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

Some of the Hulk movies have been merely okay. I think the thing to do... there has to be some stab that makes it something we haven't seen before.

I think President Barack Obama has been an extraordinarily successful president, and that this period will record that with a bunch of exclamation points. But obviously not everybody thinks that.

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 interested in how the Internet spreads information.

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.

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.
