>>11901005lmao, are you unironically quoting the Alternative Hypothesis to me? That's a far right propaganda site, retard.
Looking up your link, their "Hereditarian prediction" is calculated by using the IQ scores of Indians in the UK in the present (wtf) as a proxy for North Africans in the 1950s study, and using their "results" as "proof" that the Eyferth study was "not that far off" from what a hereditarian "would predict".
Nevermind the fact that using Indians as a proxy for North Africans makes no sense whatsoever because they are totally unrelated populations, that North Africans were only a fraction of the sample of fathers, and that you cannot use modern IQ scores from the UK to extrapolate results about the 1950s. Also, no sources are given. That link is absolute garbage.
>>11901009OK let's assume you are right, and that somehow ALL Africans in the UK magically belong to the smartest 2.2% of Africans that are two SD above average, let's assume they are all highly educated professors with college degrees and PhDs even though that's obviously not the case, that not a single African from the remainder 97.8% immigrated... assuming all that, you would still have to explain away how is it that second generation Africans in the UK score considerably higher than their parents and grandparents. The predominance of environmental factors is self-evident and undeniable.
