How God Works: The Science Behind Spirituality

Marriage, Monogamy and the Modern Mind Mar 09, 2025

Show notes

When it comes to finding happiness, many religions see marriage as the gold standard: a path to love, stability, and fulfillment. But is that really true? And if so, why are marriage rates plummeting in so many parts of the world?

In this episode, we’ll talk to anthropologist Joseph Henrich about the surprising history of marriage and monogamy, including how these institutions helped lay the groundwork for much of our modern way of life. We’ll also speak with psychologist Geoff MacDonald about what it means to live a happy, single life in a world that often prioritizes partnership, and why marriage might not offer the best road to fulfillment for everyone.

Joseph Henrich is the Ruth Moore Professor of Human Evolutionary Biology at Harvard University, and the author of The WEIRDest People in the World: How the West Became Psychologically Peculiar and Particularly Prosperous.

Geoff MacDonald is a Professor of Psychology at the University of Toronto, where he leads the MacDonald Social Psychology Research Laboratory, which aims to study well-being in singlehood.

Every Breath You Take (From the Archive) Feb 23, 2025

Show notes

We'll be back with a whole new season of How God Works on March 9th. But in the meantime, we wanted to share shows from our archives that speak to some of the most pressing challenges we're all facing today. It’s only February, and already this has been an intense year. So if you’re feeling stressed today, how about… a breather?

It’s no accident that the Hebrew word for breath is the same as the word for spirit (ruach). Breath doesn’t just give us life: it helps regulate everything from vital organ functions to cognition and emotional states. That’s why spiritual traditions the world over incorporate it as a practice to help heal body and mind and walk the path towards peace.

Join us as we explore the breath’s connection to our nervous system with psychologist and neuroscientist Stephen Porges, creator of Polyvagal Theory. We’ll also learn about the spiritual roots of breathwork and try out a few techniques with noted yoga, qigong and meditation teacher Amelia Barili.

Learn more about Dr. Stephen Porges’s work and Polyvagal Theory on his website, and be sure to check out his new book, co-authored with Seth Porges: Our Polyvagal World: How Safety and Trauma Change Us.

Dr. Amelia Barili is faculty at the UCB Osher Lifelong Learning Institute and professor emerita from the University of California at Berkeley. Learn more about her work on her website and check out her YouTube channel the new paradigms.

We also highly recommend the book Breath: The New Science of a Lost Art, by James Nestor.

Moving Beyond Us vs Them (From the Archive) Feb 09, 2025

Show notes

We'll be back with a whole new season of How God Works starting in early March. But in the meantime, we wanted to share a few shows from our archives that speak to some of the most pressing challenges we're all facing today.

Hate and prejudice based on ethnicity, religion, gender and sexual orientation are all too common in our world. But are we doomed to be this way? Or is it possible to create a world where cooperation and peace are the norm?

Join Dave as he talks to NYU professor Jay van Bavel about the deeper mechanisms at work when it comes to group conflict (and how to avoid it), and with Zen Buddhism teacher Larry Ward about how the teachings of Thich Nhat Hanh and the Plum Village Tradition can help all of us to heal and foster a more equitable and caring world.

Jay Van Bavel is co-author (with Dominic Packer) of The Power of Us: Harnessing Our Shared Identities to Improve Performance, Increase Cooperation, and Promote Social Harmony. Find out more about Jay’s work on his website.

Larry Ward is a co-founder of The Lotus Institute and host of the podcast Beyond the News, which explores current events through the lens of Buddhism and neuroscience. He is also the author of America’s Racial Karma: An Invitation to Heal.

The gathas heard in this episode are taken from Thich Nhat Hanh’s book Peace Is Every Breath: A Practice for Our Busy Lives. Dave also makes reference to the 14 mindfulness trainings, which can be found in the book Interbeing, 4th Edition: The 14 Mindfulness Trainings of Engaged Buddhism.

Religion and Robots and AI … Oh My! (From the Archive) Jan 26, 2025

Show notes

Artificial Intelligence, and its possible applications to religion, have been in the news a lot lately, so while we're busy working on Season 8, we thought we'd share this episode from 2022 with you.

Can you pray with a robot? Will people worship AI like a god? It’s not science fiction. It’s starting to happen now. But what does it mean if robots become priests, or AIs start offering ethical advice? And how do we know when to trust them?

We’ll talk to MIT social roboticist Cynthia Breazeal about how technology can manipulate our minds and emotions for good or ill, and with religion professor Robert Geraci about how technology is being used in religion, and why AI may need some spiritual training itself.

