The document discusses Malcolm Gladwell's book "Blink" which examines how quick, unconscious decisions called "thin-slicing" can be as accurate as slower, deliberate decisions. It describes several studies including art experts correctly identifying fakes within seconds, a tennis coach predicting double faults, and gamblers unconsciously favoring better decks of cards before consciously realizing. While quick decisions can be accurate, biases from implicit associations can also influence them. The document argues we can improve quick decisions through experience, understanding our biases, and using priming to temporarily change associations.
