He's wrong about how no colleges in the 1970's taught body language. In the late 70's I took a couple of Speech courses at a university. Neither one was about speech, per se. One was exclusively about body language, taught by an advertising firm executive, who knew how to read people and sell product based on their non-verbal responses. The other was taught by a Toastmaster (toastmasters.org) leader. He tended to focus on the "filter of the mind", how many people that hear the same things interpret them each based on personal experience and emotional state. Both were pretty great classes.
