No, I don't know who they are.
I just want someone to do a breakdown of what he's likely doing. How he's doing it. Why they didn't find anything, etc. This is a massive diversion.
Well, fair enough. You seem to have run into a certain amount of perhaps unjustified flak. You have to make allowances, though; we have so many people coming here 'just asking questions'.
As to how he is doing it, we can't really know. We don't have to be able to explain his methods to dismiss the notion that it is paranormal, but one can always try.
For the 'electric' stuff: Alone the way he is touching people seems to rule out electricity. He only seems to touch them quite lightly and you get what appears to be muscle contractions.
Let me explain: The human body is the electrical equivalent of a saline solution. The resistance between any two parts of the body, when measured
inside the skin is about 300 Ohms. However, the
skin is not very conductive, and the resistance between any two points of the skin (by mere contact) is several thousand Ohms.
This means two things:
1) To create an impulse large enough to create a muscle contraction in another person, John Chang would have to create a many times stronger pulse in his own body, to overcome the attenuation when the high skin resistance is seen in series with the low internal body resistance.
2) Such a large pulse would dissipate most of its energy in the skin of the subject (and John's). This
hurts!. John Chang may be able to suppress his reaction, but the 'victim' would scream.
I think what he does (if the subject is not part of the trick) is to trigger one of the many involuntary reactions that exist (the knee-jerk reaction being the best known).
Of course, when he manipulates acupuncture needles, he is in contact with the inner body, but then when manipulating a needle deep in the victim's flesh, it is not difficult to elicit a reaction, even without using electricity.
The only tricks that may involve electricity is when he touches some other person and that person jerks his hand back, but even that may be done in other ways. As a trick, it could be done by giving himself a charge (like a static charge) and then zapping the other person, something we can all do under the right conditions.
As we know from certain creatures (think electric eels), a biological body can create quite a strong electrical current. This is done with converted muscle tissue. A considerable portion of the electric eel's body is devoted to this. None such converted tissue exists in the normal human body, however. I doubt that John Chang's body is any different.
Obviously, the ability to create an electric impulse would be extremely easy to test.
