Introductions aren't really my thing, but it seems like everyone is doing them, so: hi.
I took my first personality test (the very old Myers-Briggs one, not even the original update by Keirsey) around 1993, and have since then taken some variant (usually the classic 70-question model) about once a year.
I am very I and very T. I do well in most social situations (unlike some I's) but really need my alone time to recharge. I am usually capable of tact, but sometimes fail to pick up on it when someone else is getting upset. I'm just more comfortable with logic and known quantities. The justice/mercy dichotomy defined the difference between me and my INFJ ex.
I'm solidly N, higher in the past couple years than I used to be. I flirted with IXTJ for a little while there. My J intensity has varied over the years, and is probably at an all-time high now. Having things planned is comforting.
A cursory glance around suggests that there are a disproportionate number of I's and N's here, which I guess makes sense. Is that right, or am I just seeing things?
