The main problem about this is that the author is basing his arguments on a show. A show written by writers who might even read the same pop-psych. Then he goes to reason from this show, into real-life. It's arguing from fictional evidence. If some of the actors behaves in a completely different way one week because there's a writer's strike or something, does it invalidate his theories?
IRL nobody behaves like people from The Show so any theory with this as the only basis is worthless.
