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.[197][198]
Many 19th century mediums were discovered to be engaged in fraud.[64] While advocates of mediumship claim that their experiences are genuine, the Encyclopædia Britannica article on spiritualism notes in reference to a case in the 19th century that "...one by one, the Spiritualist mediums were discovered to be engaged in fraud, sometimes employing the techniques of stage magicians in their attempts to convince people of their clairvoyant powers." The article also notes that "the exposure of widespread fraud within the spiritualist movement severely damaged its reputation and pushed it to the fringes of society in the United States."[65]
In 1970 two psychical researchers investigated the direct-voice medium Leslie Flint and found that all the "spirit" voices in his séance sounded exactly like himself and attributed his mediumship to "second-rate ventriloquism".[173] The medium Arthur Ford died leaving specific instructions that all of his files should be burned. In 1971 after his death, psychical researchers discovered his files but instead of burning them they were examined and discovered to be filled with obituaries, newspaper articles and other information, which enabled Ford to research his séance sitters backgrounds.[174] https://drive.google.com/file/d/1zitTBgGddn7i6vwXjcjY-cBbhDhhupsW/view?usp=sharing
