And yet a lot of mbti INFJs, when they test socionics, seem to come out INFj (EII) not INFp (IEI)
At the same time, I've been badgered by plenty of INTxs that the two systems are one and the same and should be merged and that I cannot be INFp, for that very reason
I agree with you on all of this; I also am puzzled by those who say they are one and the same. I find it strange, considering socionics function lineup is in fact not the same as mbti function lineup (i.e. ISFp in socionics, which if systems are one and the same would automatically equal ISFJ in mbti, has SiFeNiTe for ISFp, and SiFeTiNe for mbti.
When I read the descriptions of all of the socionics types, consequently, to me they all seem like a blend of two mbti types. So ISFp seems half ISFJ and half ISFP, and ISFj seems half one and the other as well. So, honestly [MENTION=5494]Amargith[/MENTION], I can understand why you think you relate to more than one socionics type. For the same reason, I can't identify with any single socionics type, though, ISFp prob makes most sense for me. But, I'm not mbti ISFJ.
And if, as is quite possible, 'function order' means something different in mbti vs socionics, it still remains that the socionics descriptions are not synonymous with mbti descriptions - i.e. mbti ISFP and socionics ISFj personality descriptions have some pretty distinct differences.
So I think that's why there are some mbti INFJ's who identify more with socionics INFp, and others with INFj. Different categorizations on personality.
