Blink: The Power of Thinking Without Thi - By Gladwell, Malcolm Page 0,3

were high, where things were moving quickly, and where the participants had to make sense of a lot of new and confusing information in a very short time. What does the Iowa experiment tell us? That in those moments, our brain uses two very different strategies to make sense of the situation. The first is the one we’re most familiar with. It’s the conscious strategy. We think about what we’ve learned, and eventually we come up with an answer. This strategy is logical and definitive. But it takes us eighty cards to get there. It’s slow, and it needs a lot of information. There’s a second strategy, though. It operates a lot more quickly. It starts to kick in after ten cards, and it’s really smart, because it picks up the problem with the red decks almost immediately. It has the drawback, however, that it operates-at least at first-entirely below the surface of consciousness. It sends its messages through weirdly indirect channels, such as the sweat glands in the palms of our hands. It’s a system in which our brain reaches conclusions without immediately telling us that it’s reaching conclusions.

The second strategy was the path taken by Evelyn Harrison and Thomas Hoving and the Greek scholars. They didn’t weigh every conceivable strand of evidence. They considered only what could be gathered in a glance. Their thinking was what the cognitive psychologist Gerd Gigerenzer likes to call “fast and frugal.” They simply took a look at that statue and some part of their brain did a series of instant calculations, and before any kind of conscious thought took place, they felt something, just like the sudden prickling of sweat on the palms of the gamblers. For Thomas Hoving, it was the completely inappropriate word “fresh” that suddenly popped into his head. In the case of Angelos Delivorrias, it was a wave of “intuitive repulsion.” For Georgios Dontas, it was the feeling that there was a glass between him and the work. Did they know why they knew? Not at all. But they knew.

2. The Internal Computer The part of our brain that leaps to conclusions like this is called the adaptive unconscious, and the study of this kind of decision making is one of the most important new fields in psychology. The adaptive unconscious is not to be confused with the unconscious described by Sigmund Freud, which was a dark and murky place filled with desires and memories and fantasies that were too disturbing for us to think about consciously. This new

notion of the adaptive unconscious is thought of, instead, as a kind of giant computer that quickly and quietly processes a lot of the data we need in order to keep functioning as human beings. When you walk out into the street and suddenly realize that a truck is bearing down on you, do you have time to think through all your options? Of course not. The only way that human beings could ever have survived as a species for as long as we have is that we’ve developed another kind of decision-making apparatus that’s capable of making very quick judgments based on very little information. As the psychologist Timothy D. Wilson writes in his book Strangers to Ourselves: “The mind operates most efficiently by relegating a good deal of high-level, sophisticated thinking to the unconscious, just as a modern jetliner is able to fly on automatic pilot with little or no input from the human, ‘conscious’ pilot. The adaptive unconscious does an excellent job of sizing up the world, warning people of danger, setting goals, and initiating action in a sophisticated and efficient manner.” processes a lot of the data we need in order to keep functioning as human beings.
