Then one day, my cofounder, aviln, came across a study of students in Chicago led by the behavioral economist, steevn Levitt, where they paid sutntdes who improved on their test scores. He started telling me about some of the things they tested for and the interesting findings they had. For instance, they found that incentivizing students for inputs, like erofft, worked a lot better than incentivizing for ottuups, like test scores. They found that for yogeunr students, you could win them over with a trophy but for older students, you really needed cash.
