1) @RazibKhan : As usual, excellent piece. Thank you.
One Issue to add to the beginning: Neotenic evolution continued after 200K YBP, producing domestication syndrome, deeper prefrontal cortex development, and impulse regulation by suppression of aggression.
You are correct in that brain size (and digesive system) are at near biological limits (even if we have found the genes for heart, lungs, and accumulation of lactic acid, meaning that we can have far more durable humans at no cost – the end point of persistence hunting.)
But evolution made great leaps of about a standard deviation with each of the speciation events made possible by isolation, and then territorial expansion.
In other words skeletal structure, aside from the race differences caused by neoetic expression, does not reflect the superiority of self regulation caused by domestication, a side of affect of which is – decrease in size, shallower sexual maturity, a longer life span and more demonstrated intelligence. A lot more.
2) IQ vs income is a ‘nitwit’ measure, since (a) conscientousness is more determinant of wealth regardless of IQ (across the spectrum) than IQ is. (This is where Taleb gets it wrong). (b) Income increases depend on the number of people you can effect returns from which for any number of reasons decreases as IQ increases. This should be rather obvious but I’m surprised out infrequently it’s considered. (c) many vary bright people find that they need very little money to pursue their intersts, precisely because it requires satisfying large numbers of people, who do little but distract from the bright person’s ambitions. In other words income and consumption value are not constant over the IQ spectrum. (I was far happier in an apartment in Kiev working on a think tank than I ever was as a CEO of a $100M tech company – although I do miss my ferrrari farily often.)
3) Three traits our organization keeps identifying consistently: IQ, Conscientiousness, Disagreeableness. Surprisingly disagreeableness is more important than conscientiousness.
I probably have more flexibility than do others to address these matters. And I understand why you (collectively) don’t. That said, implying as you do, results
