UK African blacks according to Lynn had an IQ of 86. Recent scores on the CAT for the children of UK Africans put them at ~94.
How old were these children who scored 94, and what is the CAT?
My information is that yes, some groups of UK Blacks are doing very well on IQ as children. In fact, one recent study found that very young UK Blacks (age 6) were scoring as high as 106 on IQ tests. However, testing of adult UK Blacks shows them at 86, so apparently these children are crashing down from 106 to 86. Scores following British children by age shows them slowly crashing back down from 106 or wherever down to 86 by age 24. I do not know what is going on here, but early gains do not seem to be sustained for some reason. Does anybody have any idea how a Black child in the UK scores 106 (!) on an IQ test but then crashes all the way back down to 86 by age 24. That’s seems so odd.
Also the 86 score is only for UK Blacks born in the UK. Their parents or grandparents who were born in Jamaica continue to score 71, the same as they did in Jamaica.
However, somehow their children got a 15 point IQ gain simply by being born in the UK. Does anyone have any idea how that could be possible?
