RACE AND INTELLIGENCE

Intelligence

>"Despite popular assertions, a single factor for intelligence, called g [or "general intelligence"], can be measured with IQ tests and does predict success in life"
http://www.udel.edu/educ/gottfredson/reprints/1998generalintelligencefactor.pdf

>A public statement signed by 52 internationally known scholars, all professors or experts in intelligence and allied fields, claimed that "Intelligence is a very general mental capability that, among other things, involves the ability to reason, plan, solve problems, think abstractly, comprehend complex ideas, learn quickly and learn from experience … Intelligence, so defined, can be measured, and intelligence tests measure it well. They are among the most accurate (in technical terms, reliable and valid) of all psychological tests and assessments."

>The landmark book "The Bell Curve" compared intelligence, education, socioeconomic status, and a variety of other factors to see how positively they correlate with social success.

>None of the factors correlated as highly as IQ did (positively or negatively) in regards to job success, income, welfare dependency, illegitimacy, and crime.

>High national IQ corresponds strongly to a high average living standard at 0.73. If Blacks indeed have a lower IQ than Whites, one could easily make the argument that sharing living spaces lowers the quality of life for Whites yet raises it for Blacks.

>30 years of research on race differences in cognitive ability, based on multiple categories of evidence and dozens of research studies with thousands of research subjects, all converge and agree upon the indisputable fact that Whites and Blacks have different average levels of general intelligence. This remains true despite controls for poverty, health, education, and many other possible factors. The average White IQ is roughly 100 while the average Black IQ is roughly 85. This gap has been demonstrated repeatedly by every race and inteligence study ever conducted in every state, county, and school board and the same White-Black ratio has remained relatively constant since testing first started decades ago to the present.

>The evidence is so overwhelming that psychologists do not even attempt to argue that the massive gap does not exist, the only debate on the subject is what the exact cause is.

>The Minnesota Transracial Adoption Study tested the IQs of Whites, Blacks, and Mulattoes (half White and half Black) that were adopted into White upper-middle class homes. The study tested the adopted children's IQs at the age of 7 and there was a 10 year follow up when they were 17. The study is important because despite the fact that some of the Mulatto children considered themselves fully Black and that society considered them fully Black, they scored in between the White and Black children; 109 for adopted Whites, 99 for adopted mulattos, and 89 for adopted Blacks.

>This shows that despite having the same environment (adoption into upper-middle class White families) the higher the White ancestry of self- and socially-percieved Blacks, the higher the IQ. This study completely shatters the notion that "Racism" or "Black culture" is the cause of the IQ gap as these same social constructions would effect the Mulatto children (who considered themselves fully Black) as well as the Black children.

>There is a significant correlation between skin color and White ancestry in African-Americans (0.44)

>Modern science has found ways to remove cultural bias from intelligence testing. One example is by using Raven Matrices to measure intelligence.
http://onlinelibrary.wiley.com/doi/10.1111/j.2044-8341.1936.tb00690.x/abstract

>In a Raven Standard Progressive Matrices test, the subject is tested with patterns and geometric figures which are culture-independent and a computer calculates the score.
http://books.google.com/books/about/A_question_of_intelligence.html?id=5ggRAQAAIAAJ

>These tests correlate significantly (over .50) with IQ
http://www.udel.edu/educ/gottfredson/reprints/1996reviewRushton.pdf

>And as expected, despite having no cultural bias, they continue to show the large, measurable, and significant intelligence gap between Whites and Blacks.

>To date, despite claims that IQ tests are biased, not one single intelligence test has ever displayed equal scores for Blacks and Whites; one must either make the test so difficult that nobody can manage to get the questions correct or so easy that everyone obtains a perfect score to show testing equality, yet that would make the test meaningless and invalid.

>In fact, "public schools now spend more per capita on black children than on white." Also, "Contrary to environmentalist predictions, intervention beginning at age three makes no difference to the intellectual development of blacks [into adulthood]."

>The famous Milwaukee Project which spent $14 million in attempt to prove that the IQ gap could be removed with improved environment ended with the principal investigator "convicted and imprisoned for large-scale abuse of federal funding for private gain. Two of his colleagues were also convicted of violations of federal laws in connection with misuse of project funds… However, the project received uncritical acceptance in many college textbooks in psychology and education."

>As Albert Einstein famously wrote, "Insanity is doing the same thing over and over again and expecting different results." All of the excuses for Black underachievement have been refuted ad nauseam yet egalitarians refuse to budge, persisting that race doesn't exist and that this gap is the fault of White racism.

>Egalitarians often suggest that White racism lowers Black self-esteem and causes an inferiority complex. However, "Past research indicates that black adolescents consistently have higher self-esteem than white students. Other research demonstrates that self-esteem has positive effects on academic achievement. However, black students have lower academic achievement than white students while concurrently exhibiting higher self-esteem."

>Indeed, even the psychologist Claude Steele who coined the term "Stereotype threat" (anxiety or concern to conform to a negative stereotype) admitted that it does not explain the gap between Whites and Blacks through personal email. One study reports that "research is widely misinterpreted… as showing that eliminating stereotype threat eliminates the African American-White difference in test performance."

>Blacks mature faster than Whites
http://www.charlesdarwinresearch.org/Race_Evolution_Behavior.pdf

>The IQ gap reflects this; the gap is 0.7 standard deviation (1 SD is 15 points) at early childhood, 1 SD at middle childhood, and 1.2 SD into early adulthood.

>About 37% of Blacks have an IQ below 80, while only 9% of Whites do. Blacks are 6x as likely to have an IQ of 70 or less as Whites, 12% of Blacks compared to 2% of Whites. Half of Whites have an IQ over 100 (average) but only 16% of Blacks do. Only 1% of Blacks have an IQ over 120, but 9% of Whites do.

>The ASPM gene of Chromosome 1 has been shown to effect brain morphology and defects lead to smaller brains and low IQ.

>The MCPH1 gene of Chromosome 8 with alleles known as "microcephalin" partly determine brain size and morphology
http://hmg.oxfordjournals.org/content/13/11/1131.short

>Beneficial alleles are common in Eurasians but rare in Blacks. The MCPH1 and ASPM gene correspond with the development of hand-crafts and the development of sophisticated cities which were common in Eurasian populations but unheard of in sub-Saharan Africa.

>One alelle results in dyslexia
http://www.pnas.org/content/102/47/17053

>"The allele frequency of the A allele rs2274305 of the dyslexia-gene DCDC2 is about 0.28 among Eurasians and 0.99 among Yorubas from Nigeria, about 0.80 among African-Americans."
http://www.v-weiss.de/majgenes-full.html

>The DTNBP1 gene has also been linked to intelligence, specifically the rs:760761, rs:2619522 and rs:2619538 alleles. For rs:760761, 18% of Whites carry the T allele, which takes off 8 IQ points, compared to 37% of Blacks. For rs:2619522 carrying the G allele takes off 7 points, and is found in 18% of Whites and 35-36% of Blacks. The rs:2619538 T allele increases IQ by 6.5 points and 61% of Europeans carry it vs 67% of Blacks.
