On Religion

If you take evolution seriously, you end up looking at human behavior a little differently. Not as a set of ideas we freely choose in a vacuum, but as a pile of habits, stories, and institutions that helped our ancestors make it through another winter and raise children who did the same.

From that angle, religion looks less like an odd glitch in an otherwise rational species and more like a plausible adaptation. Not “true” or “false” in the scientific sense. Useful or not useful. Sticky or not sticky. Does it help people endure, bond, and build families, or does it get selected against?

This isn’t an original thought. I googled it and discovered that plenty of people have made versions of the same argument. I’m leaving it here anyway, because it still feels clarifying to say it plainly.

Richard Dawkins comes up a lot in this territory. In The Selfish Gene, he introduced “memes” as a way to talk about ideas that replicate and spread, roughly the way genes do. Later he called religion a particularly potent meme, even “a virus of the mind.” His case is familiar, people hold beliefs without evidence, act irrationally, and sometimes become intolerant of outsiders.

Maybe he’s right about some of the pathologies. But the part that always feels missing to me is the other half of the story. If religion were only a mental infection, why did it show up so reliably across cultures, and why does it keep reappearing even after revolutions, reforms, and modern schooling? When I hear “religion as meme,” I don’t only hear “bug.” I also hear “feature.” A mechanism that, in many contexts, helped with survival, reproduction, and cohesion.

Survival

There’s a cliché about turbulence, “nobody’s an atheist on a plane.” It’s a joke, but it points at something real. When people feel cornered, many of them reach for a story that can hold fear without collapsing into panic.

Sometimes that story is God. Sometimes it’s fate, ancestors, karma, a sense of calling, a vow, a community that will not let you disappear. The important part is not the metaphysics. It’s the psychological scaffolding. A framework that turns “this is meaningless” into “this is a test,” or “this is a chapter,” or “this will be redeemed.” Those frames can keep someone alive long enough for their circumstances to change.

I’ve heard versions of that from religious friends and relatives my whole life. Not as a debate point. As a description of how they got through grief, unemployment, addiction, chronic pain, betrayal. They’ll say things like: I felt held. I was carried. I wasn’t alone. Whether you think that presence is literally real or not, it has a practical effect. It gives people a reason to keep going on days when reason is thin.

That’s why Dawkins’ hostility has always felt incomplete to me. If you only tally the harms, you miss the basic survival function. As long as human life contains real suffering, a lot of people will keep wanting something they can pray to.

Reproduction

Ask a lot of young couples why they’re not having kids, and you start hearing the same handful of answers. It’s too expensive. Housing is insane. Childcare costs more than rent. They finally have some freedom and don’t want to lose it. They want to travel. They’re exhausted already. The future feels unstable.

Some of that is pure economics. Some of it is culture. A modern, affluent society sells a particular version of the good life: autonomy, optionality, a clean schedule, a curated identity, and leisure that you can actually enjoy. Children compete directly with that package.

And then there’s the mismatch you don’t understand until you see it up close. People who don’t have kids often imagine parenthood as a permanent tax on money and time. People who do have kids talk about them like the center of gravity. You can chalk that up to bias and rationalization, and some of it is. But the pattern is still striking. The anticipated value looks low, and the experienced value is often enormous. That gap is hard to bridge with spreadsheets.

Religion bridges it in a straightforward way. It doesn’t only tell you that children are nice. It tells you that family is a duty, that life is a gift, that sacrifice is meaningful, that the future is something you owe to God and to your people. It wraps parenthood in status and honor and cosmic significance. You can see that in religious subcultures where large families are not treated as eccentric, but admirable.

Zooming out, it’s hard not to notice the broad correlation. Secular, wealthy societies tend to drift below replacement fertility, while more religious populations tend to have more children. The details matter and there are exceptions, but the direction is consistent enough to make you wonder whether religion is doing some of the reproductive work that modern incentives no longer do.

If “meme” means “a replicator that spreads because it helps itself spread,” then religion’s pro-family norms look less like a random quirk and more like the point.

Cohesion

Humans don’t survive alone. We survive by forming groups that can coordinate, share resources, punish defectors, and care for the sick. That requires trust and shared norms. It requires a sense that “we” means something.

Religion is unusually good at manufacturing that “we.” It creates a calendar, rituals, and shared language. It takes private morality and turns it into public expectation. It gives you a place to go every week where you are known. It binds strangers into obligations that feel older than any one person’s convenience.

You can call that social technology. You can call it myth. Either way, it produces cohesion. And cohesion is an advantage.

Conclusion

So my disagreement with Dawkins isn’t that religion can’t be irrational, oppressive, or destructive. It can. My disagreement is that he treats those failures as if they exhaust the explanation.

If religion persists, it’s probably because it has benefits that are easy to underestimate if you’re only measuring truth-claims. It helps some people stay alive. It helps some communities hold together. It helps some societies sustain family formation when the default incentives push the other way.

You can want a more humane, less coercive version of it. You can also want a secular substitute that does the same jobs. But if you try to rip the thing out without replacing the functions it served, you shouldn’t be surprised when the rest of the structure starts to wobble.
