The third example is a behavior change example and maybe not one of the ones you might expect. This example has to do with speeding so how do the police get people not to speed? Well the traditional way they do it is by putting a guy like this with a radar gun and sitting there and watching and if you're caught speeding You get a ticket and you have to pay a fine. Well, that works okay. But it's incredibly imperfect. People only will slow down if they think there's going to be a cop there. And there's no way there's going to be a cop on every corner at every time. So what some police departments have done is put in. Monitors put in devices that show you how fast you're going as you're going by. And that has actually had some effect even when they aren't tied to the police department. They're just telling you your speed. That provides some feedback, seeing real time feedback causes a behavior loop, it causes people to react. So even though you know how fast you're going, or you could know how fast you're going just by looking at the speedometer, seeing a sign up in front of you telling you your speed in real time, Tends to have an effect and actually causes people often to slow down. Now potentially though, we could go further than this. Volkswagen had a contest called The Fun Theory. It was a marketing program where they encouraged people to submit great ideas for using games and fun to solve real-world problems.
