Do you believe the average is is (about) 76, or do you no longer believe this, and now believe it is closer to 70? 76+12-15 would be more than 82.
Do you no longer agree with what you stated here?
“US Blacks have a 15 point gap to close between Blacks and Whites. That is quite a bit more than the 8 points that separated Bermudian Blacks and Whites. However, if Bermudians could close the gap by 8 points, perhaps it is not beyond the capability of US Blacks to close the gap by a similar amount. US Blacks would certainly function a lot better at 93 IQ than at 85 IQ.”
This would seem to imply a potential IQ of Africans of about 90 or so.
There is also the Bahamas score.
I am not certain the 86 figure for UK blacks is reliable (at least for UK born blacks, and those arriving before adulthood). The achievement test data on g-lodes tests (which correlates with IQ from the UK CAT at matched ages, and does not tend to show a widening with age) seems to suggest otherwise.
What was the Bahamas score again? ~90?
Those Bermudian Blacks are half-White. Obviously there will be some dramatic effects, mostly positive, on a Black population that becomes mixed to a 50% White level. Differences in achievement, drive, aggression, reactivity, impulsiveness, forward thinking, planing, time preference, responsibility, inhibition, and all sorts of things. Perhaps there is something special about Blacks who are half White that enables them to get jacked up enough to match Whites on an IQ test. A 50% White population of Blacks is going to be so different than a 100% Black population of Blacks that there is almost no comparing them.
On the other hand, the behavior of mulattized populations in Guyana, Mexico, Dominican Republic, Puerto Rico, Brazil, Venezuela, and Colombia is not very impressive.
I am not sure that mulattization is a way forward for Black people, though there are clearly some benefits to Blacks in obtaining White admixture.
