I'm personally fascinated, even obsessive over learning about human brains and human thoughts and behavior in general, and find that most people (in general) S's, N's- whatever do not share the same passion. They are interested in hearing what I have to say, but that's the extent of it. Some people I talk to do enjoy the topic, but enjoy one aspect or theory over another. Most just don't care, it just doesn't interest some people, doesn't make them "s" or "less interesting." No conclusions here.
(Well I could be saying- the people who I do find are fascinated with it happen to be N's- when I actually had assumed that some of them were S's... When in reality it doesn't really matter, and I don't really know.)
I don't think that most of us, myself included, really understand the difference between the two, but we like to throw around grand conclusions like candy- (myself included again.)
