I'd be very curious to see how causation may be found for most psychological conditions. I'm sure there are ways I haven't seen or considered, but it seems really difficult to structure a study that would lead towards potential causation.
Traumatic brain injuries are one standout, though even then I think its just correlative as no one is going to attempt a study that intentionally causes TBIs in the test group.
