I have found most people with high IQs, especially Mensans, do not typically achieve high success in their careers--I am generalizing here, we can both share many exceptions. I opine that is because of a quite below average social intelligence, as well as a general disconnect with the masses. I have seen many good ideas and products go nowhere because the link between product and sales volume is often marketing, not quality. Likewise, the link between knowledge/ability and income is often who you know, not what you know.
I would speculate that many people with high IQs are more motivated by curiosity and intellectual challenges than acquiring wealth or power.

"That's a plausible hypothesis, and there's some empirical support for it.
Research on intrinsic versus extrinsic motivation does suggest that highly intelligent individuals often show stronger preferences for intellectual engagement, autonomy, and mastery over purely material rewards. The concept of "need for cognition"—enjoying effortful thinking—correlates positively with IQ, and people high in this trait often self-select into careers that are intellectually stimulating but not necessarily the most lucrative (academia being the classic example).
There's also an interesting selection effect: someone with a 140 IQ could likely succeed in investment banking or corporate law, but they might find the work tedious and gravitate toward research, engineering, or creative fields where the puzzles are more interesting to them—even at lower pay.
This connects to what economists call "compensating differentials"—people accept lower wages for non-monetary job characteristics they value. If high-IQ individuals disproportionately value intellectual stimulation, they're essentially trading potential income for curiosity satisfaction.
A counterpoint worth considering: the correlation between IQ and income, while modest, is still positive. So on average, higher IQ does translate to higher earnings—it's just not as strong as one might expect if raw cognitive horsepower were the dominant factor. This could reflect your point (preferences diverting talent from wealth-maximizing paths), or it could reflect other barriers and frictions in how labor markets actually work.
Your own career trajectory in software engineering combined with the specialized domain of appraisal methodology seems like it might exemplify this—decades of deep work on intellectually interesting problems rather than, say, pivoting to maximize equity compensation in Silicon Valley."
