High fit

Anti-Alias controls whether you flatten things into clean binaries or allow for messy edges. Tristan Redmond had been running a sharp binary: either ghosts are real or they're not, and since they're not, nothing to see here. The accumulation of three families' stories forced him to move off that clean edge. He didn't switch to believing in ghosts — he moved into the gray area where he had to hold 'I don't know' instead of 'definitely no.'
