In March 2017, medium Thomas John was targeted in a sting operation and caught doing a hot reading. The sting was planned and implemented by skeptical activist Susan Gerbic and mentalist Mark Edward. The unmarried couple attended John's show using aliases, and were "read" as a married couple Susanna and Mark Wilson by John. During the entire reading, John failed to determine the actual identities of Gerbic and Edward, or that they were being deceptive during his reading. All personal information he gave them matched what was on their falsified Facebook accounts, rather than being about their actual lives, and John pretended he was getting this information from Gerbic and Edward's supposedly dead—but actually nonexistent—relatives.[209][210]
In 1917, Edward Clodd analyzed the mediumship of the trance medium Gladys Osborne Leonard and came to the conclusion that Leonard had known her séance sitters before she had held the séances, and could have easily obtained such information by natural means.[119] The British psychiatrist Charles Arthur Mercier wrote in his book Spiritualism and Sir Oliver Lodge (1917) that Oliver Lodge had been duped into believing mediumship by trickery and his spiritualist views were based on assumptions and not scientific evidence.[120] https://drive.google.com/file/d/1Zh3T7RuksHd5otikwphwAW6hgGTlHjfr/view?usp=sharing
Today "demonstration of mediumship" is part of the church service at all churches affiliated with the National Spiritualist Association of Churches (NSAC) and the Spiritualists' National Union (SNU). Demonstration links to NSAC's Declaration of Principal #9. "We affirm that the precepts of Prophecy and Healing are Divine attributes proven through Mediumship."
Just as in any profession, mediums have specialties and areas of expertise. Unlike Allison Dubois in Medium, I don't work with the police in solving crimes. Or, unlike Melinda Gordon in The Ghost Whisperer, I don't help tormented souls cross over. Over the years, it has become very clear that my job lies in working with souls who have happily crossed over to the other side and, for the most part, are at peace. Sure, they may have regrets or unresolved issues, but they're not haunted or lost. Oftentimes, it's the living that are not at peace. The main goal of your deceased loved ones and spirit guides is to assist you in moving on, free of grief and struggle, so you can fulfill your life lessons and enjoy your time here on earth.
In a series of experiments holding fake séances, (Wiseman et al. 2003) paranormal believers and disbelievers were suggested by an actor that a table was levitating when, in fact, it remained stationary. After the seance, approximately one third of the participants incorrectly reported that the table had moved. The results showed a greater percentage of believers reporting that the table had moved. In another experiment the believers had also reported that a handbell had moved when it had remained stationary and expressed their belief that the fake séances contained genuine paranormal phenomena. The experiments strongly supported the notion that in the séance room, believers are more suggestible than disbelievers for suggestions that are consistent with their belief in paranormal phenomena.[51]

William Rauscher and Allen Spraggett, who attended a sitting Flint held in 1970 in New York, said that it was the most abysmal flop of any seance they had endured. All the spirit voices sounded exactly like the medium and displayed an incredible ignorance of nearly everything pertaining to the sitters. The "mediumship " was second-rate ventriloquism."

Psychologists and researchers who studied Pearl Curran's automatic writings in the 1930s came to the conclusion Patience Worth was a fictitious creation of Curran.[155][156] In 1931 George Valiantine was exposed as a fraud in the séance room as it was discovered that he produced fraudulent "spirit" fingerprints in wax. The "spirit" thumbprint that Valiantine claimed belonged to Arthur Conan Doyle was revealed to be the print of his big toe on his right foot. It was also revealed that Valiantine made some of the prints with his elbow.[157]
From its earliest beginnings to contemporary times, mediumship practices have had many instances of fraud and trickery.[55] Séances take place in darkness so the poor lighting conditions can become an easy opportunity for fraud. Physical mediumship that has been investigated by scientists has been discovered to be the result of deception and trickery.[56] Ectoplasm, a supposed paranormal substance, was revealed to have been made from cheesecloth, butter, muslin, and cloth. Mediums would also stick cut-out faces from magazines and newspapers onto cloth or on other props and use plastic dolls in their séances to pretend to their audiences spirits were contacting them.[57] Lewis Spence in his book An Encyclopaedia of Occultism (1960) wrote: https://drive.google.com/file/d/1rrXPtB9sGi67HwXA-JNbF6Z9qXtdSQX8/view?usp=sharing
Clairvoyance. Clairvoyant mediums can see spirits, auras, objects and places that are not perceptible to others. People who have passed away may appear to them in visions, or they may be able to vividly sense a place to which they have never been. Psychic mediums see these visions with their third eye, located between the two physical eyes. Everyone has a third eye, but the average person's is closed or too weak to use.

Mediumship became quite popular in the 19th-century United States and the United Kingdom after the rise of Spiritualism as a religious movement. Modern Spiritualism is said to date from practices and lectures of the Fox sisters in New York State in 1848. The trance mediums Paschal Beverly Randolph and Emma Hardinge Britten were among the most celebrated lecturers and authors on the subject in the mid-19th century. Allan Kardec coined the term Spiritism around 1860.[12] Kardec claimed that conversations with spirits by selected mediums were the basis of his The Spirits' Book and later, his five-book collection, Spiritist Codification.

What actually transpires during the trance is that the clairvoyant medium sees visions, hears voices, feels the energy and interprets his experiences in intelligible human language. The narration of the sequence of events is convincing as it divulges the secrets and facts, which are known only to the seeker. This revelation of personal facts builds trusts between the seeker and the clairvoyant medium.
A clairvoyant medium is a psychic who goes into trance, a sleep like state in which he allows his body and senses to be possessed by the spirit which may be his own guiding spirit or that of the seeker. The spirit has an overview of all the happenings on the earth. A clairvoyant medium can speak while lying down. He can also sit down or even walk and make gestures by moving his hands. He can even write or type his messages.
In 1936, the psychical researcher Nandor Fodor tested the Hungarian apport medium Lajos Pap in London and during the séance a dead snake appeared. Pap was searched and was found to be wearing a device under his robe, where he had hidden the snake.[160] A photograph taken at a séance in 1937 in London shows the medium Colin Evans "levitating" in mid air. He claimed that spirits had lifted him. Evans was later discovered to be a fraud as a cord leading from a device in his hand has indicated that it was himself who triggered the flash-photograph and that all he had done was jump from his chair into the air and pretend he had levitated.[161]
During the séance or trance period, note that as a medium you should not ask too many questions of the person you are helping. A good medium never asks the client to tell them the name of the deceased or any details; otherwise, it is not a valid reading. It is up to you to validate the deceased loved one's name, occupation in life, birth date, physical description, how they passed, and so on.
The article about this phenomenon in Encyclopædia Britannica places emphasis that "… one by one spiritual mediums were convicted of fraud, sometimes using the tricks borrowed from scenic "magicians" to convince their paranormal abilities". In the article it is also noted that "… the opening of the wide ranging fraud happening on spiritualistic sessions caused serious damage to reputation of the movement of a Spiritualism and in the USA pushed it on the public periphery".[208]
In the later half of the 20th century, Western mediumship developed in two different ways. One type involved clairaudience or sensitives who hear spirit, and then relay what they hear to their clients.[29] The other incarnation of non-physical mediumship is a form of channeling in which the channeler goes into a trance, or "leaves their body", allowing a spirit entity to borrow their body, who then speaks through them.[30] When in a trance the medium appears to come under the control of the spirit of a departed soul, sometimes entering into a cataleptic state,[31] although modern channelers may not.[citation needed] Some channelers open the eyes when channeling, and remain able to walk and behave normally. The rhythm and the intonation of the voice may also change completely.
