Please permit me to point out that your characterizing the statement "I'm reading micro-expressions..." as being a "plausibility," is a bit off the mark.
If you garnered your knowledge from the Tim Roth television program (I don't have a TV, but confess I do catch the occasional re-run on HULU), your thought is understandable. The episode I saw expressed the same misconception.
Ray Birdwhissel could probably be called the first serious investigator of body "reading," with his published studies in "Kinesics." HIs work helped launch the careers of many so-called "body language experts."
Paul Eckman can clearly be called the world's leading exponent on the topic. His studies of facial expression, nervous tics, body positioning and the like, are the seminal works in the field.
Your mention of reading a micro-expression, however, is misinformed. A micro-expression is called what it's called because (the micro part) is NOT visible to the naked eye. It's only seen in slow-motion video capture. So, unless you meant to imply that you were reading what you saw on a television screen or computer monitor, your surmise was incorrect.
The only real mentalist I can think of who actually employs such knowledge is Marc Salem, who was, before going full-time as a very successful performer, a professor of psychology, and a student of Mr. Birdwhissel.
Hope this helps. I haven't looked at the site, but just in case (and I'll gain the ire of several folks by saying this), there is NO empirical evidence which suggests the claims made by NLP "authorities" are in fact, reality. NLP is (was, actually) a fascinating series of conjecture regarding the unconscious mind, and how it could be successfully accessed through esoteric communication theories. It turned out, however, that in real world application, the theories were nothing but theories.
I first encountered NLP when a staff member at a (then new) psychiatric facility (I later switched to trauma, which I found to be more interesting, then dropped out of the field altogether). I read all the works published I could find on the subject then, participated in some of the "exercises" developed based upon the theories postulated by the gentlemen who "discovered" the NLP process. I even encountered one of the original guys when attending a conference on hypnosis (which IS "real," by the way), but a rose by another name, when applied by folks like Kreskin - a guy I found fascinating as a kid - for a variety of reasons, I suppose he still is. He remains one of my favorite performers.
As I've not seen your site (and as it appears to be a commercial?), I probably won't, but mentalism and hypnosis, used by an entertainer (and, to some small degree, even by a therapist) can be very effective. The two fields are a natural mix. Look up the literature on Franz Polgar, who was, I believe, the first to regularly employ both together. It's possible Kreskin developed much of his work on that of Polgar.
