However often the airwaves wind up clotted with false memories and misidentified criminal culprits and folks dithering about what they recall, I still think a screw has come loose in our culture around notions of truth, a word you almost can’t set down without quotes around it anymore. Sometimes it strikes me that even when we know something’s true, it’s almost rude to say so, as if claiming a truth at all—what? threatens someone else’s experience? Most of all, no one wants to sound like some self-satisfied proselytizer everybody can pounce on and debunk.
