Evee said we "vibed" similar.
I identify strongly with NPs (in general) and specifically with NTP.
In socionics, type is determined more by one's interpersonal interactions. Some members see me as SFJ. I assume they're basing that assessment on observations of my interpersonal skills. I don't think I'm SFJ but I wanted to run with it and see how others reacted to that typing.
NTP and SFJ are essentially two sides of one coin, so I can see how similarities might be perceived in an individual over the age of 30.
