Why is the human need to be in control relevant to a discussion of random patterns? Because if events are random, we are not in control, and if we are in control of events, they are not random, there is therefore a fundamental clash between our need to feel we are in control and our ability to recognize randomness. That clash is one of the principal reasons we misinterpret random events. In fact, inducing people to mistake luck for skills, or pointless actions for control, is one of the easiest enterprises a research psychologist can engage in ask people to control flashing lights by pressing a dummy button, and they will believe they are succeeding even though the lights are flashing at random. Show people a circle of lights that flash at random and tell them that by concentrating they can cause the flashing to move in clockwise direction, and they will astonish themselves with their ability to make it happen.
