The casino floor is a monument to human certainty. The man at the craps table throws the dice with a ritualistic flick, convinced his technique influences the outcome. The woman at the roulette wheel records reds and blacks on a napkin, certain she has spotted a pattern that will let her beat the house. They are not stupid people. They are rational people doing something deeply irrational: they are trying to control what cannot be controlled. And the house, which understands their brains far better than they do, is more than happy to let them try. This is the gambler’s trap, and it is not confined to Las Vegas.
