It should not be assumed that the genetic potential IQ is ca 80. If a measured IQ of 75-77 (or 81 if Wincherts is correct, to say nothing of if Afro-Sapiens is correct, which I do not know) is suppressed by disease load and malnutrition by about 15 points (which even Lynn believed), potential IQ’s could generally be closer to 90, or the low-mid 90’s (in some cases).
Forget it. Wincherts is as bad as Lynn when it comes to throwing out studies. I think if you leave all the studies in and average them all together, African IQ is ~76. I forget the exact number. There is no way on Earth Africans have a potential phenotypic IQ of ~90-94, forget it.
In addition, we continue to regularly receive reports of IQ studies out of Africa where the Blacks are scoring ~70 or even lower. That is simply a catastrophically low IQ. Personally I feel that in any group that regularly turns back IQ scores of ~70 has horrible problems. There is no way that a group with potential phenotypic IQ of 92 is going to get scores ~70. It’s just not going to happen. Even in the catastrophic environment of South Asia (often regarded as worse than Black Africa in many ways) the horrific environment only depresses national IQ’s down to ~80. A group that continues to turn in IQ tests scoring ~70 has some very serious genetic IQ issues I am afraid.
I do believe that the Black African IQ is ~70 at the moment. The horribly failed and collapsed nature of the so-called states over there definitely makes sense if note that this is the sort of failed state a 70 IQ population may well produce.
The most intelligent natural Blacks nationwide populations in the whole world are in the US and the UK.
Black IQ in the US = ~85, though you can get 87 if you fiddle around and throw out studies.
Black IQ in the UK = 86.
US Blacks are 20% White. There’s 6 IQ points right there + 9 points for improved environment.
UK Blacks are 13% White. There’s 4 IQ points right there + 12 points for improved environment.
For pure US Blacks, 85 – 6 = 79 IQ.
For pure UK Blacks, 86 – 4 = 82 IQ.
It looks like pure Black phenotypic IQ in Africa is going to top out at 81.5 IQ.
However, if the Black African IQ could be raised from ~70 up to ~82, I think that would be cause for celebration. A 12 point IQ rise in a population is nothing to shake a stick at. And Africa would be a much better place for the Africans and for the rest of us for that matter as African failed states impact all of us.
In fact, I think the Africans might do better than the South Asians.
