Dissects the controversial Jensen paper, and concludes that Jensen is wrong. (DM)

Geneticists discuss the Jensen paper and suggest upon reviewing the evidence, that the question of genetic differences between the IQ of blacks and whites cannot be answered in the present circumstances. (DM)

Attempts to show that the purportedly scientific'' empirical basis of credentialism and I.Q.-ism'' is false; and to facilitate linkages between the groups who are being discriminated against the workers' movements within the white male labor force, by showing that the same mechanisms are used to divide strata against one another so as to…

Data are presented from families of monozygotic twin pairs which give evidence of genetic variance on the Block Design Test, a nonverbal measure of intelligence. Analyses of genetic and environmental effects on behavior are possible with this kind of information. (SA)

Research has shown that differences among ordinary people in intelligence and personality depend equally on individual genetic variability and on differences in the environments that siblings experience within the same family, not differences in the neighborhood, school, and community environments. As of yet, there are no adequate theories to…

Comparing group intelligence according to racial or geographic orgin has neither social nor scientific value; the emphasis in education and the social economy is not the creation of equality but the development of each individual to his maximum performance. (Author/JM)

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. (Author/EB)

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)

Ronald C. Johnson argued that if early environmental stimulation or deprivation has a significant effect on intellectual ability, then individuals who are genetically identical and who are exposed to a common early environment should resemble one another more closely in IQ than similar individuals who have not shared a common environment. Johnson…
