Well, I can identify with that pattern. Though perhaps, i have been a lot slower at 29 with different levels of arrogance and shyness than you mention. But as far as i have noticed in others, it is not a very common trait. I have found that this trait does make us outside the normal distribution and my estimate* of the variance is around(2.5 sigma). *- Just a biased one from my past encounters and relationships and what i remember of them.
