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.

Steve Hilton was the man behind David Cameron's push to remake British politics. Things didn't work out so well there. Now he's trying to launch a new political revolution – from sunny California.

Nearly two percent of America is grassy green. Sure, lawns are beautiful and useful and they smell great. But are the costs — financial, environmental and otherwise — worth the benefits?

A series of academic studies suggest that the wealthy are, to put it bluntly, selfish jerks. It's an easy narrative to swallow — but is it true? A trio of economists set out to test the theory. All it took was a Dutch postal worker's uniform, some envelopes stuffed with cash, and a slight sense of the absurd.

As CEO of Microsoft, Steve Ballmer was famous for over-the-top enthusiasm. Now he's brought that same passion to the N.B.A. -- and to a pet project called USAFacts, which performs a sort of fiscal colonoscopy on the American government.

On the Internet, people say all kinds of things they'd never say aloud -- about sex and race, about their true wants and fears. Seth Stephens-Davidowitz has spent years parsing the data. His conclusion: our online searches are the reflection of our true selves. In the real world, everybody lies.

A kitchen wizard and a nutrition detective talk about the perfect hamburger, getting the most out of garlic, and why you should use vodka in just about everything.

Some people argue that sugar should be regulated, like alcohol and tobacco, on the grounds that it's addictive and toxic. How much sense does that make? We hear from a regulatory advocate, an evidence-based skeptic, a former FDA commissioner — and the organizers of Milktoberfest.

In pursuit of a more perfect economy, we discuss the future of work; the toxic remnants of colonization; and whether giving everyone a basic income would be genius -- or maybe the worst idea ever.

If we could reboot the planet and create new systems and institutions from scratch, would they be any better than what we've blundered our way into through trial and error? This is the first of a series of episodes that we'll release over several months. Today we start with — what else? — economics. You'll hear from Nobel laureate Angus Deaton, the poverty-fighting superhero Jeff Sachs; and many others.

The biggest problem with humanity is humans themselves. Too often, we make choices — what we eat, how we spend our money and time — that undermine our well-being. An all-star team of academic researchers thinks it has the solution: perfecting the science of behavior change. Will it work?

By day, two leaders of Britain's famous Nudge Unit use behavioral tricks to make better government policy. By night, they repurpose those tricks to improve their personal lives. They want to help you do the same.

Hear live journalism wrapped in a game show package and hosted by Stephen J. Dubner. In this episode, Tim Ferriss, Eugene Mirman and Anne Pasternak are panelists. The self-help guru, the comedian and the Brooklyn Museum director talk about brainwaves, sugar, stars and — thanks to fact-checker AJ Jacobs — barf bags.

Economists preach the gospel of "creative destruction," whereby new industries -- and jobs -- replace the old ones. But has creative destruction become too destructive?

Most of us feel we face more headwinds and obstacles than everyone else — which breeds resentment. We also undervalue the tailwinds that help us — which leaves us ungrateful and unhappy. How can we avoid this trap?

The pizza-and-gaming emporium prides itself on affordability, which means its arcade games are really cheap to play. Does that lead to kids hogging the best games — and parents starting those infamous YouTube brawls?

The serial entrepreneur Miki Agrawal loves to talk about the bodily functions that make most people flinch. That's why she's building a business around the three P's: periods, pee, and poop.

In their chase for a global audience, American movie studios spend billions to make their films look amazing. But almost none of those dollars stay in America. What would it take to bring those jobs back -- and would it be worth it?

What happens when a public-health researcher deep in coal country argues that mountaintop mining endangers the entire community? Hint: it doesn't go very well.

The psychologist Angela Duckworth argues that a person's level of stick-to-itiveness is directly related to their level of success. No big surprise there. But grit, she says, isn't something you're born with — it can be learned. Here's how.

We assembled a panel of smart dudes -- a two-time Super Bowl champ; a couple of NFL linemen, including one who's getting a math Ph.D. at MIT; and our resident economist -- to tell you what to watch for, whether you're a football fanatic or a total newbie.

For years, economists promised that global free trade would be mostly win-win. Now they admit the pace of change has been "traumatic." This has already led to a political insurrection -- so what's next?

Just a few decades ago, more than 90 percent of 30-year-olds earned more than their parents had earned at the same age. Now it's only about 50 percent. What happened -- and what can be done about it?

The Daily Show host grew up as a poor, mixed-race South African kid going to three churches every Sunday. So he has a sui generis view of America — especially on race, politics, and religion — and he's not afraid to speak his mind.

