Experts are often right, but they are also often wrong. We need credentialed authorities because their deep knowledge helps us make sense of complexity. But when it comes to prediction, seek out foxes, that is, the generalists and synthesizers, because their broad perspective and adaptability make them better at spotting large patterns and recognizing new realities. In the end, the wisest guide is not the hedgehog who knows one big thing but the fox who pays attention to everything.
