I think you're onto something here. A person who graduates from technical program of good university, but then falls for the first Ponzi scheme and starts selling vacuum cleaners? Not very smart. It's like he has very good processor able to run any math problem you throw at him. But at the same time he doesn't independently do very good job of discerning what is relevant and what is not. On the other hand some of the greatest scientists of all time have been able to maintain certain "what if" state of mind for years. Doing quick and accurate true/false analysis is often a trait of street smarts, but the most genius of all seem to be able to play with probabilities.
