OK, so you feel that Ni as defined by socionics is your primary conscious function? ( Introverted intuition - Wikisocion )
And Fe is your auxiliary?
( Extroverted ethics - Wikisocion )
If so, you probably ARE INFp.
Or, do you feel Fi is your primary conscioius function?
( Introverted ethics - Wikisocion )
And Ne is your auxiliary?
( Extroverted intuition - Wikisocion )
If so, you're INFj. Of note, MBTI INFP primary/auxiliary functions are Fi Ne (though defined slightly differently). So if you're INFP in MBTI, more than likely you will be socionics INFj, but not necessarily. However to understand your relationship with ESTPs this difference, like I said, is very important (dual vs conflictor).
