Recently I got a private question from anon: A quick question if you don't mind: how come Blacks from sub-Saharan Africa have an average IQ of 70, which is even lower than that for Blacks from the United States (85)? Shouldn't it be the case that both of these groups have a similar IQ? After all, both Blacks from Africa and Blacks from the US originally come from the same continent. Or am I missing something?
Emil, is it good to assume regression coefficient is 0.5? The wiki article says Galton estimated coefficient as 2/3 for height, what is it now? Could it be that in Galton times coefficient was higher because environmental factor was more important than it is now?
Another plausible explanation for the overperformance of African immigrants relative to African Americans: severe dysgenic fertility among African Americans. It's not clear how long AA fertility has been dysgenic, but given the extremely un-Malthusian nature of the colonial era US, it's possible that it's been hundreds of years of selection for lower IQ, severely accelerated by the 1960s Great Society programs and consequent disintegration of the black community. Since a large chunk of African American ancestry is Igbo or Yoruba, both of whom have comparatively successful modern diasporas, I don't think the Igbo or Yoruba being smarter then the average SSAfrican is enough to account for their diaspora's higher performance compared to African Americans. I also don't think selective immigration can explain the whole gap: there aren't enough +3.5SD Nigerians to account for the widespread success of their diaspora, and presumably not every single highly capable Nigerian emigrates (and some more typical Nigerians also emigrate).
Also, I think the calculation in the toy example of offspring of African migrants to America is wrong. The average genetic potential of the parents is (120+10-80)/2+80=105. So the parents would have 130 IQ if they had been raised in America, and 25pts of those 130pts would have been due to positive environmental luck, instead of the measly +15 environmental points they got in Africa (depressed by 10pts on average). So their offspring are expected to have phenotypic average IQ of 95 in Africa, and 105 in America.

This disadvantage is removed for the children who grew up in the USA. So the predicted IQ is not 95, but 110 (halfway to 80 from 120 is 100, +10 for the removed disadvantage
I read it three times and failed to understand. Where is this "plus 10" comes from? The 80 IQ already removes any environmental disadvantage.
Also, does it really make sense to say that smart parents usually have children that are less smart than them? I am not sure it is how the world works.

Typo: "75+25=95 IQ" should be "70+25=95 IQ"

This disadvantage is removed for the children who grew up in the USA. So the predicted IQ is not 95, but 110 (halfway to 80 from 120 is 100, +10 for the removed disadvantage
I read it three times and failed to understand. Where is this "plus 10" comes from? The 80 IQ already removes any environmental disadvantage.
Also, does it really make sense to say that smart parents usually have children that are less smart than them? I am not sure it is how the world works.
Why is it that only additive genetic effects are passed on to offspring, and not non-additive genetic effects as well?
