Prefrontal cortex in action

Q: HOW WE DECIDE draws from the latest research in neuroscience yet also analyzes some crucial moments in the lives of a variety of "deciders," from the football star Tom Brady to a soap opera director. Why did you take this approach?

A: Herbert Simon, the Nobel Prize-winning psychologist, famously compared our mind to a pair of scissors. One blade, he said, represented the brain. The other blade was the specific environment in which our brain was operating. If you want to understand the function of scissors, Simon said, then you have to look at both blades simultaneously. What I wanted to do in HOW WE DECIDE was venture out of the lab and into the real world so that I could see the scissors at work. I discuss some ingenious experiments in this book, but let's face it: the science lab is a startlingly artificial place. And so, wherever possible, I tried to explore these scientific theories in the context of everyday life. Instead of just writing about hyperbolic discounting and the feebleness of the prefrontal cortex, I spent time with a debt counselor in the Bronx. When I became interested in the anatomy of insight⎯where do our good ideas come from?⎯I interviewed a pilot whose epiphany in the cockpit saved hundreds of lives. That's when you really begin to appreciate the power of this new science--when you can use its ideas to explain all sorts of important phenomena, such as the risky behavior of teenagers, the amorality of psychopaths, and the tendency of some athletes to choke under pressure.
