Listen to No Stupid Questions on Spotify. Stephen Dubner (co-author of the Freakonomics book series) and research psychologist Angela Duckworth (author of Grit) really like to ask people questions, and came to believe there’s no such thing as a stupid one. So they made a podcast where they can ask each other as many “stupid questions” as they want. New episodes each week. No Stupid Questions is a production of the Freakonomics Radio Network.
