Richard Feynman gave a commencement speech in 1974 and handed us a phrase we’ve been misusing ever since: cargo cult science. He described the Pacific islanders who, after the war, built runways out of bamboo, lit fires along them, and sat a man in a hut with wooden headphones and bamboo antennas — doing everything they had seen the Americans do to make planes full of cargo land. The form was perfect. The planes never came. They had reproduced the appearance of the thing without the substance of it.
Feynman’s point was about science: you can follow all the visible motions of research — the lab coat, the apparatus, the published paper — and still be doing nothing, if you’ve copied the form and missed the part that makes it work. But the phrase was always pointing at something bigger than bad science. It was pointing at us.
We are the cargo cult, not the cautionary tale
For fifty years “cargo cult” has been an insult you aim at other people’s sloppy work — their fake metrics, their theater of rigor. That usage quietly lets us off the hook. It frames the islanders as the fools and us as the ones who know the difference between form and substance.
But look at the actual structure of the islanders’ error, because it is not stupidity. They observed a real correlation: when the Americans performed certain rituals — manned the tower, wore the headphones, lit the strip — cargo arrived. They had no access to the causal mechanism (global logistics, war economies, aircraft), so they did the only rational thing available to a mind facing overwhelming results it cannot explain: they reproduced everything they could observe and hoped the result would follow. That is not a primitive error. That is the human error, the one we make every time we face a powerful process whose insides we cannot see.
The model is our bamboo tower
Here is the uncomfortable inversion. We now sit in front of a system that produces results we cannot explain through a process we cannot see, and we have started reproducing the forms that seem to summon good outputs: the prompt incantations, the ritual phrasings, the “let’s think step by step,” the settings we copy from each other without knowing why they help. We have built a folklore of gestures that seem to make the cargo land. Some of it works. Much of it is bamboo.
And at the higher level: the dashboards that perform oversight without exercising it, the “alignment” rituals that reproduce the appearance of safety, the evals we run because everyone runs them. Form reproduced in hope of substance. We are not laughing at the cargo cult from a safe distance. We are mid-ritual, headphones on, watching the sky.
Feynman’s phrase was never a museum piece about islanders. It was a mirror, and it has taken us fifty years and a sufficiently inscrutable machine to finally stand at the right angle to see ourselves in it. The cargo cult was always about us. We just needed something impressive enough that we’d start building the tower.
