Is LSAT a method of reading body language?
No, LSAT is not directly related to body language. Body language teaches students to recognize deception in physiological responses such as pupil dilation, pore size, skin flush, muscle tone changes, breathing, etc. LSAT teaches how to recognize deception manifested in linguistic responses. The physiological and linguistic responses probably originate in the same place, but become outwardly recognizable in totally different places: one in bodily responses, the other in language. The benefit of LSAT over body language is that body language does not deal with information. While both can detect deception, only LSAT can reveal what the deception is because the reality behind their deception is revealed in their language.
