Exposed the Techniques Used by Faith Healers
The results of Randi's investigations into faith healers
Randi's most noteworthy experience was the unmasking of Peter Popoff, an evangelist who would call out the names of people in the audience and describe their ailments. Popoff said he received this information from God, but it was actually obtained by confederates who mingled with the audience before each performance. Pertinent data would be given to Popoff's wife, who would broadcast it from backstage to a tiny receiver in Popoff's ear. After recording one of Mrs. Popoff's radio transmissions, Randi exposed the deception on the Johnny Carson Show. First he played a videotape showing Popoff interacting with someone in the audience. Then he replayed the tape with Mrs. Popoff's voice audible to illustrate how Popoff used the information.
Randi also exposed the techniques used by evangelist W.V. Grant, who calls out people in the audience by name and describes their ailments. Grant obtains this information from letters people send him and by mingling with the audience before his show. To help his memory, he uses crib sheets and gets hand signals from associates who also use crib sheets. After one performance, Randi was able to retrieve a complete set from the trash Grant left behind! Following another performance, Randi found that some members of the audience had given false information about themselves, their ailments, and their medical care. For example, after "Dr. Jesus" had "put a new heart" into a man supposedly awaiting open-heart surgery, Randi found that the details (including the doctor and hospital named by Grant) could not be corroborated.
