The other day I was browsing the TMZ website and they had a section that had pictures of celebrity couples being analyzed by a "body language expert". In essence, the guy was supposedly telling if these couples were really having a good time together or were just pretending for the cameras.
So I'm wondering how much can you really tell from a still picture rather than a short move clip? I feel highly suspicious on this one. I think it's like having a picture taken of you precisely when you're blinking and appear in the picture with a sleepy / stupid face.
Can there possibly be any validity to those analysis? Is there any branch of psychology that specializes in this sort of thing?
