In the online tests I usually score as an INFJ or INTJ and sometimes also as an INFP. I actually classify myself as an INFJ, but the problem is that I don't really think that my Fe function is stronger than Fi. Then again I probably use more Ti than Te... So I'm a bit confused. Something wrong with the theory, eh? Not that I'm an expert on scientific psychology though... I may also have made mistakes in my self-analysis.
Generally I don't like emotions and prefer the company of NT people. Still I'm pretty emotional myself, it's just that I appreciate self control and strength of character (+ intelligence) above all.
I think that my motivations in life are pretty NF-ish. I need to understand the world and people especially; what makes us act and think as we do, and whether it is possible to achieve a truth of any kind. I have an innate need to do something to make people live peacefully and happy and without harming the environment too much. I'm a kind of wannabe political activist, participating in many kinds of organizational workings.
I've been reading these forums for a while and wanted to register just to see if I might find something to comment on. English is not my native tongue so sorry if my language is poor.
