My intention is to transmit, if possible, my assumption that we are motivated by assumptions we are unaware that we have. One way I sometimes try to do this is by mirroring the behaviors of people that are unaware of this, as I call it, fact. How we see the world is dependent on our understanding of how it works. Primitive man anthropomorphized the world attributing to it human feelings. Science came late to the game.
I took a real scientific theory, regarding the origin of the plague and made it sound ridiculous, as it does to folk without understanding by suggesting I invented out of thin air, just as those who do not understand how scientific theories originate and thus can't follow the reasoning. I wanted to show their stupidity by mirroring it, as if such a ridiculous idea could only be made up.
This is how the mind that is ignorant works. It can't see what people with deep study in a field can see. They do not have the knowledge base from which to make such connections. The gerbil thingi arose because scientists can't explain why the plague comes in cycles without some natural continuous reservoir of plague bacteria present in European mammals so they went out looking for some natural source. From there connections lead to burst and bust population cycles and what causes them, warm wet weather in the case of Asian Gerbils. The same kind of thinking goes into the Syrian thingi.
Understanding science requires a mind that is scientifically trained. Otherwise all one sees is Black Magic. Scientific thinking is a form of cognitive reasoning, the unconscious driver behind which is curiosity. It is a natural human thurst, that still kills a lot of cat children. Once bitten by unpleasant experiences with knowing, twice shy about the acquisition of new information. Sort of like being math phobic, maybe.
