Diversity of belief among organized spiritualists has led to a few schisms, the most notable occurring in the U.K. in 1957 between those who held the movement to be a religion sui generis (of its own with unique characteristics), and a minority who held it to be a denomination within Christianity. In the United States, this distinction can be seen between the less Christian organization, the National Spiritualist Association of Churches, and the more Christian spiritual church movement.
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."
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.
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. 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.
Do compose your emotions and appearance to hide any revealing information about yourself. Your facial expression, style of dress, personal mannerisms, and emotional outbursts can tell a psychic, especially a false one, a great deal about you to make it look like she knows all these things from a paranormal reading, when in fact, she is merely interpreting your physical appearance or reactions.
