Intuition, argues Gerd Gigerenzer, a director at the Max Planck Institute for Human Development, is less about suddenly "knowing" the right answer and more about instinctively understanding what information is unimportant and can thus be discarded. Gigerenzer, author of the book Gut Feelings: The Intelligence of the Unconscious, says that he is both intuitive and rational. "In my scientific work, I have hunches. I can’t explain always why I think a certain path is the right way, but I need to trust it and go ahead. I also have the ability to check these hunches and find out what they are about. That’s the science part. Now, in private life, I rely on instinct. For instance, when I first met my wife, I didn’t do computations. Nor did she."
