Let me start by saying that I don't think that everyone is the exactly the same as their respective descriptions in the MBTI personality profile. As an ENFP, I do see many of my characteristics in my profile, but not all of them.
I have an INTP friend who constantly accuses me of doing or thinking ridiculous things I never even cared about or noticed. When I tell him my thoughts on the matter, he vehemently opposes and insists that I am "bsing my thoughts." He says this because he "read" about "ENFPs substituting their own realities" in this forum. He refuses to believe that I'm actually telling the truth, just because my truth does not incriminate me. He keeps insisting that I'm just trying to be righteous, when I honestly am righteous in his false accusation. He says I have no "concrete proof" on my thoughts. Really, how does someone offer proof when telling their feelings? One of my biggest pet peeves is injustice of any degree. I get furious when someone or I am being wrongly accused. I wish I was one of those people who dismisses an accusation when they know it's wrong, but I am not. I know and admit when I am wrong, and hate injustice against myself. After all, the ability to recognize and accept my faults is one of the reasons why my boyfriend, who is an INTP, and I get along so well without any unnecessary arguments. It is also one of my proudest achievements in refining who I am as a person. Oh, because I am "bsing my thoughts," I am apparently a "typical ENFP."
Generally, are INTPs unable to accept when something deviates from the preconceived truth? Do they substitute their own reality to satisfy themselves, even if it borderlines insanity?
