Concerning Derren Brown's ethics - do I really need to be saying this?
Because James Randi is so heavily involved with scepticism, he tends to emphasise the 'it's just a trick folks' aspect.
When magicians perform their tricks, it isn't plausible to keep referring to the 'just a trick folks' and winking throughout the show in a knowing way and constantly reminding people that she/he has no psychic powers.
The lies, deception, concentration (as though building an inner power force) and misdirection which all magicians do as a necessary part of the show, IS 90% of the trick. Without a major part of most of these aspects, most tricks don't work. Yes I said lies and deception. They want to convince you to believe or see something that really is not there. I'm sure Mr Randi himself would (and I think has) confessed this openly.
Now the absolution (confession or justification for the foolery) is in the TV/show slot itself -an 'entertainment' show. MOST magicians do not tell the viewers before, during or after, that it was NOT psychic. David Blaine, David Copperfield, Kris Angel, Paul Daniels (an outspoken sceptic) even Penn and Teller sometimes I think. Do men go around reminding people that they are breathing, male, made of flesh? No. Why? It's a given.
Now Derren Brown is not only an outspoken sceptic, but he tells viewers at the beginning of EVERY show that he is not psychic and he even explains HOW he does what he does. He does not give a percentage of what is magic or deception or showmanship or misdirection or mentalism etc. I mean, he's just explained how, now give him a break and let him amaze viewers (using the very misdirection techniques and no psychic ability, just like he said). Are you expecting him at every stage to break it down? Some posters here seem to.
He even did a one hour special in the US (entitled 'Messiah') specifically decrying the gullibility of people generally and exposed 5 of the main biggest paranormal claims of today. He has worked with Dr Richard Wiseman - a former award winning magician turned psychologist and of couse a sceptic (known and well respected by Mr Randi by the way).
Another special called Seance exposed mediums. He's also duplicated Geller and other routines (apparently well convincingly) and also says he is not a psychic.
To those who accuse him of deceiving audiences, I feel you are not doing him justice. He does not have to justify himself or confom to any methodology that some viewers may prefer. Having said that, I know of no other magician who is so regular and clear in saying, in effect, that it is just a show. Independently, and without a need to, he is a great advocate of scepticism.
He is refreshing and puts a great slant on deception. If one magician direct/deceives you to believe he is using his mind to elevate a pack of cards rather than a piece of string and another magician has you believe that mentalism is the main aspect when it is a conjuring tick, it's a great idea.
At the end of the day, like all magicians, he deceives audiences like you and I, just as he claims he will at the start of the show. Not that this would make any difference, but I know James Randi is in contact with him and having corresponded with Mr Randi, I get the impression that he is a fan/supporter, but you might want to ask him yourself if you feel you need the permission or support of such a well respected man before endorsing him.
I have no axe to grind and I'm not working for Brown, I just feel (for the reasons I've stated) that this needed to be said. I hope this helps and that others will point unjustified negative proponents either to this E-Mail or watch him (again if needed) yourself.
