 A lot of times the healthy choice requires a lot of willpower, so you have to resist all the bad options in order to choose the healthy option. And so making the healthy choice the easy choice reduces the amount of willpower that people have to spend on their eating and their exercise decisions. My dissertation research was when I first got interested in incentives. What we did was we incentivized first-year college students here at UVM to go to the campus fitness center and when they went to the fitness center they and they met goals of attendance they would get paid for doing that. And students who we paid went to the fitness center more often than students who we didn't pay. And so yeah it worked to incentivize this behavior. And in my class that I teach for juniors and seniors we do a whole section on behavioral economics. I definitely my research permeates my teaching and then back the other way.
