blink
Malcolm Gladwell's new book Blink
We live in a society dedicated to the idea that we're always better off gathering as much information and spending as much time as possible in deliberation. As children, this lesson is drummed into us again and again: haste makes waste, look before you leap, stop and think. But I don't think this is true. There are lots of situations--particularly at times of high pressure and stress--when haste does not make waste, when our snap judgments and first impressions offer a much better means of making sense of the world.
One of the stories I tell in "Blink" is about the Emergency Room doctors at Cook County Hospital in Chicago. That's the big public hospital in Chicago, and a few years ago they changed the way they diagnosed heart attacks. They instructed their doctors to gather less information on their patients: they encouraged them to zero in on just a few critical pieces of information about patients suffering from chest pain--like blood pressure and the ECG--while ignoring everything else, like the patient's age and weight and medical history. And what happened? Cook County is now one of the best places in the United States at diagnosing chest pain.
Not surprisingly, it was really hard to convince the physicians at Cook County to go along with the plan, because, like all of us, they were committed to the idea that more information is always better. But I describe lots of cases in "Blink" where that simply isn't true. There's a wonderful phrase in psychology--"the power of thin slicing"--which says that as human beings we are capable of making sense of situations based on the thinnest slice of experience. I have an entire chapter in "Blink" on how unbelievable powerful our thin-slicing skills are. I have to say that I still find some of the examples in that chapter hard to believe.
