Depressed people are found to be more rational than the people who feel successful This sounds to me like you took something wildly out of context. For example, is a depressed person more rational than someone who just won a hand of Blackjack? Probably. Is a depressed person more rational than the same person when not depressed? As someone who is currently helping a friend through a very bad bout of depression, I can say with confidence that the answer is no. Doctors don't even know why these drugs work. I know a lot of programmers who don't know how a transistor works. Does this invalidate their work?
