Bias in Mental Testing

Evidence for an Alternative to the Heredity-Environment Controversy
  • Ernest M. Bernal
Part of the Perspectives on Individual Differences book series (PIDF)


Jensen, in his Bias in Mental Testing (1980) and other publications, has carefully documented a corpus of research on general intelligence (g) spanning some 75 years. His work, however, is perhaps best known for its exploration of minority-majority group differences in mental abilities (Jensen, 1969a,b,c), which, through the applications of genetic theory and heritability indices to a plethora of test data, he has interpreted to be for the most part genetically determined (Jensen, 1970). This basic finding, furthermore, cannot, according to Jensen (1980), be rationalized away by any extant studies of cultural or racial bias in professionally acceptable (i.e., well constructed) achievement, academic aptitude, or intelligence tests.
