A few year ago, students at Harvard University were asked to make a seemingly straightforward choice: which would they prefer, a job where they made $50,000 a year (option A) or one where they made $100,000 a year (option B)?
Seems like a no-brainer, right? Everyone should take option B. But there was one catch. In option A, the students would get paid twice as much as others, who would only get $25,000. In option B, they would get paid half as much as others, who would get $200,000. So option B would make the students more money overall, but they would be doing worse than others around them.
What did the majority of people choose?
Option A. They preferred to do better than others, even if it meant getting less for themselves. They chose the option that was worse in absolute terms but better in relative terms.
