In one of the earliest Freakonomics Radio episodes (No. 39!), we asked a bunch of economists with young kids how they approached child-rearing. Now the kids are old enough to talk — and they have a lot to say. We hear about nature vs. nurture, capitalism vs. Marxism, and why you sometimes don’t tell your friends that your father is an economist.

Arthur Brooks is an economist who for 10 years ran the American Enterprise Institute, one of the most influential conservative think tanks in the world. He has come to believe there is only one weapon that can defeat our extreme political polarization: love. Is Brooks a fool for thinking this — and are you perhaps his kind of fool?

Breaking news! Sources say American journalism exploits our negativity bias to maximize profits, and social media algorithms add fuel to the fire. Stephen Dubner investigates.

Verbal tic or strategic rejoinder? Whatever the case: it’s rare to come across an interview these days where at least one question isn’t a “great” one.  

The N.B.A. superstar Chris Bosh was still competing at the highest level when a blood clot abruptly ended his career. In his new book, Letters to a Young Athlete, Bosh covers the highlights and the struggles. In this installment of the Freakonomics Radio Book Club, he talks with guest host Angela Duckworth.

The U.S. is an outlier when it comes to policing, as evidenced by more than 1,000 fatal shootings by police each year. But we’re an outlier in other ways too: a heavily-armed populace, a fragile mental-health system, and the fact that we spend so much time in our cars. Add in a history of racism and it’s no surprise that barely half of all Americans have a lot of confidence in the police. So what if we start to think about policing as … philanthropy?

Among O.E.C.D. nations, the U.S. has one of the highest rates of child poverty. How can that be? To find out, Stephen Dubner speaks with a Republican senator, a Democratic mayor, and a large cast of econo-nerds. Along the way, we hear some surprisingly good news: Washington is finally ready to attack the problem head-on.

When Richard Thaler published Nudge in 2008 (with co-author Cass Sunstein), the world was just starting to believe in his brand of behavioral economics. How did nudge theory hold up in the face of a global financial meltdown, a pandemic, and other existential crises? With the publication of a new, radically updated edition, Thaler tries to persuade Stephen Dubner that nudging is more relevant today than ever.

That’s what some health officials are saying, but the data aren’t so clear. We look into what’s known (and not known) about the prevalence and effects of loneliness — including the possible upsides.

In a conversation fresh from the Freakonomics Radio Network’s podcast laboratory, Michèle Flournoy (one of the highest-ranking women in Defense Department history) speaks with Cecil Haney (one of the U.S. Navy’s first Black four-star admirals) about nuclear deterrence, smart leadership, and how to do inclusion right.

Humans have a built-in “negativity bias,” which means we give bad news much more power than good. Would the Covid-19 crisis be an opportune time to reverse this tendency?

Air pollution is estimated to cause 7 million deaths a year and cost the global economy nearly $3 trillion. But is the true cost even higher? Stephen Dubner explores the links between pollution and cognitive function, and enlists two fellow Freakonomics Radio Network hosts in a homegrown experiment.

While other countries seem to build spectacular bridges, dams, and even entire cities with ease, the U.S. is stuck in pothole-fixing mode. We speak with an array of transportation nerds — including the secretary of transportation and his immediate predecessor — to see if a massive federal infrastructure package can put America back in the driver’s seat.

The environmentalists say we’re doomed if we don’t drastically reduce consumption. The technologists say that human ingenuity can solve just about any problem. A debate that’s been around for decades has become a shouting match. Is anyone right?

According to a decades-long research project, the U.S. is not only the most individualistic country on earth; we’re also high on indulgence, short-term thinking, and masculinity (but low on “uncertainty avoidance,” if that makes you feel better). We look at how these traits affect our daily lives and why we couldn’t change them even if we wanted to.

We often look to other countries for smart policies on education, healthcare, infrastructure, etc. But can a smart policy be simply transplanted into a country as culturally unusual (and as supremely WEIRD) as America?

The benefits of sleep are by now well established, and yet many people don’t get enough. A new study suggests we should channel our inner toddler and get 30 minutes of shut-eye in the afternoon. But are we ready for a napping revolution?

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?

Bren Smith, who grew up fishing and fighting, is now part of a movement that seeks to feed the planet while putting less environmental stress on it. He makes his argument in a book called Eat Like a Fish; his secret ingredient: kelp. But don’t worry, you won’t have to eat it (not much, at least). An installment of The Freakonomics Radio Book Club.

Cecilia Rouse, the chair of the White House Council of Economic Advisors, is as cold-blooded as any economist. But she admits that her profession would do well to focus on policy that actually helps people. Rouse explains why President Biden wants to spend trillions of dollars to reshape the economy, and why — as the first Black chair of the C.E.A. — she has a good idea of what needs fixing.

Bapu Jena was already a double threat: a doctor who’s also an economist. Now he’s a podcast host too. In this sneak preview of the Freakonomics Radio Network’s newest show, Bapu discovers that marathons can be deadly — but not for the reasons you may think.

The pandemic may be winding down, but that doesn’t mean we’ll return to full-time commuting and packed office buildings. The greatest accidental experiment in the history of labor has lessons to teach us about productivity, flexibility, and even reversing the brain drain. But don’t buy another dozen pairs of sweatpants just yet.

The social psychologist Robert Cialdini is a pioneer in the science of persuasion. His 1984 book Influence is a classic, and he has just published an expanded and revised edition. In this episode of the Freakonomics Radio Book Club, he gives a master class in the seven psychological levers that bewitch our rational minds and lead us to buy, behave, or believe without a second thought.

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?

The man who wants America to “think harder” has parlayed his quixotic presidential campaign into front-runner status in New York’s mayoral election. And he has some big plans.

It’s true that robots (and other smart technologies) will kill many jobs. It may also be true that newer collaborative robots (“cobots”) will totally reinvigorate how work gets done. That, at least, is what the economists are telling us. Should we believe them?

Backers of a $15 federal wage say it’s a no-brainer if you want to fight poverty. Critics say it’s a blunt instrument that leads to job loss. Even the economists can’t agree! We talk to a bunch of them — and a U.S. Senator — to sort it out, and learn there’s a much bigger problem to worry about.

The state-by-state rollout of legalized weed has given economists a perfect natural experiment to measure its effects. Here’s what we know so far — and don’t know — about the costs and benefits of legalization.

In this special crossover episode, People I (Mostly) Admire host Steve Levitt admits to No Stupid Questions co-host Angela Duckworth that he knows almost nothing about psychology. 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.

Kidney failure is such a catastrophic (and expensive) disease that Medicare covers treatment for anyone, regardless of age. Since Medicare reimbursement rates are fairly low, the dialysis industry had to find a way to tweak the system if they wanted to make big profits. They succeeded.

Medicine has evolved from a calling into an industry, adept at dispensing procedures and pills (and gigantic bills), but less good at actual health. Most reformers call for big, bold action. What happens if, instead, you think small?

Why do so many promising solutions — in education, medicine, criminal justice, etc. — fail to scale up into great policy? And can a new breed of “implementation scientists” crack the code?

In a word: networks. Once it embraced information as its main currency, New York was able to climb out of a deep fiscal (and psychic) pit. Will that magic trick still work after Covid? In this installment of the Freakonomics Radio Book Club, guest host Kurt Andersen interviews Thomas Dyja, author of New York, New York, New York: Four Decades of Success, Excess and Transformation.

