A fake medium is likely to consider money first and foremost. Because a mediumistic reading is un-provable it's hard to get your money back. You know when something is wrong when nothing makes sense or the medium asks many probing questions. Remember however that even the best mediums have off days, but primarily things should make sense. Some pieces of information don't make sense for days, sometimes weeks after the reading. Realization comes though a family member or finding an old photograph or letter. A medium can never make promises about which spirits with come through or on what information they can gather from spirit. Contact doesn't work that way, and you tend to get what you're given!
In 1966 the son of Bishop Pike committed suicide. After his death, Pike contacted the British medium Ena Twigg for a series of séances and she claimed to have communicated with his son. Although Twigg denied formerly knowing anything about Pike and his son, the magician John Booth discovered that Twigg had already known information about the Pike family before the séances. Twigg had belonged to the same denomination of Bishop Pike, he had preached at a cathedral in Kent and she had known information about him and his deceased son from newspapers.[169]
In 1925, Samuel Soal claimed to have taken part in a series of séances with the medium Blanche Cooper who contacted the spirit of a soldier Gordon Davis and revealed the house that he had lived in. Researchers later discovered fraud as the séances had taken place in 1922, not 1925. The magician and paranormal investigator Bob Couttie revealed that Davis was alive, Soal lived close to him and had altered the records of the sittings after checking out the house. Soal's co-workers knew that he had fiddled the results but were kept quiet with threats of libel suits.[142]

I have been fortunate enough to work with trance mediums, one especially gifted one, in a therapeutic context for several years now. I personally feel we truly know next to nothing about the mechanisms behind trance channeling and mediumship. Like Edison said, "We don't know one millionth of one percent about anything." I do think it's far more likely to be an integrative both/and rather than either/or pheonomenon with respect to subconscious production vs spirit speakers (to say nothing of tapping the collective unconscious) and that's about all I feel reasonably sure of. Quantum (Unified Field)theories/New Paradigm Science and the like holds promise as far as cracking the code on the the entire spectrum of super-normal phenomena. The study here sounds rudimentary. I would suggest interested readers see the research being done at Windbridge Institue, the Rhine Research Center, and IONS.

For the less experienced mediums, exactly the opposite was observed--increased levels of activity in the same frontal areas during psychography compared to normal writing, and the difference was significant compared to the experienced mediums. What this probably means is that the less experienced mediums were trying really hard. The force is not yet strong with them.

In 1988, the magician Bob Couttie criticized the paranormal author Brian Inglis for deliberately ignoring evidence of fraud in mediumship. Couttie wrote Inglis had not familiarized himself with magician techniques.[178] In 1990 the researcher Gordon Stein discovered that the levitation photograph of the medium Carmine Mirabelli was fraudulent. The photograph was a trick as there were signs of chemical retouching under Mirabelli's feet. The retouching showed that Mirabelli was not levitating but was standing on a ladder which was erased from the photograph.[179]
I have read several book about mediumship, and currently reading surviving Death, Leslie Kean. I also have read time and again the skeptics crow every time they believe they have exposed fraud. The prance and buck at every attempt to make genuine controlled experiments, such as the Swartz experiments. They will never ever be convinced not ever, because for them the brain is the beginning and the end. Hell will freeze over before these critics would ever be anything other than convinced its all smoke, mirror, frauds and deceptions. Wikipedia-Not a good source for a complete treatment or fair treatment of any subject has several long and lengthy treatises discrediting anything suggestive of survival after the brain is dead.
The seven Glass family children have all been prodigies on the radio show "It's a Wise Child," but now the youngest, Franny, has returned from college to the family apartment in Manhattan and taken to her bed in a kind of nervous breakdown, sick of the world and unceasingly muttering a Jesus prayer. This is especially disconcerting because Franny and her next oldest brother, Zooey, are not only versed in all of the learning of the West, but have also been introduced to Eastern wisdom by their two oldest brothers, Seymour and Buddy. Salinger brings numerous key insights from Eastern wisdom into the heart of the American novel, and takes us on a spiritual journey in which the worth of all learning is called into question. Like Dostoevsky, Salinger risks everything. We discover with Franny that the answer she was looking for was right under her nose, and therefore close to her heart.
Humans have been fascinated with contacting the dead since the beginning of human existence. Cave paintings by indigenous Australians date back 28,000 years, some depicting skulls, bones, spirits and the afterlife.[3] Other cave paintings in Indonesia date back a further 10,000 years.[4] Mediumship gained popularity during the nineteenth century, when ouija boards were used by the upper classes as a source of entertainment. Investigations during this period revealed widespread fraud—with some practitioners employing techniques used by stage magicians—and the practice began to lose credibility.[5][6] Fraud is still rife in the medium/psychic industry, with cases of deception and trickery being discovered to this day.[7]
