The Michael Shermer Show

Why do ordinary people carry out extraordinary harm when simply told to do so? From the Holocaust to the genocides in Rwanda, Bosnia, and Cambodia, history shows how obedience to authority can lead to unimaginable acts. But what’s happening in the brain when we follow orders—even ones that conflict with our morals?

In this episode, we speak with neuroscientist Emilie Caspar, whose groundbreaking research explores how authority infl...

Amanda Knox spent nearly four years in prison and eight years on trial for a murder she didn’t commit—and became a notorious tabloid story in the process. Though she was exonerated, it’s taken more than a decade for her to reclaim her identity and truly feel free.

Albert Einstein remains renowned around the world for revolutionizing our understanding of the cosmos, but very few realize that the celebrated scientist had a deep spiritual side.

Outside of the academics and activists whose ideology came to dominate the West in the second decade of the twenty-first century, arguably no group influenced public discourse as much as the Intellectual Dark Web.

Challenging the intellectual and cultural orthodoxies that engulfed universities, the media, and big tech, this group—a loose collective of politically diverse intellectuals, commentators, and scholars critical of politic...

In all animals, mating is a deal. But few creatures behave as if sex is a simple, even mutually beneficial, transaction. Many more treat it with reverence, suspicion, angst, and violence.

Matt Ridley revisits Darwin’s revelatory theory of mate choice through the close study of the peculiar rituals of birds, and considers how this mating process complicates our own view of human evolution.

Ridley also explores the scientific researc...

In our 501st episode, Michael Shermer takes a moment to reflect on his long journey with skepticism and what he learned recording half a thousand episodes of this podcast.

Just as surgeons once believed pain was good for their patients, some argue today that death brings meaning to life. But given humans rarely live beyond a century (while certain whales can thrive for over two hundred years) it’s hard not to see our biological limits as profoundly unfair. No wonder then that most people nearing death wish they still had more time.

Yet, with ever-advancing science, will the ends of our lives always l...

In this episode, Kurt Gray offers a groundbreaking perspective on the moral mind, challenging the assumption that liberals and conservatives have radically different moral foundations.

Drawing on the latest science, he reveals that everyone’s moral judgments stem from feelings of vulnerability to harm. We all care about protecting ourselves and others, but conflict arises when we perceive harm differently. Gray explores how moral o...

In the U.S. alone, more than $400 billion are donated to charity each year—equivalent to two percent of American GDP. This generosity is wonderful, but these gifts don’t do nearly as much good as they could. In recent years, researchers have started studying the effectiveness of different charities, just as investors study the effectiveness of different companies. These researchers ask questions like: How much money does it cost fo...
