Black-White IQ Differences are Significantly Genetic

Rebutting My Opponent's ArgumentsImportance of IQ My Opponent first claims that: "Firstly; the basis for your argument is flawed. Many scientists deny the effectiveness of the IQ". I don't know exactly what his point is here. Although I believe that IQ is a very important for life outcomes, that is not the topic of this debate. This is about the Black-White IQ gap, and it's cause. The IQ test is meant to measure intelligence. And, not all fields require the same intelligence to be an expert in. My opponent says: "So; is it fair to say that a white physicist is cleverer than a black artist? "I would say that a Physicist of any color is most likely smarter than a Artist of any color (in most cases). Evolutionary HistoryMy Opponent says:"All Homo Sapiens Sapiens originated in the Rift Valley in Africa some 50000 years ago. This too suggests that all races have the same intelligence as no great evolutionary change happened after this time. "This does not suggest that at all. The article my opponent linked actually does more to hurt his point and help mine. Here is a direct quote from the article my opponent linked to:"That's because populations built up genetic and physical diversity for some 150,000 years before the fossil record suggests the first pioneers started spreading elsewhere. " This means that the researchers of this point believe that there is a lot of genetic diversity in the world. Even more importantly, the article points out that those that descend from Europe are very genetically different those from Africa. The article my opponent cited is actually a point for the Genetics side of this debate. Black Race "Finally; 'black' isn't a race. Are you suggesting that every-one who has black skin is intelligently inferior or are you suggesting that only black, first generation Africans are intelligently inferior? "This is not at all what I am arguing. I am saying that, on average, blacks have a lower intellligence than whites. Many individual blacks are very smart. As far as race goes, I am talking about Americans largely descended from Africa, the traditional definition of African American. My ArgumentsA 60 page review of scientific evidence found that racial IQ differences were genetic, based on: "The Worldwide Pattern of IQ Scores. East Asians average higher on IQ tests than Whites, both in the U. S. and in Asia, even though IQ tests were developed for use in the Euro-American culture. Around the world, the average IQ for East Asians centers around 106; for Whites, about 100; and for Blacks about 85 in the U. S. and 70 in sub-Saharan Africa. Race Differences are Most Pronounced on Tests that Best Measure the General Intelligence Factor (g). Black-White differences, for example, are larger on the Backward Digit Span test than on the less g loaded Forward Digit Span test. The Gene-Environment Architecture of IQ is the Same in all Races, and Race Differences are Most Pronounced on More Heritable Abilities. Studies of Black, White, and East Asian twins, for example, show the heritability of IQ is 50% or higher in all races. Brain Size Differences. Studies using magnetic resonance imaging (MRI) find a correlation of brain size with IQ of about 0.40. Larger brains contain more neurons and synapses and process information faster. Race differences in brain size are present at birth. By adulthood, East Asians average 1 cubic inch more cranial capacity than Whites who average 5 cubic inches more than Blacks. Trans-Racial Adoption Studies. Race differences in IQ remain following adoption by White middle class parents. East Asians grow to average higher IQs than Whites while Blacks score lower. The Minnesota Trans-Racial Adoption Study followed children to age 17 and found race differences were even greater than at age 7: White children, 106; Mixed-Race children, 99; and Black children, 89. Racial Admixture Studies. Black children with lighter skin, for example, average higher IQ scores. In South Africa, the IQ of the mixed-race "Colored" population averages 85, intermediate to the African 70 and White 100. IQ Scores of Blacks and Whites Regress toward the Averages of Their Race. Parents pass on only some exceptional genes to offspring so parents with very high IQs tend to have more average children. Black and White children with parents of IQ 115 move to different averages--Blacks toward 85 and Whites to 100. Race Differences in Other "Life-History" Traits. East Asians and Blacks consistently fall at two ends of a continuum with Whites intermediate on 60 measures of maturation, personality, reproduction, and social organization. For example, Black children sit, crawl, walk, and put on their clothes earlier than Whites or East Asians. Race Differences and the Out-of-Africa theory of Human Origins. East Asian-White-Black differences fit the theory that modern humans arose in Africa about 100,000 years ago and expanded northward. During prolonged winters there was evolutionary selection for higher IQ created by problems of raising children, gathering and storing food, gaining shelter, and making clothes. Do Culture-Only Theories Explain the Data? Culture-only theories do not explain the highly consistent pattern of race differences in IQ, especially the East Asian data. No interventions such as ending segregation, introducing school busing, or "Head Start" programs have reduced the gaps as culture-only theory would predict.
