This dichotomy is the reason I'm having problems typing myself. I just don't know which of them I value. I went through some descriptions and behaviorally I relate more to "serious" than to "merry" but I'm still unsure because it's as if I value all four judging functions but in different circumstances. (The types I'm considering are IEE, ESE, EII, SEI but I'm open to other suggestions as well)
Fe - I am very capable of being lighthearted and cheering up others/making them laugh and I'm also emotionally expressive. It's pretty easy to influence my values and opinions.
Fi - I have a very strong internal moral compass/I feel whether someone or something is good or bad strongly. I want to have stable relationships and I am sensitive to people's individual feeling needs, i. e. what's acceptable and what offends them. I also probably care more about individuals than groups. I become attached to/infatuated with people very easily.
Te - I mainly use facts when reasoning and arguing. I am quick to judge people on disregarding what is objectively true and I love to correct others (I see how this could be ti).
Tx. (? ) - I love explaining and learning how things work
Ti - I like to understand things before I apply them. I also am interested in stuff such as formal logic and philosophy. I can argue and understand causal reasoning pretty well but I wouldn't call it my strongest area as I'm too scattered to check everything I say for consistency.
My interests also don't really have a practical application and are mostly theoretical (linguistics, history, literature, etc. )
Maybe I don't understand the IMEs correctly?
