I have been an amateur magician for over thirty years, member of the Society of American Magicians, the International Brotherhood of Magicians and a former Associate of the Magic Circle in London. I have studied mentalism and all forms of so-called ESP: it is merely trickery. A good reader can give a performance that will make his/her subject believe that their inner thoughts have been revealed, with information about a person’s past, present and, supposedly, future. Magicians have debunked mediums, seers and mind readers for ages. Houdini unmasked all the best mediums of his time. Before he died, he left a letter that said: if, after my death, a medium says that I am speaking from the beyond through him/her, if it is, indeed me talking, I will say the following words. Unless the medium says these words, he/she will be lying. Needless to say, no medium ever uttered those words (although his widow once tried to scam the public, but was found out…).
