My role in the government was not to think about narratives and consistency with narratives, but think of the human consequences of rules.

Rumors are nearly as old as human history, but with the rise of the Internet, they have become ubiquitous. In fact we are now awash in them. False rumors are especially troublesome; they impose real damage on individuals and institutions, and they often resist correction. They can threaten careers, policies, public officials, and sometimes even democracy itself.

Sometimes, the word 'voluntary' is a little complicated.

I would reject the distinction between a Keynesian moment and a behavioral moment.

Most problems are best solved privately, not through government. There's a problem of discourtesy in the world, which is best handled through social norms, which are indispensable. But you wouldn't want the government to be mandating courtesy.

Great works - and I think Star Wars is a great work - are easily susceptible to multiple plausible interpretations. Some of them are pretty nutty, but the idea that we should see it as profoundly feminist, or as a deeply Christian tale, or as a Freudian exercise... I think all of those have some truth.

I'm also a big Bob Dylan fan. The songs on The Freewheelin' Bob Dylan - which is one of his best early albums - they grow out of some of his difficulties with Suze Rotolo, and "Hard Rain," people say it had to do with the Cuban missile crisis - probably not. He denied it. I believe him, but it certainly had to do with the time.
