Nah, nothing that fabulously fancy and fantastically expensive. I'm simply talking about real basic, common sense stuff, really. Take "study tech" for example. I was raised in Catholic schools that used dictionaries, and used creative techniques of applying what you learned (much better than dinky demo kits). Had no idea how bad some public school systems had become in 21st century in U.S. until I applied for some community college courses.
I was appalled, really and truly. Then I learned that a) many students had been going through school drugged, one way or another and b) teaching methods were by rote "memorization".
as far as upper level "tech", taken from Crowley black majic and sci-fi writers like Heinlein, and Azimov, maybe.
The thing of it is, CornPie, it's just no that black and white. People have had genuine improvement in their life, and just because it happened in the midst of a hoax, doesn't mean you or anyone else can say they didn't experience it.
Talking to someone who you trust about a problem, or going to a music concert, or falling in love, or many things can help someone. And if those things happened while you were involved with something that didn't help, well, that might confuse the issue.
Hey, there comes a time when you have to decide who is holding reins of your life, but if it's someone else, you gotta know you can take them back. And then move on.
Anyone who falls for a ponzi scheme too can get a profit from it if they get out in time. That doesn't mean ponzi schemes are not a black and white issue.
