LessWrong, more mess
My falling-out with the rationalist community
Nerd truth club accused of acting like just another squabbling belief tribe
TLDR: The writer says he fell out with the rationalist scene years ago, arguing that a group obsessed with being logical can still become smug and cultish. Commenters instantly split between defending it as unfairly smeared, mocking it as a secular religion, and cracking Timecube jokes.
A longtime internet skeptic turned critic has finally posted his breakup letter to the so-called rationalist world, saying he grew uneasy with it long before the splashy scandals involving Sam Bankman-Fried and the alleged Zizian cult drama. His bigger point: a group that sells itself as extra-logical and bias-busting can still turn smug, cruel, and weirdly sure of its own moral greatness. But in the comments, readers were far more interested in fighting over whether this was a brave expose or a cheap hit piece.
One camp rolled its eyes hard. User vovavili basically said, calm down: of course a community devoted to overcoming bias still has biases, and portraying a bunch of “well-intentioned and occasionally eccentric disagreeable online nerds” as something darker felt wildly unfair. Another commenter went even further, calling rationalism “just a secular religion” and dismissing the whole scene as not worth taking seriously. Ouch. Then came the spicy middle ground: some readers argued this sort of civil war is practically the community’s brand, comparing it to academia and old skeptic feuds where big egos explode over tiny points.
And yes, the jokes arrived right on cue. The funniest line of the thread may be the deadpan defense of Timecube: “Timecube.net will outlive any and all faddy Silicon Valley cults.” Meanwhile, one frustrated reader had the simplest complaint of all: the essay built up tons of drama, then seemed to stop just before delivering the full breakup gossip.
