I wonder if such studies are susceptible to bad stats of confirmation bias as many business studies are.
What I mean is whether they had proper controls to assess whether each average person is more likely to succeed than each "smart" person given the same scenario.
If they instead took a bunch of successful people, figured out that a lot of them weren't that "smart", then it could be the product of there being a lot more average than smart folk. In other words, "smart" doesn't guarantee business success such that all successful businesspeople are IQ gods, but we all knew that.
