Also, check who is telling you, are they reliable sources? Scholars on the issue? What is their basis for their believes? First hand knowledge or hearsay? If first hand knowledge, what proof do they have of it's supernatural effects? Be always critical, always ask questions, always know that if you believe somebody on just their word then most likely it will be easy for any moron to convince you of stuff without your researching it first. Look at who wrote the page, letter, website, book, etc. before you make your own conclusions based on evidence, not on emotion or fear.

Bottom line, from experience, Ouija boards are bullshit!
