Heather Royer, an economist at the University of California, Santa Barbara, thinks she has hit on a way. In partnership with a Fortune 500 company, she and her research partners ran an experiment that combined two interventions: One to get people to start going to the gym, and another to keep them there. For four weeks, the company paid its employees to work out, $10 per visit up to three times a week. After those four weeks, there were no more payments, but some workers were offered a “commitment contract”: They could set aside their own money that would be released to them only if they worked out over the next two months; otherwise, it would be given away to charity.
Even though those commitment contracts ended three months after the start of the study, the effects on workout frequency persisted for years: Three years after the study, the workers who had been offered the contracts remained 20 percent more likely to work out than those who had not been offered any incentives.
