I studied non-verbal communication in college, have a psych minor, have worked in psych for many years and in life. The show depends on research and I would think they have an expert on hand when writing the show.

The one show I saw where the main guy couldn't get a read on a female judge and then it was decided to be impossible due to the judge having had botox injections in her forehead. Do you mean to tell me an expert, couldn't read anything else on the judge? I stopped watching after that.

It reminds me of the hospital shows...that stuff just doesn't happen like that. Make a show about the medication errors of doctors and nurses and you've got a likely scenario as no scene; no matter how ridiculous, dangerous or unbelievable has happened somewhere before.
