The best way to figure out your type (or place yourself into something) is simply to understand the system for yourself and then figure out from there. If you are blank, then you can get someone else to type you for you.
I did the questionnaire and ended up with a topic that now has 88 posts in it and is filled with the most incongruous typings imaginable: LSE (!), unspecified Ni-dom (ironic, considering that LSE has Ni PolR), ILI, LII, and LSI. The type that I'm most likely to be, given my life history, has barely even been mentioned as a possibility (that type is IEI).
[ Ni > Ti > Fe > Fi > Ne > Te > Si > Se ][ 4w5 sp/sx ][ RLOAI ][ IEI-Ni ]
Have you looked into any other types if these two don't quite fit?
Well there's no question I'm an INFP in MBTI, which I guess theoretically makes me an INFj in socionics. Maybe there's just something about socionics that I don't like. I think the EII doesn't sound creative enough, sounds more 'harmonious relationships' oriented. Many INFP descriptions are like that too so it's probably irrelevant. I have a vivid mental landscape like the IEI and very much get that out in art as they say Ni does.
This isn't the first I've looked at socionics. It's just never resonated in the past so I tossed it aside. I thought I might as well check it out again. What's the point of socionics anyway?
