Purpose in the Eyes of a Psychiatrist

Economist Dean Spears explains the forces driving global population change, from past fears of overpopulation to today’s concerns about declining birth rates. He contrasts the perspectives of biologists and economists on population growth and highlights the role of human ideas and innovation in sustaining progress. Spears also discusses misconceptions about zero-sum economics, the links between population, health, and economic well-being, and the rise of anti-natalism. The conversation covers population size and environmental concerns, government policies on family planning, and why cultural attitudes toward reproduction may be as important as policy in addressing the challenges of a shrinking population. Dean Spears is an economist, demographer, and associate professor at the University of Texas at Austin. Spears is a founding executive director of r.i.c.e, (a research institute for compassionate economics), a nonprofit that works to promote children’s health, growth, and survival in rural India. Together with Michael Geruso, he is the author of the new book After the Spike: Population, Progress, and the Case for People.

Because brainwashing affects both the world and our observation of the world, we often don’t recognize it while it’s happening―unless we know where to look. As Rebecca Lemov writes in her new book The Instability of Truth, “Brainwashing erases itself.” What we call brainwashing is more common than we think; it is not so much what happens to other people as what can happen to anyone. In her work, Lemov exposes the myriad ways our minds can be controlled against our will, from the brainwashing techniques used against American POWs in North Korea to the “soft” brainwashing of social media doomscrolling and behavior-shaping. Rebecca Lemov is a historian of science at Harvard University and has been a visiting scholar at the Max Planck Institute. Her research explores data, technology, and the history of human and behavioral sciences. Her new book is The Instability of Truth: Brainwashing, Mind Control, and Hyper-Persuasion.

In an era of globalized education, where ideals of freedom and inquiry should thrive, an alarming trend has emerged: foreign authoritarian regimes influencing American academia. In her new book Authoritarians in the Academy, Sarah McLaughlin reveals how higher education institutions—long considered bastions of free thought—are compromising their values for financial gain and international partnerships. Her investigation uncovers the subtle yet sweeping influence of authoritarian governments, exposing university leaders who prioritize expansion and profit over the principles of free expression. She also describes incidents in which professors and administrators weighed the costs of offending repressive regimes that provide their funding. McLaughlin’s work offers a sobering look at how these compromises in academia mirror broader patterns across industries such as technology, sports, and entertainment. Sarah McLaughlin is a senior scholar of global expression at the Foundation for Individual Rights and Expression (FIRE). Her writing about free speech issues, including protest and blasphemy laws, has been featured in publications including Foreign Policy and The Huffington Post. Her new book is Authoritarians in the Academy: How the Internationalization of Higher Education and Borderless Censorship Threaten Free Speech.

In his new book Coming Clean, Eric Heinze rejects the idea that we should be less woke. In fact, we need more wokeness, but of a new kind. Yes, we must teach about classism, racism, colonialism, patriarchy, and other gross injustices, but we must also educate the public about the left’s own support for regimes that damaged and destroyed millions of lives for over a century—Stalin in the Soviet Union, Mao Zedong in China, Pol Pot in Cambodia, or the Kim dynasty in North Korea. Criticisms of Western wrongdoing are certainly important, yet Heinze explains that most on the political left have rarely engaged in the kinds of open and public self-scrutiny that they demand from others. Citing examples as different as the Ukraine war, LGBTQ+ people in Cuba, the concept of “hatred,” and the problem of leftwing antisemitism, Heinze explains why and how the left must change its memory politics if it is to claim any ethical high ground. Eric Heinze is Professor of Law and Humanities at Queen Mary University of London. He is the author of The Most Human Right: Why Free Speech is Everything (MIT Press), among other books, and has published over 100 articles and has been featured in radio and television and other media around the world. His new book is Coming Clean: The Rise of Critical Theory and the Future of the Left.

Traditional religion in the United States has suffered huge losses in recent decades. The number of Americans identifying as “not religious” has increased remarkably. Religious affiliation, service attendance, and belief in God have declined. More and more people claim to be “spiritual but not religious.” Religious organizations have been reeling from revelations of sexual and financial scandals and cover-ups. Public trust in “organized religion” has declined significantly. Crucially, these religious losses are concentrated among younger generations. This means that, barring unlikely religious revivals among youth, the losses will continue and accelerate in time, as less-religious younger Americans replace older more-religious ones and increasingly fewer American children are raised by religious parents. All this is clear. But what is less clear is exactly why this is happening. We know a lot more about the fact that traditional American religion has declined than we do about why this is so. Christian Smith is the William R. Kenan, Jr. Professor of Sociology and Founding Director of the Center for the Study of Religion and Society at the University of Notre Dame. Smith is well known for his research focused on religion, adolescents and emerging adults, and social theory. He has written many books, including Divided by Faith, Soul Searching, and Moral, Believing Animals. His new book is Why Religion Went Obsolete: The Demise of Traditional Faith in America.

In this episode, Michael Shermer speaks with historian Sophia Rosenfeld about how modern notions of personal choice—from Amazon shopping to Tinder swipes—emerged from centuries of cultural, religious, political, and economic transformation. Was there ever a time when choice wasn’t synonymous with freedom? Why were early ideas of “common sense” and “free will” so limited? And what happens when choice itself becomes overwhelming? From Enlightenment ideals to the sexual revolution and the abortion debate, Rosenfeld traces how our expanding range of options—and the meaning we attach to them—has shaped everything from our romantic lives to our political systems. A revealing look at the hidden history of freedom in a world that sometimes offers too much. Sophia Rosenfeld is Professor of History at the University of Pennsylvania. Her new book is The Age of Choice: A History of Freedom in Modern Life.
