Chapter One


Thaler's Apples

The behavioral revolution in economics began in 1981 when Richard Thaler published a seven-page letter in a somewhat obscure economics journal. Richard is now a stocky sixty-three-year-old with unruly gray hair who looks more like a bartender than one of the world's leading economists. But back then, a thirty-five-year-old Richard posed a pretty simple choice about apples.

Which would you prefer:

(A) One apple in one year or

(B) Two apples in one year plus one day?

This is a strange hypothetical-why would you have to wait a year to receive an apple? But choosing is not very difficult; most people would choose to wait an extra day to double the size of their gift.

Thaler went on, however, to pose a second apple choice.

Which would you prefer:

(C) One apple today or

(D) Two apples tomorrow?

What's interesting is that many people give a different, seemingly inconsistent answer to this second question. Many of the same people who are patient when asked to consider this choice a year in advance turn around and become impatient when the choice has immediate consequences-they prefer C over D. When it comes to apples, Adam and Eve aren't alone in being impatient when presented with an immediate temptation.

The inconsistency in these answers puzzled Thaler. Richard has an incredible eye for anomalies. While many economists ignore or paper over deviations from rationality, Thaler is drawn to them. He's made a career of trying to understand them, and he even writes down algebraic formulas to capture their essence. Why would he mow his own lawn to save $15 but wouldn't be willing to cut his neighbor's lawn even for $25? Why would his decision about whether to drive through a snowstorm to see a basketball game turn on whether he paid for or was given the ticket? Thaler's obsession with the failure of traditional economics may end up earning him the Nobel Prize. By integrating psychology into economic theory, Thaler and a cadre of other behavioral economists have remade the landscape of economic thinking.

Today the defenders of the faith in economic rationality are still dominant in economic departments across the country, but they are increasingly acknowledging the power of behavioral predictions. While economists have traditionally focused on information and incentives as the core levers of human behavior, Thaler often thinks about what he calls "choice architecture." Simply and slightly reframing the context in which decisions are made can have big effects on people's behavior and happiness. Thaler is even willing to reengineer the rules of golf.

Cade Massey, a Yale business professor, played golf with Thaler soon after Thaler had taken up the game. "Dick suggested that we play with a different scoring rule," he recalls. "You'd get one point for every hole that you parred and nothing for every other hole, regardless of how badly you did. The winner was the person with the most points. This simple rule change really improved my enjoyment. The problem with traditional scoring for a golfer like me is that I could screw up a decent round with a bad score on a single hole." Richard's method allowed Cade to focus more on his successes than his failures. The story also shows how Thaler is constantly trying to use what he knows about how our minds work to increase people's happiness.

The golf purists out there will resist the idea that a scoring change could make golf more enjoyable. Or they might insist that it wouldn't be golf anymore. But Thaler has gone after much larger fish. His impulse to tinker with the rules of the game led him to champion the Save More Tomorrow program. Thaler saw that lots of people were having trouble taking advantage of their companies' 401(k) plans-even when their employers were willing to match their contributions dollar for dollar. It just hurts too much to see your current paycheck go down. But Save More Tomorrow lets people sign up for participation without their current or future paychecks ever declining. Savings contributions are made only out of a portion of future pay increases. These contributors usually reach full participation within four or five years. Over the course of a working life, this is a fairly small delay. But Richard's small change has shown big results. Employees who would never have otherwise invested in a 401(k) plan have been saving for retirement at nearly the same rate as those employees who chose to invest in their 401(k) plans from the start.

The seeds of this idea were planted back with those simple questions about whether you'd be willing to wait an extra day for an extra apple. Thaler's curiosity about the inconsistent answers to the two questions helped spark a revolution in economic thinking. Why were people more impatient when the proffered gifts were closer at hand? Both hypotheticals ask us if we're willing to wait an extra day to double the size of our gift. The only difference is the time perspective.

Now, one way out of this conundrum is to focus on trust. We're taught the old maxim that "a bird in the hand is worth two in the bush," because promised future paydays don't always materialize. The people who prefer an apple today may not trust that they'll actually be given two apples if they wait till tomorrow (whereas they don't think there's much of a difference in the likelihood of being given one or two apples if they have to wait a year).

But Thaler thought there was something else going on.

What was revolutionary about his apple example is that it illustrated the plausibility of what behavioral economists call "time- inconsistent" preferences. Richard was centrally interested in the people who chose both B and C. These people, who preferred two apples in the future but one apple today, flipped their preferences as the delivery date got closer.

Indeed, we can imagine anchoring the dates somewhere in the distant future (Would you prefer an apple on April 4 or two apples on April 5?) and then revisiting the question on a daily basis. Initially, when April is far away, people would choose to double their gift by taking the April 5 option. But because of a time-inconsistent preference, there would come a day where suddenly people would shift to the option of one apple on April 4. This flip in preference is the key to the behavioral revolution in economics.

If we change the hypothetical from apples to crack, it's easy to understand this kind of time inconsistency. A drug-deprived addict may prefer an immediate fix to a double dose tomorrow. When we hear about someone like Alex choosing the immediate small pleasure of induced sneezing to the larger future pleasure of clear lungs, we might be quick to think of him as having an addictive personality or some kind of OCD (obsessive-compulsive disorder). But Thaler's apple example shows that you don't need psychopharmacological dependence to exhibit irrational impatience. Even with regard to something as prosaic and healthful as an apple, many people in the world become impatient as their time horizon shrinks.

In at least some aspects of their lives, many people are addicted to now. We are seduced by the immediacy of gratification. The apple choice is replayed repeatedly throughout our lives. My kids put off cleaning their rooms and then waste huge amounts of time looking for a misplaced sweater or birthday invitation. A friend of our family again and again put off buying life insurance and then tragically left his family unprotected. The marginal convenience of delaying a mammogram or other mildly unpleasant task blinds us to the exponential pain just around the bend. I turned fifty almost a year ago, and I still haven't had a colonoscopy.

If asked in late January, most of us would say we would rather spend eight hours working on our taxes on April 1...
