The known techniques of TK involve trickery. The TK techniques that are genuine are not generally known, if they in fact exist at all.
There are important principles to succeed at such trickery. The more observant or more skeptical observers must be identified. TK tricks should then be attempted only when these people are distracted.
Methods of distracting them include luring a good cameraman away from the camera to be involved in the TK phenomenon directly. Keeping an eye on the skeptic until he turns away is another.
It is also desirable to enter into research tests conducted by natural scientists, not social scientists, since, while the former are schooled in avoiding self-deception, the latter are more versed in how to avoid deception by others.
A specific magic-trick type of technique is to palm a folded piece of paper, then, when all eyes are distracted, hurl it toward any electronic sensor meant to detect motion. The subject does not appear to have touched the sensor, yet the sensor mysteriously records that contact occurred. This trick can also be conducted successfully in front of video cameras.
A more concrete demonstration is the bending of keys and spoons. Since the audience detects no effort on the order of what is required to bend a key or break a spoon, it concludes only psychokinetic powers could be responsible. The trick is to bend the object when others aren't looking, then cover up the bent part of the object, perhaps revealing it only gradually, to give the illusion that the bending is going on right before the audience's eyes.
Consult a magician without the subject's knowing, to design the test of the psychokinetic's abilities. The aim is to reduce or eliminate access to the telekinetic claimant of certain known kinds of trickery. The removal of trickery may not be absolute, but the rate of trickery can be greatly reduced. Using a consulting magician to design TK tests is the strategy that Johnny Carson, himself a former magician, used in foiling a famous telekinetic guest on The Tonight Show.
So far, the answer seems to be "no." The Randi Prize is a $1,000,000 prize to be awarded to anyone who can demonstrate the existence of the paranormal. Because James Randi, a noted magician, is behind the prize, all comers have been unmasked.
One may argue that some subjects may exhibit less TK ability after tests are redesigned, but that they still exhibit the skills to a modest extent; therefore, TK must exist, and the deceit is only a tool to draw attention to a genuine ability. This argument would be more convincing if there was some point at which the ability could be designed away no further. But the whittling away at claimants' TK ability is asymptotic in nature--that is, it can be reduced to as small an amount as desired, by exerting enough patience and studying the tricks of the claimant enough to design the tests better and better. If there were some degree of TK ability that could not be designed away, no matter how much effort was applied, then the above argument for TK would have some credibility.
A genuine form of TK, used to allow the paralyzed to communicate, is the implantation of computer chips in the brain. Neurons overgrow the chip and learn to manipulate a cursor on a computer screen. The cursor response is slow and not close to the experience technologists hope such patients ultimately may have.
Such technology, though not technically TK, could arguably be called closer to TK than those who use magic tricks to give the illusion of TK.
