At the risk of starting starting a discussion that will be wrecked by political wrestling, I'm always hopeful when I hear about governments applying what we learn from science to policy.

In this case they are applying it to meta-policy, rather than policy: how to get people to go along with their policy.

Here is another excerpt:

"Just understanding that human beings don't make perfect decisions does not make the case for government by any stretch of the imagination," Glaeser says. "After all, governments are made up of people, too. They are subject to the same foibles and weakness as the rest of us."
