Quote from lolatency:
We all complain that stupid people don't realize they are stupid. Well, suppose there is a man who is stupid and he wakes up one morning and realizes he is stupid. He's been faking competence with random success [i.e., he fools other stupid people some of the time, fails to fool other smart people some of the time.]
Furthermore, suppose that this stupid man is not exceptional in any way; however, he is not physically deformed or handicapped in any way.
What job should this man take in order to become reasonably wealthy? Or is it even possible? Is being stupid or unexceptional so damning that the man, without outside assistance, is generally a victim of his environment?
(There's a tie in to trading, since traders often don't really realize they are stupid until after the market gives them some kind of feedback.)
