(Anyone ever wanted to know how an INTJ REALLY thinks...there you go. )
There are some people that it's a pleasure to argue with, because they're both smart enough to know I'm smarter AND they know as much or more than I do on a given topic, OR they're as smart as or smarter than me. (Two of my grad school professors are highly likely to have had much higher IQs than me--notably, I dress more nicely and smell FAR better than they did )
Now, THERE'S some INTJ arrogance for you.
Guess what I've learned? People don't like it when you treat them like idiots when you deign to notice their presence, and they CERTAINLY don't like being ignored. Here's the problem: a great deal of my life is determined by people not under my immediate control. My employer, my doctor, my family, my friends, my landlord, my barista---these people control whether or not I have money, health, Christmas presents (yay!), people who love me, a place to live, and more importantly than anything else: my morning coffee.
