From predictable to interesting, from left-brain to right-brain, from professional narrative to public narrative, from the tool value of resolving confusion to the emotional value of "unexpected and reasonable".

This involves a basic question, what kind of content mode is the most traffic-carrying and easy to spread? Harari has already given his answer in A Brief History of Mankind: Stories. On this point, researches in social psychology and communication have long concluded that there are two systems in the human brain, and facing a new problem, either use logic, data, information, probability in the left brain... …make judgments (professional narrative), or invoke the right brain into perceptual mode, captured by preconceived biases, assertions, emotions, images, experiences, intuitions, and stories (mass narrative). Unfortunately, people only use their text message service left brain in the areas of expertise they are proficient in, and in most cases they are right-brained animals. This is the reason why the stories are always unfavorable.
