We're back! Here's a preview of our second season which begins February 19th. Over the next 10 weeks you'll hear all sorts of fascinating things you didn't know, as our contestants try to wow captains of industry, heads of institutions and other professional smart people, plus great comedians like Aasif Mandvi, Lizz Winstead, John Fugelsang, Faith Salie, Aman Ali, Tami Sagher, Eugene Mirman, Hari Kondabolu, and Maeve Higgins.

Season 2 Preview

Journalism wrapped in a game-show package. Host Stephen J. Dubner (of “Freakonomics Radio”) and a celebrity co-host invite guests on stage in front of a live audience to tell us something we don’t know. The co-hosts — a mix of leaders in science, academia, sports, media, and comedy — grill the guests, and by the end we’ve all gotten a bit smarter. Each episode has a new topic, a new co-host, and new guests. There’s also a real-time human fact-checker to keep everyone honest. Think of the most crackling dinner-party conversation you’ve ever heard. Produced in association with Stitcher.
