I wouldn't call it junk, actually. Used by itself it can be fairly shady, generalized or unreliable. But in conjunction with investigative processes it is useful. After all, it is regularly utilized with police investigations, FBI, etc. Certainly in interrogations.
I don't know. I saw a lot of other analyses saying exactly the opposite.
I think we all intuitively know, from body language, when someone is being deceptive. Trained investigators can become a bit more perceptive, but I'd expect there are maybe only about a handful of reliable red flags.
In the case of Ford and Kavanaugh, what I've seen with respect to body language has ventured into the unreliable and very subtle realms (a.k.a "junk"). It would be interesting to see a sample of Ford giving a lecture, to see what her normal tone and mannerisms are. I, too, thought her voice was oddly high pitched and baby-like, and saw some comments how a highly educated and accomplished, professional woman would not speak like that.
