Ouija boards

The Ouija ( WEE-jə, -⁠jee), also known as a Ouija board, spirit board, talking board, or witch board, is a flat board marked with the letters of the Latin alphabet, the numbers 0–9, the words "yes", "no", and occasionally "hello" and "goodbye", along with various symbols and graphics. It uses a planchette (a small heart-shaped piece of wood or plastic) as a movable indicator to spell out messages during a séance. Participants place their fingers on the planchette, which is moved about the board to spell words. The name "Ouija" is a trademark of Hasbro (inherited from Parker Brothers), but is often used generically to refer to any talking board. Spiritualists in the United States believed that the dead were able to contact the living, and reportedly used a talking board very similar to the modern Ouija board at their camps in Ohio during 1886 with the intent of enabling faster communication with spirits. Following its commercial patent by businessman Elijah Bond being passed on 10 February 1891, the Ouija board was regarded as an innocent parlor game unrelated to the occult until American spiritualist Pearl Curran popularized its use as a divining tool during World War I. Paranormal and supernatural beliefs associated with Ouija have been criticized by the scientific community and are characterized as pseudoscience. The action of the board can be most easily explained by unconscious movements of those controlling the pointer, a psychophysiological phenomenon known as the ideomotor effect. Catholicism and many Protestant Christian denominations have warned against the use of Ouija boards, considering their use in Satanic practices, while other religious groups hold that they can lead to demonic possession. Occultists, on the other hand, are divided on the issue, with some claiming it can be a tool for positive transformation, while others reiterate the warnings of many Christians and caution "inexperienced users" against it.
