Remember the lie detector test? Well the basis of that test is using physiological body reactions that cant be controlled by the conscious mind, the autonomic nervous system or the part of the nervous system that cant be controlled by the conscious mind, is an extremely useful tool. However, I think it has its limitations as it is not widely used because some people can be trained to fool the machine.
I think everyone to a certain degree, has the ability to detect subliminal changes in body language. So we can, tell, to a certain degree, how truthful someone is. Having said that, there are of course professional liars.
For most people who are used to only telling the truth, the moment we lie, there is some indication in our body language that we are not being honest. It takes a bit of training to consciously pick up these signals and I’d imagine this is what the book is talking about. I must get it and read it soon!
