This. There's nothing scientific about Watson's views, and even social scientists who stress the relevance of cognitive skills in development and express concern about this relevance (such as, IIRC, economist Garett Jones) do not share or endorse a view nearly as extreme as Watson's. Even journalist and pundit Steve Sailer, who is very often ridiculed as a believer in scientific racism, has actually stated many times and with great clarity that even "raw" cognitive ability (to say nothing of things like educational attainment or productivity) is extremely likely to be highly affected by environmental factors such as severe disease, malnutrition and the lack of a range of important micronutrients-- such factors being very common in Africa and in low-income countries more generally, but also obviously amenable to change. This whole Watson kerfuffle is just a cranky old guy sharing his deeply misguided opinions-- it's not science and it's not even "scientific" in any real sense.
