New Yorker longread on testing labs: grizzly bears as product testers and the philosophy of evals
Afinetheorem · x · 2026-10-23
Gideon Lewis-Krauss published a New Yorker longread on how testing laboratories work. The shared excerpt covers bear-resistant container certification: the Interagency Grizzly Bear Committee enlists real bears as product testers — containers must survive exactly sixty minutes of no-holds-barred "bear contact time" without holes larger than a quarter inch. Star tester Kobuk, nicknamed "the Destroyer," could defeat latches designed to defeat paws. The piece invokes roboticist Rodney Brooks' line that "the world is its own best model": no bear surrogate matches a real bear, yet humans must still define what counts as failure.
Circulating in AI circles, the piece reads as an implicit metaphor for how AI labs design evaluations — who sets the bar, and whether a product broken in the buzzer-beating fifty-ninth minute has failed.
