I recently came across a web site where VW is trying to do exactly the same thing. They are encouraging people to use game theory to make the world a better place. One of my favorites is the place in Sweden where they turned a speed trap into a game. Normally, those cameras that take pictures of people who are speeding and send them a speeding ticket are a real nuisance. In this case they made it into a lottery. Just as before, if you speed, the camera takes you picture and sends you a ticket with a hefty fine that you need to pay. However, if you don't speed, the camera also takes your picture. Its just that in this case it enters you into a lottery. If you are chosen, you get a share of the money from the people who paid the fines. Apparently, speeding at the intersection in question was reduced significantly.
They also turned a bottle recycling bin into a game
Even a trash bin can be made fun
(notice that all these videos take place in Sweden)
I suppose even our FitBits are making exercise more fun. Do you think you could make it fun for people to do things that help the world and each other?