Behavioral scientists have been exploring if — and when — a psychological reset can lead to lasting change. We survey evidence from the London Underground, Major League Baseball, and New Year’s resolutions; we look at accidental fresh starts, forced fresh starts, and fresh starts that backfire. And we wonder: will the pandemic’s end provide the biggest fresh start ever?

Americans are so accustomed to the standard intersection that we rarely consider how dangerous it can be — as well as costly, time-wasting, and polluting. Is it time to embrace the lowly, lovely roundabout?

New York Times columnist Charles Blow argues that white supremacy in America will never fully recede, and that it’s time for Black people to do something radical about it. In The Devil You Know: A Black Power Manifesto, he urges a “reverse migration” to the South to consolidate political power and create a region where it’s safe to be Black. (This is an episode of the Freakonomics Radio Book Club.)

Researchers are trying to figure out who gets bored — and why — and what it means for ourselves and the economy. But maybe there’s an upside to boredom?

Not so long ago, G.E. was the most valuable company in the world, a conglomerate that included everything from light bulbs and jet engines to financial services and The Apprentice. Now it’s selling off body parts to survive. What does the C.E.O. who presided over the decline have to say for himself?

Most of us are are afraid to ask sensitive questions about money, sex, politics, etc. New research shows this fear is largely unfounded. Time for some interesting conversations!

Caitlin Doughty is a mortician who would like to put herself out of business. Our corporate funeral industry, she argues, has made us forget how to offer our loved ones an authentic sendoff. Doughty is the author of Smoke Gets in Your Eyes: And Other Lessons From the Crematory. In this installment of the Freakonomics Radio Book Club, she is interviewed by guest host Maria Konnikova.

For all the progress made in fighting cancer, it still kills 10 million people a year, and some types remain especially hard to detect and treat. Pancreatic cancer, for instance, is nearly always fatal. A new clinical-trial platform could change that by aligning institutions that typically compete against one another.

It’s a powerful biological response that has preserved our species for millennia. But now it may be keeping us from pursuing strategies that would improve the environment, the economy, even our own health. So is it time to dial down our disgust reflex? You can help fix things — as Stephen Dubner does in this episode — by chowing down on some delicious insects.

They can’t vote or hire lobbyists. The policies we create to help them aren’t always so helpful. Consider the car seat: parents hate it, the safety data are unconvincing, and new evidence suggests an unintended consequence that is as anti-child as it gets.

We’ve collected some of our favorite moments from People I (Mostly) Admire, the latest show from the Freakonomics Radio Network. Host Steve Levitt seeks advice from scientists and inventors, memory wizards and basketball champions — even his fellow economists. He also asks about quitting, witch trials, and whether we need a Manhattan Project for climate change.

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?

In this episode of No Stupid Questions — a Freakonomics Radio Network show launched earlier this year — Stephen Dubner and Angela Duckworth debate why we watch, read, and eat familiar things during a crisis, and if it might in fact be better to try new things instead. Also: is a little knowledge truly as dangerous as they say?

Patients in the U.S. healthcare system often feel they’re treated with a lack of empathy. Doctors and nurses have tragically high levels of burnout. Could fixing the first problem solve the second? And does the rest of society need more compassion too?

The incoming president argues that the economy and the environment are deeply connected. This is reflected in his choice for National Economic Council director — Brian Deese, a climate-policy wonk and veteran of the no-drama-Obama era. But don’t mistake Deese’s lack of drama for a lack of intensity.

Tony Hsieh, the longtime C.E.O. of Zappos, was an iconoclast and a dreamer. Five years ago, we sat down with him around a desert campfire to talk about those dreams. Hsieh died recently from injuries sustained in a house fire; he was 46.

G.M. produces more than 20 times as many cars as Tesla, but Tesla is worth nearly 10 times as much. Mary Barra, the C.E.O. of G.M., is trying to fix that. We speak with her about the race toward an electrified (and autonomous) future, China and Trump, and what it’s like to be the “fifth-most powerful woman in the world.”

Google and Facebook are worth a combined $2 trillion, with the vast majority of their revenue coming from advertising. In our previous episode, we learned that TV advertising is much less effective than the industry says. Is digital any better? Some say yes, some say no — and some say we’re in a full-blown digital-ad bubble.

Companies around the world spend more than half-a-trillion dollars each year on ads. The ad industry swears by its efficacy — but a massive new study tells a different story.

The modern world overwhelms us with sounds we didn’t ask for, like car alarms and cell-phone “halfalogues.” What does all this noise cost us in terms of productivity, health, and basic sanity?

John Mackey, the C.E.O. of Whole Foods, has learned the perils of speaking his mind. But he still says what he thinks about everything from “conscious leadership” to the behavioral roots of the obesity epidemic. He also argues for a style of capitalism and politics that at this moment seems like a fantasy. What does he know that we don’t?

The sociologist Sudhir Venkatesh spent years studying crack dealers, sex workers, and the offspring of billionaires. Then he wandered into an even stranger world: social media. He spent the past five years at Facebook and Twitter. Now that he’s back in the real world, he’s here to tell us how the digital universe really works. In this pilot episode of a new podcast, Venkatesh interviews the progressive political operative Tara McGowan about her digital successes with the Obama campaign, her noisy failure with the Iowa caucus app, and why the best way for Democrats to win more elections was to copy the Republicans.

A fine reading of most policies for “business interruption” reveals that viral outbreaks aren’t covered. Some legislators are demanding that insurance firms pay up anyway. Is it time to rethink insurance entirely?

As beloved and familiar as they are, we rarely stop to consider life from the dog’s point of view. That stops now. In this latest installment of the Freakonomics Radio Book Club, we discuss Inside of a Dog with the cognitive scientist (and dog devotee) Alexandra Horowitz.

It isn’t just supply and demand. We look at the complicated history and skewed incentives that make “affordable housing” more punch line than reality in cities from New York and San Francisco to Flint, Michigan (!).

The pandemic has hit America's biggest city particularly hard. Amidst a deep fiscal hole, rising homicides, and a flight to the suburbs, some people think the city is heading back to the bad old 1970s. We look at the history — and the data — to see why that’s probably not the case.

It was only in his late twenties that America’s favorite brainiac began to seriously embrace his love of trivia. Now he holds the “Greatest of All Time” title on Jeopardy! Steve Levitt digs into how he trained for the show, what it means to have a "geographic memory," and why we lie to our children.

Three leading researchers from the Mount Sinai Health System discuss how ketamine, cannabis, and ecstasy are being used (or studied) to treat everything from severe depression to addiction to PTSD. We discuss the upsides, downsides, and regulatory puzzles.

The families of U.S. troops killed and wounded in Afghanistan are suing several companies that did reconstruction there. Why? These companies, they say, paid the Taliban protection money, which gave them the funding — and opportunity — to attack U.S. soldiers instead. A look at the messy, complicated, and heart-breaking tradeoffs of conflict-zone economies.

The dean of Yale’s School of Management grew up in a small village in Guyana. During his unlikely journey, he has researched video-gaming habits, communicable disease, and why so many African-Americans haven’t had the kind of success he’s had. Steve Levitt talks to Charles about his parents’ encouragement, his love of Sports Illustrated, and how he talks to his American-born kids about the complicated history of Blackness in America.

Trump says it would destroy us. Biden needs the voters who support it (especially the Bernie voters). The majority of millennials would like it to replace capitalism. But what is “it”? We bring in the economists to sort things out and tell us what the U.S. can learn from the good (and bad) experiences of other (supposedly) socialist countries.

