Can people move or alter physical objects simply by using a hidden power of the mind called psychokinesis? I have encountered many claims of such powers in the course of my work (since 1969) as a paranormal investigator. And I have pretended to have such ability myself—both as a professional stage magician and mentalist (a magician specializing in apparent psychic feats). In the fall of 2012, I attended a workshop that enabled me to investigate the latest popular expression of psychokinetic metal bending.
The term psychokinesis (formerly telekinesis), or PK, derives from the Greek words for “mind” and “motion.” Together with extrasensory perception (ESP), it constitutes what parapsychologists refer to as “psi” to describe the two seemingly closely related phenomena. However, the existence of psi has never been proven and, indeed, according to a sympathetic source: “Despite decades of research, psi continues to elude physical and quasi-physical theories of how it functions; it operates outside the bounds of time and space” (Guiley 1991, 468).
PK describes the alleged power of mind over matter, including such “micro-PK” acts as subtly influencing how thrown dice will land, or “macro-PK” feats like levitating a table or producing so-called “poltergeist” effects (actually, typically the tricks of children1). Psychokinetic metal bending is another alleged macro-PK phenomenon.
Geller the PK Marvel
It appears that the first major performer of apparent PK metal bending (PK-MB) was Israeli-born former fashion model and nightclub magician, Uri Geller (b. 1946) (Figure 1). Claiming to be guided by super beings from a distant planet, Geller appeared to read minds, bend keys and cutlery with PK, see while blindfolded, and perform other feats—all of which skilled magicians easily duplicate. (I, for example, have driven a car while blindfolded [Nickell with Fischer 1992, 77].) He typically refused to perform when magicians were observing but, nevertheless, was occasionally caught cheating.
Renowned American magician and psychic investigator James “The Amazing” Randi once observed Geller up close. Posing as an editor when Geller performed in the offices of Time magazine, Randi saw the simple tricks behind Geller’s wonderworking. For example, while Geller pretended to cover his eyes as a secretary made a simple drawing, he actually peeked, thus enabling him to appear to read her mind and reproduce the drawing. Again, while supposedly bending a key “by concentration,” Geller had instead bent it against a table when he thought he was unobserved. (For more on Geller’s methods, see Randi 1982.)
Geller was soon imitated by other “psychics” who discovered that they, too, could bend keys and spoons. One was Judy Knowles, who impressed London physics professor and parapsychologist John Hasted with her apparent ability. Hasted invited James Randi to observe tests of Knowles in a lab at Bath. Randi arrived with colleagues and his checkbook, offering Ms. Knowles $10,000 if she successfully passed the test, which was designed by Harry Collins of the University of Bath. Collins had tested other spoon benders, but none had been successful, and some children had been caught cheating.
Briefly, the test involved Knowles holding the spoon in a . . .
