The second set of audience this would appeal to are people with autism. Sitcoms have always done this. Some people really need to be told when to laugh and what people are thinking because they have no ability to read body language, zero empathy, and cannot read the room. Once you encounter it regularly it’s mind blowing and that a significant portion of the population commonly lives with this sort of mental blindness.
As for empathy, it too varies from person to person. It is possible, though unlikely, to score high in empathy and yet utterly fail all the rest of the performance criteria. One of my coworkers with autistic children may or may not have autism themselves but does demonstrate high empathy.
In my experience people with autism tend to score remarkably low in empathy with some people even having absolutely no empathy at all. That is why many people with autism seem socially weird or have trouble reading a room. For people with high empathy these observations of low empathy in others is most obvious potential indicator of autism.
While very few people score high in empathy it’s equally rare to absolutely have no empathy at all. It is such a striking disadvantage as to be a major disorder. It is severe enough that it looks like sociopathy minus an informed intent. It’s a processing void. That void is further obviated by an equally diminished introspective capability in that reading one’s self is the same skill as reading others.
Also, empathy is not in any way related the quantity of emotions people display. A person can be both selfish and highly emotional.
