How heritability misleads about race.
نویسنده
چکیده
The Bell Curve revives and elaborates an argument given by Jensen to the effect that facts about heritability of IQ in whites dictate that blacks are genetically inferior in IQ. But clarification of the concept of heritability shows that this reasoning is fallacious. Heritability is an uninteresting measure that only misleads us about race.

We provide a detailed review of data from psychology, genetics, and neuroscience in a point-counterpoint format to enable readers to identify the merits and demerits of each side of the debate over whether the culture-only (0% genetic-100% environmental) or nature + nurture model (50% genetic-50% environmental) best explains mean ethnic group differences in intelligence test scores: Jewish (mea...

This experiment was conducted to estimate genetic parameters of some of the important traits of silkworm in two populations, namely, Japanese and Chinese lines in Iranian Silkworm Rearing Co-Natanz. Based on single pair mating method, 9 male moths mated with 9 female moths and then raised under standard environmental conditions. Performance of 30 progenies of each pair was recorded. Heritabilit...

PURPOSE To determine the heritability of refractive error and the familial aggregation of myopia in an older population. METHODS Seven hundred fifty-nine siblings (mean age, 73.4 years) in 241 families were recruited from the Salisbury Eye Evaluation (SEE) Study in eastern Maryland. Refractive error was determined by noncycloplegic subjective refraction (if presenting distance visual acuity w...
متن کاملBody mass index modulates blood pressure heritability: the Family Blood Pressure Program.
BACKGROUND Candidate gene and twin studies suggest that interactions between body mass index (BMI) and genes contribute to the variability of blood pressure (BP). To determine whether there is evidence for gene-BMI interactions, we investigated the modulation of BP heritability by BMI using 4,153 blacks, 1,538 Asians, 4,013 whites, and 2,199 Hispanic Americans from the Family Blood Pressure Pro...