Netflix co-founder Reed Hastings came to believe that corporate rules can kill creativity and innovation. In this latest edition of the Freakonomics Radio Book Club, guest host Maria Konnikova talks to Hastings about his new book, No Rules Rules, and why for some companies the greatest risk is taking no risks at all.

Thanks to daily Covid testing and regimented protocols, the new football season is underway. Meanwhile, most teachers, students, and parents are essentially waiting for the storm to pass. And school isn’t even a contact sport (usually).

She’s best known for playing neurobiologist Amy Farrah Fowler on The Big Bang Theory, but the award-winning actress has a rich life outside of her acting career, as a teacher, mother — and a real-life neuroscientist. Steve Levitt tries to learn more about this one-time academic and Hollywood non-conformist, who is both very similar to him and also quite his opposite.

We all know our political system is “broken” — but what if that’s not true? Some say the Republicans and Democrats constitute a wildly successful industry that has colluded to kill off competition, stifle reform, and drive the country apart. So what are you going to do about it?

We explore the science, scalability, and (of course) economics surrounding the global vaccine race. Guests include the chief medical officer of the first U.S. firm to go to Phase 3 trials with a vaccine candidate; a former F.D.A. commissioner who’s been warning of a pandemic for years; and an economist who thinks Covid-19 may finally change how diseases are cured.

A new interview show with host Steve Levitt. Today he speaks with the Harvard psychologist and linguist Steven Pinker. By cataloging the steady march of human progress, the self-declared “polite Canadian” has managed to enrage people on opposite ends of the political spectrum. Levitt tries to understand why.

What happens when tens of millions of fantasy-sports players are suddenly able to bet real money on real games? We’re about to find out. A recent Supreme Court decision has cleared the way to bring an estimated $300 billion in black-market sports betting into the light. We sort out the winners and losers.

The endless pursuit of G.D.P., argues the economist Kate Raworth, shortchanges too many people and also trashes the planet. Economic theory, she says, “needs to be rewritten” — and Raworth has tried, in a book called Doughnut Economics. It has found an audience among reformers, and now the city of Amsterdam is going whole doughnut.

Aisle upon aisle of fresh produce, cheap meat, and sugary cereal — a delicious embodiment of free-market capitalism, right? Not quite. The supermarket was in fact the endpoint of the U.S. government’s battle for agricultural abundance against the U.S.S.R. Our farm policies were built to dominate, not necessarily to nourish — and we are still living with the consequences.

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

Most Americans agree that racial discrimination has been, and remains, a big problem. But that is where the agreement ends.

The racial wealth gap in the U.S. is massive. We explore the causes, consequences, and potential solutions. Also: another story of discrimination and economic disparity, this one perpetrated by an international sporting authority. The first of a two-part series.

Christina Romer was a top White House economist during the Great Recession. As a researcher, she specializes in the Great Depression. She tells us what those disasters can (and can’t) teach us about the Covid crash.

Before she decided to become a poker pro, Maria Konnikova didn’t know how many cards are in a deck. But she did have a Ph.D. in psychology, a brilliant coach, and a burning desire to know whether life is driven more by skill or chance. She found some answers in poker — and in her new book The Biggest Bluff, she’s willing to tell us everything she learned.

Thanks to the pandemic, the telehealth revolution we’ve been promised for decades has finally arrived. Will it stick? Will it cut costs — and improve outcomes? We ring up two doctors and, of course, an economist to find out.

In this new addition to the Freakonomics Radio Network, co-hosts Stephen Dubner and Angela Duckworth discuss the relationship between age and happiness. Also: does all creativity come from pain? New episodes of "No Stupid Questions" are released every Sunday evening — please subscribe wherever you get your podcasts.

Millions and millions are out of work, with some jobs never coming back. We speak with four economists — and one former presidential candidate — about the best policy options and the lessons (good and bad) from the past.

Covid-19 is the biggest job killer in a century. As the lockdown eases, what does re-employment look like? Who will be first and who last? Which sectors will surge and which will disappear? Welcome to the Great Labor Reallocation of 2020.

In the U.S. alone, we hold 55 million meetings a day. Most of them are woefully unproductive, and tyrannize our offices. The revolution begins now — with better agendas, smaller invite lists, and an embrace of healthy conflict.

The accidental futurist Kevin Kelly on why enthusiasm beats intelligence, how to really listen, and why the solution to bad technology is more technology.

Three university presidents try to answer our listeners’ questions. The result? Not much pomp and a whole lot of circumstance.

Humans have a built-in “negativity bias,” which means we give bad news much more power than good. Would the Covid-19 crisis be an opportune time to reverse this tendency?

We speak with a governor, a former C.D.C. director, a pandemic forecaster, a hard-charging pharmacist, and a pair of economists — who say it’s all about the incentives. (Pandemillions, anyone?)

As a former top adviser to presidents Clinton and Obama, he believes in the power of the federal government. But as former mayor of Chicago, he says that cities are where real problems get solved — especially in the era of Covid-19.

The U.S. spent the past few decades waiting for China to act like the global citizen it said it wanted to be. The waiting may be over.

Should a nurse or doctor who gets sick treating Covid-19 patients have priority access to a potentially life-saving healthcare device? Americans aren’t used to rationing in medicine, but it’s time to think about it. We consult a lung specialist, a bioethicist, and (of course) an economist.

Covid-19 has shocked our food-supply system like nothing in modern history. We examine the winners, the losers, the unintended consequences — and just how much toilet paper one household really needs.

Congress just passed the biggest aid package in modern history. We ask six former White House economic advisors and one U.S. Senator: Will it actually work? What are its best and worst features? Where does $2 trillion come from, and what are the long-term effects of all that government spending?

There are a lot of upsides to urban density — but viral contagion is not one of them. Also: a nationwide lockdown will show if familiarity really breeds contempt. And: how to help your neighbor.

In just a few weeks, the novel coronavirus has undone a century’s worth of our economic and social habits. What consequences will this have on our future — and is there a silver lining in this very black pandemic cloud?

As cities become ever-more expensive, politicians and housing advocates keep calling for rent control. Economists think that’s a terrible idea. They say it helps a small (albeit noisy) group of renters, but keeps overall rents artificially high by disincentivizing new construction. So what happens next?

Trump says it would destroy us. Sanders says it will save us. The majority of millennials would like it to replace capitalism. But what is “it”? We bring in the economists to sort things out and tell us what the U.S. can learn from the good (and bad) experiences of other (supposedly) socialist countries.

That’s what some health officials are saying, but the data aren’t so clear. We look into what’s known (and not known) about the prevalence and effects of loneliness — including the possible upsides.

When he became chairman of the Federal Communications Commission, Ajit Pai announced that he was going to take a “weed whacker” to Obama-era regulations. So far, he’s kept his promise, and earned the internet’s ire for reversing the agency’s position on net neutrality. Pai defends his actions and explains how the U.S. can “win” everything from the 5G race to the war on robocalls.

Why do so many promising solutions — in education, medicine, criminal justice, etc. — fail to scale up into great policy? And can a new breed of “implementation scientists” crack the code?

We asked this same question nearly a decade ago. The answer then: probably not. But a lot has changed since then, and we’re three years into one of the most anomalous presidencies in American history. So once again we try to sort out presidential signal from noise. What we hear from legal and policy experts may leave you surprised, befuddled — and maybe infuriated.

One of the most storied (and valuable) sports franchises in the world had fallen far. So they decided to do a full reboot — and it worked: this week, they are headed back to the Super Bowl. Before the 2018 season, we sat down with the team’s owner, head coach, general manager, and players as they were plotting their turnaround. Here’s an update of that episode.

