Gerd Gigerenzer is a pretty cool name. And this guy works at a pretty cool place, the Max Planck Institute for Human Development. Where, apparently, he leads a team who spend their days thinking about thinking. That's pretty darn cool. And in this book, Gigerenzer takes his work from the last 30 odd years and translates the heavy academic discourse into a lay person's guide to the theory of decision making based on hunches or instinct.
