First of all, this entire post was translated by AI because my English is not very good. The ideas and experiences are mine, but the wording was translated for me.
I’ve been interested in MBTI and cognitive functions for years, and recently I’ve started questioning whether the standard INFP vs INTP distinction fully describes my experience.
I know that according to classic MBTI theory, your core type does not change. An INFP leads with Fi and an INTP leads with Ti. However, what confuses me is that both functions seem unusually strong and natural for me, not just as occasional tools.
Some background:
As a child, I was highly emotional, sensitive, idealistic, and deeply aware of my personal values.
At the same time, I was extremely curious, analytical, and obsessed with understanding how things worked.
I learned quickly, enjoyed studying subjects deeply, and constantly questioned things.
As I grew older, I started running a business and later became interested in stock trading. These experiences forced me to develop stronger logical and objective decision-making skills.
Today I notice both sides operating regularly.
Ti-like traits:
Obsessively researching topics until I understand them thoroughly.
Wanting internally consistent explanations.
Feeling uncomfortable when information contradicts my existing framework until I resolve the inconsistency.
Enjoying analysis for its own sake.
Often studying a subject until I reach what feels like the core mechanism behind it.
Fi-like traits:
Strong awareness of my emotions and internal values.
Frequently evaluating whether something feels personally right or authentic.
Being emotionally affected by criticism even when I know logically it shouldn’t matter.
Having a rich inner world and vivid imagination.
Spending a lot of time reflecting on who I am and why I think the way I do.
What makes this confusing is that neither function feels secondary or occasional. Both Ti and Fi feel natural, familiar, and present throughout my life.
Another thing that makes me question the standard model is my relationship with the so-called shadow functions.
After years of running a business, I developed what seems to be very strong Te. I use it constantly when making decisions, setting prices, evaluating market behavior, comparing outcomes, and testing whether ideas work in reality. At this point it feels far too developed and natural to be something that only appears occasionally as a shadow function.
At the same time, I barely relate to Ni. After studying Ni in depth and looking for examples in my own life, I can occasionally identify moments that resemble it, but it appears very rarely compared to Ti, Fi, Ne, and even Te.
Fe is another interesting case. While I understand other people’s emotions and motivations reasonably well, my Fe seems much less developed than my Te. Social adaptation and group-oriented emotional awareness have improved over time, but nowhere near the level that my Te has.
Because of all this, I find myself wondering:
Am I simply an INFP with unusually developed Ti and Te?
Am I an INTP with unusually strong Fi?
Or does MBTI’s categorical model sometimes struggle to describe people who sit extremely close to the boundary between two types?
I’m not claiming MBTI is wrong, and I’m definitely not claiming to have discovered a new personality type.
I’m simply curious whether anyone else has experienced feeling like both Ti and Fi are core parts of their cognition rather than one clearly dominating the other.
Has anyone else experienced something similar to an “INxP” pattern, where the distinction between INFP and INTP becomes unusually difficult to identify?
