There might be a little more evidence for these effects than you are crediting.
Sometimes it’s true that when something happens to one entity, the same thing happens to others that are closely related. Get one person sick, and his whole tribe may become sick. Make a person sad, and his lover will (after they have been together for a while) become sad too. Maybe enough examples of this kind of thing led to over-generalizing.

It is noteworthy that your examples involve human beings and their responses directly. Very noteworthy.
This idea will be explored further in the next post.
