Discussions about religion from a psychological—or more broadly scientific—point of view require great care. For most believers, faith is not just an intellectual position. It is a lived emotional landscape, developed over a lifetime. Religious beliefs are often taught in early childhood, and they can represent a fundamental bond and a shared culture with parents and ancestors, sometimes going back centuries.
Religious stories, passages from religious texts, and familiar rituals can become like a “native language,” in the sense of the fluency and familiarity people develop through repeated exposure and practice over many years. Shared religious beliefs can be a bridge to memories of parents—alongside memories of fishing together, playing baseball, going camping, playing music, or cooking together. In that sense, religion is not simply an “idea.” It is the atmosphere of the family home—a mood, a shared vocabulary, and a living link to one’s past.
Unlike hobbies, however, religion carries a far heavier weight. A parent might be mildly disappointed if a child dislikes baseball; with religion, the stakes are much higher. Parents may insist—with fear, sadness, anger, or a sense of emergency—that their children must remain within the same faith. If the children stray, guilt can be induced in ways that are far deeper than ordinary family disagreements. In extreme cases, the divergence leads to estrangement or disowning. It is hard to overstate how high the emotional cost can be, in some families, for simply asking religious questions out loud.
A huge reason why many people are religious is because their most beloved people have been religious: parents, grandparents, mentors, teachers, community leaders, or admired public figures (for me, someone like Desmond Tutu or Martin Luther King). When these beloved figures explain their moral courage, comfort, or meaning as flowing from God, the religion becomes fused with the goodness of the person. Out of love and respect, many people continue the same faith—not because they have evaluated the evidence with fresh eyes, but because questioning the belief can feel like questioning the beloved person. It can feel, emotionally, like an insult to one’s parents, or a betrayal of one’s ancestors, or a rejection of one’s own story. Over time, religion can become so interwoven with identity that challenging it feels less like an intellectual inquiry and more like a renunciation of a precious part of oneself.
Beyond family attachment, there is the brain itself: the human mind is remarkably capable of mystical experience. Many people have had moments—alone or in groups—of awe, presence, unity, transcendence, or “spiritual certainty.” Whatever one concludes philosophically, the raw fact is that such states are part of the normal range of human experience. And they can be intensified or triggered by particular brain states: by drugs that act strongly on serotonin and dopamine systems, by sleep deprivation, by stress, and in some neurological conditions. Wilder Penfield’s neurosurgical stimulation work in the mid‑20th century, for example, illustrates how focal stimulation can produce vivid sensory phenomena and “dreamy states” that feel subjectively profound. In temporal lobe epilepsy, similarly, some people report intense subjective or spiritual states in association with seizure activity.
A point that matters here—psychiatrically—is that the brain constantly seeks to make sense of things. When something unusual happens in perception, emotion, or bodily feeling, the mind strains to explain it. Often the explanation feels logical even when the proximate cause is biological. This is not a dismissal; it is simply a basic property of human cognition. A powerful feeling state can be interpreted as “God,” “fate,” “destiny,” “the universe speaking,” or “a presence,” depending on one’s cultural vocabulary and expectations.
The same instinct often fuels belief in other mystical phenomena, such as ghosts, spirits, or psychic abilities. These beliefs can act as a lens for understanding reality, where coincidences are read as evidence of a hidden world. This can make life feel “magical” in a deeply satisfying way, offering a sense of specialness and wonder akin to the feeling one gets from a fantasy story like Lord of the Rings or Harry Potter.
The vocabulary we use to describe these states matters. Many religious phrases are woven into everyday language; other words and symbols have roots in ancient mythology. For example, our word “panic” comes from the Greek god Pan, and our month “January” is named for the Roman god Janus. Language forms a lens—deeply ingrained in the brain through memory infused with emotion—through which we describe and interpret experience; in a religious household, one naturally develops the habit of interpreting events with religious references in mind, because those are the interpretive tools one has practiced. And historically, in some homes and communities, scripture was not merely a weekly reading—it was a central text around which literacy and moral education were organized.
Religion has also served, in many families and cultures, as a framework for moral development. Lessons about how to be kind, how to deal with guilt or mistakes (“sin”), how to navigate conflict, how to be a decent citizen, how to face suffering and loss—these have often been taught through weekly sermons, study of sacred texts, and the social modeling that occurs in a community of adults trying (at least some of the time) to be better people. Daily habits—such as saying grace—can instill a rhythm of gratitude. Religious services often use architecture, music, and ritual to evoke awe and reverence. And it would be dishonest to deny the artistic beauty and power that has emerged from religious contexts: sacred music, religious painting and sculpture, the architecture and acoustics of churches, cathedrals, temples, mosques. Many of my own favorite pieces of music are deeply tied to that history.
