The scientific community considers parapsychology a pseudoscience because it continues to explore the hypothesis that psychic abilities exist despite a century of experimental results that fail to conclusively demonstrate that hypothesis. A panel commissioned by the United States National Research Council to study paranormal claims concluded that "despite a 130-year record of scientific research on such matters, our committee could find no scientific justification for the existence of phenomena such as extrasensory perception, mental telepathy or ‘mind over matter’ exercises... Evaluation of a large body of the best available evidence simply does not support the contention that these phenomena exist."
