NT's are seen as cold hearted and cynical. To which I say
. Remember when you pretended to be hurt as a kid to get attention? They're the ones who never grow out of it. Seriously though, I don't know many NT's (2), but one of them is very caring and considerate (to people he thinks are intelligent anyway), the other is all cute trying to pretend he doesn't have emotions, which leads to him not realising when his feelings are showing. During these moments everyone knows exactly how he's going to act, even though he doesn't.
... I've seen loud and violent ISFP's, and non-judgemental, uncontrolling ENTJ's.
