Religions Behave Like Memes, Not Revelations

If religions were divine revelations, we would expect them to behave one way. If they were cultural information packages — memes, in Richard Dawkins' original technical sense — we would expect them to behave another way. The actual behavior of religions in history matches the second model so precisely that the first becomes hard to defend. Religions mutate, split, compete, and propagate by mechanisms that have everything to do with cultural transmission and nothing to do with truth.

How Revelations Should Behave

A genuine revelation from a perfect being should:

  • Arise consistently across cultures, since the truth is one.
  • Resist mutation, since the original message is correct and any deviation is corruption.
  • Not need to be enforced, since its truth is self-authenticating to honest seekers.
  • Spread by the rational consent of those who examine it.
  • Converge over time as more people examine the evidence.

This is roughly how scientific knowledge behaves. The Pythagorean theorem is the same in every culture that has discovered it. The structure of DNA is the same in every laboratory that examines it. Where there is divergence, sustained inquiry produces convergence.

How Religions Actually Behave

Religions behave nothing like this. They behave like culturally transmitted information packages competing for human minds.

They mutate. Christianity began as a Jewish messianic sect, became a Greek-influenced gentile religion under Paul, mutated into the imperial church under Constantine, fragmented into Catholic and Orthodox, then into thousands of Protestant denominations. Each mutation is shaped by local political and cultural pressures, not by new revelation.

They split. Estimates put the number of distinct Christian denominations in the tens of thousands. Islam has Sunni, Shia, Ibadi, Ahmadiyya, and dozens of further subdivisions. Buddhism, Hinduism, Judaism — all show the same pattern of fission. If a single divine truth were the source, splits should be rare and resolvable. They are constant and irresolvable.

They compete. Religions actively struggle for adherents through missionary work, conquest, marriage rules (don't marry outside the faith), social pressure, and legal coercion. The mechanisms of competition are entirely earthly. A religion that fails to compete — that fails to recruit children, fails to marry within the group, fails to enforce social conformity — dies out. This is selection pressure, not revelation.

They are enforced. Almost every major religion has, at some point in its history, used violence and coercion to maintain itself. Heresy laws, blasphemy laws, apostasy laws, religious wars, inquisitions, forced conversions. If revelation were self-authenticating, none of this would be necessary. The need for enforcement is direct evidence that the message does not propagate on its own merits.

The Replication Mechanisms

Look at how religions actually propagate. The mechanisms are well understood:

  • Childhood indoctrination. Religions are imprinted on children before they can evaluate the claims. Almost no one converts as an adult to a religion they were not exposed to as a child. The "best" religious propagation strategy — the one practiced by every successful religion — is to capture young minds before critical faculties develop.
  • In-group rewards. Belonging to the religion provides social, economic, and psychological benefits. Membership grants access to community, marriage partners, business networks, emotional support, and meaning.
  • Out-group penalties. Leaving the religion is punished — by shunning, excommunication, family rupture, sometimes legal consequences or death. The cost of disbelief is artificially raised.
  • Memetic adaptations. Successful religions evolve features that aid their replication: hellfire to terrify defectors, evangelical commands to spread the faith, condemnation of doubt as sinful, prohibitions on intermarriage with outsiders, doctrines that make exit psychologically costly. These features have nothing to do with whether the religion is true; they have everything to do with whether it survives.

Notice that none of these mechanisms select for truth. They select for transmissibility. A religion that is false but well-adapted for transmission will dominate over a religion that is true but poorly adapted. We should therefore expect successful world religions to be optimized for spreading, not for accuracy. And that is what we observe.

The Family Tree of Religions

Religions can be organized into family trees that look strikingly like biological phylogenies. Christianity descends from Second Temple Judaism. Islam draws from both. Mormonism descends from American Christianity. Bahá'í descends from Shi'a Islam. Each branch shows clear inheritance from its parent, with modifications driven by the cultural and historical environment of the splitting moment.

This is the pattern of cultural evolution, not divine revelation. A revelation from a single God would not produce a phylogenetic tree of mutually contradictory faiths. It would produce a single tradition or, at most, regional variants of a coherent core. What we see is what we would expect from religions evolving like organisms in competing populations.

The "But Mine Is Different" Problem

Every believer agrees that the other religions are human inventions that propagate through these mechanisms. The Christian sees Islam as a culturally transmitted system. The Muslim sees Christianity the same way. The Hindu sees both. Atheists see all of them.

The question is whether you have a principled reason to exempt your own. The mechanisms that explain how Mormonism grew apply equally to early Christianity. The cultural transmission that produced Islam in 7th-century Arabia operated identically to the cultural transmission that produced rabbinic Judaism in late antiquity. There is no detectable difference in propagation mechanism between the religion you believe and the ones you reject.

If the same mechanisms that make those false religions spread are the mechanisms that made yours spread — and they are — then the spread of your religion is not evidence of its truth. It is evidence of its transmissibility, which is exactly what we'd expect either way.

Conclusion

Religions behave like memes — culturally transmitted information packages that compete, mutate, and propagate by mechanisms that select for replication, not for accuracy. Every feature of how religions actually exist in the world is consistent with this model. None of the features that would support the "divine revelation" model — convergence across cultures, resistance to mutation, propagation by rational examination — are present. We do not need to reach for the supernatural to explain religion. We need only to understand how cultural information evolves under selection pressure. The natural explanation is sufficient, and the natural explanation is what the evidence shows.
