I'd take a counter point on this. The field of psychiatry found itself suddenly thrust into the realm of the legitimate during the popularization of utilizing many psychotropic drugs in attempt to balance perceived mental imbalances. The thing is, after years of attempting to objectively categorize many disorders which psychiatry fought so hard to correct, no one can find any correlational proof to the methodologies. In my eyes, the field of psychiatry (perhaps akin to chiropractic medicine) is fighting to remain legitimate in the face of surmounting scientific evidence that it is not.  ...and just to clarify, I guess my point is they're equal voodoo.
