People I (Mostly) Admire

People I (Mostly) Admire is hosted by Steven Levitt, the iconoclastic University of Chicago economist and co-author of the Freakonomics book series, who tracks down other high achievers and asks questions that only he would think to ask. Guests include all-time Jeopardy! champion Ken Jennings, Harvard psychologist and linguist Steven Pinker, and WNBA champion Sue Bird. The weekly show features conversations with a wide array of guests — from actresses to athletes, authors to inventors.

“The perfect guest for me is someone who’s not only wildly intelligent, but also a little bit off the rails,” Levitt says. “Someone who thinks differently and who doesn’t care at all how the world perceives him or her.”

People like Yul Kwon, who has been a consultant, lawyer, policy maker, F.C.C. official, Google and Facebook executive, T.V. host, bone-marrow transplant activist, an perhaps most improbably, a winner of the reality show Survivor — all after a childhood of extreme shyness and anxiety. And Nathan Myhrvold, who started college at 14 years old, became a student of Stephen Hawking, a start-up whiz-kid, Microsoft’s first C.T.O. — all while continuing to work as a scientist with published research in paleobiology, climate science, and astronomy, becoming a French-trained chef, author of a James Beard-winning cookbook, serving as a judge on Top Chef, and filing nearly 1,000 patents.

People I (Mostly) Admire is a production of the Freakonomics Radio Network. You can subscribe now on Apple Podcasts, Stitcher, Radio Public, Spotify, or wherever you get your podcasts.

Leidy Klotz on Why the Best Solutions Involve Less — Not More (People I (Mostly) Admire Ep. 45)

When we try to improve things, our first thought is often: What can we add to make this better? But Leidy, a professor of engineering, says we tend to overlook the fact that a better solution might be to take something away. He and Steve talk about examples from Leidy’s book Subtract: The Untapped Science of Less, and from their own lives.

Arne Duncan Says All Kids Deserve a Chance — and Criminals Deserve a Second One (People I (Mostly) Admire Ep. 43)

Former U.S. Secretary of Education, 3x3 basketball champion, and leader of an anti-gun violence organization are all on Arne’s resume. He’s also Steve’s neighbor. The two talk about teachers caught cheating in Chicago public schools and Steve shares a story he’s never told Arne, about a defining moment in the educator’s life.

America’s Math Curriculum Doesn’t Add Up (People I (Mostly) Admire Ep. 42)

A special episode: Steve reports on a passion of his. Most high-school math classes are still preparing students for the Sputnik era. Steve wants to get rid of the “geometry sandwich” and instead have kids learn what they really need in the modern era: data fluency. Originally broadcast on Freakonomics Radio, this episode includes an update from Steve about a project he launched to revamp the education system.

Dr. Bapu Jena on Why Freakonomics Is the Best Medicine (People I (Mostly) Admire Ep. 41)

He’s a Harvard physician and economist who just started a third job: host of the new podcast Freakonomics, M.D. He’s also Steve’s former student. The two discuss why medicine should embrace econ-style research, the ethics of human-challenge trials, and Bapu’s role in one of Steve’s, ahem, less-than-successful experiments.

Harold Pollack on Why Managing Your Money Is as Easy as Taking Out the Garbage (People I (Mostly) Admire Ep. 40)

He argues that personal finance is so simple all you need to know can fit on an index card. How will he deal with Steve’s suggestion that Harold’s nine rules for managing money are overly complicated? Harold and Steve also talk about gun violence — a topic Harold researches as a public-policy professor at the University of Chicago — and they propose some radical ideas for reducing it.

Sendhil Mullainathan Explains How to Generate an Idea a Minute (Part 2) (People I (Mostly) Admire Ep. 38)

Steve continues his conversation with his good friend, MacArthur “Genius Grant” recipient, and fellow University of Chicago economist. Sendhil breaks down the hypothesis of his book Scarcity, explains why machines aren’t competition for human intelligence, and tells Steve why it’s important to appreciate other people’s good ideas before developing your own.

Sendhil Mullainathan Thinks Messing Around Is the Best Use of Your Time (People I (Mostly) Admire Ep. 37)

He’s a professor of computation and behavioral science at the University of Chicago, MacArthur “Genius Grant” recipient, and author. Steve and Sendhil laugh their way through a conversation about the importance of play, the benefits of change, and why we remember so little about the books we’ve read — and how Sendhil’s new app solves this problem.

How Rahm Emanuel Would Run the World (People I (Mostly) Admire Ep. 36)

In this interview, first heard on Freakonomics Radio last year, Steve talks with the former top adviser to presidents Clinton and Obama, about his record — and his reputation. And Rahm explains that while he believes in the power of the federal government, as former mayor of Chicago, he says that cities are where problems really get solved.