One prescription drug is keeping some addicts from dying. So why isn’t it more widespread? A story of regulation, stigma, and the potentially fatal faith in abstinence.

How pharma greed, government subsidies, and a push to make pain the “fifth vital sign” kicked off a crisis that costs $80 billion a year and has killed hundreds of thousands of Americans.

We all like to throw around terms that describe human behavior — “bystander apathy” and “steep learning curve” and “hard-wired.” Most of the time, they don’t actually mean what we think they mean. But don’t worry — the experts are getting it wrong, too.

There is strong evidence that exercise is wildly beneficial. There is even stronger evidence that most people hate to exercise. So if a pill could mimic the effects of working out, why wouldn’t we want to take it?

In a special holiday episode, Stephen Dubner and Angela Duckworth take turns asking each other questions about charisma, wealth vs. intellect, and (of course) grit.

A year ago, nobody was taking Andrew Yang very seriously. Now he is America’s favorite entrepre-nerd, with a candidacy that keeps gaining momentum. This episode includes our Jan. 2019 conversation with the leader of the Yang Gang and a fresh interview recorded from the campaign trail in Iowa.

Every year, Americans short the I.R.S. nearly half a trillion dollars. Most ideas to increase compliance are more stick than carrot — scary letters, audits, and penalties. But what if we gave taxpayers a chance to allocate how their money is spent, or even bribed them with a thank-you gift?

Innovation experts have long overlooked where a lot of innovation actually happens. The personal computer, the mountain bike, the artificial pancreas — none of these came from some big R&D lab, but from users tinkering in their homes. Acknowledging this reality — and encouraging it — would be good for the economy (and the soul too).

There are a lot of barriers to changing your mind: ego, overconfidence, inertia — and cost. Politicians who flip-flop get mocked; family and friends who cross tribal borders are shunned. But shouldn’t we be encouraging people to change their minds? And how can we get better at it ourselves?

A recent outbreak of illness and death has gotten everyone’s attention — including late-to-the-game regulators. But would a ban on e-cigarettes do more harm than good? We smoke out the facts.

For nearly a decade, governments have been using behavioral nudges to solve problems — and the strategy is catching on in healthcare, firefighting, and policing. But is that thinking too small? Could nudging be used to fight income inequality and achieve world peace? Recorded live in London, with commentary from Andy Zaltzman (The Bugle).

It’s an acutely haphazard way of paying workers, and yet it keeps expanding. We dig into the data to find out why.

Do economic sanctions work? Are big democracies any good at spreading democracy? What is the root cause of terrorism? It turns out that data analysis can help answer all these questions — and make better foreign-policy decisions. Guests include former Department of Defense officials Chuck Hagel and Michèle Flournoy and Chicago Project on Security and Threats researchers Robert Pape and Paul Poast. Recorded live in Chicago; Steve Levitt is co-host.

For decades, there’s been a huge gender disparity both on-screen and behind the scenes. But it seems like cold, hard data — with an assist from the actor Geena Davis — may finally be moving the needle.

It used to be a global capital of innovation, invention, and exploration. Now it’s best known for its messy European divorce. We visit London to see if the British spirit of discovery is still alive. Guests include the mayor of London, undersea explorers, a time-use researcher, and a theoretical physicist who helped Liverpool win the Champions League. Dan Schreiber from No Such Thing as a Fish rides shotgun.

In 2016, David Cameron held a referendum on whether the U.K. should stay in the European Union. A longtime Euroskeptic, he nevertheless led the Remain campaign. So what did Cameron really want? We ask him that and much more — including why he left office as soon as his side lost and what he’d do differently if given another chance. (Hint: not much.)

Most high-school math classes are still preparing students for the Sputnik era. Steve Levitt wants to get rid of the “geometry sandwich” and instead have kids learn what they really need in the modern era: data fluency.

Mary Daly rose from high-school dropout to president of the Federal Reserve Bank of San Francisco. She thinks the central bank needs an upgrade too. It starts with recognizing that the economy is made up of actual humans.

In the U.S. alone, we hold 55 million meetings a day. Most of them are woefully unproductive, and tyrannize our offices. The revolution begins now — with better agendas, smaller invite lists, and an embrace of healthy conflict.

It began as a post-war dream for a more collaborative and egalitarian workplace. It has evolved into a nightmare of noise and discomfort. Can the open office be saved, or should we all just be working from home?

What happens when tens of millions of fantasy-sports players are suddenly able to bet real money on real games? We’re about to find out. A recent Supreme Court decision has cleared the way to bring an estimated $300 billion in black-market sports betting into the light. We sort out the winners and losers.

Global demand for beef, chicken, and pork continues to rise. So do concerns about environmental and other costs. Will reconciling these two forces be possible — or, even better, Impossible™?

The quirky little grocery chain with California roots and German ownership has a lot to teach all of us about choice architecture, efficiency, frugality, collaboration, and team spirit.

Research shows that having a distinctively black name doesn’t affect your economic future. But what is the day-to-day reality of living with such a name? Marijuana Pepsi Vandyck, a newly-minted Ph.D., is well-qualified to answer this question. Her verdict: the data don’t tell the whole story.

A kid’s name can tell us something about his parents — their race, social standing, even their politics. But is your name really your destiny?

Aisle upon aisle of fresh produce, cheap meat, and sugary cereal — a delicious embodiment of free-market capitalism, right? Not quite. The supermarket was in fact the endpoint of the U.S. government’s battle for agricultural abundance against the U.S.S.R. Our farm policies were built to dominate, not necessarily to nourish — and we are still living with the consequences.

We all know our political system is “broken” — but what if that’s not true? Some say the Republicans and Democrats constitute a wildly successful industry that has colluded to kill off competition, stifle reform, and drive the country apart. So what are you going to do about it?

They — along with a great many other high-achieving women — were all once Girl Scouts. So was Sylvia Acevedo. Raised in a poor, immigrant family, she was told that “girls like her” didn’t go to college. But she did, and then became a rocket scientist and tech executive. Now she’s C.E.O. of the very organization she credits with shaping her life. Acevedo tells us how the Girl Scouts are trying to stay relevant, why they’re suing the Boy Scouts, and how they sell so many cookies.

The controversial theory linking Roe v. Wade to a massive crime drop is back in the spotlight as several states introduce abortion restrictions. Steve Levitt and John Donohue discuss their original research, the challenges to its legitimacy, and their updated analysis. Also: what this means for abortion policy, crime policy, and having intelligent conversations about contentious topics.

Takeru Kobayashi revolutionized the sport of competitive eating. What can the rest of us learn from his breakthrough?

There is strong evidence that exercise is wildly beneficial. There is even stronger evidence that most people hate to exercise. So if a pill could mimic the effects of working out, why wouldn’t we want to take it?

An all-star team of behavioral scientists discovers that humans are stubborn (and lazy, and sometimes dumber than dogs). We also hear about binge drinking, humblebragging, and regrets. Recorded live in Philadelphia with guests including Richard Thaler, Angela Duckworth, Katy Milkman, and Tom Gilovich.

Recorded live in San Francisco. Guests include the keeper of a 10,000-year clock, the co-founder of Lyft, a pioneer in male birth control, a specialist in water security, and a psychology professor who is also a puppy. With co-host Angela Duckworth, fact-checker Mike Maughan, and the Freakonomics Radio Orchestra.

Recorded live in Los Angeles. Guests include Mayor Eric Garcetti, the “Earthquake Lady,” the head of the Port of L.A., and a scientist with NASA’s Planetary Protection team. With co-host Angela Duckworth, fact-checker Mike Maughan, and the worldwide debut of Luis Guerra and the Freakonomics Radio Orchestra.

