Well, I am somewhere in the middle of seven brothers and my father and mother.
Father = ESTJ
Mother = IxFJ
three of my brothers are NT. We have ENTJ, INTJ, INTP. These guys and my father are the only T types in the family. Everyone else is a huge ass NF or SF. anyway.
Focusing on the NT guys, they always act super indipendent like they don't care what anyone thinks of them. They pretend that they are immune to all the mind shifting irrationality of us lesser mortals. They are arrogant inside their heads and really do think they are somewhat superior to others, you know the holier than thou attitude.
They pretend to be evil and uncaring, but this is the farthest from the truth.
Basically, I just see a whole smoke cloud of bad assitude, when really deep down inside they are nothing but super nice caring human beings.
No offense to INTJ's, this is just a personal account of my brother, he is probably my closest friend that manages to piss me off to no means with his stubborness and self sense of being superior to most. Back in high school, he used to tell me how he didn't care what anyone would think and wouldn't hesitate to mess some one up and blah blah blah. When some kid came and started ruffing him up once, he just froze, I watched for a second or two, because I really believed my big brother was the bad ass he claimed to be, but he just was frozen in terror. My brother gave a snide remark (something about not waisting his time with trash) and started walking away. I could see right through it that he was terrified, so I had to run in and blind side this goliath of a moron that was messing with my brother. When brother saw us both on the floor, he came back and started stomping the dude with so much hate, I had to stop him...
Well that was a shitty story from back when I was a kid, but this is when I personally realized that guys like my brother who seem to be badass are no different than everyone else in their fears, arrogance, and emotions. The only difference between people, was the attittude in which they chose to present themeselves. This was a while back when I was 16 and had no clue what MBTI was though.
I guess what I am trying to hit at, is that my personal experience with NT's is that they are actually sweet, candy filled nice people with a very nasty shell on the outside. Mind you these impressions were about young NT's, my brothers now are very well mannered balanced and healthy NT's now, and not immature anymore.
I just notice that alot of NT's on the net are still in the immature phase, well I guess alot of people on the net are in that phase, hell I am still growing and trying to mature... man, this was written with literally 48 hours of no sleep, so I really don't know what I just rambled, I need to clean this up in the morning and explain my self, when I wake up.
