I have called this type "low IQ" or lack of creativity, abandoning an important gift God instilled in man. They would even think that the Bible does not promote fiction, that Jesus' parables do not include use real names, in fact, some would even go as far as considering Jesus' parables as real history, real events that actually happened somewhere in time. To them, fiction = lie/false testimony and thus breaking biblical law. I don't know if they are honest with this belief or not. It may not have started honestly in the beginning but because they felt jealous for unable to keep up with the metaphors, they committed themselves into such shallowness to save their ego. My theory anyway.
I asked ChatGPT and this is the interesting answer I get:
There isn’t a widely recognized psychological term specifically for people who refuse to engage with fiction because it’s not real, but there are a few concepts that might explain their mindset:
- Literalism – Some people have a very literal way of thinking and struggle to see the value in things that aren't factual or real.
- Pragmatism Extremism – Some highly pragmatic people see fiction as a "waste of time" because it doesn't directly contribute to real-world knowledge or success.
- Reality Bias (or Hyperrealism) – A cognitive bias where people overly prioritize real-world experiences and dismiss anything that isn’t grounded in reality.
- Fictional Apathy – Not an official term, but could describe people who just don’t see the point of fiction because it doesn’t reflect real life.
- Neophilia Deficiency – A lack of interest in imaginative or novel ideas, preferring only tangible, real-world things.
Some might even argue it's a form of "fictional nihilism"—a belief that if something isn’t real, it has no value.
