The Hosts

Stephen J. Dubner

Stephen is the host of Freakonomics Radio, co-host of No Stupid Questions, and co-author of the Freakonomics books, which have won many awards and sold millions of copies around the world.

The eighth and last child of an upstate New York newspaperman, Stephen has been writing since he was a child. (His first published work appeared in Highlights magazine.) As an undergraduate at Appalachian State University, he started a rock band that was signed to Arista Records, which landed him in New York City. He ultimately quit playing music to earn an M.F.A. in writing at Columbia University, where he also taught in the English Department. He was an editor and writer at New York magazine and The New York Times before quitting to write books. He is happy he did so. In addition to the Freakonomics series, he is the author of Turbulent Souls (Choosing My Religion), Confessions of a Hero-Worshiper, and the children’s book The Boy With Two Belly Buttons. He lives in New York City.
