ABSTRACT
The claim that intelligence tests are culturally biased in favor of white middle-class children and are therefore invalid when applied to minority children (or to lower-class white children) is undoubtedly the commonest argument against studies of subpopulation differences. The SPSSI Council (1969) states:
We must also recognize the limitations of present-day intelligence tests. Largely developed and standardized on white middle-class children, these tests tend to be biased against black children to an unknown degree. While IQ tests do predict school achievement, we cannot demonstrate that they are accurate as measures of innate endowment. Any generalizations about the ability of black or white children are very much limited by the nature of existing IQ tests.
