Everyone agrees that massive deforestation is an environmental disaster. But most of the standard solutions — scolding the Brazilians, invoking universal morality — ignore the one solution that might actually work. Originally released on Freakonomics Radio , Steve gives an update on what’s happened in the two years since this episode first ran.
He’s an M.I.T. cosmologist, physicist, and machine-learning expert, and once upon a time, almost an economist. Max and Steve continue their conversation about the existential threats facing humanity, and what Max is doing to mitigate our risk. The co-founder of the Future of Life Institute thinks that artificial intelligence can be the greatest thing to ever happen to humanity — if we don’t screw it up.
How likely is it that this conversation is happening in more than one universe? Should we worry more about Covid or about nuclear war? Is economics a form of “intellectual prostitution?” Steve discusses these questions, and more, with Max, an M.I.T cosmologist, physicist, and machine-learning expert — who was once almost an economist. He also tells Steve why we should be optimistic about the future of humanity (assuming we move Earth to a larger orbit before the sun evaporates our oceans)....
He’s a pioneer of using randomized control experiments in economics — studying the long-term benefits of a $1 health intervention in Africa. Steve asks Edward, a Berkeley professor, about Africa’s long-term economic prospects, and how a parking-ticket-scandal in New York City led to a major finding on corruption around the world.
Playing notes on her piano, she demonstrates for Steve why whole numbers sound pleasing, why octaves are mathematically imperfect, and how math underlies musical composition. Sarah, a professor at the University of London and Gresham College, also talks with Steve about the gender gap in mathematics and why being interested in everything can be a problem.
His childhood dream of playing in the N.B.A. led him to a career as a referee. Marc is one of the league’s top performers after over 20 seasons, but he still reviews every single one of his calls. He talks with Steve about being scrutinized by players, fans, and management; how much work — and data — go into being fair; and why he talks about race with his colleagues and his kids.
It was only in his late twenties that America’s favorite brainiac began to seriously embrace his love of trivia. Jeopardy! ’s newest host also holds the show’s “Greatest of All Time” title. Steve digs into how Ken trained for the show, what it means to have a "geographic memory," and why we lie to our children.
This new Jeopardy! host is best known for playing neurobiologist Amy Farrah Fowler on The Big Bang Theory , but she has a rich life outside of her acting career too, as a teacher, mother — and a real-life neuroscientist. Steve learns more about this one-time academic and Hollywood non-conformist, who is both very similar to him and also quite his opposite.
The prisoner’s dilemma is a classic game-theory problem. Robert, a political scientist at the University of Michigan, has spent his career studying it — and the ways humans can cooperate, or betray each other, for their own benefit. He and Steve talk about the best way to play it and how it shows up in real world situations, from war zones to Steve’s own life.
Steve shows a different side of himself in very personal interviews with his two oldest daughters. Amanda talks about growing up with social anxiety and her decision to not go to college, while Lily speaks candidly about her battle with anorexia and the conversation she had with Steve that led her to finally seek treatment.
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.
An expert on urban economics and co-author of the new book Survival of the City , Ed says cities have faced far worse than Covid. Steve talks with the Harvard professor about why the slums of Mumbai function so well, high-quality housing in China sits empty, and declining cities hang on for so long.
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.
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.
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.
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.
She’s the C.E.O. of Zoox, an autonomous vehicle company. Steve asks Aicha about the big promises the A.V. industry hasn’t yet delivered — and the radical bet Zoox is making on a driverless future. Plus, Steve wants to know how she’s maintained her spark.
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.
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.
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.
He’s been an Arctic scientist, a sports journalist, and is now a best-selling author of science books. His latest, Range: Why Generalists Triumph in a Specialized World , makes the argument that early specialization does not give you a head start in life. David and Steve talk about why frustration is a good sign, and why the 10,000-hour rule is definitely not a rule.
She used to run a behavioral unit in the Obama administration, and now has a similar role at Google. Maya and Steve talk about the power (and limits) of behavioral economics and also how people respond to change — the topic of her new podcast A Slight Change of Plans.
He’s the C.E.O. of the United States Anti-Doping Agency (USADA), which, under his charge, exposed the most celebrated American cyclist as a cheater. And Steve’s been studying cheaters for the last 25 years, so he’s also excited to talk to Travis about the incentives to cheat and the advances in testing technology — and offers his services as an anti-doping data detective for the sport of horse racing.
She’s the author of the bestselling book Grit, and a University of Pennsylvania professor of psychology — a field Steve says he knows nothing about. But once Angela gives Steve a quick tutorial on “goal conflict,” he is suddenly a fan. They also talk parenting, self-esteem, and how easy it is to learn econometrics if you feel like it.
He’s an economist who studies even weirder things than Steve. They discuss whether economics is the best of the social sciences, and why it’s a good idea to get a tattoo of a demand curve on your bicep.
The African-born economist has written four bestselling books, including Dead Aid , which Bill Gates described as “promoting evil.” In her new book about corporate boards, Dambisa uses her experience with global corporations to explore how they can better meet society’s demands. And she explains to Steve why, even as a Harvard and Oxford-educated economist, her goal in life might sound “a little bit like a Miss America pageant.”
Levitt rarely interviews advocates, but the founder of the Good Food Institute is different. Once an outspoken — and sometimes outlandish — animal-rights activist, Bruce has come to believe that market-driven innovation and scientific advancement are the best ways to reduce global meat consumption. Steve and Bruce talk about the negative externalities of factory-farmed meat, and why Bruce gave up antics like streaking at Buckingham Palace.
As a neuroscientist and psychology professor at Columbia University who studies the immediate and long-term effects of illicit substances, Carl Hart believes that all drugs — including heroin, methamphetamines, and cocaine — should be legalized. Steve talks to Carl about his new book, Drug Use for Grown-Ups , and Carl tells Steve why decriminalizing drugs is as American as apple pie.
Nobel laureate, best-selling author, and groundbreaking psychologist Daniel Kahneman is also a friend and former business partner of Steve’s. In discussing Danny’s new book Noise: A Flaw in Human Judgment , the two spar over inconsistencies in criminal sentencing and Danny tells Steve that “Your attitude is unusual” — no surprise there.
He’s one of the world’s leading competitors, having won four U.S. memory tournaments and holding the record for most names memorized in 15 minutes (235!). But Nelson Dellis claims he was born with an average memory and that anyone can learn his tricks. Steve gives Nelson’s techniques a shot, without much hope — and is surprised by the result.
