I can guarantee if those people had been honest and said there was only a 60% chance they would know what they were doing = I would have walked out and saved myself a great deal of frustration. There are studies that put the failure much higher -plus those guys do not study their failure/harm rate nearly enough. The therapists were not on my side - I did not go in with sides. All I ever wanted to know was how did it work and what was supposed to be going on.
