Huberman Lab Podcast

Episode: Science & Health Benefits of Belief in God & Religion | Dr. David DeSteno
Date: August 25, 2025
Host: Andrew Huberman, Ph.D.
Guest: Dr. David DeSteno, Professor of Psychology, Northeastern University

Overview: Main Theme and Purpose

In this episode, Dr. Andrew Huberman interviews Dr. David DeSteno about the intersection of science and religion, focusing on the mental and physical health benefits of belief in God and religious practices. The conversation critically examines the perceived incompatibility between science and religion, the evidence on the effects of religious rituals and belief, the mechanisms by which prayer and community impact wellbeing, and broader philosophical questions about belief, morality, rituals, suffering, and death anxiety. Dr. DeSteno offers a scientific, non-dogmatic framework for understanding why religious practices endure and benefit individuals and societies, while maintaining humility about what science can and cannot answer regarding the existence of God.

Key Discussion Points & Insights

1. Compatibility Between Science and Religion

• Science vs. Religion: A False Dichotomy
  • Many assume belief in God and scientific reasoning are mutually exclusive. Dr. DeSteno argues this is a flawed view:

    “Any scientist who tells you they know for sure God doesn’t exist, you shouldn’t listen to.” [03:22, DeSteno]

  • Science requires falsifiability; the existence of God is not a testable hypothesis, so arguing about God’s existence is not scientifically useful.
• Living With Unanswered Questions
  • The “does God exist?” debate tends to polarize rather than unite. Many scientists and religious individuals see no tension—e.g., the Catholic Church funds astronomy; the Dalai Lama supports neuroscience.
  • Example: Francis Collins (geneticist) sees his faith and science as compatible.
  • Dr. DeSteno suggests focusing not on proof, but on the observable benefits of religious practice.

  “I like to put that question to the side. What I’m interested in is the data that shows engaging with religion makes life better for people.” [07:02, DeSteno]

2. Philosophical Frames: Pascal’s Wager & Russell’s Teapot

• Pascal’s Wager:
  • Rational to believe in God if faith offers potential infinite reward, but also if it brings measurable benefits here and now.
• Empirical Benefits:
  • Epidemiological data:
    • Regular religious engagement cuts all-cause mortality by 30%, and death from cancer/CVD by 25%.
    • Reduces anxiety/depression, boosts life meaning and flourishing.
    • Benefits not entirely explained by community—religious community has greater effects than other social clubs.
• Russell’s Teapot & Burden of Proof:
  • Russell’s Teapot analogy: The philosophical burden is on those making unfalsifiable claims, not on skeptics.
  • Dr. DeSteno: Both belief and disbelief require faith; absolute proof doesn't exist for either.

3. Religious Practices as Behavioral Tools (Science & Health)

• Experimental Insights: Meditation & Compassion

  • Experiment: Eight weeks of meditation vs. control increased helping a person in pain from 15% to nearly 50%.

    “We tripled the rate at which somebody felt compassion for somebody else in pain and was willing to help them.” [28:47, DeSteno]

  • Meditation reduces anger responses and punishing behavior in lab contexts.
  • Prayer & Breathwork:
    • Formulaic prayers (rosary, sutras) decrease respiration rate, boost vagal tone, reduce stress.
    • Similar effects as secular breathwork but driven by ritual format.

• Rituals as Packages of Life Hacks

  • Cultural rituals (e.g., mourning, eulogizing, covering mirrors in Shiva) have psychological and physiological bases.
  • Example: Motor synchrony in rituals boosts empathy and helpfulness.

    “Rituals are like sophisticated packages of life hacks… a ritual is like a symphony.” [37:05, DeSteno]

4. Religion, Community, and Loneliness

• Religious Community Offers More Than Social Clubs
  • Religious gatherings intensify social bonding through synchrony (singing, praying together).
  • Religious belief (even without community) reduces loneliness by providing a sense of permanent relationship (with God).
  • Data suggests both religious practice and belief in God are associated with reduced loneliness.

5. Good, Evil, and Moral Psychology

• Innate Capacity for Both Good and Evil
  • People are not inherently saints or sinners, but adaptively moral based on circumstances and reputation.
  • Cheating experiments: Most people cheat when unobserved, but religious primes decrease cheating.
  • Rituals cultivate emotions (especially gratitude) that nudge behavior toward honesty and prosociality.

