Hey guys, just wanted to catch your opinion. Ni as I understand it is a conclusive function. It takes multiple external stimuli and tries to form insightful, unifying concepts that link them together. An INFJ for example is known to observe a person's clothing, facial expressions, tone of voice etc. and make very penetrating insights about their personality and personal history. I really hope I got all this right, because my question depends on it.
I've noticed that my INTJ can be really stubborn and repetitive because of his Ni. He's an extraordinary man in my eyes; very smart and very logical. However he can sound like a broken record at times. For example, he's not a type 6 but he sees conspiracies everywhere. When something big happens and the reasons aren't logical he automatically thinks that there's some sort of under the table thing going on, when of course, that doesn't have to be the case. It's like he's too eager to form that same conclusion over and over again.
I think every function has a dark side and the dark side of Ni may just be stubbornness. No matter what the reason is, if your conclusion is not the best explanation, yet you are convinced that it is, you are being stubborn. What do you guys think? Am I making any sense to you?
