A mail survey of 373 Ouija Board users has yielded some interesting though perhaps not unexpected results. Dr. John Palmer of the Rhine Research Center found that most users "claimed involuntary movements of the planchette and successful spirit communication." A full two-thirds of the respondents reported having a negative experience with the board, and around 50% said "they felt a compulsion to use it."
