Why Incentives Matter

I came across this wonderful parable from Matthew May's blog:

An old woman lived alone on a street where boys played noisily every afternoon. One day, the din became too much, and she called the boys into her house. She told them she liked to listen to them play, but her hearing was failing and she could no longer hear their games. She asked them to come around each day and play noisily in front of her house. If they did, she would give them each a quarter. The youngsters raced back the following day, and they made a tremendous racket playing happily in front of the house. The old woman paid and asked them to return the next day. Again they played and made noise, and again she paid them for it. But this time she gave each boy only 20 cents, explaining that she was running out of money. On the following day, they got only 15 cents each. Furthermore, the old woman told them she would have to reduce the fee to a nickel on the fourth day. The boys then became angry and said they would not be back. It was not worth the effort, they said, to play for only a nickel a day.

This parable reminds me of what Charlie Munger once said about incentives:

......Another thing, perverse incentives. You do not want to be in a perverse incentive system that’s causing you to behave more and more foolishly or worse and worse - incentives are too powerful a control over human cognition or human behavior. If you’re in one, I don’t have a solution for you. You’ll have to figure it out for yourself, but it’s a significant problem.

  1. Very insightful! We are so often oblivious to the control incentives have on us, even when they make us behave more and more foolishly, as Munger says. I'm going to start paying more attention.
