If you wanna get really stupid in the fastest and easiest way possible, make sure to only surround yourself with like-minded people. All the others are evil and ignorant anyway…

Watch Cass Sunstein debate his book Infotopia: How Many Minds Produce Knowledge with Tyler Cowen and Robin Hanson from George Mason University at the AEI-Brookings Joint Center:

If you enjoyed this talk, also watch Professor Sunstein debate Extremism or read his great essay on the topic:
