You probably know the type. Maybe you’ve been the type. Someone who discovered a framework for thinking clearly, felt the thrill of finally seeing through the noise, and thought: this is different. These people get it. We get it.
That’s exactly how I felt about the rationalist community.
Here was a group that explicitly set out to overcome cognitive biases, that warned against tribalism, that treated clear thinking as a moral obligation. For a while, it felt like finding water in a desert of bad takes and motivated reasoning.
Then I watched the same community fracture into factions, enforce orthodoxies, excommunicate heretics, and rally around personalities with a fervor that would make a megachurch pastor blush.
Rationality doesn’t make you immune to being human. It just gives you a more elaborate vocabulary for your biases.
Let me be specific. The rationalist community has sacred texts — the LessWrong sequences, dense and sprawling, treated with a reverence that borders on scriptural. It has high priests. Eliezer Yudkowsky isn’t just a thinker in this world; he’s a prophet whose pronouncements ripple through the community like papal encyclicals. It has heresies — positions that get you quietly frozen out. It has schisms over doctrinal points so fine you’d need a microscope to see the difference, yet they generate more heat than most political arguments.
If you’ve ever watched a church split over worship music style, you understand the mechanism. The content changes. The pattern doesn’t.
Here’s what’s painful about this. The people involved are genuinely smart. Many of them are trying, in good faith, to think better. But intelligence is not a vaccine against social dynamics. If anything, it makes the infection harder to detect, because every tribal impulse gets dressed up in rigorous-sounding language.
You can’t reason your way out of being a primate. You can only build better institutions that account for it — and the rationalists never built those institutions.
I saw this firsthand. Disagreements that should have been intellectual exercises became status contests. People who preached the importance of updating on new evidence clung to positions long after the evidence turned against them — because retreating meant losing face. The community’s explicit commitment to truth-seeking existed in permanent tension with its implicit commitment to belonging.
And belonging always wins. It always wins.
This isn’t unique to rationalists. The skeptic movement went through the same cycle. Objectivism before that. Every group that claims to have transcended ordinary human folly discovers, eventually, that it hasn’t. The naming changes. The pattern is ancient.
Any movement that defines itself by being smarter than everyone else has already taken the first step toward becoming a cult. The only question is how far it walks down that road.
The twist I didn’t see coming: the problem isn’t that rationalism failed. The problem is that it succeeded at exactly what it was actually designed to do — create a sense of superiority and belonging for a specific kind of person. The truth-seeking was always partly real, partly branding. When the two came into conflict, branding won. It always does, because branding is social and truth-seeking is solitary, and humans are not solitary creatures.
So where does that leave those of us who actually want to think clearly?
Alone, mostly. Or in small, unglamorous groups that don’t have a name, don’t have a founder, don’t have a manifesto, and therefore don’t have anything to be tribal about. The moment you build an identity around being rational, you’ve created the conditions for irrationality to flourish under its flag.
The clearest thinkers I know don’t belong to any thinking community. They read widely, argue in good faith with whoever shows up, and change their minds without announcing it.
I’m not saying communities are worthless. I’m saying that the moment a community becomes an identity, it becomes a liability. Hold your frameworks loosely. Trust people who disagree with you and still show up. Be suspicious of any group that makes you feel smarter than outsiders — that feeling is the drug, and the hangover is coming.
The rationalists taught me a lot of useful concepts. They also taught me, unintentionally, the most important lesson of all: no framework survives contact with human nature unchanged. The map is not the territory. And the territory is always, always more human than you expected.
FAQ
Q: Isn't this just cherry-picking the worst parts of a well-intentioned community?
A: No. The point isn't that individual rationalists are bad actors. It's that the community's structural dynamics — identity, status, belonging — predictably produce the same tribal outcomes as any other group. Smart people in a smart community doesn't immunize against human nature. It just makes the biases harder to spot because they're wrapped in sophisticated language.
Q: So should I just avoid any intellectual community entirely?
A: Not necessarily. But you should avoid making any community your identity. The moment 'I'm a rationalist' or 'I'm a part of X' becomes part of how you see yourself, you've created a psychological incentive to defend the group. Use frameworks. Learn from communities. But hold your membership loosely enough that you can walk away when the group starts prioritizing belonging over truth.
Q: Isn't calling rationalism a 'religion' just a cheap rhetorical shot?
A: It's an observation, not an insult. Religions persist because they solve real human problems: meaning, belonging, identity, moral framework. Rationalism solves the same problems for a specific demographic that won't admit it needs them. The denial is what makes it dangerous — a church knows it's a church. A movement that thinks it's above social dynamics is the most vulnerable to them.
