There is a very interesting article at the Atlantic from David Just and Brian Wansink from the Cornell Center for Behavioral Economics in Child Nutrition Programs. They discuss their work on improving healthy eating in school cafeterias using the subtle wizardry of behavioral economics. There have been some impressive results:
One school in upstate New York was able to increase consumption of salads by close to 300 percent by simply moving their salad bar six feet from the wall and placing it near a natural bottleneck in the check-out line. Another school increased fruit sales by 105 percent by moving the apples and oranges from stainless steel bins into a well-lit and attractive basket.
It is encouraging to see behavioral economics being put into creative use like this. The authors argue that “It is difficult to teach a high school student how to make healthy choices in the real world if only escarole and tofu on are on the school lunch menu”. But is this teaching them to choose better or tricking them into choosing better? After all, if behavior is so amenable to subtle tricks like this then what hope can there be that any behavioral changes will actually last? I can’t tell if articles like this should make us more or less hopeful. Yes, the good scientists here are making a difference, but are we really so impressionable?
