What makes a good life? For decades, psychologists have debated whether true fulfillment comes from happiness—a life of comfort and joy—or meaning—a life of purpose and impact. But what if there's a third way?

University of Chicago psychology professor Shigehiro Oishi has spent his career studying happiness, meaning, and what truly brings people deep satisfaction. His new research suggests that some of the most fulfilled people don’t prioritize either—they live psychologically rich lives, full of novelty, challenges, and transformative experiences. In this episode, Oishi explains why psychological richness might be the missing piece in our search for fulfillment.

What if the secret to restoring your focus, improving your mental health, and even reducing crime rates wasn’t found in an app or a pill, but in a tree? In this episode, we speak with University of Chicago psychologist Marc Berman, whose research on “soft fascination” and nature’s cognitive effects is reshaping how we think about everything from urban planning to depression treatment. From groundbreaking hospital studies to surprising results with plastic plants, Berman’s work uncovers the deep—and often invisible—power that natural environments hold over our minds and bodies. Whether you're a city planner, a parent, or just someone feeling mentally fatigued, this conversation may just change the way you think about a walk in the park.

As AI rapidly changes how we work, learn, and communicate, it also raises an urgent question: What does it mean to grow up in a world dominated by smart technology? From smart-baby monitors to stuffed animals embedded with LLMs, kids and parents are increasingly bombarded with AI everywhere they turn.

According to Prof. Dana Suskind, a renowned surgeon and pediatrician at the University of Chicago, AI might be able to mimic language, logic, and creativity, but it cannot replace the deeply relational, responsive human interactions that are crucial to a child’s development. In her latest book, Human Raised: Nurturing Connection, Curiosity & Lifelong Learning in the Age of AI, Suskind argues that the earliest years of life are more critical than ever—and that parents and caregivers cannot be replaced or outsourced in building a child's brain.

Suskind explains how we can build a society that genuinely supports parents in raising the next generation, so that human connection does not become a “luxury good."

Every day, we throw things away, only to be forgotten forever. But society didn’t always work in the same way. In this episode, we speak with University of Chicago scholar and anthropologist Sarah Newman to discuss her book, Unmaking Waste: New Histories of Old Things.

An archaeologist by training, Newman discusses the history of trash across time—from the ancient Mayan civilization through today’s disposable culture. She argues that other societies valued objects much more deeply, reusing and recycling items in innovative ways. But will we ever return to this kind of zero-waste mentality? Newman argues that true sustainability requires a radical, systemic overhaul of how products are designed, valued and dismantled. She challenges us to look beyond the recycling bin and imagine a world where waste isn't just managed, but systematically unmade if we are to genuinely rethink our relationship with garbage and reshape our future.

Why does it seem so difficult to cancel an online subscription, delete an account, or opt out of data tracking? You might think it’s just bad luck or a confusing online interface, but more often than not, it’s by design.

In this episode of Big Brains, we speak with Marshini Chetty, Professor in the University of Chicago’s Department of Computer Science. As a leading expert in human-computer interaction, Chetty reveals the science behind "dark patterns” online—the subtle, manipulative design choices woven into the apps and websites we use every day. We explore how these deceptive interfaces weaponize human psychology to keep us clicking, spending and sharing our data.
