I did a test recently on this, so I won't do this simpler one again.
But sadly my type (INFJ) is not in the poll

The "I" and "J" are almost disregardably weak in my case - both are, from what I understand, developed recently rather than inherent to me. I was probably more of an ENFP to start with, but a relatively isolated lifestyle I've had over the past few years (largely by necessity of living in a mostly foreign culture, no family or friends around, focus on my grad studies, research, teaching) has made me develop introverted coping strategies and a necessity for being a bit wary of people (i.e. for passing quick character judgments). In general though, intuition is my dominant trait (75% last I checked).
