Do psychic abilities actually exist? This is still a controversial issue within the scientific community. In recent years, there has been an increase of support amongst scientists and academics. Parapsychologists have scientifically studied psychic abilities for more than a century. Many scientists now claim that belief in psychic abilities may be scientifically plausible. For example, parapsychologist Dean Radin of the Institute of Noetic Sciences, claims that psychokinetic alteration of the output of random number generators is scientifically well-founded.