It is no surprise, then, that for many people their happiest memories—friendship, loyalty, meaningful service, celebration, “ecstatic” spine-tingling moments of being emotionally moved—are associated with church or religious community. Many believers interpret these peak emotional states as manifestations of God. As a psychiatrist, I see them as natural human emotional states that can occur whenever there is meaningful absorption shared by a group of like-minded people: in a cathedral, at a concert, at a political rally, in nature, or even at a sports event. The emotion is real; the interpretation is culturally shaped.
This communal power is often concentrated through the figure of the minister. Some ministers are wonderful orators: gifted storytellers with compelling voices, humor, and genuine moral seriousness—sometimes with a breadth of knowledge about history and literature that makes their sermons a kind of accessible public humanities. Some of the great orators in modern history, such as Martin Luther King, were ministers. Churches have been one of the few sustained modern venues where people regularly gather to hear impassioned, ethically themed rhetoric delivered with craft and intensity. Mind you, the same infrastructure can be used for darker purposes: demagogues can weaponize charisma, spectacle, and group emotion to fuel intolerance.
Religion can also function as refuge. Many people who feel lonely, adrift, or ungrounded are drawn to a religious or spiritual group because it offers instant community: new friendships, mentorship, comforting rituals, structure, sometimes even material support, and a ready-made language for meaning. This differs from many other community organizations because the commitment is thicker: it is not merely “we play badminton together,” but “we share a destiny that goes beyond this life.” It is a little bit like an orphan finding an adoptive family and then, quite naturally, adopting the family’s beliefs as part of belonging.
This is also part of why religious (and ideological) communities can become so resilient: they meet deep social and psychological needs. Research on radicalization and extremist commitment—work associated with researchers such as Nafees Hamid and colleagues—has explored how peer influence, identity, and social exclusion can harden commitment in tightly bound groups. The point here is not to equate ordinary religious life with extremism, but to recognize a shared human vulnerability: when belonging and identity are fused to belief, questioning belief can feel like social annihilation.
Perhaps the most potent function of religion, however, is its relationship to mortality. Religious beliefs, services, and rituals have helped countless people cope psychologically with death and loss. You can have less fear about death—your own death, or the death of someone you love—if you believe that death is an entry point to another world, and that separation is temporary. I think it is also a psychological skill, for any person, to practice acceptance of the fact that everything ends: every pleasant experience, every day and night, every song, every meal, every firework, every life, every mountain. They all have a beginning, a middle, and an end, and then they are gone—sometimes literally in a puff of smoke. It is entropy in action: one of the underlying realities of the universe. On some level, religion can interrupt that acceptance by bypassing finality with an imagined eternity. This calms fear. But it can also be a kind of avoidance—a comforting story that softens grief by blunting the truth.
It is easy to see, then, why the idea of “taking away” religion can feel like taking away a rich cultural inheritance and a shield against despair. Many people imagine that without religion they would be left adrift, empty, or nihilistic. I do not believe that is a necessary outcome, but I do believe it is a real fear—and a psychologically understandable one.
There is another layer as well: persecution and trauma. Many individuals and communities have been oppressed because of their religion, sometimes brutally—often by other religious groups, including rival branches of the same tradition. This happened to my own ancestors, most recently in my grandmother’s generation near the beginning of the Soviet era. There were experiences of fear and brutality that she could never speak about for the rest of her life. Trauma cements belief.
Mind you, people who questioned the religious beliefs of their time have also been persecuted and executed through the ages. The point is simply that fear—whether fear of outside violence, or fear of internal exclusion—can make belief feel like survival.
Finally, we should acknowledge the stigma surrounding the word “secular.” To many ears, it evokes coldness: a painting devoid of color, music devoid of emotion. It can evoke memories of totalitarian states that discouraged religion. Some people equate secularism or atheism with nihilism, criminality, or a lack of moral grounding. Many believers sincerely think that without God there would be moral decay.
Politics amplifies this. In many contexts, public piety is rewarded, and some leaders clearly perform religiosity to secure loyalty. We see this today in American politics, where leaders with life histories that seem far removed from traditional piety can simply hold up a Bible for a photo op—a performative gesture that successfully rallies support from religious followers by trading on the symbols of their faith.
All of this is why critique of religion, to be intellectually honest, must begin with an honest accounting of religion’s benefits: the attachment, the community, the rituals, the moral vocabulary, the beauty, the refuge, the buffering against death. These are real goods, even when the supernatural claims do not align with the evidence. And understanding these benefits is not a concession—it is a prerequisite for explaining why religion persists, and why leaving it can be psychologically and socially costly.
