Crude and dangerous ideas about the genetic heritability of intelligence, and a supposed biological basis for the Black/White achievement gap, are alive and well inside the education policy process but taking new and more subtle forms. Drawing on Critical Race Theory, the paper analyses recent hereditarian writing, in the UK and the USA, and…

The issue of race differences in intelligence, especially with respect to American black and white populations, is adjudged to be "nonsensical" in terms of the framing of the question, the populations sampled, the testing instruments utilized, and the concept of "intelligence" postulated. (Author/EH)

Reviews the furor and reaction to Arthur Jensen's controversial genetic theory of intellectual differences. The cases of Shockley, Eysenck, and Herrnstein are also discussed as instances in which intellectual debate was supplanted by academic persecution and impassioned rhetoric. (EH)

Summarizes the positions of leading proponents of the belief in the biological basis of differences in intelligence, reviewing the ideas of Arthur Jensen, J. Phillipe Rushton, and the currently controversial "The Bell Curve" by Charles Murray and Richard Herrnstein. Relations between social perceptions of race and class are discussed.…

Finds that the available data for the heretability of intelligence is inadequate to settle the question conclusively. Argues that the benefits of diversity can only be realized if equality of opportunity is complimented by equality of status. (EH)

Milkman (TM 504 643) accuses Arthur Jensen of misapplying heritability data in speculating on the causes of racial differences in intelligence test scores, and offers a method for illuminating Jensen's alleged error. It is contended in this article that Milkman has misconstrued Jensen's argument and that his method is without point. (Author/CTM)

Reviews Richard Herrnstein's article and book concerning I.Q. and argues that the questions of the nature of intelligence and the respective influences of environment and heredity are important not just in the interpretation of statistical evidence but because these questions have implications in the lives of human beings. (Author/JM)

The author reexamines the controversy surrounding his genetic hypothesis in an attempt to clarify his contention that differences in IQ scores between blacks and whites may be attributable as much to heredity as environment. (EH)

This paper discusses the nature-nurture controversy concerning the origins of mental abilities. Specifically, the author looks at the viewpoint of Arthur Jensen and critically examines his work. This paper presents an overview of Jensen's position followed by a discussion of shortcomings in his methodology and research techniques. The author…

Sets of randomly generated numbers are used to produce simulated data sets to illustrate that high heritability of a property within each of two populations may be consistent with a vanishingly small heritability in the combined population. (A response by Jensen appears in the next issue of Journal of Educational Statistics, p.385). (CTM)

Michael Levin argues that data from the study are consistent with a black/white IQ difference that is significantly genetic. Richard Lynn maintains that adoption by middle-class, white families has no effect on intelligence. Waldman, Weinberg, and Scarr respond to these criticisms and support the original conclusions. (SLD)

Evidence on the poorer spatial visualization ability in various Negro populations compared to the White populations and on the direction and magnitude of sex differences in spatial ability relative to other abilities suggests the genetic hypothesis that spatial ability is enhanced by a sex-linked recessive gene and that, since the 20-30 percent…

The publication of "The Bell Curve" by R. Herrnstein and C. Murray enraged many with its contention that black children are genetically less able to learn because of their race and its suggestions that some groups may be less worthy of the expenditure of attention and resources because of a reduced capacity for education. This collection…

An analysis of intelligence quotient (IQ) in relation to head size was performed on about 14,000 children aged 4 and 7 years, almost equally divided by race (white and black) and sex. Correlation between head size (by inference, brain size), and IQ is established as a within-families correlation. (SLD)

Summarizes a series of studies from the Hawaii Family Study of Cognition on possible genetic and social environmental determinants of individual differences in and racial/ethnic differences between groups on intelligence and attainment. These studies, which focused on Japanese and Caucasian Americans, illustrate the complex, interactive, and…
