Tell Me Something I Don’t Know is a live game show and podcast hosted by Stephen J. Dubner, co-author of the Freakonomics books and host of Freakonomics Radio. He has always had a mission: to tell you the things you thought you knew but didn’t; and things you never thought you wanted to know, but do. Now, he has a new way of doing just that. TMSIDK is still journalism, still factual — but disguised in the most entertaining, unexpected, and occasionally ridiculous conversation you’re likely to hear.

Three celebrity panelists listen as contestants come on stage before a live audience and try to wow them 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. The panel — an eclectic mix of comedians, brainiacs, and other high achievers — poke and prod the contestants, and ultimately choose a winner.

Be a contestant!

We are looking for contestants to get up on stage and present their “I Don’t Know” — their IDK. It might be an unheralded technological breakthrough; a new line of important research; a cultural quirk; a historical wrinkle; or perhaps just a great, unasked question. All we ask is that it’s interesting (at least to you), worth knowing (at least a little bit), and — well, true (there is always a fact-checker on hand). Also: there will be prizes!

Selected presenters will be invited to our tapings, which will be turned into podcasts. To find out when we will be coming to your area, check out our schedule of events. Submit your IDK here.
