I think one of the things which can damage a sceptics authority on this debate is the lack of acknowledgment as to how clever some of these fraudsters can be. Often a sceptics explanation as to how fraudsters are reading is very simplistic and unsophisticated. This leads believers to dismiss what theyre saying because its unrealistic- whereas if sceptics could be a little more well, respectful (not the right word, as why would why want to respect them) for the level of manipulation and complexity that goes into the deception, acknowledging that in some cases it really is very smart, I think the debate would be richer and it would more than likely help the sceptics argument.
Of course you can get the cheap, nasty and crap fraudsters who just throw out a load of crap and hope some sticks, but for the really good ones, it is FAR more complex and its very likely most sceptics have no idea how theyre doing it. For example, going back to James Randi, one of the biggest fraudsters he exposed was a healer guy. It was a long time ago (in the 70s I think) but this guy was a multi millionaire from his healing, filling entire stadiums with paying customers.
James Randi knew he couldnt heal people, couldnt use his gift to diagnose them (he would tell complete strangers I know youve come here because you have parkinsons. After a little ceremony the parkinsons was cured. Not only was he not told by the participant what illness they had, but they believed themselves healed. So 2 types of deception I guess) BUT Randi, a magician who had spent his life exposing frauds, didnt know how he was doing it. It took years, a undercover operation infiltrating the guys staff and bugging the sound system etc. before they discovered he was being fed information through an ear piece.
Granted, it was some time ago. But if Randi didnt know then, how can all these posters claim to know how people do it now just from watching a few Darren browns? The simplification of what is a complex issue is also partly to blame for people continuing to believe IMO.
Incidentally Sally Morgan was caught using the same ear piece process a good 40 years later. Shows how smart she is, LOL. Shes one of the ones who is easy to work out
