Q: In your new book you argue that people are probably even more selfish than we think.Me acordé de The Calzone de Seinfeld donde George se mete en problemas cuando da una propina justo cuando el pizzero se da vuelta e intenta recuperarla.
A: It's complex. The percentage of income people give to charities is on the order of 3%. Research my colleague John List is doing suggests that even when people do give, they don't give willingly except when someone's watching. He's looked at how people react when a person comes to the door asking for a charitable contribution. When he tells people in advance that there will be someone coming at a specific time, people either aren't there or don't open the door. Social pressure is behind a lot of contributions rather than altruism. If you and I were on TV and you'd just won the lottery and I asked you to give some to children in Haiti, you'd have a very hard time turning me down. But what if I sent you a letter in the mail making the exact same request?
Una propina no es caridad pero el principio tal vez no sea muy diferente (de paso, no hace mucho en un bar de aeropuerto me pasó la mismo... lección aprendida, resistí la tentación de meter la mano en el vaso de las propinas).
