How God Works: The Science Behind Spirituality
While religion and science often seem at odds, there’s one thing they can agree on: people who take part in spiritual practices tend to live longer, healthier, and happier lives. The big question is: Why? In How God Works, professor Dave DeSteno takes us on a journey to find out how spirituality impacts our minds and bodies, as well as the world in which we live.He speaks to leading scientists and philosophers, religious thinkers, and thought leaders to explore what we can learn from the world’s faith traditions to help us meet some of life’s biggest challenges. Along the way, he’ll look at how we can adapt and use spiritual practices in our own lives, whatever our beliefs, including none at all.It’s by working across the boundaries that usually divide us – science versus religion, one faith versus another – that we’ll find new ways to make life better for everyone.

What’s Old is New Again
It's not news that the US is becoming more secular. People have been drifting away from religion for decades, and that trend is accelerating right now in people under 40. But there is a small but growing trend in those same generations of people who are seeking just the opposite. These people are looking to older and more orthodox forms of faith to find meaning, purpose, and community even in the face of what many might consider to be more sexist and less tolerant ideas.
Join Dave as he talks to two Millennials who have converted to more traditional forms of faith about the reasons for their choice, how it affects their lives, and why they believe these more ancient forms of religiosity have value… perhaps now more than ever.
Kelsey Osgood is a writer and convert to Modern Orthodox Judaism, currently working on a book about religious conversion among women, scheduled to be published in 2024. Find out more about her on her website.
Julia Yost was raised Catholic, but transitioned to a more traditional form of Catholicism as a young adult. She is a senior editor and regular contributing author at First Things magazine. She also authored this opinion piece about young converts in The New York Times.

Can Ancient Wisdom Help Gen Z's Stress & Unhappiness?
This episode is an edited version of a live event held at WBUR’s Cityspace on May 15, 2023. A full-length video of the event is available here.
For decades, studies from around the globe showed that happiness followed a U-shaped curve across the lifespan. For many people, the teens and twenties were some of the happiest and most carefree times of life — a period to be enjoyed before happiness began to drop and hit its low point around 50. BUT, over the past 10 years, a seismic change has taken place. The front end of the happiness curve collapsed, meaning that teens and twenties are now the most unhappy time of life.
From the increasing use of social media, to being isolated from friends during the pandemic, to the academic pressures of applying to college, to growing up in a world that feels threatened from climate change, gun violence, and political strife, the reasons for this crisis in mental health are many. The solutions, however, have been few.
But there’s a growing sense (and data) that when it comes to finding a way through challenging times, looking back at ancient wisdom for strategies on how to thrive — how to find joy, peace, empathy, and meaning — can help.
Join Dave and a panel of experts and voices from Gen Z to explore the science behind when and how secular and spiritual practices might help young adults (and really any of us) deal with the stresses and disconnection of modern life, whatever our spiritual beliefs (including none at all).

Moving Beyond Us vs Them
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.

Sacred Sound
Music has the power to transform and connect us, no matter our native tongue. In many ways, it's a language unto itself. It ties us to memories...to people....to places. It heals us, promotes compassion and empathy. It unites us not only to each other, but according to many people, perhaps even to something greater.
On this episode we’ll take a look at what’s going on in our brains and bodies when we sing sacred songs together... or listen to jazz. And why from Jewish nigunim to John Coltrane, music can deepen our connection with the divine, each other, and even with ourselves.
Episode guests:
Dr. David Michael Greenberg is an award-winning American psychologist, social neuroscientist, musician, and entrepreneur. Find out more about his work on his website.

The Flow of Craft
What do we get out of making things with our hands? Traditions the world over incorporate crafts into their religious practice, and for secular people, that experience of getting “in the zone” while weaving or working with wood or clay can also feel meditative, even spiritual.
So maybe it’s worth asking: Is there a craftsperson in all of us that we should occasionally step away from our devices to nurture? And could craft, even for the non-artist, be a way to connect with spirituality for us all?
We’ll talk to Claremont Graduate University psychologist Jeanne Nakamura about what characterizes the experience of “flow” that so many makers experience while they work. And we’ll talk to Stuart Kestenbaum, poet and former director of the Haystack Mountain School of Crafts, about how people of all skill levels can benefit from working with their hands.
We’ll also hear from two renowned makers: Tlingit glass artist Preston Singletary and Tibetan mandala master Losang Samten.

God is Green
Were the Earth and all its resources created just for our benefit? Do plants and animals exist solely for us to consume? Or should we be viewing our role on this planet differently? When it comes to protecting the environment and addressing climate change, religion has had mixed results. Why is that?
With Earth Day almost upon us, we thought it would be the perfect time to take a look at how religion plays into our relationship to the Earth. We’ll talk to psychology professor Jesse Preston about how the way religious people practice their faith may influence their environmental attitudes and behavior. And we’ll speak to the Reverend Dave Bookless about the theological case for Christians to go green and how to make environmental action a spiritual practice.
Jesse Preston is an Associate Professor of Psychology at the University of Warwick. Learn more about her work here.
As the director of theology at A Rocha International, Reverend Dave Bookless is helping to advise and lead many Christian-inspired environmental projects around the globe. Learn more about what he does here.

The Power of Awe
Awe fills us with wonder -- we feel small in the face of things that seem vast, inspiring, almost beyond comprehension. So it makes sense that spiritual experiences often inspire awe. But new science is showing it can also work the other way around.
Awe from any source -- nature's beauty, art and music, even others’ noble acts -- can actually nudge us toward becoming more spiritual -- toward believing in the divine. And along the way, awe offers a host of benefits to support us. From reducing stress, to improving health, to even reducing loneliness, awe soothes our souls, and if we're open to it, pushes us to connect with something greater.
Dacher Keltner is the author of Awe: The New Science of Everyday Wonder and How it Can Transform Your Life. Find out more about the book and Dacher’s work here.

From The Happiness Lab: Yoga of the Mind
While we’re working on Season 4, we wanted to share a special episode from another podcast we love, The Happiness Lab.
On The Happiness Lab, Dr. Laurie Santos explores all the ways we get our happiness wrong and what we can do to really feel better. She walks through the latest evidence-based strategies for improving your mental health, sharing practical advice on what will really bring more joy.
In this episode, Laurie looks at what a centuries-old Sanskrit text, The Yoga Sutras, can teach us about improving both the body and mind. The author, Patanjali, makes clear that the poses and stretches are only part of the picture - we also need to be kind, contemplative and grounded. Jessamyn Stanley (yoga teacher and author of Yoke: My Yoga of Self-Acceptance) takes Laurie through Patanjali's text, saying its lessons "can be applied in every circumstance, no matter who you are or where you are."

How to be a Great Ancestor
What do we owe future humans? In principle, it seems obvious that we should do what we can to make life better for the generations that follow, just as our ancestors did for us. But while most of us agree that doing this is the right thing, it can be hard to put into practice while also avoiding some of the pitfalls that often afflict growing philosophies like effective altruism and longtermism.
Join Dave as he speaks to Harvard psychologist and philosopher Joshua Greene about what drives our moral instincts, and to futurist Ari Wallach about how tapping into spirituality and emotion can help us become better ancestors to those yet to be born.
Find out more about Joshua Greene’s work, including how to buy his book Moral Tribes: Emotion, Reason, and the Gap Between Us and Them, on his website. Also, check out Giving Multiplier, a donation system Josh co-created based on research about how to improve charitable giving decisions.
Ari Wallach is the author of Longpath: Becoming the Great Ancestors Our Future Needs. Find out about the book and Longpath in general here. You can also read Ari’s article for Wired about addressing short-termism, or watch his TED talk.