There are a lot of barriers to changing your mind: ego, overconfidence, inertia — and cost. Politicians who flip-flop get mocked; family and friends who cross tribal borders are shunned. But shouldn’t we be encouraging people to change their minds? And how can we get better at it ourselves?

Whether it’s a giant infrastructure plan or a humble kitchen renovation, it’ll inevitably take way too long and cost way too much. That’s because you suffer from “the planning fallacy.” (You also have an “optimism bias” and a bad case of overconfidence.) But don’t worry: we’ve got the solution.

The revolution in home DNA testing is giving consumers important, possibly life-changing information. It’s also building a gigantic database that could lead to medical breakthroughs. But how will you deal with upsetting news? What if your privacy is compromised? And are you prepared to have your DNA monetized? We speak with Anne Wojcicki, founder and C.E.O. of 23andMe.

As the cost of college skyrocketed, it created a debt burden that’s putting a drag on the economy. One possible solution: shifting the risk of debt away from students and onto investors looking for a cut of the graduates’ earning power.

Humans have been having kids forever, so why are modern parents so bewildered? The economist Emily Oster marshals the evidence on the most contentious topics — breastfeeding and sleep training, vaccines and screen time — and tells her fellow parents to calm the heck down.

Humans, it has long been thought, are the only animal to engage in economic activity. But what if we've had it exactly backward?

The banana used to be a luxury good. Now it’s the most popular fruit in the U.S. and elsewhere. But the production efficiencies that made it so cheap have also made it vulnerable to a deadly fungus that may wipe out the one variety most of us eat. Scientists do have a way to save it — but will Big Banana let them?

Daniel Ek, a 23-year-old Swede who grew up on pirated music, made the record labels an offer they couldn’t refuse: a legal platform to stream all the world’s music. Spotify reversed the labels’ fortunes, made Ek rich, and thrilled millions of music fans. But what has it done for all those musicians stuck in the long tail?

As cities become ever-more expensive, politicians and housing advocates keep calling for rent control. Economists think that’s a terrible idea. They say it helps a small (albeit noisy) group of renters, but keeps overall rents artificially high by disincentivizing new construction. So what happens next?

What your disgust level says about your politics, how Napoleon influenced opera, why New York City’s subways may finally run on time, and more. Five compelling guests tell Stephen Dubner, co-host Angela Duckworth, and fact-checker Jody Avirgan lots of things they didn’t know.

Kenji Lopez-Alt became a rock star of the food world by bringing science into the kitchen in a way that everyday cooks can appreciate. Then he dared to start his own restaurant — and discovered problems that even science can’t solve.

For years, Gary Cohn thought he’d be the next C.E.O. of Goldman Sachs. Instead, he became the “adult in the room” in a chaotic administration. Cohn talks about the fights he won, the fights he lost, and the fights he was no longer willing to have. Also: why he and Trump are still on speaking terms even after he reportedly called the president “a professional liar.”

The road to success is paved with failure, so you might as well learn to do it right. (Ep. 5 of the “How to Be Creative” series.)

Whether you’re building a business or a cathedral, execution is everything. We ask artists, scientists, and inventors how they turned ideas into reality. And we find out why it’s so hard for a group to get things done — and what you can do about it. (Ep. 4 of the “How to Be Creative” series.)

Whether you’re mapping the universe, hosting a late-night talk show, or running a meeting, there are a lot of ways to up your idea game. Plus: the truth about brainstorming. (Ep. 3 of the “How to Be Creative” series.)

Global demand for beef, chicken, and pork continues to rise. So do concerns about environmental and other costs. Will reconciling these two forces be possible — or, even better, Impossible™?

In 2005, Raghuram Rajan said the financial system was at risk “of a catastrophic meltdown.” After stints at the I.M.F. and India’s central bank, he sees another potential crisis — and he offers a solution. Is it stronger governments? Freer markets? Rajan’s answer: neither.

Stephen Dubner’s conversation with the former N.F.L. player, union official, and all-around sports thinker, recorded for our “Hidden Side of Sports” series.

If you think talent and hard work give top athletes all the leverage to succeed, think again. As employees in the Sports-Industrial Complex, they’ve got a tight earnings window, a high injury rate, little choice in where they work — and a very early forced retirement. (Ep. 6 of “The Hidden Side of Sports” series.)

A conversation with the Shark Tank star, entrepreneur, and Dallas Mavericks owner recorded for the Freakonomics Radio series “The Hidden Side of Sports.”

For most of us, the athletes are what make sports interesting. But if you own the team or run the league, your players are essentially very expensive migrant workers who eat into your profits. We talk to N.F.L., N.B.A., and U.F.C. executives about labor costs, viewership numbers, legalized gambling, and the rise of e-sports. (Ep. 5 of “The Hidden Side of Sports” series.)

A conversation with former Major League Baseball player and current ESPN analyst Mark Teixeira, recorded for the Freakonomics Radio series “The Hidden Side of Sports.”

Great athletes aren’t just great at the physical stuff. They’ve also learned how to handle pressure, overcome fear, and stay focused. Here’s the good news: you don’t have to be an athlete to use what they know. (Ep. 4 of “The Hidden Side of Sports” series.)

Jim Yong Kim has an unorthodox background for a World Bank president — and his reign has been just as unorthodox. He has just announced he’s stepping down, well before his term is over; we recorded this interview with him in 2015.

In the American Dream sweepstakes, Andrew Yang was a pretty big winner. But for every winner, he came to realize, there are thousands upon thousands of losers — a “war on normal people,” he calls it. Here’s what he plans to do about it.

The U.N.’s World Happiness Report — created to curtail our unhealthy obsession with G.D.P. — is dominated every year by the Nordic countries. We head to Denmark to learn the secrets of this happiness epidemic (and to see if we should steal them).

Games are as old as civilization itself, and some people think they have huge social value regardless of whether you win or lose. Tom Whipple is not one of those people. That’s why he consulted an army of preposterously overqualified experts to find the secret to winning any game.

You wouldn’t think you could win a Nobel Prize for showing that humans tend to make irrational decisions. But that’s what Richard Thaler has done. The founder of behavioral economics describes his unlikely route to success; his reputation for being lazy; and his efforts to fix the world — one nudge at a time.

Celebrity chef Alex Guarnaschelli joins us to co-host an evening of delicious fact-finding: where a trillion oysters went, whether a soda tax can work, and how beer helped build an empire. Washington Post columnist Alexandra Petri is our real-time fact-checker.

Our co-host is comedian Christian Finnegan, and we learn: the difference between danger and fear; the role of clouds in climate change; and why (and when) politicians are bad at math. Washington Post columnist Alexandra Petri is our real-time fact-checker.

We learn how to be less impatient, how to tell fake news from real, and the simple trick that nurses used to make better predictions than doctors. Journalist Manoush Zomorodi co-hosts; our real-time fact-checker is the author and humorist A.J. Jacobs.

Our co-host is Grit author Angela Duckworth, and we learn fascinating, Freakonomical facts from a parade of guests. For instance: what we all get wrong about Darwin; what an iPod has in common with the “hell ant”; and how a “memory athlete” memorizes a deck of cards. Mike Maughan is our real-time fact-checker.

In the early 20th century, Max Weber argued that Protestantism created wealth. Finally, there are data to prove if he was right. All it took were some missionary experiments in the Philippines and a clever map-matching trick that goes back to 16th-century Germany.

