The hour between dog and wolf : risk taking, gut feelings and the biology of boom and bust

A successful Wall Street trader turned Cambridge neuroscientist reveals the biology of boom and bust and how risk taking transforms our body chemistry, driving us to extremes of euphoria and risky behavior or stress and depression The laws of financial boom and bust, it turns out, have more than a little to do with male hormones. In a series of groundbreaking experiments, Dr. John Coates identified a feedback loop between testosterone and success that dramatically lowers the fear of risk in men, especially younger men—significantly, the fear of risk is not reduced in women. Similarly, intense failure leads to a rise in levels of cortisol, the antitestosterone hormone that lowers the appetite for risk across an entire spectrum of decisions. Coates had set out to prove what was already a strong intuition from his previous life: Before he became a world-class neuroscientist, Coates ran a derivatives desk in New York. As a successful trader on Wall Street, "the hour between dog and wolf" was the moment traders transformed-they would become revved up, exuberant risk takers, when flying high, or tentative, risk-averse creatures, when cowering from their losses. Coates understood instinctively that these dispositions were driven by body chemistry—and then he proved it. The Hour Between Dog and Wolf expands on Coates's own research to offer lessons from the entire exploding new field—the biology of risk. He brings his research to life by telling a story of fictional traders who get caught up in a bubble and then a crash. As these traders place their bets and live with the results, Coates looks inside bodies to describe the physiology driving them into irrational exuberance and then pessimism. Risk concentrates the mind—and the body—like nothing else, altering our physiology in ways that have profound and lasting effects. What's more, biology shifts investors' risk preferences across the business cycle and can precipitate great change in the marketplace. Though Coates's research concentrates on traders, his conclusions shed light on all types of high-pressure decision making-from the sports field to the battlefield. The Hour Between Dog and Wolf leaves us with a powerful recognition: To handle risk in a "highly evolved" way isn't a matter of mind over body; it's a matter of mind and body working together. We all have it in us to be transformed from dog into wolf; the only question is whether we can understand the causes and the consequences. __A successful Wall Street trader turned Cambridge neuroscientist reveals the biology of boom and bust and how risk taking transforms our body chemistry, driving us to extremes of euphoria and risky behavior or stress and depression__ The laws of financial boom and bust, it turns out, have more than a little to do with male hormones.

The laws of financial boom and bust, it turns out, have a lot to do with male hormones. In a series of startling experiments, Canadian scientist Dr. John Coates identified a feedback loop between testosterone and success that dramatically lowers the fear of risk in men, especially young men; he has vividly dubbed the moment when traders transform into exuberant high flyers "the hour between dog and wolf."

A successful Wall Street trader turned neuroscientist reveals how risk taking and stress transform our body chemistryBefore he became a world-class scientist, John Coates ran a derivatives trading desk in New York City. He used the expression “the hour between dog and wolf” to refer to the moment of Jekyll-and-Hyde transformation traders passed through when under pressure. They became cocky and irrationally risk-seeking when on a winning streak, tentative and risk-averse when cowering from losses. In a series of groundbreaking experiments, Coates identified a feedback loop between testosterone and success—one that can cloud men's judgment in high-pressure decision-making. Coates demonstrates how our bodies produce the fabled gut feelings we so often rely on, how stress in the workplace can impair our judgment and even damage our health, and how sports science can help us toughen our bodies against the ravages of stress. Revealing the biology behind bubbles and crashes, The Hour Between Dog and Wolf sheds new and surprising light on issues that affect us all. A Wall Street trader-turned-neuroscientist reveals the biology of boom-and-bust cycles to explain the impact of risk taking on body chemistry, citing the relationship between testosterone, decision making, and emotional health.
