Do Commitment Contracts Really Work?

Sometimes people don't need to make commitment contracts. They don't have a problem with following through. Sometimes you're going to want to make commitments over inputs more than on results. I have a friend who's a habitual overeater who said she would just be too scared to lose money on a commitment contract. She could have made a commitment to get on the scale once a day. You could make a commitment to study a certain number of hours even if you can't make an A on a test.