  “Religions curate our emotional lives… The most common prayer is a prayer of gratitude.” [69:58, DeSteno]

6. Death Anxiety, Afterlife, & Time Perception

• Contemplating Death in Religious Practice
  • Religions address death anxiety by fostering beliefs in the afterlife or by rituals that promote acceptance.
  • Certainty (belief or disbelief in afterlife) is less anxiety-provoking than uncertainty.
  • Rituals expand people’s sense of time, connect them to history and future generations, and reduce existential overwhelm.

7. The Emergence, Branding, and Persistence of Religions

• Formation of New Religions & Cults

  • 100–200 new “religions” form each year, most don’t last.
  • Stickiness depends on meeting spiritual and communal needs, not just charismatic leaders.
  • Experiences like Burning Man deliver real spiritual connection, can draw people back to or into faith.

• Religion vs. Cult:

  • Thin barrier; cults center on charismatic, often exploitative leaders; mainstream religions endure by meeting broader human needs.
  • Religion is a neutral spiritual technology—can be used for good or ill.

• Modern Branding:

  • Perceived “brand” of a religion (loving, punitive, inclusive) powerfully colors public opinion and adoption.

8. Science, Belief, and "Living in the Question"

• Reconciling Awe and Knowledge

  • Scientific understanding doesn’t diminish the sense of miracle or awe; understanding can enhance appreciation (citing Feynman).
  • The “line of overwhelm”—where comprehension fails—often triggers spirituality or faith.
  • Dr. DeSteno: Even as a scientist, the existence or nonexistence of God is undecidable; what matters is the pragmatic impact of religious practice.

  “Sometimes it’s in the doing of the practice that the understanding comes later.” [138:19, DeSteno]

• Humility and Open Inquiry

  • Dr. DeSteno, personally agnostic, advocates trying out different practices and communities, emphasizing experiential learning over dogmatic allegiance.

  “I’m an agnostic… but I’m on this journey to find out. And I hope… I take my listeners with me on that journey.” [135:20, DeSteno]

Notable Quotes & Memorable Moments

On Science & Unprovable Questions

• “Absence of evidence is not evidence of absence.” [03:22, DeSteno]
• “We can’t run an experiment to prove or disprove God… all it does is polarize us.” [03:22, DeSteno]

On the Health Benefits of Religion

• “People who engage with religion, not just believe but actually engage, over a 15 to 20 year period, it cuts all-cause mortality by 30%.” [10:10, DeSteno]
• “It’s not just community… The effect size is larger for religious community.” [12:36, DeSteno]

On Compassion and Meditation

• “In the meditation condition, it was close to 50% of people who [helped]. Right? We tripled the rate at which somebody felt compassion for somebody else in pain.” [28:47, DeSteno]

On Rituals & the Mind-Body Connection

• “Rituals are like sophisticated packages of life hacks… a ritual is like a symphony.” [37:05, DeSteno]

On Death & Loneliness

• “Being alone is not the same as being lonely.” [73:25, DeSteno]
• “People who really believe in an afterlife, they have the least anxiety about death… The group that is the most anxious are the people who don’t know.” [91:58, DeSteno]

On Morality

• “We did not evolve to be saints. We did not evolve to be sinners. We evolved to be adaptive.” [64:20, DeSteno]
• “Religions curate our emotional lives. The most common prayer is a prayer of gratitude.” [69:58, DeSteno]

On Trying–Then Understanding

• “Naesh vinishma… we will do and then we will understand.” [138:19, DeSteno]

Overall Takeaways

• Science and religion are not inherently antagonistic; most people occupy a pragmatic middle ground.
• Religious practices—especially when involving community, ritual, and emotional cultivation (e.g., gratitude)—are linked to impressive health and psychological benefits.
• Religion functions as an adaptive “technology” for promoting flourishing: reducing stress, anxiety, mortality, and loneliness; increasing prosociality, meaning, and community.
• Participating in religious practices can benefit individuals even without belief, and believing without practicing does not confer the same benefits.
• Awe, mystery, and humility are central to both scientific inquiry and spirituality; accepting what we can’t know is itself rational.
• The persistence of major religions and the failure of most “new religions” hints at a deep correspondence between ritual practices and enduring human needs.
• Dark sides exist: religious technologies can also be misused in cults or conflicts; critical inquiry and ethical vigilance are essential.
• In exploring meaning, mortality, and morality: ‘do’ first, and understanding may follow.
