That there is a significant degree of observable average difference in the intelligence quotients of blacks and whites is an established fact. The explanations for this offered by Herrnstein and Murray ("The Bell Curve," 1994) ignore the equally well-established facts of discrimination and disadvantage over centuries. (SLD)

Associations between community environment and cognitive ability were studied in 167 adoptive and 175 nonadoptive Colorado families. Seven families were omitted. A proposed model, tested by census measures, finds several aspects of communities showing environmental relationships with child IQ over parental influences. Rural communities have a…

The relevance of intelligence testing for schools within one district, the Sacramento (California) school district and the state of California is explored, and applications of intelligence theory in district schools and classrooms are discussed. Intelligence, for purposes of this discussion, is the aggregate capacity of each student's…

The strongest recent statement that inequality in America is the natural result of a free market came in "The Bell Curve: Intelligence and Class Structure in American Life" by Richard Herrnstein and Charles Murray. These authors argued that intelligence determines how well people do in life, and the rich are rich largely because they are…

"The Bell Curve" by Richard Herrnstein and Charles E. Murray has created a great deal of controversy because of its assertion that the key to explaining inequality and social problems in the United States is stratification by a unitary entity called intelligence, or cognitive ability, as measured by the intelligence quotient (IQ). Their…

Several common assumptions about human intelligence are challenged in this paper. The "bucket" theory of intelligence describes intelligence as a stable psychological characteristic which affects learning, and which, when accurately measured, predicts an individual's learning capacity. The authors reject the idea that people who have…

Pseudoscience, or the process of persuasion by establishing a pretense of scientific discovery, is examined in this book in an effort to dispel false notions about the validity of various measures of intelligence and the correlations of genetics to mental ability. The history and development of concepts related to hereditary intelligence and…

West Indian children in British schools tend to have lower scores than white children on conventional tests of achievement. However, when factors such as social class, length of exposure to the British educational system, and school quality are taken into account, the differences in test scores between blacks and whites narrow. A broader concept…

In his book, "I.Q. in the Meritocracy," Richard J. Herrnstein (1973) calls on a classic article by Barbara S. Burks (1928) to support his position that a large part of the variation in intelligence can be accounted for by variation in heredity, as distinguished from variation in environment, and from covariation of heredity and…

A review of the twin literature and analyses of two large twin samples found identical twin correlations higher than fraternal twin correlations by about .20 for a variety of traits of ability, personality and interests. This was interpreted as indicating that about half of the variation among people in a broad spectrum of psychological traits is…

Discusses issues raised in "The Bell Curve: Intelligence and Class Structure in American Life" (Richard Herrnstein, Charles Murray), a controversial book that looks at the role of intelligence in shaping social structure. The authors' methodology, approach, and interpretations of statistical data are criticized. It is suggested that a…

Drawing upon the burgeoning research in neurology, as well as stories of real children, this book charts the brain's development, from conception through the critical first 5 years of life. In examining the many factors that play crucial roles in that process, the book explores the evolution of the senses, motor skills, social and emotional…

Suggests that Dunn's genetic explanation for low Hispanic academic achievement is flawed, racist, and scientifically unfounded. Reviews historical efforts to suppress foreign language use and instruction in the United States. Calls for a reexamination of the implications of IQ test results in light of socioeconomic and cultural differences.…

Reviews criticism of Dunn's monograph on Hispanic-Anglo differences in IQ scores. Discusses the heritability and malleability of IQ, the reciprocal relationship between achievement and intelligence, negative effects of schooling for some caste-like minorities, and superior cognitive skills among balanced bilingual students. Contains 19 references.…

The egalitarian dogma, the belief that blacks and whites are genetically equal in cognitive ability, has been perpetuated through intimidation and pious thinking. Data on racial differences and the corruption of scholarship that causes them to be ignored are discussed. (SLD)
