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

I dealt with people with diverse political views. If you find people who are your political opponents, and talk to them for an hour, chances are you're going to like them, and they're not full of hate.

Those who believe in climate change, as I do, I think it's also fair to say that they are more receptive to confirming evidence than disconfirming evidence. They happen to be right, but their motivations are in play also.

Groups become more extreme and entrenched in their beliefs and polarized from others when members only exchange information that reinforces their views and filter out all else or never learn of alternatives. Thus they narrow their options, and magnify each other's prejudices and misconceptions. This trend leads to blind spots in decision making and to extreme behavior, even terrorism.

I love The Matrix, especially the first one.

I started to read as obsessively about Star Wars as I once did about Kant - and still do about behavioral economics and behavioral psychology.

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.