The quirky little grocery chain with California roots and German ownership has a lot to teach all of us about choice architecture, efficiency, frugality, collaboration, and team spirit.

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 F.D.A. commissioner — and the organizers of Milktoberfest.

It began as a post-war dream for a more collaborative and egalitarian workplace. It has evolved into a nightmare of noise and discomfort. Can the open office be saved, or should we all just be working from home?

The Ford Motor Company is ditching its legacy sedans, doubling down on trucks, and trying to steer its stock price out of a long skid. But C.E.O. Jim Hackett has even bigger plans: to turn a century-old automaker into the nucleus of a “transportation operating system.” Is Hackett just whistling past the graveyard, or does he see what others can’t?

We all know our political system is “broken” — but what if that’s not true? Some say the Republicans and Democrats constitute a wildly successful industry that has colluded to kill off competition, stifle reform, and drive the country apart. So what are you going to do about it?

A conversation with the iconic singer-songwriter, recorded for the Freakonomics Radio series “How to Be Creative.”

Family environments and “diversifying experiences” (including the early death of a parent); intrinsic versus extrinsic motivations; schools that value assessments, but don't assess the things we value. All these elements factor into the long, mysterious march towards a creative life. To learn more, we examine the early years of Ai Weiwei, Rosanne Cash, Elvis Costello, Maira Kalman, Wynton Marsalis, Jennifer Egan, and others. (Ep. 2 of the “How to Be Creative” series.)

A conversation with veteran NBA point guard Jeremy Lin, recorded for the Freakonomics Radio series “The Hidden Side of Sports.”

There are thousands of books on the subject, but what do we actually know about creativity? In this new series, we talk to the researchers who study it as well as artists, inventors, and pathbreakers who live it every day: Ai Weiwei, James Dyson, Elvis Costello, Jennifer Egan, Rosanne Cash, Wynton Marsalis, Maira Kalman, and more. (Ep. 1 of the “How to Be Creative” series.)

You said, “I’m sorry,” but somehow you haven’t been forgiven. Why? Because you’re doing it wrong! A report from the front lines of apology science.

The World Trade Organization is the referee for 164 trading partners, each with their own political and economic agendas. Lately, those agendas have gotten more complicated — especially with President Trump’s tariff blitz. Roberto Azevêdo, head of the W.T.O., tells us why it’s so hard to balance protectionism and globalism; what’s really behind the loss of jobs; and what he’d say to Trump (if he ever gets the chance).

A conversation with 2008 Olympic gold medalist Shawn Johnson, recorded for the Freakonomics Radio series “The Hidden Side of Sports.”

There are a lot of factors that go into greatness, many of which are not obvious. A variety of Olympic and professional athletes tell us how they made it and what they sacrificed to get there. And if you can identify the sport most likely to get a kid into a top college — well then, touché! (Ep. 3 of “The Hidden Side of Sports” series.)

Stephen Dubner’s conversations with members of the San Francisco 49ers offense, recorded for Freakonomics Radio episode No. 350, part of the “Hidden Side of Sports” series.

The San Francisco 49ers, one of the most valuable sports franchises in the world, also used to be one of the best. But they’ve been losing lately — a lot — and one of their players launched a controversy by taking a knee during the national anthem. So why is everyone there so optimistic? To find out, we speak with the team’s owner, head coach, general manager, and star players, including their new $137.5 million quarterback. (Ep. 2 of “The Hidden Side of Sports” series.)

Dollar-wise, the sports industry is surprisingly small, about the same size as the cardboard-box industry. So why does it make so much noise? Because it reflects — and often amplifies — just about every political, economic, and social issue of the day. Introducing a new series, “The Hidden Side of Sports.”

We all know the standard story: our economy would be more dynamic if only the government would get out of the way. The economist Mariana Mazzucato says we’ve got that story backward. She argues that the government, by funding so much early-stage research, is hugely responsible for big successes in tech, pharma, energy, and more. But the government also does a terrible job in claiming credit — and, more important, getting a return on its investment.

Kenji Lopez-Alt became a rock star of the food world by bringing science into the kitchen in a way that everyday cooks can appreciate. Then he dared to start his own restaurant — and discovered problems that even science can’t solve.

The environmentalists say we’re doomed if we don’t drastically reduce consumption. The technologists say that human ingenuity can solve just about any problem. A debate that’s been around for decades has become a shouting match. Is anyone right?

The U.N.’s World Happiness Report — created to curtail our unhealthy obsession with G.D.P. — is dominated every year by the Nordic countries. We head to Denmark to learn the secrets of this happiness epidemic (and to see if we should steal them).

After every mass shooting or terrorist attack, victims and survivors receive a huge outpouring of support — including a massive pool of compensation money. How should that money be allocated? We speak with the man who’s done that job after many tragedies, including 9/11. The hard part, it turns out, isn’t attaching a dollar figure to each victim; the hard part is acknowledging that dollars can’t heal the pain.

One of the world’s biggest and best-known companies just announced that its C.E.O. would be stepping down in the fall. We interviewed her as part of our series “The Secret Life of a C.E.O.," and we thought you might like to hear that episode again, or for the first time if you missed it back then.

In this live episode of “Tell Me Something I Don’t Know,” we learn why New York has skinny skyscrapers, how to weaponize water, and what astronauts talk about in space. Joining Stephen J. Dubner as co-host is the linguist John McWhorter; Bari Weiss (The New York Times) is the real-time fact-checker.

He was once the most lionized athlete on the planet, with seven straight Tour de France wins and a victory over cancer too. Then the doping charges caught up with him. When he finally confessed to Oprah, he admits, “it didn’t go well at all.” That’s because he wasn’t actually contrite yet. Now, five years later, he says he is. Do you believe him?

It happens to just about everyone, whether you’re going for Olympic gold or giving a wedding toast. We hear from psychologists, economists, and the golfer who some say committed the greatest choke of all time.

You wouldn’t think you could win a Nobel Prize for showing that humans tend to make irrational decisions. But that’s what Richard Thaler has done. The founder of behavioral economics describes his unlikely route to success; his reputation for being lazy; and his efforts to fix the world — one nudge at a time.

After 8 years and more than 300 episodes, it was time to either 1) quit, or 2) make the show bigger and better. We voted for number 2. Here’s a peek behind the curtain and a preview of what you’ll be hearing next.

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?

For soccer fans, it's easy. For the rest of us? Not so much, especially since the U.S. team didn't qualify. So here's what to watch for even if you have no team to root for. Because the World Cup isn't just a gargantuan sporting evént; it's a microcosm of human foibles and (yep) economic theory brought to life.

We are in the midst of a historic (and wholly unpredicted) rise in urbanization. But it's hard to retrofit old cities for the 21st century. Enter Dan Doctoroff. The man who helped modernize New York City — and tried to bring the Olympics there — is now C.E.O. of a Google-funded startup that is building, from scratch, the city of the future.

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?

Pharmaceutical firms donate an enormous amount of their products (and some cash too). But it doesn't seem to be helping their reputation. We ask Pfizer's generosity chief why the company gives so much, who it really helps, and whether all this philanthropy is just corporate whitewashing.

Corporate Social Responsibility programs can attract better job applicants who'll work for less money. But they also encourage employees to misbehave. Don't laugh — you too probably engage in “moral licensing,” even if you don't know it.

We all like to throw around terms that describe human behavior — “bystander apathy” and “steep learning curve” and “hard-wired.” Most of the time, they don't actually mean what we think they mean. But don't worry — the experts are getting it wrong, too.