Watch Cynthia Breazeal’s TED talk here, and find out about her work on the MIT Media Lab website.

Meet the robots: Nexi, Mindar, and SanTO.

Finding Holiday Happiness Dec 15, 2024

Show notes

The holidays are supposed to be a time of joy. But all too often, the darker, colder days of winter, and even the stress of preparing for the holidays themselves, can lead people to feel something else: rushed, stressed, lonely, or even hopeless. How can you make sure this year is bright? Science shows that there's a wisdom to parts of traditional winter celebrations – a wisdom that's been honed over centuries to help us all find light, joy, and connection during the darkest and coldest time of the year.

Join Dave as he chats with Laurie Santos about how to unpack the psychological secrets of celebrations from Christmas, to Hanukkah, to Yule, and more. They’ll also discuss how we can put that wisdom into practice, whatever our beliefs, to make this season a happier and healthier one for all.

Laurie Santos hosts the podcast The Happiness Lab and is a Professor of Psychology at Yale, where she teaches the most popular class in the university’s history. Learn more about her work at her website.

Finding Hope in Dark Times (From the Archive) Dec 08, 2024

Show notes

This episode from 2023 is one of our all-time listener favorites. We're sharing it again for anyone who may have missed it, or could do with a refresher, especially at the holiday season!

Surveys show feelings of sadness and despair peaked in 2023. So as we look to the new year, it’s understandable why any of us might be feeling pessimistic, even hopeless. But these feelings aren’t written in stone. We always have a choice. It’s in these darkest of times, when all feels lost, that hope helps us find our way … not just to heal ourselves, but also the world around us.

On this episode, we’ll talk with the Pulitzer Prize winning New York Times columnist Nicholas Kristof, about how he remains motivated and hopeful, even while covering some of the most tragic events in recent history. And he’ll offer a little advice for ways we can all rise above despair.

And we’ll talk with Roshi Joan Halifax — ecologist, civil rights activist, hospice caregiver, and founder of the Upaya Zen Center — about the Buddhist-informed notion of wise hope, the equanimity it can bring, and the fierce compassion it can unleash.

Nicholas Kristof is the author of the book Chasing Hope: A Reporter's Life. Read his NYT columns here, and find out more about the cider he makes here.

Roshi Joan Halifax leads the Upaya Zen Center in Santa Fe, New Mexico. Learn more about her work on her website.

The Bad Place Nov 24, 2024

Show notes

Lots of religions embrace the idea of hell – a place of eternal punishment for wrong doers. But where did that idea come from? How has it changed through time? And how does a belief in it (or not) affect us while we’re alive?

We’ll talk with Bart Ehrman about the history of beliefs in hell from ancient Mesopotamia through modern Christianity. And with Shadi Hamid about why he thinks it can be a good thing for people to believe in hell, and how that belief shapes our political and social lives.

Bart Ehrman is the James A. Gray Distinguished Professor at the University of North Carolina at Chapel Hill, and the author of Heaven and Hell: A History of the Afterlife and Journeys to Heaven and Hell: Tours of the Afterlife in the Early Christian Tradition. Find out more about Bart’s work, including his many other writings about the New Testament and early Christianity, at his website.

Shadi Hamid is a columnist at The Washington Post, a research professor of Islamic studies at Fuller Seminary, and the author, most recently, of The Problem of Democracy: America, the Middle East, and the Rise and Fall of an Idea.

Near Death Experiences Nov 10, 2024

Show notes

People have been having Near-Death Experiences (NDEs) all over the world for as long as we can look back into history. And the strange thing is… these experiences seem to have a lot in common. Why? Is it a look into the afterlife? Is it just our neurons firing in weird ways as the brain dies?

We’ll talk to psychiatrist Bruce Greyson, one of the world’s leading experts on Near-Death Experiences, about the research that led him to rethink his understanding of the nature of life, death, and the continuity of consciousness. We’ll explore the science behind how these experiences can provide comfort, heal past trauma, and even create transcendent experiences that help us make as much sense of our lives as of impending death. And we’ll also consider the bigger question of what NDEs suggest, if anything, about our understanding of reality.

Bruce Greyson, M.D. is the author of “After: A Doctor Explores What Near-Death Experiences Reveal About Life and Beyond.” Find out more about his book, and his over 45 years of experience researching NDEs, on his website.

Here are links to the recordings of people you heard talking about their NDEs throughout the episode: Sharon Stone, Dr. Mary Neal, Renee Pasarow, Cherie Aimee, Jayne Smith.

Here’s a video of Dr. Gregory Shushan talking about his research on NDEs in ancient religions.
