No doubt a great importance in the paranormal field is the problem of fraud. The field of psychic research and spiritualism has been so notoriously full of charlatans, such as the Fox sisters and Eusapia Palladino–individuals who claim to have special power and gifts but who are actually conjurers who have hoodwinked scientists and the public as well–that we have to be especially cautious about claims made on their behalf.[61]

Senses used by mental mediums are sometimes defined differently from in other paranormal fields. A medium is said to have psychic abilities but not all psychics function as mediums. The term clairvoyance, for instance, may include seeing spirit and visions instilled by the spirit world. The Parapsychological Association defines "clairvoyance" as information derived directly from an external physical source.[37]
