Tonight, at dinner, a friend asked, "Don't you get tired of people asking you for favors?" I laughed and answered, "No, I always recognize the Benjamin Franklin Effect."
The friend asked me to explain. The Benjamin Franklin Effect: asking other people for favors is a way of getting them to like you.
That's the centuries-old psychological phenomenon proposed by Benjamin Franklin, who wrote this maxim in his autobiography: "He that has once done you a kindness will be more ready to do you another, than he whom you yourself have obliged."
