The cultural distance approach is descrjbe'd as an Amalgam of the environmental and social psychology points of view. It holds that any subcultUre operating according to principles not present or equally operatiye in the majority culture processes functional information differently from the majority culture. Therefore, minority performance on tests-based uponand validated by themajority culture will show response patterns different from the norm. These patterns are indicators of what is present in the tests that is salient to each subculture and to the majority culture. The tests, however, are not responsive to what is salient to the specific minority subbultures but absent in the.majority culture. Thus, bias is assumed to be present in all standardized IQ tests. Evidence from the United States and around the world shows that multicultural societies must, and.for'the most part do, interpret standardized IQ scores of minority individuals in a different light from those of majority individuals.
