Parapsychology is the study of paranormal phenomena such as telepathy, precognition, and psychokinesis. It originated in the late 19th century with organizations like the Society for Psychical Research founded to critically investigate these claims. In the early 20th century, J.B. Rhine conducted early laboratory research at Duke University. While some research continued in the 1970s-80s, parapsychology faces strong skepticism from the scientific community and replication issues. Critics argue apparent positive findings likely result from methodological flaws rather than genuine psychic effects.
