Despite its success, the Uber-LWer is still making less money than the Uber-HighIQer. (Perhaps people are overreporting their IQ. Or maybe there's some social consequences to rationalism. Or maybe the career paths of LWers tend to be lower paying. Not sure what to make of this one.)

IQ doesn't change much over the lifetime, being an LW'ler does. Decisions that you made ten years ago might determine your current salary.
