Reasonably Optimistic

The Democratic Socialists of America was once on the fringes of American politics. Now, DSA candidates are winning primaries, challenging establishment Democrats and pushing the Democratic Party leftward on everything from housing and health care to policing and Israel. But can the movement turn that energy into lasting political power?

Host Megan McArdle is joined by David Weigel, a national politics reporter at Semafor, to discuss...

On platforms like Kalshi and Polymarket, users can bet on elections, interest-rate cuts, corporate earnings and almost any question with an answer that will eventually be revealed. Those bets can produce a different kind of forecast than a traditional poll. But what happens when betting on everything becomes easier and more socially acceptable?

Host Megan McArdle is joined by Robin Hanson, an economist at George Mason University and...

The polls suggest a strong Democratic showing in the 2026 midterms. They also reveal an electorate angry about the cost of living, political corruption and a system many believe is rigged against them. But what will that anger mean at the ballot box?

Host Megan McArdle is joined by Kristen Soltis Anderson, a pollster and co-founder of Echelon Insights. They break down what the polls are telling us, whether Democrats are headed for a...

The American Dream can feel farther away than ever. Housing is expensive, good jobs seem harder to find and the people getting rich seem to be concentrated in a handful of big cities. But some of America’s biggest fortunes are being built far from the spotlight: by auto dealers, contractors, beverage distributors and the owners of the unglamorous businesses that keep everyday life running. So who are these overlooked milliona...

There’s a lot to complain about in the American political system: Congress lurches from deadline to deadline, presidents claim more and more power and each side of the aisle treats the other as an existential threat. So how did our political system get this way—and what would it take to make it work again?

Host Megan McArdle is joined by Yuval Levin, director of Social, Cultural, and Constitutional Studies at the America...

A viral debate over bringing iced coffee to a job interview may seem trivial. But it points to a bigger divide over what employers are looking for when college degrees, cover letters and résumés reveal less than they used to.

Host Megan McArdle explains why workplace norms still matter, why an interview can be one of the few ways applicants can stand out and what Gen Z workers miss when they begin their careers remotely. She also ma...

Artificial intelligence feels different from previous technological innovations because it can write, reason, analyze and generate ideas. In other words, it can do at least some of the things many white-collar workers thought made them irreplaceable. So, is AI going to eliminate jobs or transform them? And what will it do to the culture of the workplace — and to the way younger workers develop the judgment and expertise they ...

What do you do when your research leads to a conclusion that challenges conventional wisdom? You can publish it and risk the backlash — or quietly bury the findings and move on to safer work. The Carob Trust Prize, a new $1 million award, aims to change that calculation by rewarding academics whose research challenges prevailing orthodoxies and withstands scrutiny. But can money really make telling the truth less costly?

In the decades following World War II, the American right coalesced around fusionism — the idea that individual liberty and limited government could coexist with religious faith and traditional morality. Today, that coalition is divided. After a decade of Trump-era politics, can fusionism bring it back together?

Host Megan McArdle is joined by Stephanie Slade, senior editor at Reason magazine and author of “Fusionism: Li...

No one likes the idea of being surveilled. That concern is fueling a nationwide backlash against Flock cameras, the automated license plate readers police use to find stolen vehicles, track suspects and locate missing people. Critics see their rapid spread as the beginnings of a mass surveillance network. Supporters say they reduce crime and save lives. So can communities keep the benefits without sacrificing privacy?

Host Megan McA...

Artificial intelligence is advancing faster than many expected. So much so that some of the experts who understand it best are sounding the alarm. Are their warnings exaggerated, or are we approaching a point of no return? And what can we do now to shape the future of artificial intelligence?

Host Megan McArdle is joined by Tim Lee, author of the Understanding AI newsletter, to explore what AI experts fear most, from misinformation ...

More than six centuries ago, the Black Death wiped out nearly half of England’s population. Suddenly, workers had more power, wealthy landowners had less, and the old social order began to crack. When the ruling class tried to force that order back into place, anger erupted into the Peasants’ Revolt of 1381 — a political crisis that feels startlingly familiar today, dramatized in the new film “The Uprising.&...

It doesn’t take much to ignite a new wave of alien conspiracy theories on social media. But beyond the internet speculation lies a serious scientific question: If billions of planets could support life, why haven’t we found any?

Host Megan McArdle revisits her conversation with astrophysicist and author of “The Little Book of Aliens,” Adam Frank, to explore why he thinks extraterrestrial life probably exists ...

Shortly before her mother died, Megan McArdle learned a family secret. Decades earlier, her mother had given birth to a son and placed him for adoption. Megan’s attempt to find the brother she never knew would force her to reconsider her mother’s life—and confront abortion as something more than an abstract political debate.

In this deeply personal episode, producer Regina de Heer interviews Megan about the choices...

AI data centers have become America’s newest political villain — accused of draining local water supplies, overheating communities and sending electricity bills soaring. But some of the most alarming claims about their environmental impact are based on outdated estimates, missing context or questionable math.

Host Megan McArdle is joined by writer and former high school physics teacher Andy Masley to separate the myths f...

Football season is back, bringing millions of Americans together around one of the country’s most beloved sports. But new research on chronic traumatic encephalopathy, or CTE, raises an uncomfortable question: What price are players paying for our entertainment?

Host Megan McArdle explores the physical and cognitive toll of football and what responsibility fans have when they turn on a game.

Why are Americans having fewer children, even though many say they want larger families? Host Megan McArdle talks with author Tim Carney about how professional ambition, personal autonomy and intensive parenting have made family life more daunting. They discuss why Americans are marrying later, how workplaces and communities could make raising children easier, and whether stronger family norms can be revived without bringing back t...

The controversy surrounding Cambridge professor Jason Arday began with questions about his academic record and extraordinary personal story. It ended in tragedy. What can sociology tell us about how a scandal like this escalates once it's forced into public view?

Host Megan McArdle talks with UCLA sociologist Gabriel Rossman about scandal, status and public shaming.

America is becoming less religious — but the story is more complicated than empty pews. Host Megan McArdle is joined by political scientist and former pastor Ryan Burge to talk about the shifts taking place in America's churches. Are congregations shrinking or growing? Why are some religious traditions holding on better than others? And what does the rise of the religiously unaffiliated mean for American life?
