This feeds into one of my pet hypotheses about human ability: the most important biological factors determining success lie not in whatever influences IQ or other intelligence or creativity attributes but in the dopamine system. Take 20 IQ points from someone and replace that with the ability to engage focus and flow state at will and see what happens. Our dopamine system is tuned for a world that is far slower than…
Nothing can replace intelligence potential, i.e. IQ, because it's a prerequisite for a lot of activities. Just like the height in the basketball.
I imagine if time was not a factor, then scores would be quite different. Life is usually less time constrained than some proprietary, standardized test, so I think you might be surprised at what people with "normal" IQs could accomplish if properly motivated, engaged, etc..
Then again, it's not like IQ is the be-all and end-all of intelligence measuring. It's just the (debatably) best we have now.
Also, plenty of people with extraordinary IQs accomplish absolutely nothing of value in life, awful social skills, etc.. Hell, I had a professor once that while rather arrogant about her IQ, would also claim that having an IQ as high as hers is actual a disability -- you struggle to relate with people. Von Neumann didn't have that issue, but hey, everyone is different.
