People who themselves are not attracted to STEM trying to understand the minds of people who are strong in STEM. I am getting the idea that many people who are strong in STEM are not thinking in a verbal manner, but using a kind of visual mode of thinking, being able to create complex structures in their mind without having to rely on words. This modes of thinking are not based on 'if', 'and', and 'then' lines of verbal reasoning. (It has long been an opinion that thinking and reasoning cannot be done without language, which of course is not true.)
I can totally relate. The first thing I do when I enter into a new technical or mathy topic is to build the intuition for those concepts, which simply means finding a way to visualize them without words. Then it's much easier to think about them.
