Under conditions of true complexity–where the knowledge required exceeds that of any individual and unpredictability reigns–efforts to dictate every step from the center will fail. People need room to act and adapt. Yet they cannot succeed as isolated individuals, either–that is anarchy. Instead, they require a seemingly contradictory mix of freedom and expectation–expectation to coordinate, for example, and also to measure progress toward common goals.
