The Michael Shermer Show

The Truth About Sex Differences (Steve Stewart-Williams)

How do men and women differ? Where do the differences come from? And how do they shape modern life? Drawing on a century of research and a billion years of evolution, Steve Stewart-Williams explains why many sex differences appear despite socialization, not because of it; why in our mating and parenting patterns, humans are more like the average bird than the average mammal; and why sex differences are sometimes a sign of societal health rather than injustice. Steve Stewart-Williams is a professor of psychology at the University of Nottingham Malaysia. His first book, Darwin, God, and the Meaning of Life, was published in 2010. His second, The Ape That Understood the Universe, was published in 2018. His new book is A Billion Years of Sex Differences.

America at 250: What Did the Founders Get Right?

Michael Shermer makes the case that the U.S. Founding Fathers were not only steeped in Enlightenment values on which the Declaration of Independence was based, but they were also scientists searching to discover moral truths and values on which to base a rational society, which they succeeded in doing in this document along with the Constitution.

When History Goes on Trial: Demjanjuk, Eichmann, and Justice After Atrocity

John Demjanjuk lived for decades as a retired autoworker in suburban Cleveland. Then investigators accused him of being "Ivan the Terrible," one of the most notorious guards at Treblinka. What followed was one of the strangest and most troubling Nazi war-crimes cases of the postwar era: extradition, eyewitness testimony, a death sentence, a reversal, and a final prosecution many years later. In this episode, Michael Shermer talks with Lawrence Douglas, professor at Amherst College and author of The Criminal State: War Atrocity and the Dream of International Justice, about Demjanjuk, Eichmann, Nuremberg, Holocaust denial, and the problem of proving atrocities decades after they happened. How reliable is eyewitness memory after 40 or 50 years? What did Nuremberg actually establish? Was Eichmann really just a bureaucrat? And can a courtroom ever deliver justice for crimes almost too large to comprehend? Lawrence Douglas is the James J. Grosfeld Professor of Law, Jurisprudence, and Social Thought at Amherst College and a Guggenheim fellow. His many books include The Right Wrong Man and The Memory of Judgment. His writing has appeared in leading publications such as Harper's, The Wall Street Journal, and The Economist. His new book is The Criminal State: War Atrocity and the Dream of International Justice.

Why I Joined the Government UAP Science Advisory Council

Massimo Pigliucci on Doubt, Moral Courage, and Living Without Illusions

What does it mean to live well when certainty is unavailable? Michael Shermer speaks with Massimo Pigliucci about moral character, ancient philosophy, and the difficult art of making decisions without easy answers. The conversation moves from Cicero and Stoicism to the legacy of the New Atheism, asking why rejecting religion is not the same as having a philosophy of life. They discuss virtue ethics, moral dilemmas, effective altruism, faith, free will, democracy, human flourishing, and the uneasy relationship between facts and values. From the trolley problem and Peter Singer's drowning child thought experiment to the ethics of charity, the limits of utilitarian thinking, and the dangers of tribalism, this episode asks how we should act when rules fail, consequences are uncertain, and good intentions are not enough. Massimo Pigliucci is a bestselling author, philosopher, evolutionary biologist, and the K.D. Irani Professor of Philosophy at the City College of New York. His work spans evolutionary biology, philosophy of science, pseudoscience, and practical philosophy. His latest book is How to Be a Happy Skeptic: The Power of Doubt in a Meaningful Life.
