A lot of people score 50% J versus P on there MBTI test and therefore question whether they are INFP or INFJ for instance I think that choosing between INFP and INFJ should be based more on which cognitive functions fits you better FiNeSiTe versus NiFeTiSe, because I'm starting to think that J'ness and P'ness is more complex than just deciding one of them lets take INFJ as an example what the J is saying is that this type preferce to express there main judging function (F) in an extraverted way: Fe. Therefore it seems to me that it is mainly Fe that makes this type appear Jish (and not so there other judging function Ti) what can be then the reason why INFJ's can appear P'sh? - INFJ's are introverts and therefore use Ni as there dominant function. Ni is a perceiving function and the fact that it is there dominant it makes them more P'sh than let say ENFJ's who use there judging function Fe as dominant - secondly I think the development of inferior functions can also have an influence on how J or P you are. When an INFJ has developed there Se function it would them therefore make them seem even more P'sh and therefore I think you shouldn't look at how J'sh or P'sh you are in general to figure out your type but find out in which circumstances you are. For example, I believe I'm INFP but I have always been very J'sh and therefore the MBTI test typed me as INFJ. If I was INFJ it would be my Fe function that causes my J'ness but I have no clue about the workings of Fe. When 'm J'sh it is when someone steps on my values (Fi) or when I'm in organizing mode (Te). And both of them are stress modes for me so in general I'm P'sh and therefore rather INFP than INFJ. Does this make sense? other thoughts?
