John Albert, you certainly suffer fools a lot more gladly than I ever would. And you're to be commended for that, I guess.
You've already proven that the women in the magic doll routine was an actress. And that Derren Brown lied about it. And he is very much guilty there of the artistic repugnancy and laziness that he himself says that such a circumstance would be.
The magic doll case is open and shut. The larger question here, I think, is whether or not he is cheating the audience EVERY time he promotes a show with a "no actors or stooges" disclaimer, but then supposedly uses hypnosis to achieve the results.
Because regardless of whether or not the participants are professional actors, isn't the truly salient point whether or not they are, in fact, ACTING? Which is all that stage hypnotist subjects are doing. There is no such thing as a "hypnotic trance" that compels these people to do someone unconsciously, and against their will. They are simply going along for the ride, and role-playing.
