How God Works: The Science Behind Spirituality

We will be back with a whole new season of How God Works on October 5th. In the meantime, we wanted to share some of our favorite episodes from the archives. 

A majority of people in the US believe that faith can heal. And while there isn’t any strong scientific data backing the idea of faith healing by divine intervention, there is a growing recognition that faith in the power of a person, religious ritual, or even medicine to heal can play a role in recovery via the placebo effect. Join Dave and his guests science wri...

We'll be back with a whole new season of How God Works on October 5th. But in the meantime, we wanted to share some of our favorite episodes from the archives.

Data shows that for many people, happiness takes a big dip around 50. But aging doesn’t have to be a crisis if we can figure out how to embrace who we’re becoming rather than hanging on to who we used to be. If done right, midlife can actually be a time of deepening joy and satisfaction. Join Dave as he talks to The Atlantic columnist Arth...

How God Works will be back with all new episodes this fall. In the meantime, we're taking the opportunity to share episodes from some of our favorite shows with you, our listeners. Today, we're excited to feature an episode from our friends at The Science of Happiness podcast, hosted by Dacher Keltner.

Summary: We investigate how Día de los Muertos, or Day of the Dead,  rituals strengthen family ties and cultural identity, and learn about its evolution from a 3,000 year old practice to a global celebration. We look at key elements like the ofrenda and explore ho...

How God Works will be back with all new episodes this fall. In the meantime, we're taking the opportunity to share episodes from some of our favorite shows with you, our listeners. Today, we're excited to feature a conversation from the podcast Kelly Corrigan Wonders, featuring Rainn Wilson, creator of the book and podcast Soul Boom. 

"Going Deep with Rainn Wilson on Spirituality"

Rainn Wilson (who you might know as Dwight Schrute) is making a serious call for a spiritual revolution based on joy, acts of service and being honest about our mixed natures. This i...

As more Americans move away from organized religion, the moral and emotional needs once met by faith communities remain. What can secular society borrow from spiritual traditions — ritual, meaning, belonging and moral imagination — to nourish the human spirit and strengthen our shared civic life? In this conversation, recorded live at the 2025 Aspen Ideas Festival, Dave explores how sacred wisdom can still guide character, compassion, and community in a post-religious age with Krista Tippett, Father Greg Boyle, and Rabbi Shira Stutman.

Krista Tippet is the creator and host of the award winning podcast On Being and an awardee of t...

The spiritual practice of speaking in tongues –a form of communication with the divine through speaking words in an unknown or unrecognizable language– has invited a lot of speculation and skepticism over the years. To many, it seems like the stuff of horror movies, or old-timey religious revivals. But charismatic Christianity, for which speaking in tongues is a central practice, is one of the fastest growing Christian movements in modern history.  So why has it not only persisted, but recently gained momentum? What exactly is happening to the mind and body when people engage in this practice? 

We’ll...

What is prayer? And why do it? People pray for all kinds of reasons, and in all kinds of ways: alone, together, aloud, in silence, from memory, or from instinct. But whatever form it takes, there’s a reason prayer has been part of just about every spiritual tradition out there: its effects run deep. 

On this episode, we’re digging into the science and spirit of prayer. We’ll talk to neuroscientist Andrew Newberg about what prayer does to our minds and bodies, and how it helps shape us as people. And friend of the show Rabbi S...

There's a lot of talk these days about a crisis of masculinity. But is it a genuine problem or just another culture war talking point? 

In this special episode, we’ll talk to writer and researcher Richard Reeves about the real and worrying data around the male struggle for meaning and purpose, and what role community and ritual can play in helping men find answers. We’ll also hear from Dr. Russell Moore and Pastor Rasool Berry about how and why religion can help support men, but also the dangers it can pose if they follow it down...

 Hey listeners, we'll be back in two weeks with a special episode looking at the multiple challenges facing men in America today. But while you wait, we wanted to share an episode from Season 2 of our show that feels especially relevant to that conversation. Think of it as a prequel or primer, because part of the problem, and possibly part of the solution, may have to do with how boys become men in the first place. We hope you enjoy!

When you’re a teenager, you’re kind of between two worlds. You’re leaving...

For centuries, Western science and philosophy have struggled to explain what consciousness is and where it comes from. What if the answer to both those questions is: everything?

On this episode, we dive into panpsychism: the idea that consciousness may not be limited to humans, or even living beings, but could be a basic property of reality itself. We’ll talk to philosopher Philip Goff about why this idea is gaining attention in academic circles, and to theologian Joanna Leidenhag about how panpsychism aligns with spiritual traditions from across cultures and throughout history. We’ll also ask: coul...

