Social herding presses us to think that everything is OK (or not OK) because everyone else is saying so. The inside view presses us to ignore the lessons of other times and other places, believing that our company, our nation, our new venture, or our era is different. It is important to push back against these biases. You can do this by paying attention to real-world data that refutes the echo-chamber chanting of the crowd—and by learning the lessons taught by history and by other people in other places.
