In response to "The Bell Curve," notes that the effects of IQ on crime and delinquency are mediated by gender and age in a fashion that is not readily explained by a reduction to genetic differences. Discusses possible interrelationships among IQ, delinquency, and school performance, and suggests that the causal link between IQ and…

Like the "scientific" approaches of craniometry and eugenics, Herrnstein and Murray's methods and arguments reveal an ideological position not only on African Americans but also on the role of women. Points out their focus on women in discussions of "illegitimacy," birth control, and parenting, and their targeting of poor…

"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…

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'…

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;…

Argues that Herrnstein and Murray's cognitive stratification is not intrinsically ominous, since context determines its meaning; their "intelligence" data actually measures educational achievement; environmental effects are underestimated; and analyses and social policy recommendations are bound to the U.S. context. Concludes that…
