I deny that there are any sort of reliable genetic markers for race that also show correlation with the genetic markers for IQ. The are genetic markers for geographical populations, but populations do not map cleanly onto racial categories in America.
Where did White Americans come from? Why have White Americans always been seen as distinct from Black Americans?
It's just not possible to believe White people have never been their own racial category.
And again, there's an easy way to prove your theory. Get a large sample of self-identified African-Americans. Those with higher %s of European DNA should presumably do better on IQ tests because according to your theory IQ is essentially a linear equation matching to geographical origins. I would bet that test would fail miserably.
We know the IQ of Africans native to the continent have averages in the 60 ~ 80 range. That little bit of European admixture is theorized to give Black Americans 5 ~ 10 more IQ points than Africans.
Additionally, the average IQ was not taken from elite African schools as per the criticism you link, which was actually written by a biochemist, not an IQ scientists. In fact the board for Intelligence Research removed him due to his incompetence in analyzing sub-Sahara African IQ. And in fact the paper already addresses this criticism to begin with:
Anyway, the average is widely agreed to be 80 for sub-Saharans, and this gap can be explained through environmental factors just as well as any genetic theory you'd like to support:
Also, don't quote me on this yet, but I'm pretty that this study exists. I once read that White Americans who were tested for IQs in the 80 were found to be less functional and struggle to keep up. However, Black Americans with IQs in the 80 were shown to be more "normal".
I believe this study came from the army, because they do have a cutoff limit for those who cannot follow instructions correctly.
2. Flynn effect is misunderstood. Humans weren't less intelligent 50 years ago. You need to compare the scores with other scores at that time.
If the Dutch scored 50 points, you need to compare the African equivalent in the same timeframe, not today.
3. It is very unlikely environment or wealth is to blame for Africa's IQ.
Again, every white country that is rich or poor still have averages in the 100 range. Mongolia, a poor country in East Asia, still scores higher than all of them.
There has never been an exception where a majority country of African descent had the same average IQ as European or East Asian countries.
You still didn't answer my question. For the third time, do you agree with this statement: "Centuries of racism has nothing to do with black achievement and wealth, it's just that they're naturally low intelligence and can't achieve much more than what they're already achieving in the US."
I do not think racism or oppression is exclusive to black people. All races have been oppressed or discriminated at some point in history.
