The heritability of intelligence is now well established from numerous adoption, twin, and family studies. Particularly noteworthy are the genetic contributions of around 80% found in adult twins reared apart. And most transracial adoption studies provide evidence for the heritability of racial differences in IQ. For instance, Korean and Vietnamese children adopted into white American and white Belgian homes were examined in studies by E.A. Clark and J. Hanisee, by M. Frydman and R. Lynn, and by M. Winick et al. Many had been hospitalized for malnutrition. But they went on to develop IQs ten or more points higher than their adoptive national norms. By contrast, the famous Minnesota Transracial Adoption Study marked black/white differences emerged by age 17 even though the black children had been reared in white middle-class families (Weinberg, Scarr & Waldman, 1992).

> unless you take a statistically significant number of babies from parents of different races (and choosing who to take from adds yet another layer of complexity), raising them all in the same environment, you are not going to be able to remove certain environmental variables that affect intelligence differently among the races.

>Is there any evidence of actual intellectual superiority tested before the subject was constraint to environmental and societal factors that would without a doubt alter his perception or potential capabilities?

Yes, involving black children raised in upperclass white families tested against whites from poor families. The gap was reduced, butremained significant. Pic related.

I've long since accepted that those afflicted with the "everyone is identical and genes have nothing to do with intelligence" crowd will never consider evidence that conflicts with their views, but I guess I've got to hold up my side of the argument on principle. :I

do you fell that you are superior to the blacks by virtue of the fact that you are white, and that no matter how intelligent or accomplished a black man is he could never be as valuable as you?

if so you're a racist.

If you only think that the average black is inferior to the average white but that there is a spectrum in both races then you are not someone I would consider a racist but some people might.

if intelligence differences merely arose due to culture we wouldn't see this

>biracial breeding produces genetically superior offspring

Nope.jpeg

Hybrid vigor has no relevance to the discussion of breeding across human racial lines. I am not sure why anyone got the idea that it did.

Mongrel children score, unsurprisingly, between their two parent races. So a white/black hybrid will in just one generation have dropped a half a standard deviation in IQ when compared to fully white siblings or ancestors.

When you consider that intelligence is by far the most important human trait it would be hard to make a legitimate argument that dropping your intelligence so drastically in just one generation is somehow beneficial. Ultimately your goal should be to increase the fitness of your offspring. Breeding with Whites is certainly beneficial to Negroes, but not to the Whites who are breeding downwards.

the label "liberal creationists" is misleading but the chart os pretty cool

>if you take a bunch of new born whiteys darkies, have them grow up in the same enviorment and give them equal education, would any one group do better on average in an IQ test?
I'm glad you asked.