Starting in the late 1960s, the Israeli psychologists Amos Tversky and Danny Kahneman began to redefine how the human mind actually works. Michael Lewis's new book The Undoing Project explains how the movement they started -- now known as behavioral economics -- has had such a profound effect on academia, governments, and society at large.

What if the thing we call "talent" is grotesquely overrated? And what if deliberate practice is the secret to excellence? Those are the claims of the research psychologist Anders Ericsson, who has been studying the science of expertise for decades. He tells us everything he's learned.

In this busy time of year, we could all use some tips on how to get more done in less time. First, however, a warning: there's a big difference between being busy and being productive.

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.

The restaurant business model is warped: kitchen wages are too low to hire cooks, while diners are put in charge of paying the waitstaff. So what happens if you eliminate tipping, raise menu prices, and redistribute the wealth? New York restaurant maverick Danny Meyer is about to find out.

Some of our most important decisions are shaped by something as random as the order in which we make them. The gambler's fallacy, as it's known, affects loan officers, federal judges -- and probably you too. How to avoid it? The first step is to admit just how fallible we all are.

"Tell Me Something I Don't Know" is a live game show hosted by Stephen J. Dubner of "Freakonomics Radio." He has always had a mission: to tell you the things you thought you knew but didn't, and things you never thought you wanted to know, but do. Now, with "TMSIDK," he has a new way of doing just that. This new show is still journalism, still factual -- but disguised in the most entertaining, unexpected, and occasionally ridiculous conversation you're likely to hear.Audience contestants come on stage and try to wow a panel of experts with a fascinating fact, a historical wrinkle, a new line of research -- anything, really, as long as it's interesting, useful and true (or at least true-ish). The panel -- an ever-changing mix of comedians, brainiacs, and other high achievers -- poke and prod the contestants, and ultimately choose a winner. And there's a real-time, human fact-checker on hand to filter out the bull.This debut episode features Barnard College president Debora Spar, New York Public Library president Tony Marx, and comedian Andy Zaltzman; Jody Avirgan from FiveThirtyEight handles the fact-checking. You can subscribe now on iTunes. And don't worry, Freakonomics Radio isn't going anywhere -- this is just a special bonus episode of Dubner's new side gig.

Societies where people trust one another are healthier and wealthier. In the U.S. (and the U.K. and elsewhere), social trust has been falling for decades -- in part because our populations are more diverse. What can we do to fix it?

The U.S. president is often called the "leader of free world." But if you ask an economist or a Constitutional scholar how much the occupant of the Oval Office matters, they won't say much. We look at what the data have to say about measuring leadership, and its impact on the economy and the country.

A tiny behavioral-sciences startup is trying to improve the way federal agencies do their work. Considering the size (and habits) of most federal agencies, this isn't so simple. But after a series of early victories -- and a helpful executive order from President Obama -- they are well on their way.

What do Renaissance painting, civil-rights movements, and Olympic cycling have in common? In each case, huge breakthroughs came from taking tiny steps. In a world where everyone is looking for the next moonshot, we shouldn't ignore the power of incrementalism.

Has our culture's obsession with innovation led us to neglect the fact that things also need to be taken care of?

Neuroscientists still have a great deal to learn about the human brain. One recent MRI study sheds some light, finding that a certain kind of storytelling stimulates enormous activity across broad swaths of the brain. The takeaway is obvious: you should be listening to even more podcasts.

The process is famously secretive (and conducted in Swedish!) but we pry the lid off at least a little bit.

It facilitates crime, bribery, and tax evasion -- and yet some governments (including ours) are printing more cash than ever. Other countries, meanwhile, are ditching cash entirely. And if Star Trek is right, we won't have money of any sort in the 24th century.

Sure, we all pay lip service to the Madisonian system of checks and balances. But as one legal scholar argues, presidents have been running roughshod over the system for decades. The result? An accumulation of power that's turned the presidency into a position the founders wouldn't have recognized.

Gary Johnson, the Libertarian Party's presidential candidate, likes to say that most Americans are libertarians but don't know it yet. So why can't Libertarians (and other third parties) gain more political traction?

To you, it's just a ride-sharing app that gets you where you're going. But to an economist, Uber is a massive repository of moment-by-moment data that is helping answer some of the field's most elusive questions.

Internet pioneer Kevin Kelly tries to predict the future by identifying what's truly inevitable. How worried should we be? Yes, robots will probably take your job -- but the future will still be pretty great.
