Pronoia

 Pronoia: At one point in J.D. Salinger’s Raise High the Roof Beam, Carpenters, Seymour Glass muses about himself, “Oh, God, if I’m anything by a clinical name, I’m a kind of paranoiac in reverse. I suspect people of plotting to make me happy.” About three decades later, sociologist Fred Goldner came up with a name for this: pronoia, the opposite of paranoia. Instead of the fear that you are at the center of some diabolical lot, pronoia, as Smith describes it, is the “strange, creeping feeling that everyone’s out to help you.” And, hey, just because you’re pronoid doesn’t mean they’re not out to help you.
