In the late 19th century, the fraudulent methods of spirit photographers such as David Duguid and Edward Wyllie were revealed by psychical researchers. Hereward Carrington documented various methods (with diagrams) how the medium would manipulate the plates before, during, and after the séance to produce spirit forms. The ectoplasm materializations of the French medium Eva Carrière were exposed as fraudulent. The fake ectoplasm of Carrière was made of cut-out paper faces from newspapers and magazines on which fold marks could sometimes be seen from the photographs. Cut out faces that she used included Woodrow Wilson, King Ferdinand of Bulgaria, French president Raymond Poincaré and the actress Mona Delza. https://drive.google.com/file/d/1XI_lWChguCdGXwp7qEzW9MZ8-4-9Dz6F/view?usp=sharing
Magicians have a long history of exposing the fraudulent methods of mediumship. Early debunkers included Chung Ling Soo, Henry Evans and Julien Proskauer. Later magicians to reveal fraud were Joseph Dunninger, Harry Houdini and Joseph Rinn. Rose Mackenberg, a private investigator who worked with Houdini during the 1920s, was among the most prominent debunkers of psychic fraud during the mid-20th century. https://drive.google.com/file/d/16K4qFAF6q61QlZP1cN9QJhwSB3OgzOIw/view?usp=sharing
No doubt a great importance in the paranormal field is the problem of fraud. The field of psychic research and spiritualism has been so notoriously full of charlatans, such as the Fox sisters and Eusapia Palladino–individuals who claim to have special power and gifts but who are actually conjurers who have hoodwinked scientists and the public as well–that we have to be especially cautious about claims made on their behalf.
In 1958, the English-born Spiritualist C. Dorreen Phillips wrote of her experiences with a medium at Camp Chesterfield, Indiana: "In Rev. James Laughton's séances there are many Indians. They are very noisy and appear to have great power. [...] The little guides, or doorkeepers, are usually Indian boys and girls [who act] as messengers who help to locate the spirit friends who wish to speak with you."
On Fox News on the Geraldo at Large show, October 6, 2007, Geraldo Rivera and other investigators accused Schwartz as a fraud as he had overstepped his position as a university researcher by requesting over three million dollars from a bereaved father who had lost his son. Schwartz claimed to have contacted the spirit of a 25-year-old man in the bathroom of his parents house and it is alleged he attempted to charge the family 3.5 million dollars for his mediumship services. Schwartz responded saying that the allegations were set up to destroy his science credibility.
Knowing which questions to ask a psychic takes a little thought because the questions you think you want to ask will deliver little to no results. For example, passive questions like, "Will I ever get married?" "When will I meet my next boyfriend?" are impossible to answer because the future is not bound and determined. Instead, ask questions that can aid a current situation that could affect your life down the road - like marriage. A good example would be something like, "My partner and I seem to be hitting a wall. What are the most effective tactics for improving my relationship?" You also want to avoid questions that are begging for reassurance (Should I get divorced?) or that are full of doubt. Remember that standing up for yourself will get you farther than looking for a hand to hold. Instead, ask results-driven questions like, "Why am I no longer as connected with my partner now than when I was first married." The more precise you are with your questions, the better reading you will receive, so put a pen to paper before jumping on the phone.
In the late 1920s and early 1930s there were around one quarter of a million practising Spiritualists and some two thousand Spiritualist societies in the UK in addition to flourishing microcultures of platform mediumship and 'home circles'. Spiritualism continues to be practised, primarily through various denominational Spiritualist churches in the United States, Canada, Australia and the United Kingdom. In the United Kingdom, over 340 Spiritualist churches and centres open their doors to the public and free demonstrations of mediumship are regularly performed.
