Self Sorting

I know I need to read that book, The Big Sort: Why the Clustering of Like-Minded America Is Tearing Us Apart, but I have to mention that I was taking an online quiz, the type that's supposed to shed light on your mind in a way you've never thought of before but as a hyper-analytical person is ALWAYS disappointing, and I found myself thinking, "no one would ever answer that way, " over and over again. So I clicked on another one and another one and realized that I'm not just isolated from "differently minded persons", I have ceased to believe they exist.
When I attended school (particularly public school) and, to a certain extent, church, I was around people whose minds functioned differently from mine. There is some obvious self-sorting (or parental-sorting) when you attend a fundamentalist, literal, evangelical branch of Christianity church / private school. There were students who's nit-witted parents saw a cheap private school and thought *score* rather than a *big red flag*, but not that many.
As an adult my friends almost all fall into a broad category that I dare not define for fear of offending, but that leans dangerously toward music, books, politics, the social sciences, etc. I just hope I'm not missing out on tons of potentially bad-ass financial adviser, police officer, and number-cruncher friends out there.
