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