Even the maximalist (and implausible in light of other data) Rushton-Lynn hypothesis
I’ve been looking for about a decade now, but have not encountered evidence that would discredit Lynn. I have however seen a lot of evidence which corroborates his findings.
If you have evidence that discredits his work, I would appreciate it.
is perfectly consistent with aid (external provision of disease treatment, etc) having massive benefits in reducing disease and increasing wellbeing until biotech or more radical things can bypass any genetic disadvantage.
Why stop at Africa then? Shouldn’t we invest billions in animal shelters, so that dogs and cats can live long lives until we find a way to bypass their genetic disadvantage? Wouldn’t those be just as “massive benefits”?
And there’s no need to be smug.
Perhaps it came across as smugness, but I do find that every piece of news I see, either from South Africa, or from Haiti, or from Nigeria, or from Zimbabwe, or from Turks and Caicos, just adds to the pile of evidence.
Also, I myself live in a place like that. Which is why I suggest (in all seriousness!) that people should consider visiting a country like South Africa for a while.
There’s no better cure for academic distance than direct contact with the hard facts on the ground.
African-American IQ in the 80s, with only 20% European admixture, shows that African IQs are depressed by environment. The Dickens-Flynn model explains how to reconcile the Flynn effect and heritability increasing with age: gene-environment interactions, suggesting that any genetic difference would be amplified by feedback environmental effects. Even Jensen gives a chunk of the gaps to environment.
Animals have short lives so it wouldn’t work well, and I care less about them than people with long term plans hopes and fears.

I wouldn’t say so. I think it shows that genes for higher IQ are inherited dominantly.
This has also been proposed as an explanation for the Flynn effect—whole countries getting “smarter” over time—being due to the gene pool mixing more in cities, and thus with dominant pro-IQ genes gaining ground.
The same mechanism has been proposed for the increasing height.

See, that’s fine with me. You want to indulge in X because you like it, not because of rationalization Y or Z. Just like I want to indulge in chocolate. That’s fine with me.
I just don’t like the claim that it is morally superior. Or that it’s something everyone should do. Or that it’s how resources “should” be spent. If it is an indulgence, though, then indulgences are fine with me.
Btw, I’m just going to interject and say that this conversation has been done at Hacker News many times and it never really goes anywhere. I’m going to wait five years until more genome wide association studies are done before I try to enter this argument again. It seems obvious to me that there are some genetic differences in intelligence, but it’s a touchy enough subject that I don’t feel it’s worth entering an argument based on individual interpretations of incomplete evidence.
