The secret was probably the appearance of fiction. Large numbers of strangers can cooperate successfully by believing in common myths.
I am always weary of an idea that sounds good, and is presented like something that has been backed up by research and experts, but is really just the author’s opinion and has no sources to support it.
Also, I don’t like that he doesn’t differentiate between “fiction” and “myth”.
Myth attempts to explain a truth (or supposed truth) using a story that is not supposed to be taken as factual. Fiction is made primarily to entertain, not explain.
