Switch: How to Change Things When Change Is Hard

by Chip Heath

The conventional wisdom in psychology, in fact, is that the brain has two independent systems at work at all times. First, there’s what we called the emotional side. It’s the part of you that is instinctive, that feels pain and pleasure. Second, there’s the rational side, also known as the reflective or conscious system. It’s the part of you that deliberates and analyzes and looks into the future. In the past few decades, psychologists have learned a lot about these two systems, but of course mankind has always been aware of the tension. Plato said that in our heads we have a rational charioteer who has to rein in an unruly horse that “barely yields to horsewhip and goad combined.” Freud wrote about the selfish id and the conscientious superego (and also about the ego, which mediates between them). More recently, behavioral economists dubbed the two systems the Planner and the Doer. But, to us, the duo’s tension is captured best by an analogy used by University of Virginia psychologist Jonathan Haidt in his wonderful book The Happiness Hypothesis. Haidt says that our emotional side is an Elephant and our rational side is its Rider. Perched atop the Elephant, the Rider holds the reins and seems to be the leader. But the Rider’s control is precarious because the Rider is so small relative to the Elephant. Anytime the six-ton Elephant and the Rider disagree about which direction to go, the Rider is going to lose. He’s completely overmatched.