People find faith or change faiths for many reasons: marriage, raising a family, dealing with  grief or crisis. But sometimes it happens the other way around… faith finds you. A believing takes hold, a sense that something divine is there. And maybe not in the way or role that you might have expected. 

It’s not uncommon. Data show that these types of experiences happen to about 30% of people. On this episode we’ll talk to one of these people –New York Times columnist and best selling author David Brooks– about his unexpected encounter with faith and what came af...

Many would agree there are few things better than sharing a delicious meal with the people you love, which is one reason why breaking bread together is a cornerstone of religions the world over. But so too is the opposite - going without food.  From Ramadan to Yom Kippur to Lent, fasting is an important ritual in many faiths. But why do so many religions periodically take away the very thing that nourishes our bodies and souls?  

On this episode we'll talk with Khalil-Abdur Rashid about the role fasting plays in Islam, and why not eating and dri...

We often think of belief as a religious or cultural idea that is a hallmark of modern humans. But what if the early sparks of belief burned in our ancestors’ minds long before modern humans walked the earth? What if beliefs about some of the biggest questions out there, like what happens after death, weren’t just pondered by Homo sapiens?

On this episode, evolutionary anthropologist Agustín Fuentes takes us on a journey spanning millions of years, from our primate relatives in the deep past to the complex spiritual and cultural traditions we know today. Along the w...

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 ofte...

Join us for Season 8 of How God Works, starting next week!

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 cogniti...

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...

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...

Faith has always been a strong force in human history – but in modern times, it may feel antiquated to have it. This is an episode of the How to Be a Better Human podcast in which Dave talks about his research exploring questions of faith, his findings, and why we shouldn’t leave spiritual wisdom behind, even in the age of science. 

Hosted by comedian Chris Duffy, How to Be a Better Human features conversations that uncover sharp insights and give clear takeaways on how you can improve your life.  From your work to your home and your h...

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 abo...

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...

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 E...

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 scien...

There’s no question we’re living in difficult times that lead many of us to adopt a cynical outlook. But while cynicism might feel smart, science shows it’s corrosive not only to our own wellbeing, but to society as a whole. We’ll talk to Stanford Professor of Psychology Jamil Zaki about the surprising benefits that a willingness to trust in the goodness of others can offer, and how to build this skill in a wise way through habits of mind and action.

We’ll also speak with political writer Peter Wehner about how cynicism leads to t...

We spend a lot of time on How God Works talking about how spirituality can offer tools to become better versions of ourselves.  And while learning to be happier, healthier and more resilient are all positive things to strive for, they can also lead us down a different path - an obsession with productivity and self-optimization… which can lead to a culture of trying to grind or life-hack our way through everything.

But what if the secret to success lies in doing less, not more? On this episode, we’ll explore the Chinese concept of wu wei, effor...

Regret can be a double-edged sword.  It can be painful, and enduring, but we can also learn important lessons from it - IF we treat it right. Most religions speak of forgiveness and compassion, not only toward others but also toward oneself. Still, letting go can be difficult to do at times. So how do we learn from regret and start anew?

Dave speaks with best selling author Daniel Pink, and renowned Buddhist teacher Sharon Salzberg to learn about the science of regret and how some spiritual wisdom and practices can help us move beyond it and b...

For many people, the word “sin” is associated with harsh judgment and shame. Or, it’s used to talk about guilty pleasures like consuming decadent desserts... But is this concept as harmful or outdated as it seems?

Join Dave as he talks with Elizabeth Oldfield about Christianity’s Seven Deadly Sins, and how reconceptualizing them for modern life can offer a science-backed user’s manual of sorts to find joy and connection in this world, whatever your beliefs.  

Elizabeth Oldfield is host of The Sacred podcast and author of the book Fully Alive: Tending to the Soul in...

Join us for Season 7 of How God Works, starting next week! 

We've had a lot of new listeners join us of the past year, so while we're hard at work on our next season, we thought we'd share some favorites you might have missed from the archives.

Have you ever heard a voice, seen an image, or felt a presence around you that you couldn’t explain? If you have, you’re not alone. 

More people than you might think report having these kinds of experiences. For some, it can be easy to write these off as tricks of the mind. But for others, especially the relig...

We've had a lot of new listeners join us of the past year, so while we're hard at work on our next season, we thought we'd share some favorites you might have missed from the archives.

