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.

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.

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.

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.

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?

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?

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.
