via his 538 blog on the NY Times website. However, Nate was not a guest on Conan's talk show on TBS. Instead, they had a 50 minute long, non-commercial interrupted wide ranging chat about things like global warming, statistical probability, and the nature of capitalism. It's a fascinating chat and I've linked the full show below.
This interview is part of Conan's online-only "Serious Jibber Jabber" series of webcasts featuring guests that he chooses personally who he is interested in. Despite the silly title, it's all quite serious. The sidebar show started in September of this year, featuring historian Edmund Morris and a long conversation about Theodore Roosevelt. It seems almost as if Conan is angling for Charlie Rose's job in a few years as the format is similar but also features the same all black set with a table between them.