As a society that fears death, we tend to avoid the subject. But the key to having a positive end-of-life experience might come in doing just the opposite. 

On this episode, we’ll hear from philosopher Simon Critchley, Boston-area chaplains Ruth Delfiner, Sarah Byrne-Martelli, and Maude Quinn, and Threshold Choir singer Leigh Davis about what makes a good death, and...

We've had a lot of new listeners join us of the past year, so while we're hard at work on our next season, we thought we'd share some favorites you might have missed from the archives.

For centuries, many cultures have used psychedelics to induce mystical states. And while in the US they’ve mostly been used as recreational drugs, interest in their power to offer a rapid route to transcendence has recently been growing. But in our haste to use these chemicals to alter, and perhaps even heal, the mind, we might be losing sight that wi...

We've had a lot of new listeners join us of the past year, so while we're hard at work on our next season, we thought we'd share some favorites you might have missed from the archives. Since this episode was first published, the Surgeon General has issued an advisory about the effects of social media on youth mental health, and, more recently, called for warning label on all social media platforms. 

Time with family, friends and loved ones is supposed to be at the center of the holiday season … but in our screen-dominated world, how...

Hey Listeners, as we plan future seasons, we'd love to know what you appreciate most about the show... and what you think we can improve or would like to see us cover. If you have five minutes to spare, please consider responding to our audience survey. Thanks!

Hey Listeners, we also want to hear from you! Please take a few minutes to fill out our audience survey and be a part of shaping future seasons. 

Anger, loneliness, and despair are hitting record levels in the US. Our social and political fabrics are fraying. Is the turn away from religion in the US part of the problem? And if so, might a spiritual renaissance (even among the secular left) help us find new ways to flourish? Join Dave as he talks with podcast host Krista Tippett and US Senator Chris Murphy about the role spirituality (o...

Science and religion can often seem at loggerheads. But does it have to be that way? Dr. Francis Collins, one of the world’s leading scientists, doesn’t think so. As an internationally renowned geneticist, a recent past director of the US National Institutes of Health (where he helped guide the U.S. response to COVID), and an avowed Christian, he’s a leading voice for how and why belief in God can be rational, and for a greater openness to science among Evangelical Christians.

In a special live interview, Dave talks with Francis about his journey from s...

When it comes to how we treat other animals, humanity’s track record is spotty at best. Has it always been that way? And how do the beliefs we hold about animals shape how we treat them? Are they really as different from us as Western culture has long suggested?

Join Dave as he speaks with anthropologist Dave Aftandilian about how different religious traditions may play a role in influencing the way people relate to other animals, and with biologist turned wildlife filmmaker and writer Tom Mustill about what the latest advances in science are revealing about an...

Do you feel connected to nature’s rhythms and the peace that they provide? Are cooking, crafting, or other small daily rituals a form of spell work or spirituality for you? If you’re a witch, the answers are a definite yes.

Long in the shadows, Wicca and witchcraft are now on the rise. Join Dave as we explore what’s driving interest in these religions and dispel some of the stereotypes around them.  We’ll talk to Thorn Mooney, a Wiccan high priestess and religious studies scholar  about what it means to be a witch and why many p...

Ever heard of the Bartonian Metaphysical Society? How about the Druze? If you’re like most people, you probably haven’t. On this episode, we ask: What’s it like to be a member of a tiny religion in a world dominated by “Big God”?

From the early days of new religious movements to the precarious old age of ancient faiths, join Dave as we explore the unique experiences, joys and challenges of being one of the few rather than one of the many. We'll talk to sociologist Susan Jean Palmer about what religions are like when they're br...

Religion is often about powerful beings coming down from the skies and humans yearning to go up to join them. Does that mean we can swap aliens in for God? More and more people seem to think so. In fact, many spiritually-minded people are looking to UFOs as opportunities to commune with enlightened alien teachers. Some believe they’re even aliens themselves, sent here to prepare us for a new age. But when religion gets mixed with conspiracy theory, things can sometimes take a darker turn.

Join Dave as he speaks with religious studies professor Diana Walsh Pa...

What makes a trip a pilgrimage? And why have people from across the globe made these treks for millennia? Is it the destination that makes these journeys so important to so many cultures? Or is it the community and meaning-making that happen along the way?  And how are people changed by the experience after they come home?

Join Dave as he talks with writer and New York Times contributor Aatish Taseer about what he saw last year when he went on pilgrimages into the hearts of three faiths. And with psychologist and leading pilgrimage scholar Heather Warfield, a...
