Woh, I did allow myself to misread/misremember your initial comment a bit so I'll dial it back slightly. The fact that even at the highest levels IQ is still positively correlated to income is important, and its what I would have expected, so the overall story does not undermine my support for the hypothesis that at the highest IQ levels, higher IQ individuals produce more positive externalities. I apologize for getting a bit sloppy there.

I would guess that if you had data from people with the same job description at the same company the correlation between IQ, patents, and income would be even higher.
