The culture-only (0% genetic–100% environmental) and the hereditarian (50% genetic–50% environmental) models of the causes of mean Black–White differences in cognitive ability are compared and contrasted across 10 categories of evidence: the worldwide distribution of test scores, g factor of mental ability, heritability, brain size and cognitive ability, transracial adoption, racial admixture, regression, related life-history traits, human origins research, and hypothesized environmental… Expand
Cognitive ability testing and adverse impact in selection: Meta-analytic evidence of reductions in Black-White differences in ability test scores over time
Black-White differences in cognitive ability test (CAT) performance were examined metaanalytically in this study. The primary purpose was to test a cultural/developmental theory of differences in CATExpand
The Totality of Available Evidence Shows the Race IQ Gap Still Remains
TLDR
Evidence is reviewed that the distribution of IQ scores around the world shows averages of 106 for East Asians, 100 for Whites, 85 for U.S. Blacks, and 70 for sub-Saharan Africans; and race differences are most pronounced on the more g-loaded subtests whose scores show the most heritability. Expand
Race differences in IQ: Hans Eysenck’s contribution to the debate in the light of subsequent research
Abstract Hans Eysenck was one of the earliest protagonists in the controversy over race and intelligence. He believed that the observed variability in IQ scores is genetically determined to a highExpand
Racial and ethnic group differences in the heritability of intelligence: A systematic review and meta-analysis
Abstract Via meta-analysis, we examined whether the heritability of intelligence varies across racial or ethnic groups. Specifically, we tested a hypothesis predicting an interaction whereby thoseExpand
The cultural malleability of intelligence and its impact on the racial/ethnic hierarchy
This commentary highlights previous literature focusing on cultural and environmental explanations for the racial/ethnic group hierarchy of intelligence. Assumptions underlying definitions ofExpand
Testing for Racial Differences in the Mental Ability of Young Children
On tests of intelligence, Blacks systematically score worse than Whites, whereas Asians frequently outperform Whites. Some have argued that genetic differences across races account for the gap. UsingExpand
Genetic and Environmental Determinants of IQ in Black, White and Hispanic Americans: A Meta-analysis and New Analysis
The authors conducted a meta-analysis of interactions between behavioral genetic variance components (ACE) and race/ethnicity for cognitive ability. The differences between the variance componentsExpand
Race and IQ: A Theory-Based Review of the Research in Richard Nisbett's Intelligence and How to Get It
We provide a detailed review of data from psychology, genetics, and neuroscience in a point-counterpoint for- mat to enable readers to identify the merits and demerits of each side of the debate overExpand
Biogeographic Ancestry, Cognitive Ability and Socioeconomic Outcomes
The cause(s) of ubiquitous cognitive differences between American self-identified racial/ethnic groups (SIREs) is uncertain. Evolutionary-genetic models posit that ancestral genetic selectionExpand

Previous work has shown that black-white racial group differences in intelligence are largest on the most g-loaded subtests. Because these are the ones most genetically influenced, it is implied thatExpand
Absence of a relationship between degree of white ancestry and intellectual skills within a black population
TLDR
If genetic, racial differences do contribute to average intellectual differences between blacks and whites, then those blacks with higher degrees of white ancestry should perform better on intellectual tests than those with lesser degrees of admixture. Expand
IQ and Race
TLDR
The argument that because black children tend to have lower IQs than white children of the same social class they are genetically inferior is unconvincing; the inferior test scores could result from differences in the microenvironment of the family, such as linguistic practices and attitudes to achievement.
