I mean, sure, you get the occasional Ted Kaczynski, but the vast majority of kids I've heard of entering college early seem well-adjusted.
Occasional? Ted was one of a kind. And apparently, you don't "get" someone like him. Allegedly, rather, you "make" that kind of person through government sponsored psychological torture experiments. http://www.theatlantic.com/magazine/archive/2000/06/harvard-...
That's, unfortunately, who a lot of people automatically jump to when they think of "maladjusted precocious children/young adults" I think there was a RadioLab episode about him as well?
My younger sister was regularly mistaken for a teacher when she was in 7th grade.
I was pretty obviously an immature punk all through high school, but some people are both academically and socially advanced.
Right now, my five year old son with autism is simultaneously learning the toilet and calculus. Who knows where he'll be socially when he's academically ready for college?
