Paranormality by Richard Wiseman

Why We See What Isn't There

A skeptical, entertaining investigation into why people believe in ghosts, psychic powers, and other supernatural phenomena, combining clear explanations of psychological processes (suggestion, pattern-seeking, memory errors, and biases) with simple experiments, demonstrations, and a review of the research on paranormal claims; the book shows how ordinary perceptual and cognitive quirks, trickery, and statistical misunderstandings can create convincing experiences of the paranormal and offers practical ways to test and critically evaluate such claims.
