Nassim Taleb is likely wrong about IQ and talent

Taleb is right in probably a strict sense — there is diminishing marginal returns to intelligence if the standard of success is wealth.

For any given task, I would expect ability = f(IQ) to be a logistic function, because everything is a logistic function.

Income is a result of supply and demand.

IQ is by definition a normal distribution, which defines what the supply is.

But, what's the demand? If there just aren't many tasks (relative to supply of smart people) where the linear region is at or above say IQ=150, then increasing IQ above 150 shouldn't increase income.

if you want to want to be a billionaire before 35, it seems like a preq. having an iq above 150. Look at the founders of Google, Facebook, etc. It was like this in the late 90s too except put the cutoff at $100 million and instead of apps it was websites, IT. If you want to completely master a new and complicated technology at an early age, i don't see how there is an IQ ceiling.

I've not seen a study that doesn't top out too low to confirm or refute that.

Why do you think that?

Probably because very high levels of intelligence correlate with interests that aren’t super compensated in a pecuniary sense (eg pure math). Being 130 IQ with a great work ethic and not super interested in technical skills might play better than 145 IQ.
