The real world laws are puzzlingly different from those of the logical world, and more thinking or more information is not always better, challenges Gerd Gigerenzer in ‘Gut Feelings’ ( http://www.penguin.com/ ). Intuition can solve many problems, he says. “Intelligence is frequently at work without conscious thought.”
Gut feeling is judgment that appears quickly in consciousness, whose underlying reasons we are not fully aware of, and is strong enough to act upon, explains the author. Gut feelings take advantage of the evolved capacities of the brain and are based on rules of thumb that enable us to act fast and with astounding accuracy, he says.
