognize that all human populations have equivalent capacities for culture, which counteracts the discriminatory belief that some populations are intellectually and culturally inferior. This concept of equivalence among human cultures is known as cultural relativism, implying that no culture is superior to another and each must be understood in its own context. Cultural relativism encourages the appreciation of different cultures based on their unique qualities and accomplishments, rather than judging them against a biased and ethnocentric standard.
