Abstract

JENSEN has argued that the undoubted differences in mean IQ scores between racial groups in the United States reflect differences in genetic endowment. But a major problem in the interpretation of these differences is the difficulty of studying environmental and genetic effects separately. Each race tends to have, for historical reasons, characteristic child-rearing practices which are to some extent independent of social class. Hence the argument that because black children tend to have lower IQs than white children of the same social class they are genetically inferior is unconvincing; the inferior test scores could result from differences in the microenvironment of the family, such as linguistic practices and attitudes to achievement.
