““This has the added negative effect of giving them the illusion of confidence. It is a hard lesson to accept, but the success of many people is due to luck, not knowledge. If a thousand people try a thousand different methods and one of them hits the jackpot, it is an illusion to think the winner necessarily had more knowledge or skill than the losers. If two psychics pick opposite winners in an athletic contest, one of them may appear to have more knowledge that the other, but the appearance is an illusion.””
