Oh did I? Or perhaps geography leads to cometic differences.
I see. Can you explain why those differences have to be cosmetic? I see no reason to presume so. ('It would be so
awful if they weren't' isn't really a good enough reason, I'm afraid.)
Also, you'd have to be a total and utter crackpot to not know that IQ and "conscientiousness" (lmao if I ever heard of a subjective term) are largely cultural factors. IIRC a 100 IQ today is the equivalent of 115-120 IQ of someone from 1900. People aren't getting genetically smarter... We know that the stereotype threat is a hugely significant factor in the world and that when you control for it, or preempt it, IQ scores from underperforming groups end of bridging much of the gap. You justification for IQ differences based on race is laughable.
Sporting differences and differences in disease potential are in fact largely cosmetic. Controlled for wealth, social interaction, and other cultural factors, everyone lives about 90 years and is just as capable of success as anyone else.
In a world where you can make up your own facts, anything is possible. The above post inhabits such a world.
First of all, the winning of hearts cannot be done by calling a man a 'total and utter crackpot', nor the winning of minds by displays of colossal ignorance.
In addition to the summary I linked to in the beginning (if it doesn't satisfy you), there is in addition the Wikipedia article on IQ (and its heritability of around 0.85, as concluded from a meta-analysis) and the 'big five personality traits', one of which is
conscientiousness (heritability 0.49). (I expect that as the definition of conscientiousness gets clearer, and testing for it becomes more reliable, its heritability will be seen to increase.) Unless there is any solid data to back the 'culture' hypothesis, it would be wise to drop that ritual incantation; its efficacy has been exploded by the data.
The Flynn effect, interesting enough, cuts both ways. Yes, people's scores on IQ tests are rising. No, it doesn't negate the racial differences that existed in the scores to begin with; a rising tide lifts all boats. The mechanism is not yet fully known. And it appears that the effect is plateauing. Further, given the heritability data above, your statement that 'we are not getting genetically smarter' has nothing whatsoever to support it. (Nor does it have anything to oppose it, mind you; it's a naked assertion.)
Even when you control for everything that you have said, the racial gap in IQ remains. Stereotype threat fails completely at explaining this observed difference. Feel free to laugh at over seventy years of meticulously collected data is that is what you find laughable. The SSSM has no legs left to stand on scientifically; it is only the other implications of its abandonment, and the desperation of those that have been its supporters for so long, that keeps it going.
Regarding differences in sporting ability or disease propensity being 'cosmetic', I would disagree. Sickle-cell anaemia is no small matter. Nor are treatments which work well for one race but not that well for others (yes, they exist).
Finally, as for the 'controlled for everything, everyone is equal' assertion, it is very naked and
actually laughable. The studies that have actually controlled for the factors you mentioned have come to the conclusions that a) there are significant and persistent (statistical) racial gaps in intelligence, conscientiousness, criminality, and a host of other traits, and that b) the heritability of these traits is high, and c) on many of these traits, culture makes next to no difference. The poster-child for this is IQ (more specifically,
g), because it is the most heavily studied.
