Join host Stephen J. Dubner of “Freakonomics Radio†and three celebrity panelists as they invite contestants on stage to tell us something we don’t know. It could be a fascinating fact, a historical wrinkle, a new line of research — anything, really, 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 — will poke and prod the contestants and ultimately choose a winner. Like the “Freakonomics†podcast and books, “Tell Me Something I Don’t Know†is still journalism, still factual — but disguised in the most entertaining, unexpected and occasionally ridiculous conversation you’re likely to hear. Produced in partnership with The New York Times.
