I thought it was a scam. I knew someone who had completed the program so several of us went to her final event which was like a graduation. It was a real hard sell – they tried to persuade you that it started working when you gave them money. I was never intending to participate; I was just curious to see what it was. The tweet by Tom Nichols reminded me of it.
There was a fine parody in the film Semi-Tough.
