Also worthy of note: whatever IQ measures, second and third-generation immigrants to First World nations from Third World ones have more and more of it.
Yet at least in the case of those of African ancestry don’t seem to ever catch up. Those of East Asian ancestry don’t seem to ever drop to European levels either. It makes perfect sense that lower exposure to parasites and better nutrition will boost IQs for quite some time. Since stupid people generally earn less, this means their children get to enjoy fewer of the benefits of a good envrionment.
Remember even Lynn, Jensen, ect., the scientists favouring the hereditarian hypothesis consider a 50-50 split between genetic and environmental factors to best match their data. Their opponents claim it is nearly all envrionment.
I’m pretty much certain Askenazi Jews are smarter than gentile Europeans because of genetics. I’m also very certain that East Asians are smarter than Europeans because of genetics. The IQs of these groups have been measured in environments that appear to be as optimal as we can make them.
I’m not so sure where South Asian and Middle Eastern IQs would lie under 1st world conditions but if I had to make a guess I’d say the difference in intelligence is probably comparable to the difference between Europeans and Asians, putting their average somewhere in the mid 90s.
I’m also unsure how much of this low IQ is just the result of inbreeding, which is something “easily” fixed. It seems very plausible that the European vs. Middle Eastern gap can entirely be explained by different levels of inbreeding.
African IQs until quite recently seemed very firmly and robustly one standard deviation (15 points) below the European average, but there’s recently been some strange educational achievement data from the UK, which suggests the difference may be as low as half a standard deviation. Low 90s quite honestly seems a stretch considering all the other data though, so my best estimate is in the 80s. Which also happens to be about right considering educational attainment of second generation immigrants elsewhere in Europe and African Americans.
