According to professor of neurology Terence Hines in his book "Pseudoscience and the Paranormal" (2003):  The planchette is guided by unconscious muscular exertions like those responsible for table movement. Nonetheless, in both cases, the illusion that the object (table or planchette) is moving under its own control is often extremely powerful and sufficient to convince many people that spirits are truly at work ... The unconscious muscle movements responsible for the moving tables and Ouija board phenomena seen at seances are examples of a class of phenomena due to what psychologists call a dissociative state. A dissociative state is one in which consciousness is somehow divided or cut off from some aspects of the individual's normal cognitive, motor, or sensory functions. 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. 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. In the 1970s ouija board users were also described as "cult members" by sociologists, though this was severely scrutinised in the field. Since early in the Ouija board's history, it has been criticized by several Christian denominations. For example, "Catholic Answers", a Roman Catholic Christian apologetics organization, states that "The Ouija board is far from harmless, as it is a form of divination (seeking information from supernatural sources)." Moreover, Catholic Christian bishops in Micronesia called for the boards to be banned and warned congregations that they were talking to demons when using Ouija boards. In a pastoral letter, The Dutch Reformed Churches encouraged its communicants to avoid Ouija boards, as it is a practice "related to the occult". The Wisconsin Evangelical Lutheran Synod also forbids its faithful from using Ouija boards as it teaches that such would be a violation of the Ten Commandments. In 2001, Ouija boards were burned in Alamogordo, New Mexico, by fundamentalist groups alongside "Harry Potter" books as "symbols of witchcraft." Religious criticism has also expressed beliefs that the Ouija board reveals information which should only be in God's hands, and thus it is a tool of Satan. A spokesperson for Human Life International described the boards as a portal to talk to spirits and called for Hasbro to be prohibited from marketing them.
