These details were from the falsified Facebook accounts for the pair which were prepared by a group of skeptics in advance of the reading, and Gerbic and Edward were not aware of the specific information in these accounts.[212] This blinding was done in order to avoid John later being able to claim he obtained the false information by reading Gerbic and Edward's minds.[209][210] In her report, Gerbic also revealed that during an after-show private event, John disclosed in a group setting that at least one of the people in the audience which he did a reading about was actually his own student.[213][209][210]

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]
