It Was You Who Made My Blue Eyes Blue

Fiction that dramatizes the classic 'blue eyes' common-knowledge puzzle. Five hyper-rational islanders (boosted by 'sparkroot') are stranded when a shipwrecked Spaniard announces that someone among them has blue eyes - triggering the induction whereby, on the nth day, n blue-eyed people who can deduce their own eye color must commit suicide. The story walks through mutual vs common knowledge, probabilistic-vs-certain knowledge, and assorted dodges, then lands a second twist: the islanders are all secretly atheists governed by the very same structure - each privately disbelieves the Volcano God, each knows the others do, but it was never common knowledge, so the shared pretense held. The outsider's announcement collapses both equilibria at once.

Quality 75 · Excellent. Conceptually dense and elegant - dramatizes the hard common-knowledge puzzle and ties it to preference falsification (a pretended religion that common knowledge detonates); a touch contrived, dialogue-as-lecture, and long. Strong. [RECAL 2026-06-19] 70->75, B30->42: ingenious conceptual fiction - dramatizes the blue-eyes common-knowledge puzzle AND lands a second common-knowledge payoff (the atheism / preference-falsification reveal); badly under-ranked at the band floor.

Claude’s paradigm shift 42 · Moderate. Every ingredient is well-established - the blue-eyes puzzle, common knowledge (Lewis/Aumann), preference falsification (Kuran); the pairing is a fresh synthesis, the ideas are not new. Slight.

Real-world impact 2 · Minor. Conceptually dense fiction that dramatizes the blue-eyes common-knowledge puzzle and ties it to preference falsification (a pretended religion that common knowledge detonates). Literary/conceptual reach within the rationalist-adjacent sphere, no material change — low RWI.

Humor 3/5 · Scissor Statement. Dramatization of the blue-eyed-islanders common-knowledge puzzle among hyper-rational cannibal-Goth Polynesians. Comedy is the defining voice: deadpan cannibalism-as-deterrent ('delicious with ketchup'), Enuli/Morticia's 'it's not a phase!' running gag, the Mersenne-prime/Fermat ritual laws, the 'I know you know I knew' romance parody, and the death-ray/take-over-Europe ending — sustained and lands, though woven through genuine puzzle-tension → 3.
