The art market is so opaque and illiquid that it barely functions like a market at all. A handful of big names get all the headlines (and most of the dollars). Beneath the surface is a tangled web of dealers, curators, auction houses, speculators — and, of course, artists. In the first episode of a three-part series, we meet the key players and learn how an obscure, long-dead American painter suddenly became a superstar. (Part 1 of “The Hidden Side of the Art Market.”)

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?

You know the saying: “There are no shortcuts in life.” What if that saying is just wrong? In his new book Thinking Better: The Art of the Shortcut in Math and Life, the mathematician Marcus du Sautoy argues that shortcuts can be applied to practically anything: music, psychotherapy, even politics. Our latest installment of the Freakonomics Radio Book Club.

The U.S. is home to seven of the world’s 10 biggest companies. How did that happen? The answer may come down to two little letters: V.C. Is venture capital good for society, or does it just help the rich get richer? Stephen Dubner invests the time to find out.

A new book by an unorthodox political scientist argues that the two rivals have more in common than we’d like to admit. It’s just that most American corruption is essentially legal.

Evidence from Nazi Germany and 1940’s America (and pretty much everywhere else) shows that discrimination is incredibly costly — to the victims, of course, but also the perpetrators. One modern solution is to invoke a diversity mandate. But new research shows that’s not necessarily the answer.

 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?
