The use of feedback loops does not end when a session is over. Winners often make notes about the way people played and the best strategy to use against them. For example, someone might normally be tight and moderately aggressive but get much wilder when he is losing or drinking heavily. The next time they played, the notetaker would quickly learn how many drinks his opponent has had and whether he was winning or losing. He would then make appropriate adjustments.

Biases are so common and influential that scientific methods use tight controls to minimize their effects. For example, the FDA won’t approve a drug unless it’s tested in double-blind studies. Neither the patient nor the researcher knows who received a drug or a placebo.
