There's a term I'm drawing a blank on just now that refers to one's tendency/ability to think of things as separable. It's something like high vs. low segmentation/delineation/compartmentalisation/discretion individuals. For some people, different aspects of a person/concept/etc. can be more readily separated in their consideration. For others, the associations are too strong to be ignored.
Some people have low (word I am having trouble remembering). These are people who cannot or have difficulty in separating different elements of consideration. These are people who say the only way to understand, say, The Lord of the Rings is to understand Tolkien, or that one cannot separate the mysogyny of Tomas from the music of Nightwish. They are also the kind of person who, if they met Ted Bundy in the office, would then have great difficulty reconciling that friendly experience with new information saying he was a murderer.
Some people are high (word). They split concepts frequently and easily. These are people who can look at things which are connected by being parts of the same whole but consider each part separately, like say, looking at the beliefs of Ted Kaczynski and saying he was right about this one technology but wrong about bombing as the optimal solution, or that it's wrong to murder but eating the dead is fine. These are also the kind of people who are more capable of meeting someone, being their friend for years, trusting them, but still having the cognitive distance to see the evidence in front of them and realise their friend is abusing his daughter, even if that doesn't comport with how they have previously seen that friend.
Each way of thinking is as alien to the opposing end of the spectrum as introverts vs extroverts or the religious vs materialists.