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. So what happens next?

Sure, medical progress has been astounding. But today the U.S. spends more on healthcare than any other country, with so-so outcomes. Atul Gawande — cancer surgeon, public-health researcher, and best-selling author — has some simple ideas for treating a painfully complex system.

Three former White House economists weigh in on the new tax bill. A sample: "The overwhelming evidence is that the trickle-down, magic-beanstalk beans argument — that's just nonsense."

Kevin Hassett, chairman of the Council of Economic Advisers, explains the thinking behind the controversial new Republican tax package — and why its critics are wrong. (Next week, we'll hear from the critics.)

Stephen Dubner's conversation with the founder and longtime C.E.O. of Bridgewater Associates, recorded for the Freakonomics Radio series “The Secret Life of a C.E.O.”

Humans, it has long been thought, are the only animal to engage in economic activity. But what if we've had it exactly backward?

Stephen Dubner's conversation with the Facebook founder and C.E.O., recorded for the Freakonomics Radio series “The Secret Life of a C.E.O.”

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.

Stephen Dubner's conversation with the former C.E.O. of Yahoo, recorded for the Freakonomics Radio series “The Secret Life of a C.E.O.”

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.

Stephen Dubner's conversation with the former longtime C.E.O. of General Electric, recorded for the Freakonomics Radio series “The Secret Life of a C.E.O.”

Every 12 years, there's a spike in births among certain communities across the globe, including the U.S. Why? Because the Year of the Dragon, according to Chinese folk belief, confers power, fortune, and more. We look at what happens to Dragon babies when they grow up, and why timing your kid's birth based on the zodiac isn't as ridiculous it sounds.

Stephen Dubner's conversation with the C.E.O. of Microsoft, recorded for the Freakonomics Radio series “The Secret Life of a C.E.O.”

Whether it's a giant infrastructure plan or a humble kitchen renovation, it'll inevitably take way too long and cost way too much. That's because you suffer from “the planning fallacy.” (You also have an “optimism bias” and a bad case of overconfidence.) But don't worry: we've got the solution.

Stephen Dubner's conversation with the co-founder and longtime co-C.E.O. of the Carlyle Group, recorded for the Freakonomics Radio series “The Secret Life of a C.E.O.”

In our collective zeal to reform schools and close the achievement gap, we may have lost sight of where most learning really happens — at home.

Stephen Dubner's conversation with the Virgin Group founder, recorded for the Freakonomics Radio series “The Secret Life of a C.E.O.”

If you're a C.E.O., there are a lot of ways to leave your job, from abrupt firing to carefully planned succession (which may still go spectacularly wrong). In this final episode of our "Secret Life of a C.E.O." series, we hear those stories and many more. Also: what happens when you no longer have a corner office to go to — and how will you spend all that money?​

Only 5 percent of Fortune 500 companies are run by women. Why? Research shows that female executives are more likely to be put in charge of firms that are already in crisis. Are they being set up to fail? (Part 5 of a special series, "The Secret Life of C.E.O.'s.")

No, it's not your fault the economy crashed. Or that consumer preferences changed. Or that new technologies have blown apart your business model. But if you're the C.E.O., it is your problem. So what are you going to do about it? First-hand stories of disaster (and triumph) from Mark Zuckerberg, Steve Ballmer, Satya Nadella, Jack Welch, Ellen Pao, Richard Branson, and more. (Part 4 of a special series, "The Secret Life of C.E.O.'s.")

The gig economy offers the ultimate flexibility to set your own hours. That's why economists thought it would help eliminate the gender pay gap. A new study, using data from over a million Uber drivers, finds the story isn't so simple.

We assembled a panel of smart dudes -- a two-time Super Bowl champ; a couple of N.F.L. 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.

Indra Nooyi became C.E.O. of PepsiCo just in time for a global financial meltdown. She also had a portfolio full of junk food just as the world decided that junk food is borderline toxic. Here's the story of how she overhauled that portfolio, stared down activist investors, and learned to "leave the crown in the garage." (Part 3 of a special series, "The Secret Life of C.E.O.'s")

Mark Zuckerberg's dentist dad was an early adopter of digital x-rays. Jack Welch blew the roof off a factory. Carol Bartz was a Wisconsin farm girl who got into computers. No two C.E.O.'s have the same origin story — so we tell them all! How the leaders of Facebook, G.E., Yahoo!, PepsiCo, Microsoft, Virgin, the Carlyle Group, Reddit, and Bridgewater Associates made it to the top. (Part 2 of a special series, "The Secret Life of C.E.O.'s.")

They're paid a fortune — but for what, exactly? What makes a good C.E.O. — and how can you even tell? Is "leadership science" a real thing — or just airport-bookstore mumbo jumbo? We put these questions to Mark Zuckerberg, Richard Branson, Indra Nooyi, Satya Nadella, Jack Welch, Ray Dalio, Carol Bartz, David Rubenstein, and Ellen Pao. (Part 1 of a special series, "The Secret Life of C.E.O.'s.")

Gina Raimondo, the governor of tiny Rhode Island, has taken on unions, boosted big business, and made friends with Republicans. She is also one of just 15 Democratic governors in the country. Would there be more of them if there were more like her?

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?

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?

Sure, markets generally work well. But for some transactions — like school admissions and organ transplants — money alone can't solve the problem. That's when you need a market-design wizard like Al Roth.

The International Monetary Fund has long been the "lender of last resort" for economies in crisis. Christine Lagarde, who runs the institution, would like to prevent those crises from ever happening. She tells us her plans.

The public has almost no chance to buy good tickets to the best events. Ticket brokers, meanwhile, make huge profits on the secondary markets. Here's the story of how this market got so dysfunctional, how it can be fixed – and why it probably won't be.

Economists have a hard time explaining why productivity growth has been shrinking. One theory: true innovation has gotten much harder – and much more expensive. So what should we do next?

Most people don't enjoy the simple, boring act of putting money in a savings account. But we do love to play the lottery. So what if you combine the two, creating a new kind of savings account with a lottery payout?

They are the most-trusted profession in America (and with good reason). They are critical to patient outcomes (especially in primary care). Could the growing army of nurse practitioners be an answer to the doctor shortage? The data say yes but —  big surprise — doctors' associations say no.

Dubner and his Freakonomics co-author Steve Levitt answer your questions about crime, traffic, real-estate agents, the Ph.D. glut, and how to not get eaten by a bear.

In this live episode of "Tell Me Something I Don't Know," you'll learn about carcass balancing, teen sleeping, and brand naming. Joining Stephen J. Dubner as co-host is Alex Wagner (CBS This Morning Saturday); author A.J. Jacobs (It's All Relative) is the live fact-checker.

Corporations and rich people donate billions to their favorite think tanks and foundations. Should we be grateful for their generosity — or suspicious of their motives?

Academic studies are nice, and so are Nobel Prizes. But to truly prove the value of a new idea, you have to unleash it to the masses. That's what a dream team of social scientists is doing — and we sat in as they drew up their game plan.

Celiac disease is thought to affect roughly one percent of the population. The good news: it can be treated by quitting gluten. The bad news: many celiac patients haven't been diagnosed. The weird news: millions of people without celiac disease have quit gluten – which may be a big mistake.

Smart government policies, good industrial relations, and high-end products have helped German manufacturing beat back the threats of globalization.

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. So what happens next?

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.

The gist: we spend billions on end-of-life healthcare that doesn’t do much good. So what if a patient could forego the standard treatment and get a cash rebate instead?

The comedian, actor -- and now, author -- answers our FREAK-quently Asked Questions.

