Ray Hyman (1928 - ) is a Professor Emeritus of Psychology at the University of Oregon in Eugene, Oregon, and a noted critic of parapsychology.
While attending Boston University as a young man, he also worked as a magician and mentalist, impressing the head of his department (among others) with his palmistry. Hyman at one point believed that 'reading' the lines on a person's palm could provide insights into their nature, but later discovered that the person's reaction to the reading had little to do with the actual lines on the palm. This led to his interest in psychology. He obtained a doctorate in psychology from Johns Hopkins University in 1953,
Aside from scholarly publications and consultations concerning psychic research, one of his most popular articles is thirteen points to help you "amaze your friends with your new found psychic powers!", a guide to cold reading. The guide exploits what fascinated him in his academic research in cognitive psychology, that much deception is self-deception. He has investigated dowsing in the United States and wrote a book on the subject.
