OLLI-CO Book Discussion Group resumes their regular schedule in October, with a non fiction selection:
How We Decide by Jonah Lehrer
Our politicians and voters have split into two, irreconcilable camps.Each group is certain that their shared view of reality is right and logical (based on facts) and that the other group’s is irrational and dangerous. These opposing dogmatic views stop politicans from working together for the common good at a time of national crisis. How have we come to this? What can we do about it?
In his New York Times Bestseller “How We Decide”, Jonah Lehrer describes the how our brains decide what to believe and what to do. That superficially bad new is that few of these beliefs or decisions are rational. The really bad news is that the beliefs we’ve convinced ourselves to be the most rational are the most likely to be at odds with reality, and our most rational decisions usually leave us less satisfied in the long run. When the brain makes its best decisions, as measured by numerous controlled experiments and long term results, those decisions involve our emotions, pleasure and pain centers, centers of empathy and a thousand other subtle things which the brain has evolved to incorporate in its decision making process. Our logical explanations of our beliefs are, as Jonah Lehrer puts it, more that of lawyers picking and chosing things that, post facto, justify beliefs and decisions produced for other reasons. Once we make decisions, our rational mind proceeds to whip other brain centers into shape to ignore data which contradicts its decisions and to enhance and change memories to support those decisions. In other words, it acts like a General, Politician, Pope or corporate CEO who sets out to eliminate dissension in the ranks after he’s chosen a course of action. What’s the payoff for doing this…. when we reaffirm our decisions, the brain releases dopamine which produces a sense of pleasure and well being.
A heathy brain’s processes, of which reason is merely one of the last to evolve and one of the weakest, enable people to be creative, playful, empathize with others and anticipate their reactions. Brain’s of psychopaths lack empathy for the feeling of others. Psychopaths and sociopaths are actually very rational like Dr. Spock from Star Trek. They are without natural feelings of fear or of empathy for others because certain, tiny, regions of the brain are damaged. The damage can result from physical causes or from emotional traumas, particularly abuse or isolation in early childhood. For those who are convinced that without Christianity we would lack ethics and morals, this might not be a comfortable book. The book describes research which conclusively demonstrates that healthy brains have built in ethics and morals; which the 10 Commandments and the New Testament merely codify. Even healthy chimpanzees exhibit some ethical behaviors!
This interesting book is packed with relevant stories about airline pilots and football quarterbacks (and the rational, but useless tests the NFL employs to predict their performance) and a few pertinent metaphors. Jonah Lehrer worked as a technician in a neuroscience lab, but he is first and foremost a top-notch writer who knows how to popularize difficult scientific topics. Chapter headings include: The Quarterback in the Pocket, The Predictions of Dopamine, Choking on Thought, The Moral Mind, and The Brain is an Argument.
