Inside the AI Debate: Hope, Hype, Or Harm? A Big Brains Panel Weighs In Jul 10, 2025

Show notes

One of the benefits of producing this podcast at the University of Chicago is that there are often events on campus that bring in not just one Big Brain, but many in order to find answers to the some of the most complex problems of our time. I recently had the pleasure of hosting one such event on artificial intelligence that we want to share with you today. It was part of the Graham School’s Leadership & Society Initiative Symposium, examined how AI could change everything and, more importantly, whether it should.

Artificial intelligence is evolving faster than most of us can keep up with—and its impact is already reshaping our lives, from the hospital to the courtroom to the art studio. Is AI moving too fast? Are we focusing on the wrong questions? And what comes after today’s generation of models? It’s a candid, complex, and eye-opening conversation you won’t want to miss.

Are Your Medications Safe And Effective?, with Jerry Avorn Jun 26, 2025

Show notes

For a more than a century, the Food and Drug Administration has worked to protect public health. In his research, Harvard University physician-researcher Jerry Avorn has examined how the FDA’s once-rigorous gold standard approval process has been affected by a powerful shortcut known as the Accelerated Approval Program—originally designed for desperate AIDS and cancer patients. He says that change in the 1990s has allowed more than half of all new drugs onto the market before drug companies have proven they actually help people.

In his new book Rethinking Medications: Truth, Power and the Drugs We Take, Avorn cites numerous examples: from a cold medicine that doesn’t de-congest to billion-dollar cancer treatments that only shrink lab results to the controversial Alzheimer’s drug Aduhelm—approved despite no clear cognitive benefits. In this episode, Avorn explores whether some prescriptions in your medicine cabinet are safe, effective and worth the money.

Are We Making AI Too Human?, with James Evans Jun 12, 2025

Show notes

Prof. James Evans, a University of Chicago sociologist and data scientist, believes we’re training AI to think too much like humans—and it’s holding science back.

In this episode, Evans shares how our current models risk narrowing scientific exploration rather than expanding it, and explains why he’s pushing for AIs that think differently from us—what he calls “cognitive aliens.” Could these “alien minds” help us unlock hidden breakthroughs? And what would it take to build them?

Inside The Disease That Changes Your Personality, with Bruce Miller May 29, 2025

Show notes

When someone we know or love starts to develop psychological issues, we don't often associate it with a form of dementia. However, this trait is one of the most common signs of frontotemporal dementia (FTD) — the most common neurodegenerative disease in people under the age of 65. In his new book, Mysteries of the Social Brain: Understanding Human Behavior Through Science, Dr. Bruce Miller highlights his experiences observing people with FTD and what they have taught him about what he calls the "social brain."

Dr. Bruce Miller has been observing people with FTD for decades in the Memory and Aging Center at the University of San Francisco, where he is also Professor of Neurology and the Founding Director of the Global Brain Health Institute. He shares key insights on how to keep our "social brain" healthy and how it can even unlock our creative potential.

Meet The ‘Planet Hunter’ Searching For Alien Life, with Jacob Bean May 15, 2025

Show notes

The search for life beyond Earth is no longer science fiction—it takes a lot of data, powerful telescopes and a bit of cosmic detective work. And at the center of this search is University of Chicago astrophysicist Jacob Bean. Bean was part of the team that made history by detecting carbon dioxide in the atmosphere of a distant planet using the James Webb Space Telescope—a major step forward in our ability to study exoplanets.

Bean uses cutting-edge tools and discoveries that are reshaping how we think about planet habitability, biosignatures and our place in the universe. From potentially habitable exoplanets like K2-18b to false hopes like Gliese 486b, Bean shares why the atmospheres of these faraway worlds might hold the key to one of humanity’s oldest questions: Are we alone in the universe?

How To Stop Gun Violence Before It Starts, with Jens Ludwig May 01, 2025

Show notes

Despite decades of policy ideas, pouring millions of dollars into the problem, and a slow pace of gun control measures, the United States hasn’t made much progress on curbing the epidemic of gun violence in our country.

For the past 25 years, Prof. Jens Ludwig of the University of Chicago has examined the questions of: Why does gun violence happen, and is there anything we can do about it?

In his new book, Unforgiving Places: The Unexpected Origins of American Gun Violence, Ludwig—who is director of the University of Chicago Crime Lab—discusses why we've been thinking about the gun violence problem in the wrong ways.

Drawing upon behavioral economics, he explains that most shootings are not premediated; rather, the result of arguments that escalate into violence. Using data-backed interventions, Ludwig introduces new ideas beyond policy and policing to get at the real root causes of gun violence today.

Can Your DNA Predict Your Future?, with Dalton Conley Apr 17, 2025

Show notes

What if a single number, derived from your DNA, could predict your income, education level or even who you're likely to marry? In his new book “The Social Genome,” Princeton University sociologist Dalton Conley explores the science behind how our genes are shaping our society in ways that are both profound and unsettling.

Conley explains how our genes, and the genes of those around us, are influencing our lives in ways we barely understand—from fertility clinics selecting embryos based on genetic traits to the rise of “genetic sorting” in everything from dating to zip codes. He also debunks the idea of nature versus nurture, revealing how deeply intertwined they truly are.

Are we heading toward a future of genetically coded inequality? And what policies and conversations are urgently needed to ensure we don’t cross the line from science into dystopia?

Can You Really Die of a Broken Heart? The Hidden Dangers of Grief, with Mary Frances O'Connor Apr 03, 2025

Show notes

When we lose someone, we love, we often say we have a broken heart—but what if that’s not just a metaphor?

In her new book “The Grieving Body: How The Stress of Loss Can Be An Opportunity For Healing” University of Arizona Professor of Psychology Mary Frances O’Connor shares groundbreaking insights into the biological and physiological impacts grief has on our bodies. O’Connor reveals how profound loss can lead to serious medical conditions, from heart attacks to immune system breakdowns, and explains why grieving can make us more vulnerable to diseases like cancer, pneumonia, and even autoimmune disorders.

Drawing on her personal experiences and extensive research, O’Connor outlines why our medical system—and society at large—needs to rethink how we support grieving individuals. She makes a powerful case for viewing grief not only as an emotional experience but as a medical event deserving careful monitoring and intervention, similar to pregnancy or chronic illness.

The Science Behind Raising Successful Kids, with Ariel Kalil Mar 20, 2025

Show notes

New federal data paints a stark picture: American children are falling behind in reading and test scores, with the gap between advantaged and disadvantaged kids growing wider. But is this really just a problem of money? University of Chicago Developmental psychologist Ariel Kalil has spent her career studying how parents influence childhood development—not just through resources, but through daily habits and interactions.

On this episode, we explore the surprising science behind parental engagement, the behavioral biases that shape parenting decisions, and why simple interventions—like 15 minutes of reading a day—can have an outsized impact. Plus, we discuss how AI and behavioral economics might provide new solutions for supporting parents in an era of rising inequality.
