Excerpt from Jim Collin's book, From Good to Great

Princeton professor Marvin Bressler pointed out the power of the hedgehog during one of our long conversations: "You want to know what separates those who make the biggest impact from all the others who are just as smart? They're hedgehogs."

Freud and the unconscious, Darwin and natural selection, Marx and class struggle, Einstein and relativity, Adam Smith and division of labor-they were all hedgehogs. They took a complex world and simplified it. "Those who leave the biggest footprints," said Bressler, "have thousands calling after them, 'Good idea, but you went too far!' "

To be clear, hedgehogs are not stupid. Quite the contrary. They understand that the essence of profound insight is simplicity. What could be more simple than e = mc2? What could be simpler than the idea of the unconscious, organized into an id, ego, and superego?

What could be more elegant than Adam Smith's pin factory and "invisible hand"? No, the hedgehogs aren't simpletons; they have a piercing insight that allows them to see through complexity and discern underlying patterns. Hedgehogs see what is essential, and ignore the rest.
