remote viewing: This phenomenon first became a celebrated subject after parapsychologists Harold Puthoff and Russell Targ published a scientific paper which reported on experiments in which a remote location had been chosen, an experimenter visited there, and a subject recorded his or her psychic impressions of the spot. Their results seemed to prove that a “remote sensing” faculty did exist.
Subsequently, properly controlled tests were done by several other researchers, eliminating several sources of cuing and extraneous evidence that had been present in the tests. These new tests produced negative results. The data of Puthoff and Targ were reexamined by the other researchers, and it was found that their students were able to solve the locations without use of any psychic powers, using only the clues that had inadvertently been included in the Puthoff and Targ transcripts.
