Freakonomics Radio

Stephen J. Dubner hosts an episode full of the world's most renowned behavior change experts, including Colin Camerer, Ayelet Fishbach, David Laibson, Max Bazerman, Katy Milkman, and Kevin Volpp. Angela Duckworth (psychologist and author of Grit) is our special guest co-host, with Mike Maughan (head of global insights at Qualtrics) as real-time fact-checker.

He's been U.S. Treasury Secretary, a chief economist for the Obama White House and the World Bank, and president of Harvard. He's one of the most brilliant economists of his generation (and perhaps the most irascible). And he thinks the Trump Administration is wrong on just about everything.

A language invented in the 19th century, and meant to be universal, it never really caught on. So why does a group of Esperantists from around the world gather once a year to celebrate their bond?

We explore votes for English, Indonesian, and … Esperanto! The search for a common language goes back millennia, but so much still gets lost in translation. Will technology finally solve that?

There are 7,000 languages spoken on Earth. What are the costs — and benefits — of our modern-day Tower of Babel?

John Urschel was the only player in the N.F.L. simultaneously getting a math Ph.D. at M.I.T. But after a new study came out linking football to brain damage, he abruptly retired. Here's the inside story — and a look at how we make decisions in the face of risk versus uncertainty.

By some estimates, medical error is the third-leading cause of death in the U.S. How can that be? And what's to be done? Our third and final episode in this series offers some encouraging answers.

How do so many ineffective and even dangerous drugs make it to market? One reason is that clinical trials are often run on "dream patients" who aren't representative of a larger population. On the other hand, sometimes the only thing worse than being excluded from a drug trial is being included.

We tend to think of medicine as a science, but for most of human history it has been scientific-ish at best. In the first episode of a three-part series, we look at the grotesque mistakes produced by centuries of trial-and-error, and ask whether the new era of evidence-based medicine is the solution.

Standing in line represents a particularly sloppy — and frustrating — way for supply and demand to meet. Why haven't we found a better way to get what we want? Is it possible that we secretly enjoy waiting in line? And might it even be (gulp) good for us?

The bad news: roughly 70 percent of Americans are financially illiterate. The good news: all the important stuff can fit on one index card. Here's how to become your own financial superhero.

It's hard enough to save for a house, tuition, or retirement. So why are we willing to pay big fees for subpar investment returns? Enter the low-cost index fund. The revolution will not be monetized.

The human foot is an evolutionary masterpiece, far more functional than we give it credit for. So why do we encase it in "a coffin" (as one foot scholar calls it) that stymies so much of its ability — and may create more problems than it solves?

Good intentions are nice, but with so many resources poured into social programs, wouldn't it be even nicer to know what actually works?

Over 40 percent of U.S. births are to unmarried mothers, and the numbers are especially high among the less-educated. Why? One argument is that the decline in good manufacturing jobs led to a decline in "marriageable" men. Surely the fracking boom reversed that trend, right?

How a pain-in-the-neck girl from rural Virginia came to run the most powerful university in the world.

Charles Koch, the mega-billionaire CEO of Koch Industries and half of the infamous political machine, sees himself as a classical liberal. So why do most Democrats hate him so much? In a rare series of interviews, he explains his political awakening, his management philosophy, and why he supports legislation that goes against his self-interest.

Steve Levitt, Scott Turow and Bridget Gainer are panelists. For the "Freakonomics" co-author, the attorney and novelist, and the Cook County commissioner it's "game on!" as they tackle competition of all kinds: athletic, sexual, geopolitical, and the little-known battle between butter and margarine that landed in the Supreme Court. WBEZ's Tricia Bobeda, co-host of the "Nerdette" podcast, is fact-checker.

A breakthrough in genetic technology has given humans more power than ever to change nature. It could help eliminate hunger and disease; it could also lead to the sort of dystopia we used to only read about in sci-fi novels.
