What shapes us more: our DNA or the way we’re raised? The “nature” camp points to genetic research and studies of twins raised apart, arguing that traits from personality to abilities are strongly influenced by inherited biology, limiting how much parenting can shape who children become. The “nurture” camp argues upbringing, culture, and parental choices profoundly influence development and behavior. So which matters more? This ethical conundrum is at the crux of this week's debate, originally broadcast in November 2019 ARGUING YES: Robert Plomin, Professor of Behavioral Genetics at King’s College London Nancy Segal, Professor of Psychology at California State University, Fullerton and Director at the Twin Studies Center ARGUING NO: Paige Harden, Psychology Professor at the University of Texas Ann Pleshette Murphy, Author & Parenting Expert Emmy award-winning journalist John Donvan moderates Recent twin studies: ⁠Parenting in Childhood Predicts Personality in Early Adulthood: A Longitudinal Twin-Differences Study⁠ (APA, 2025) ⁠Genetics of monozygotic twins reveals the impact of environmental sensitivity on psychiatric and neurodevelopmental phenotypes⁠ (Nature Human Behavior, 2025) ⁠Longitudinal associations between cognitive ability and socioeconomic status are partially genetic in Nature⁠ (Scientific Reports, 2026) Join the conversation on Substack—share your perspective on this episode and subscribe to our weekly newsletter for curated insights from our debaters, moderators, and staff.

A century after Henry Ford helped popularize the five-day, 40-hour week, could working 32 hours be next? Supporters say shorter weeks can improve well-being without sacrificing productivity, especially as AI would make workers more efficient. Others warn it would strain industries that require continuous staffing and force Americans to rethink everything from school and healthcare schedules to expectations of around-the-clock availability.

Capitalism has long been credited with driving innovation and prosperity, yet many Americans increasingly believe the system is no longer working for them.

The dangers of climate change are “no longer over the horizon.” Humanity may soon pass the “point of no return.” These are the phrases U.N. Secretary-General Antonio Guterres used to describe what he called an “utterly inadequate” global response to rising temperatures. But if we were to decisively act and restructure our global economy with the climate in mind, who would shoulder the burden? Or should our collective focus orient more toward humans’ capacity for adaptation? This ethical conundrum is at the crux of this week's debate, originally broadcast in July 2022. Arguing Yes: Bjorn Lomborg, Author of the Bestsellers "Cool It" and "The Skeptical Environmentalist"; Director of the Copenhagen Consensus Center Matthew Kahn, Provost Professor of Economics and Spatial Sciences at the University of Southern California Arguing No: Michele Wucker, Economic Policy Expert & Founder of Gray Rhino & Company Kaveh Madani, Environmental Scientist; Former Vice President of the United Nations Environment Assembly Bureau; Former Deputy Head of Iran’s Department of Environment Emmy award-winning journalist John Donvan moderates Join the conversation on Substack—share your perspective on this episode and subscribe to our weekly newsletter for curated insights from our debaters, moderators, and staff.

Near-death experiences have long challenged our understanding of consciousness and mortality. Some who come close to death report leaving their bodies, encountering vivid visions, or feeling profound peace. Are these experiences evidence that consciousness can survive death — or can they be explained by what happens in a dying brain? This 2014 debate is one we're still thinking about today. We ask whether science can reveal what, if anything, awaits us after we die. Arguing Yes: Eben Alexander, Former Neurosurgeon; Author of "Proof of Heaven" Raymond Moody, Medical Doctor; Author of "Life After Life" Arguing No: Sean Carroll, Physicist & Writer Steven Novella, Academic Neurologist at the Yale School of Medicine Emmy award-winning journalist John Donvan moderates Join the conversation on Substack—share your perspective on this episode and subscribe to our weekly newsletter for curated insights from our debaters, moderators, and staff.

The midterms are coming up this fall, and right now we are in the middle of a contentious primary season, with a lot of new faces challenging incumbents—and many winning.

As America celebrates 250 years since the Declaration of Independence, the legacy of the Founders is under renewed scrutiny. Were they visionary architects of liberty whose achievements and creations should be celebrated, or has reverence for them sanitized the past, how we think of democracy, and the compromises embedded in the nation's founding? As the U.S. marks its semiquincentennial, we debate: Is It Time to Stop Idolizing the Founders? Arguing Yes: Osita Nwanevu, Contributing Editor at The New Republic; Columnist at The Guardian Arguing No: Helena Rosenblatt, Distinguished Professor of History, French, and Political Science, and the MA Program in Liberal Studies at the CUNY Graduate Center Emmy award-winning journalist John Donvan moderates Join the conversation on Substack—share your perspective on this episode and subscribe to our weekly newsletter for curated insights from our debaters, moderators, and staff.

Fifty years after the Supreme Court reinstated capital punishment, the death penalty remains one of America's most divisive issues. Supporters argue it delivers justice for the most heinous crimes, provides closure for victims’ families, and ensures the worst offenders can never kill again. Opponents point to wrongful convictions, racial disparities, and the moral consequences of allowing the state to take a life, arguing that life without parole is enough. Now we debate: Should the Death Penalty Be Abolished? This ethical conundrum is at the crux of this week's debate, originally broadcast in April 2015. Arguing YES: Diann Rust-Tierney, Executive Director of the National Coalition to Abolish the Death Penalty Barry Scheck, Co-Director of the Innocence Project and Professor at Cardozo Law School Arguing NO: Robert Blecker, Professor at New York Law School Kent Scheidegger, Legal Director of the Criminal Justice Legal Foundation Emmy award-winning journalist John Donvan moderates Join the conversation on Substack—share your perspective on this episode and subscribe to our weekly newsletter for curated insights from our debaters, moderators, and staff.

After signing a Memorandum of Understanding in June, the U.S. and Iran entered a delicate peace. As negotiators worked toward a permanent deal, one question loomed: Who won the war in Iran — Tehran or Trump? Hours after we concluded a debate on that very question, strikes resumed. By morning, President Trump declared the truce over. Today, we bring you that debate, and the question of who holds the upper hand, and what has been gained and lost, is more pressing than ever. Note: This debate was recorded on Tuesday, July 7, 2026, before the verbal dissolution of the Islamabad Memorandum and the resumption of military action in the Iran War. Arguing "Tehran is Winning": Suzanne Maloney, Vice President and Director of Foreign Policy at the Brookings Institution Arguing "Trump is Winning": Matthew Kroenig, Vice President for Geostrategy and Fellows and Senior Director of the Atlantic Council's Scowcroft Center for Strategy and Security Emmy award-winning journalist John Donvan moderates Join the conversation on Substack—share your perspective on this episode and subscribe to our weekly newsletter for curated insights from our debaters, moderators, and staff.
