Main article: Parapsychology

Experimental investigation of the paranormal has been conducted by parapsychologists. Although parapsychology has its roots in earlier research, it began using the experimental approach in the 1930s under the direction of J. B. Rhine (1895 – 1980). Rhine popularized the now famous methodology of using card-guessing and dice-rolling experiments in a laboratory in the hopes of finding a statistical validation of extra-sensory perception.

In 1957, the Parapsychological Association was formed as the preeminent society for parapsychologists. In 1969, they became affiliated with the American Association for the Advancement of Science. That affiliation, along with a general openness to psychic and occult phenomena in the 1970s, led to a decade of increased parapsychological research. During this time, other notable organizations were also formed, including the Academy of Parapsychology and Medicine (1970), the Institute of Parascience (1971), the Academy of Religion and Psychical Research, the Institute for Noetic Sciences (1973), and the International Kirlian Research Association (1975). Each of these groups performed experiments on paranormal subjects to varying degrees. Parapsychological work was also conducted at the Stanford Research Institute during this time.

With the increase in parapsychological investigation, there came an increase in opposition to both the findings of parapsychologists and the granting of any formal recognition of the field. Criticisms of the field were focused in the founding of the Committee for the Scientific Investigation of Claims of the Paranormal (1976), now called the Committee for Skeptical Inquiry, and its periodical, Skeptical Inquirer.Eventually, more mainstream scientists became critical of parapsychology as an endeavor, and statements by the National Academies of Science and the National Science Foundation cast a pall on the claims of evidence for parapsychology. Today, many cite parapsychology as an example of a pseudoscience.

Though there are still some parapsychologists active today, interest and activity has waned considerably since the 1970s. To date there have been no experimental results that have gained wide acceptance in the scientific community as valid evidence of the paranormal.
