In 1989 the psychologist Dietrich Dörner published Die Logik des Mißlingens, the logic of failure. He studied how people act in complex situations, using computer simulations. In one of them, participants managed Tanaland, an imaginary region in Africa. In another they ran Lohhausen, a simulated small town. A chapter on dealing with goals discusses global goals and what Dörner calls Reparaturdienstverhalten, repair-service behavior. Dörner’s first step for acting in complex situations is to become clear about the goal. Many people, he found, already fail at this first step.
