Recently, the GSS released the survey results for the year 2012. And a skin color variable has been included. But rather than using the SDA program, available here, I used the GSS cumulative datafile 1972-2012 for SPSS, available here. This … Continue reading
Introduction. If color-based discrimination becomes more intense at a later age, when darker-skinned individuals face discrimination in the labor market and thus depressing their economic opportunities at every level, for instance, the colorism hypothesis could have argued that IQ measured … Continue reading
Previously, we established that skin color and intelligence are correlated in the NLSY97 sample as predicted by hereditarian theory. Continuing this investigation, we looked into how these variables go together within and between African American families in the same sample. In … Continue reading
The meaning of a Jensen Effect on the Color Effect Dalliard showed that IQ correlates with color in both the American Black and Hispanic populations (a color effect) and, importantly, that the IQ-color correlations are positively related to a subtest’s … Continue reading
(10/18/2014 update: data from two additional studies — Martínez et al. (2007) and Ruiz-Linares et al. (2014) — have been added.) Over the last decade, scores of large scale admixture-mapping studies have been conducted largely in an attempt to elucidate the … Continue reading
In an earlier article, I have shown that the magnitude of sibling correlations among NLSY-ASVAB subtests correlates with the magnitude of g-loadings, but moderately with the magnitude of black-white IQ gaps in those subtests using Jensen’s method of correlated vectors, … Continue reading
Some things never change Nearly 100 years ago George Ferguson tested the racial genetic hypothesis of IQ differences and found the following remarkable results, as reported by Baker (1974): Just a couple of days ago, the awesome Audacious Epigone pointed … Continue reading
Charles Murray’s 2005 Commentary article, The Inequality Taboo, expressed the idea that the post genomic era has finally brought us a method to resolve the question of genes, race, and intelligence: To the extent that genes play a role, IQ … Continue reading
Introduction We have shown, amongst other things, that pre-market measures of IQ substantially statistically explain the association between color and outcomes in the US. This implies that the adult color-outcome differences are substantially caused by IQ differences, rather than vice … Continue reading
It has come to my attention that interest in IQ-HBD is on the wane even amongst HBDers and HBDresses. Given this state of affairs, I have decided to compose this post as pithily as possible in hopes that my main … Continue reading
