Does anyone know of a good overview of the Race and IQ debate for someone who's completely ducked the topic until now and is basically ignorant?
EDIT: Thanks for the responses everyone!
People who are see-no-evil-pilled typically need a quick introduction of why anyone would even think races might have varied intelligence. A quick (outdated by now) copypasta that used to get posted:
And now for refutations. The most common response to the above syllogism is that whites in America have a shared environment. As such, things like twin studies and adoption studies which purport to show IQ as genetic, actually only show that a smart white child adopted by dumb white parents still benefits from a community and culture that cultivates their intelligence. (Systemic Racism).
For the most interesting refutation of a black-white intelligence gap, read the series of articles Chisala Chanda wrote for the Unz Review. A large part of his argument is that modern transplant populations from Africa to the UK and USA, as opposed to the descendants of slaves, do not show an achievement gap with the native populations.
EDIT: I should clarify that I'm not versed in the latest state of the art in this debate -- I made my conclusions about ten years ago now and don't find the topic that interesting, except as an example of ideological constraints causing otherwise rational societies to act in incredibly stupid ways.
There's an old meme that the best way to get help for Linux is not to ask for help on X, but to publish an overly-confident flawed diatribe about how Linux sucks because it can't do X. I suspect Race IQ debates work the same way.
I am skeptical of the race and IQ narrative mostly because Africa has an average IQ so much lower than everyone else. It's fairly easy to come up with just-so stories about Europe and East Asia. But nearly the entire world, including the pure indigenous populations of the Americas, scores notably higher than pure blacks do, on average.
It seems like the answer is as much about "the places where blacks with no European ancestry are to be found are extremely badly run societies with very high rates of child malnutrition and a high parasite load, and this depresses IQ scores. This problem is shared with a few other areas that are not majority black, but purely black populations probably have an average IQ similar to the averages in southeast asia and among native americans, while east asians and most whites underwent selection effects for higher IQ" as it is about genetics. Unless there's some selection effect for all nonafrican populations but not subsaharan africans that I've missed(and before "Ice age", humans were already pretty widely dispersed by then).
To put it another way, it doesn't pass my smell test that every population not considered black scores higher than every population considered black with no white admixture, when neither are monogenetic groups in ways that the entire human race is monogenetic.
Could you rephrase this? It sounds interesting but reads to me like "I'm skeptical of HBD because every single black country has a low IQ, and every black minority population in other countries also has a low IQ." To me this sounds like pretty good first-glance evidence that the HBD story makes sense, even before you look at the genes themselves. Forgive me if I'm tired and completely misreading you.
Could you give a few examples? I'm under the impression that the IQ in say, Afghanistan, is quite high despite the institutions in those areas being incredibly dysfunctional forever. (EDIT: Woah, dead wrong alert. Afghanistan looks to be in the mid eighties. This table looks to be sourced to Richard Lynn's work.)
I left this out because it's pure speculation, but the "Cold Winter" hypothesis is the one you run into the most. Populations incapabale of planning many months into the future died off any time their migration crossed a temperate climate. For example, this also explains why Mesoamerican civilizations which were also tropical or subtropical have such a high IQ and had sophisticated premodern science and maths. (Their ancestors had to pass through Siberia and over the Bering Strait.)
Nepal, Guatemala, and Nicaragua are the three non-black countries in the bottom ten in the world by IQ score. All three are desperately poor, badly run countries that plausibly have environmental factors causing loss of IQ points in kids that grow up there. And really 7/10 countries being African sounds not too far off from a sample of 3rd world countries.
The main thrust of my argument is that since non-black is not a monogenetic group, and black isn't either, the pattern of every non-black group outperforming every black group demands an explanation. I'm aware of the cold winter hypothesis, and that's why I included southeast asia- why does the dumbest country in SE Asia(Indonesia) have an average IQ roughly on par with the smartest country in subsaharan Africa(Sudan)? Since we know that childhood malnutrition and parasite burden and all sorts of other things black countries usually do badly on lower IQ, it accords with available evidence to suggest that the average IQ of blacks would be in the eighties if they lived in countries that were as nice as Thailand or the Philippines. To my knowledge, it doesn't require a cold winter to reach either of these countries from Africa, and neither of them has undergone some kind of selection effect for high IQ, and if anything biased sampling probably makes Africa look relatively better than more urbanized SE Asian populations rather than explaining the gap.
All of these countries had quite dark-skinned populations several thousand of years ago. Then, populations originating from territory of modern China came and largely displaced them, sometimes without a trace of preceeding population. A large fraction of area of modern China was permafrost or under glaciers at some point.
Why do you think Indonesians literally living at equator have such light skin?
A diet based almost entirely on rice would tend to lighten the skin over generations, but the Chinese replacement also makes sense.
In general, it almost never occurs that some recent non-African population had its ancestors follow shortest path from Africa.
