dr. meltzer, i was listening to your presentation, and you mentioned something about in the '50s it was primarily the schizophrenic diagnosis was primarily for a white population. then all of a sudden, and you used the term out of the blue, it became something that was popularized for african-americans. and i'm wondering, i wasn't quite clear whether you were saying that when you say out of the blue whether it was they genuinely ignorantly started to make this misdiagnosis, or were they more like being dumb like a fox? in other words, needing a population that they could study, evaluate and do some different kinds of treatment with modalities? and my last part to the question is, is it coincidental that there were certain types of controversial therapies like shock therapy and, you know, in that sense that seemed to occur at the same time, and is there any connection. thank you. >> i'll just say very quickly because i know we're short on time that part of the point -- thank you, it's a terrific question. part of what i think we're all studying, i don't want people to leave or here and think like,
