How We Decide

Since Plato, philosophers have described the decision making process as either rational or emotional: we carefully deliberate or we "blink" and go with our gut. But as scientists break open the mind’s black box with the latest tools of neuroscience, they’re discovering that this is not how the mind works.

Our best decisions are a finely tuned blend of both feeling and reason—and the precise mix depends on the situation. The trick is to determine when to lean on which part of the brain, and to do this, we need to think harder (and smarter) about how we think.

Jonah Lehrer arms us with the tools we need, drawing on cutting-edge research as well as the real-world experiences of a wide range of "deciders"—from airplane pilots and hedge fund investors to serial killers and poker players.

Lehrer shows how people are taking advantage of the new science to make better television shows, win more football games, and improve military intelligence. His goal is to answer two questions: How does the human mind make decisions? And how can we make those decisions better?

Jonah Lehrer is editor at large for Seed magazine and the author of Proust Was a Neuroscientist. A graduate of Columbia University and a Rhodes scholar, Lehrer has written for The New Yorker, the Washington Post, and the Boston Globe. He edits the Mind Matters blog for Scientific American and writes his own highly regarded blog, The Frontal Cortex.
