Poker and Rational Thinking: Why Intelligence Isn't Everything

The ability to think rationally is weakly correlated with intelligence. A common cognitive error is ignoring alternative assumptions. Richard Dawkins describes natural selection as choosing the best available option at the time. The brain often uses simple, quick, and economical thinking mechanisms to conserve energy. Poker players often face the internal conflict between playing correctly and making quick decisions. The problem is not with the decision-making mechanisms themselves, but with their rationality. A common cognitive error is the tendency to adjust facts to fit one's beliefs.
