Interaction Style also.
I believe INFJ will tend to be "Chart-the-course" types, while INFP will be "Behind-the-scenes" Styles.
I finally arrived at typing myself as an INTP after looking through multiple different models of personality.
My Ti was clear in control in terms of precesses. My language was abstract (indicating "N"). I preferred structure to motive (indicates NT-SJ instead of NF-SP), and the temperament preference order was NT-NF-SJ-SP (so that really settled my N-S preference, since in addition, my second highest preference was Ne). Beyond that, I came out "Behind-the-scenes"-"Chart-the Course"-"Get-things-Going"-"In Charge" in terms of Interaction styles. I also considered myself clearly informative rather than directive, and clearly Introverted, so "Behind-the-Scenes" was the appropriate style for me. Combining all that together, I came up with INTP, and I am fairly confident of that.
I wonder if MLC can incorporate all the various veiws of personality into his machine learning algorithm for typing (so that it adapts to find clear preferences in particular views of personality).
