I'm not especially impressed by most modern legitimate psychology.
But holy fuck is it hugely dangerous to start telling people that playing an RPG is the same as getting professional therapeutic help!
edited to add: in fact, pretty much any therapy that has "you're fine just the way you are" or "anything that's wrong with you is not your responsibility" is worse than useless, it's harmful.
I'm not sure, because I don't generally waste my time with games written by morons, but so far I don't know of any game that has gone quite that far. It's only a matter of time. Near as I can tell, we are still at the "Pretend that this session is a supplement to professional therapy." Which is at the stage of telling the GM and the players to engage in counter-productive behavior that is likely to set back any gains made from professional help, but is at least not pretending to be a complete substitute for it. Maybe I'm wrong, but I would think going that next step might open up someone to a lawsuit, or at least have a license board come down on them hard.
A professional told me that when dealing with trauma victims and the way their thinking can get twisted, it requires about 20 times of hearing the exact right thing to counter 1 time of hearing the exact wrong thing. A big part of
useful modern therapy is getting people to understand what they are responsible for and can fix versus what they can't do anything about, and thus must accept. Normal people, when a game or the GM tells them something exactly wrong, they sense at some level that it is off. Maybe has some nuance of truth badly expressed, but still off. Telling a trauma sufferer those kind of things in a game, billed as an adjunct to therapy, is basically ensuring that they will need to stay in therapy that much longer to reverse it. Running that kind of thing would basically be abusive.
