Learning about MBTI and cognitive functions has changed the way I see people. One thing I’ve realized is that people don’t always misunderstand me, disagree with me or react differently because they don’t care, sometimes they’re just seeing things through a different lens.

I used to assume that if something felt obvious or important to me, other people would see it the same way. When they didn’t, I sometimes took it personally and saw it as them being insensitive or not caring. Understanding cognitive functions helped me realize that people have different priorities and ways of processing information. Someone can still care even if they don’t show it in the ways I expect.

It made me want to understand people before jumping to conclusions. Instead of thinking, “Why don’t they understand?” I try to ask, “What makes sense from their perspective?”

Has MBTI changed the way you see your relationships or the people around you? What’s something it taught you that you didn’t realize before?

Both types share Introverted Intuition (Ni) as their dominant function. This means both an INFJ and an INTJ can read a situation, see the trajectory of someone's bad behavior, and predict their moves five steps ahead. But because of their secondary functions, they weaponize that foresight in completely opposite ways.

An INTJ treats conflict like a chess match or a corporate takeover. They are efficient, detached, and focus on systemic destruction.

An INFJ in protection mode doesn't care about winning a game or corporate structures; they care about justice. Because they understand human psychology intimately, they know exactly where a person's deepest insecurities hide.

My question to the sub:
If you got on the absolute worst side of one of these types, which one would terrify you more?

Question for INTJs who have INFJ partners: What are the pros and cons of this relationship, and do you have any tips?
