The Power of Experiments

The income effect that is the fact that with more income people become more lazy is never really found. In some circumstances you find the opposite. But when you give people money they work more because that open the space where they are more focused and less stressed. They can either work more hour or be more productive during the hours where they work. What's interesting in this story is that one experiment doesn't change anybody's mind it really has to be the accumulation of experiments to change something so powerful.
