Worries About Success Can Make You Successful

Economic View - NYTimes.com

In recent decades, behavioral economics has been the economics profession’s runaway growth area. Scholars in this field work largely at the intersection of economics and psychology, and much of their attention has focused on systematic biases in people’s judgments and decisions.

They point out, for example, that people are particularly inept at predicting how changes in their life circumstances will affect their happiness. Even when the changes are huge — positive or negative — most people adapt much more quickly and completely than they expected.

Such prediction errors, behavioral economists argue, often lead to faulty decisions. A celebrated example describes an assistant professor at a distinguished university who agonizes for years about whether he will be promoted. Ultimately, his department turns him down. As anticipated, he’s abjectly miserable — but only for a few months. The next year, he’s settled in a new position at a less selective university, and by all available measures is as happy as he’s ever been.

The ostensible lesson is that if this professor had been acquainted with the relevant evidence, he’d have known that it didn’t make sense to fret about his promotion in the first place —  that he would have been happier if he hadn’t. But that’s almost surely the wrong lesson, because failing to fret probably would have made him even less likely to get the promotion. And promotions often matter in ways that have little impact on day-to-day levels of happiness.

Paradoxically, our prediction errors often lead us to choices that are wisest in hindsight. In such cases, evolutionary biology often provides a clearer guide than cognitive psychology for thinking about why people behave as they do.

According to Charles Darwin, the motivational structures within the human brain were forged by natural selection over millions of years. In his framework, the brain has evolved not to make us happy, but to motivate actions that help push our DNA into the next round. Much of the time, in fact, the brain accomplishes that by making us unhappy. Anxiety, hunger, fatigue, loneliness, thirst, anger and fear spur action to meet the competitive challenges we face.

As the late economist Tibor Scitovsky said in “The Joyless Economy,” pleasure is an inherently fleeting emotion, one we experience while escaping from emotionally aversive states. In other words, pleasure is the carrot that provokes us to extricate ourselves from such states, but it almost always fades quickly.

The human brain was formed by relentless competition in the natural world, so it should be no surprise that we adapt quickly to changes in circumstances. Much of life, after all, is graded on the curve. Someone who remained permanently elated about her first promotion, for example, might find it hard to muster the drive to compete for her next one.
