In my considerations about genius, I have over the years realized one of the pillars of brilliance is associative horizon (the other are intelligence and conscientiousness). To explain what I mean by this, here is a somewhat structured list of its suspected features: ………….
Partially personality-based, but don’t hold that against him. Rigidity of worldview.
Summarized, the person with wide associative horizon is primarily living one’s own mind, not letting one’s mental state be determined or strongly affected by others. This is not a choice but a personality feature outside of one’s control. Such a person may be seen as unusual, isolated, original, bizarre, detached from emotion, cold.
