Vakava varoitus Ouija (spritismilaudasta, valolaudasta)

Itseasiassa on ja siinä ei ole mitään yliluonnollista.

"The Ouija (/ˈwiːdʒə/ WEE-jə, /-dʒi/ -⁠jee), also known as a 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, and it is moved about the board to spell out words. The name "Ouija" is a trademark of Hasbro[1] (inherited from Parker Brothers[citation needed]), but is often used generically to refer to any talking board.

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.

Various studies have been conducted, recreating the effects of the Ouija board in the lab and showing that, under laboratory conditions, the subjects were moving the planchette involuntarily.[16][21] A 2012 study found that when answering yes or no questions, Ouija use was significantly more accurate than guesswork, suggesting that it might draw on the unconscious mind.[17] Skeptics have described Ouija board users as "operators".[22] Some critics have noted that the messages ostensibly spelled out by spirits were similar to whatever was going through the minds of the subjects.[23] According to professor of neurology Terence Hines in his book Pseudoscience and the Paranormal.
Some involuntary movements are known as "Automatism".[25]

This correlates with the ideomotor phenomenon because both rely on unconscious movement. The difference is that the ideomotor phenomenon is based on the idea that just the idea that something can happen tricks the brain into doing it. For example, thinking about not moving the planchette leads to the possibility of the planchette moving, which then makes someone unconsciously move the planchette.[25]

Ouija boards were already criticized by scholars early on, being described in a 1927 journal as "'vestigial remains' of primitive belief-systems" and a con to part fools from their money.[26] Another 1921 journal described reports of Ouija board findings as 'half truths' and suggested that their inclusion in national newspapers at the time lowered the national discourse overall."
