““People were given a choice between receiving a coffee mug or some money, and asked how much money they’d need to choose money over mug. The answer was about $3.50. But when given the mug to keep, then asked how much cash they’d want to give it back, the answer averaged $7.12. Apparently the fact that it becomes my mug endows it with some special quality that makes it more than twice as valuable as a mug off the shelf. The idea of giving up our stuff makes for more misery units than all the happiness they brought us.””
