The entire thesis of "The Bell Curve" disintegrates due to biased use of data, misrepresentations, and logical inconsistencies. Five basic flaws are: inferring causality from correlation, use of dubious racial categories, contradictory arguments concerning the immutability of cognitive ability and the relative contributions of heredity…

Reports a study using meta-analytical procedures to compare WISC-R subtest performance patterns of 29 samples of retarded, average, and above average intelligence children. Shows how the study results in distinct WISC-R profiles for each group and demonstrates how the subtest performance patterns are strongly related to overall intellectual level.…

Discusses results of a study comparing the self-concept of intellectually gifted 9th-grade- students with that of intellectually average students, and investigates the relationships that existed among self-concept, intelligence test performance, reading comprehension, mathematics achievement, and overall composite achievement. No significant…

"The Bell Curve" declares that studies of separated identical twins--the "purest" of "direct" methods for estimating IQ heritability--indicate a value of +.75-+.80. But, the main study cited suggests a heritability of "two-thirds" for the middle class, and Herrnstein and Murray neglect to mention numerous…

Criticizes claims in "The Bell Curve" that a high value for heritability of intelligence constrains the extent to which environmental changes can increase intelligence. Cites adoption studies and the increasing intelligence of successive cohorts of U.S. children as evidence that intelligence can increase substantially without heroic…

Criticizes Herrnstein and Murray for their lack of respect for the truth, displayed throughout "The Bell Curve"; their willingness to encourage disharmony between groups they identify as cognitively different and to foment fear and distrust of an alleged underclass portrayed as dangerous and beyond help; and their lack of interest in…

Early readers came from higher socio-economic levels and smaller families, their mothers had more education, they spent more time in sedentary activities, and they received a variety of kinds of help. (Authors)

Commentary on "The Bell Curve." Points out that Herrnstein and Murray do not acknowledge their politically conservative funding sources. Discusses bias and inadequacies of IQ tests, lack of evidence of intergenerational reproduction of occupational classes, current underemployment of highly educated people, and the authors'…

"The Bell Curve" claims that most human differences and almost all social injustices can be traced to intelligence, and that distribution of intelligence should influence distribution of educational resources to allow students to find their proper and inevitable place in society. Applied to educational policy, this vision of the world…

Reviews controversies over intelligence and intelligence testing, focusing on impacts on Canadian society in the past century. Discusses eugenics movements and related immigration policies. Suggests that both "tails" of "The Bell Curve" (cognitive elite and underclass) are influenced by inaccurate methods, and that the middle…

Calls for careful but unemotional criticism of "The Bell Curve." Notes that: three chapters that deal with the IQ-race relationship have received most critical attention; genetically based racial categories do not exist; disadvantaged minority-group students have achieved success in Catholic schools with high expectations of students;…

Reports that no significant difference in reliability appeared between a heterogeneous and a homogeneous form of the same general science matching-item test administered to 316 sixth-grade students but that scores on the heterogeneous form of the test were higher, independent of the examinee's sex or intelligence. (SB)

Responds to "The Bell Curve" by arguing that IQ is merely a statistical fiction, an artificial construct not corresponding to any real entity. Discusses the "seductive statistical trap of factor analysis" as it relates to IQ tests, multiple intelligences, content and bias of IQ tests, lack of validity of IQ tests for individual…

Claims in "The Bell Curve" that Head Start and other early intervention programs are a failure and a waste of funds depend on a notion of cognitive ability reduced to IQ. They ignore other studies that demonstrate the success of such programs and that, consistent with Piagetian views, recognize the interrelationships of cognitive,…

Neutral summary of "The Bell Curve" (Herrnstein and Murray) by a former student of Herrnstein. Focuses on the emergence of a cognitive elite in the United States; relationships between IQ and poverty, educational attainment, unemployment, divorce, illegitimacy, welfare dependency, parenting competence, criminal behaviors, and voting;…