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?

We seem to have decided that ethnic food tastes better when it's served by people of that ethnicity (or at least something close). Does this make sense -- and is it legal?

We Americans may love our democracy -- at least in theory -- but at the moment our feelings toward the federal government lie somewhere between disdain and hatred. Which electoral and political ideas should be killed off to make way for a saner system?

Overt discrimination in the labor markets may be on the wane, but women are still subtly penalized by all sorts of societal conventions. How can those penalties be removed without burning down the house?

It's a remarkable ecosystem that allows each of us to exercise control over our lives. But how much control do we truly have? How many of our decisions are really being made by Google and Facebook and Apple? And, perhaps most importantly: is the Internet's true potential being squandered?

Eric Garcetti, the mayor of Los Angeles, has big ambitions but knows he must first master the small stuff. He's also a polymath who relies heavily on data and new technologies. Could this be what modern politics is supposed to look like?

There are more than twice as many suicides as murders in the U.S., but suicide attracts far less scrutiny. Freakonomics Radio digs through the numbers and finds all kinds of surprises.

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.

There are all kinds of civics-class answers to that question. But how true are they? Could it be that we like to read about war, politics, and miscellaneous heartbreak simply because it's (gasp) entertaining?

Public bathrooms are noisy, poorly designed, and often nonexistent. What to do?

You've seen them — everywhere! — and often clustered together, as if central planners across America decided that what every city really needs is a Mattress District. There are now dozens of online rivals too. Why are there so many stores selling something we buy so rarely?

Patrick Smith, the author of Cockpit Confidential, answers every question we can throw at him about what really happens up in the air. Just don't get him started on pilotless planes -- or whether the autopilot is actually doing the flying.

When the uncelebrated Leicester City Football Club won the English Premier League, it wasn't just the biggest underdog story in recent history. It was a sign of changing economics — and that other impossible, wonderful events might be lurking just around the corner.

Our Self-Improvement Month concludes with a man whose entire life and career are one big pile of self-improvement. Nutrition? Check. Bizarre physical activities? Check. Working less and earning more? Check. Tim Ferriss, creator of the Four-Hour universe, may at first glance look like a charlatan, but it seems more likely that he's a wizard -- and the kind of self-improvement ally we all want on our side.

Games are as old as civilization itself, and some people think they have huge social value regardless of whether you win or lose. Tom Whipple is not one of those people. That's why he consulted an army of preposterously overqualified experts to find the secret to winning any game.

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.

"Books are a pain in the ass," says Gladwell, who has written some of the most popular, influential, and beloved non-fiction books in recent history. In this wide-ranging and candid conversation, he describes other pains in the ass -- as well as his passions, his limits, and why he'll never take up golf.

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.

It's Self-Improvement Month at Freakonomics Radio. We begin with a topic that seems to be on everyone's mind: how to get more done in less time. First, however, a warning: there's a big difference between being busy and being productive.

A lot of full-time jobs in the modern economy simply don't pay a living wage. And even those jobs may be obliterated by new technologies. What's to be done so that financially vulnerable people aren't just crushed? It may finally be time for an idea that economists have promoted for decades.

Critics -- including President Obama -- say short-term, high-interest loans are predatory, trapping borrowers in a cycle of debt. But some economists see them as a useful financial instrument for people who need them. As the Consumer Financial Protection Bureau promotes new regulation, we ask: who's right?

People who sleep better earn more money. Now all we have to do is teach everyone to sleep better.

Could a lack of sleep help explain why some people get much sicker than others?

As sexy as the digital revolution may be, it can't compare to the Second Industrial Revolution (electricity! the gas engine! antibiotics!), which created the biggest standard-of-living boost in U.S. history. The only problem, argues the economist Robert Gordon, is that the Second Industrial Revolution was a one-time event. So what happens next?

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.

The junior U.S. Senator from New Jersey thinks bipartisanship is right around the corner. Is he just an idealistic newbie or does he see a way forward that everyone else has missed?

Now and again, Freakonomics Radio puts hat in hand and asks listeners to donate to the public-radio station that produces the show. Why on earth should anyone pay good money for something that can be had for free? Here are a few reasons.

A famous economics essay features a pencil (yes, a pencil) arguing that “not a single person on the face of this earth knows how to make me.” Is the pencil just bragging? In any case, what can the pencil teach us about our global interdependence — and the proper role of government in the economy?

The digital age is making pen and paper seem obsolete. But what are we giving up if we give up on handwriting?

Okay, maybe the steps aren't so easy. But a program run out of a Toronto housing project has had great success in turning around kids who were headed for trouble.

If U.S. schoolteachers are indeed "just a little bit below average," it's not really their fault. So what should be done about it?

The Montgomery Bus Boycott, the South African divestment campaign, Chick-fil-A! Almost anyone can launch a boycott, and the media loves to cover them. But do boycotts actually produce the change they're fighting for?

Experts and pundits are notoriously bad at forecasting, in part because they aren't punished for bad predictions. Also, they tend to be deeply unscientific. The psychologist Philip Tetlock is finally turning prediction into a science -- and now even you could become a superforecaster.

Discrimination can't explain why women earn so much less than men. If only it were that easy.

Sure, we all want to make good personal decisions, but it doesn't always work out. That's where "temptation bundling" comes in.

A team of economists has been running the numbers on the U.N.'s development goals. They have a different view of how those billions of dollars should be spent.

The argument for open borders is compelling -- and deeply problematic.

One woman's quest to find the best burger in town can teach all of us to eat smarter.

He was handed the keys to the global economy just as it started heading off a cliff. Fortunately, he'd seen this movie before.

Even a brutal natural disaster doesn't diminish our appetite for procreating. This surely means we're heading toward massive overpopulation, right? Probably not.

In our collective zeal to reform schools and close the achievement gap, we may have lost sight of where most learning really happens -- at home.

Lessons from Tom Petty's rise and another rocker's fall.

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.

Researchers are trying to figure out who gets bored - and why - and what it means for ourselves and the economy. But maybe there's an upside to boredom?

Doctors, chefs, and other experts are much more likely than the rest of us to buy store-brand products. What do they know that we don't?

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

When one athlete turned pro, his mom asked him for $1 million. Our modern sensibilities tell us she doesn't have a case. But should she?

Anne-Marie Slaughter was best known for her adamant views on Syria when she accidentally became a poster girl for modern feminism. As it turns out, she can be pretty adamant in that realm as well.

Suspenders may work better, but the dork factor is too high. How did an organ-squeezing belly tourniquet become part of our everyday wardrobe -- and what other suboptimal solutions do we routinely put up with?

From domestic abusers to former child soldiers, there is increasing evidence that behavioral therapy can turn them around.

Conventional programs tend to be expensive, onerous, and ineffective. Could something as simple (and cheap) as cognitive behavioral therapy do the trick?

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

We spend billions on end-of-life healthcare that doesn't do much good. So what if a patient could forego the standard treatment and get a cash rebate instead?

Step 1: Hire a Harvard psych professor as the pitchman. Step 2: Have him help write the script ...

What do NASCAR drivers, Glenn Beck and the hit men of the NFL have in common?

There are all kinds of civics-class answers to that question. But how true are they? Could it be that we like to read about war, politics, and miscellaneous heartbreak simply because it's (gasp) entertaining?

Why is soccer the best sport? How has Harlan Coben sold 70 million books? And why does "Apollo 13" keep you enthralled even when you know the ending?

The comedian, actor -- and now, author -- answers our FREAK-quently Asked Questions
