i think the biggest factor by far is that Ns tend to associate themselves with other Ns. my first high school group of friends was 7 people, all Ns. my 2nd group was 8 people, and only 1 S. but my classes were mostly S types...
and i didn't know about mbti in high school.
it seems that all of my deep, meaningful relationships are always with Ns. i can get along great with S types, but i often hold back from talking because i can see it on their face that they think what i'm saying is worthless.
