What if the deepest human drive isn’t happiness, survival, or even love, but the need to matter?

Philosopher and MacArthur Fellow Rebecca Newberger Goldstein joins Michael Shermer to discuss The Mattering Instinct, her argument that the desire to feel significant lies at the core of human behavior. That drive helps explain our greatest achievements, from creativity and moral courage to scientific and artistic excellence. It also helps explain some of our darkest outcomes, including extremism, violence, and ideological fanaticism.

Goldstein examines why people will give up comfort, status, and sometimes even their own lives to feel that they matter. She questions why meaning cannot be captured by happiness metrics or self-help formulas, and why the same psychological force can produce saints, scientists, athletes, cult leaders, and terrorists. The conversation moves through free will, entropy, morality without God, fame, narcissism, and the crucial difference between ways of mattering that create order and those that leave damage behind.

Rebecca Newberger Goldstein is an award-winning philosopher, writer, and public intellectual. She is the author of ten books of acclaimed fiction and non-fiction, including 36 Arguments for the Existence of God: A Work of Fiction and Betraying Spinoza: The Renegade Jew Who Gave Us Modernity. She holds a PhD in philosophy of science from Princeton University and has taught at Yale, Columbia, NYU, Dartmouth, and Harvard. A fellow of the American Academy of Arts and Sciences, her work has been supported by the MacArthur “Genius” grant and fellowships from the Guggenheim, Whiting Institute, Radcliffe Institute, and the National Science Foundation. Her new book is The Mattering Instinct: How Our Deepest Longing Drives Us and Divides Us.

In this unscripted solo episode, Michael Shermer reflects on a dizzying start to the year and what it reveals about truth, power, and public judgment. From events in Venezuela and the limits of exporting democracy to a viral Planet Fitness controversy, the Minneapolis ICE shooting, and renewed claims about aliens, Shermer keeps returning to the same question: What actually helps, and what only feels like a good idea in the moment?

What if the way we approach mental health is quietly making things worse?

Psychiatrist and psychotherapist Sami Timimi joins Michael Shermer to examine some of the core assumptions behind modern psychiatry. Why have diagnoses such as ADHD, autism, anxiety, and depression expanded so dramatically—and why hasn’t increased access to treatment led to better outcomes at the population level?

Timimi describes how diagnostic categories have broadened over time and questions whether psychiatric labels function in the same way as medical diagnoses elsewhere in healthcare. Without clear biological markers, he argues, definitions can expand to include forms of distress that were once considered part of ordinary human experience.

The conversation also considers the role of meaning, identity, and culture in shaping how people understand psychological suffering. Timimi reflects on the limits of medication and therapy, the unintended consequences of the “mental illness as physical illness” model, and how social media may contribute to the spread and reinforcement of certain diagnostic categories.

Dr. Sami Timimi is a child and adolescent psychiatrist, psychotherapist, and Fellow of the Royal College of Psychiatrists. He has published more than 150 academic papers and authored or edited over a dozen books, including Naughty Boys, Liberatory Psychiatry, and The Myth of Autism. His new book is Searching for Normal: A New Approach to Understanding Mental Health, Distress, and Neurodiversity.
