I know right? We jump from > how much of the difference between people’s incomes can be tied to IQ to > So if IQ is only a minor factor in success, what is it that separates the low earners from the high ones? The second doesn't follow at all. Lots of evidence suggests that beyond a certain baseline, income is almost uncorrelated to happiness, and I wouldn't be at all surprised to learn that the highest income earners are less happy for the life they've chosen. I would not categorize that as success. If you're smart, and not crazy, your goal isn't to maximize your income.
