This is a description of the Dunning-Kruger effect. While Dunning-Kruger is a popular topic around tech circles, I'm not so sure about the general population. I wish people weren't so ignorant about their own ignorance.
Edit: Adding clarity
People who have superior general knowledge have greater intellectual humility because they are more aware of their own ignorance and the complexities of the subject matter. Those who do not have superior knowledge are subject to the Dunning-Kruger effect.
Isn't it subjective when we consider the reality of the fish versus the reality of the human? Even among two humans the cornerstones of your psychic landscape can be vastly different. Are you talking about elemental reality? Any "elemental reality" that leaves out the vital elements of psyche, behavior, habit, preference, and perception would clearly omit a lot of vital information in coming to know Reality with a capital R.
