The author suggests that more empirical evidence will have to be found before environmental influence can be declared insufficient to the cause of Negro-White I.Q. score differences. (Editor/RT)

Findings from a study reported in this paper indicate that the differences in family background that affect IQ are largely the result of genetic differences among parents, which affect the parents' own status attainment and which are passed on genetically to their offspring, whose status attainments are subsequently affected.

Analyzes and refutes two propositions of H.J. Eysenck: (a) that intellectual differences in our culture are overwhelmingly determined by genetic factors, and (b) that the 15-point mean I.Q. gap between black and white Americans is largely determined by genetic factors. (JM)

The thesis that intelligence is based on heredity was dramatically revived in 1969 by an article in the "Harvard Educational Review" by Arthur Jensen, a psychologist at the University of California at Berkeley. The article, which received wide attention, was sharply criticized by those who hold that it is environment rather than genes which puts…

In this address, Jensen discusses his views on the effects of heredity and environment on human intelligence, in an attempt to clarify his original statements on this subject. Since his article appeared in the "Harvard Educational Review" in 1969, the term "Jensenism" has accrued a variety of meanings through popular usage (according to Jensen)…

In an effort to isolate the emergence and causes of social class differences in intellectual performance, this longitudinal study was undertaken as a follow-up on a cross-sectional study that yielded no social class differences on the Cattell Infant Intelligence Scale for 12-, 18-, and 24-month-old black children. In the present study, 89 children…

This collection of essays about intelligence stems from the revived nature-nurture controversy about the origins of mental abilities, led notably by Arthur Jensen, whose article in 1969 created a furore in the U.S.A., and more lately by H. J. Eysenck in Britain. In planning this book, an attempt has been made to step back from the debate itself…

This paper, focusing on differences between Caucasians and Negroes in the United States, summarizes from a "scientific standpoint" the main facts and theoretical issues involved in the study of human racial differences and behaviors. Three principles are considered to govern the orientation of this document: (1) objective research and…

It has been said that the heritability of learning ability or of intelligence is irrelevant to teachability. In support of this statement we see it pointed out that a child or a group of children show some response to training, and this is held up as evidence against the heritability of intelligence or learning ability. Most estimates of the…
