I think a distinction between physical characteristics and body language is important. I do think body language affects opinions of people. I have known a number of people who are not attractive by much of any standard but their body language is so positive that people are drawn to them. It isn’t hard to tell a sincere smile from a fake one. This article is about body language not beauty whether one accepts his opinion of Cruz or not.
Fair enough, but I still think it is psycho-babble.
