14 Reasons IQ Race Gap is Genetic
INTELLIGENCE DIFFERENCES are genetic.
Reasons we know that the intelligence gap between Whites and Blacks is genetically based:
1. There are pervasive physical differences between Whites and Blacks, including brain size and structure, bone density, muscularity, fat storage, hormones, and metabolic rate. Whites’ brains average 6-8% larger; larger brains being correlated with higher intelligence. There are also differences in behavioral traits such as sexual activeness, marital fidelity, birth rate, gestation period, and maturation rate. These indicate a biological strategy of greater parental investment for Whites, also correlated with higher intelligence.
2. Genetic divergence of the races has accelerated since Whites/Blacks split over 60,000 years ago, and a majority of genes affect the brain. Whites evolved in Northern regions with greater cognitive demands to plan and prepare for harsh Winters.
3. Many specific gene alleles have been linked to higher intelligence, and in every case these alleles occur with greater frequency in Whites than Blacks.
4. White-Black academic and cultural disparities, including an IQ gap of 1SD or more, are consistent across geographic regions and technological eras. They persist throughout various cultures, and in spite of massive uplift programs benefiting Blacks and some devastating wars afflicting Whites.
5. When African Blacks took control of White-governed nations with advanced infrastructure, some of them rich in resources, the level of civilization collapsed.
6. Twin/adoption studies consistently show that core traits including intelligence are mostly genetic-based for both Whites and Blacks, and rule out cultural factors as possible causes of the IQ gap. Identical twins reared in random families have much closer IQs than fraternal twins reared in the same family. Genome-wide gene association studies reach the same conclusion.
7. The 1SD White/Black IQ gap is evident in the first tests of children at age 3, when cultural differences are minimal, and is consistent throughout the lifespan.
8. Intensive and extravagant education programs have mostly failed to raise Black IQ or academic achievement, having but minimal effect.
9. Blacks adopted as infants into middle-class White families have, by adulthood, the same 1SD lower IQ than their adopted White cohorts. Mixed race cohorts have intermediate IQs.
10. Black children of high-IQ parents have IQs midway between their parents’ and the lower black mean, in accordance with the hereditarian principle of regression toward the mean. White children regress toward the 1SD higher White mean, and so they have higher IQs than Blacks with parents of the same IQ. Children of lowest-income Whites score higher on SATs than children of highest-income Blacks.
11. Mixed-race Blacks having more White ancestry have higher IQs than those with less White ancestry. Reported ancestry is an even stronger predictor of their IQs than skin lightness.
12. The White/Black gap is largest on IQ subtests that are the most g-loaded and heritable. These items have the closest correlation with biological measures such as brain size, cortical thickness, rate of glucose metabolism, nerve conduction velocity, and reaction time.
13. Blacks do no better on intelligence tests that are non-cultural, such as Raven’s Progressive Matrices, Backward digit span, and Reaction time tests.
14. Blacks in White nations not only enjoy the benefits of White civilization, but are advantaged in many respects: pervasive anti-White discrimination in education and hiring, high taxes/insurance premiums paid by Whites for Black welfare/benefits, special education programs, and an entertainment media that extols Blacks and ridicules Whites. Blacks have much higher self-esteem than Whites.
