Parapsychology is a research of paranormal and psychological events such as telepathy, precognition, clairvoyance, psychokinesis, near-death experiences, reincarnation, appearance, and other paranormal allegations. parapsychology A large bulk of conventional researchers regard it as pseudoscience.
Parapsychological study in several nations is mainly performed by personal organizations and financed through personal grants, and the topic is rarely covered in conventional scientific publications. In a few niche publications, the majority of articles about parapsychology are released. Parapsychology has been criticized for continued studies, although, after more than a decade of studies, it was not able to provide compelling proof that mental events exist.Parapsychology study
