Freakonomics Radio Live! is live journalism wrapped in a game-show package where we play a game called "Tell Me Something I Don't Know." Hosted by Stephen J. Dubner, it has the same kind of factual, inquisitive journalism that has been a hallmark of Freakonomics Radio, but it’s disguised in the most entertaining, unexpected, and occasionally ridiculous conversation you’re likely to hear.

Contestants come on stage before a live audience and try to wow Stephen and his guest co-host with a fascinating fact — a historical wrinkle, a new line of research — anything, really, as long as it’s interesting, useful and true (or at least true-ish). There’s a real-time human fact-checker on hand to filter out the bull. And the audience gets to vote for a winner!
