Well [MENTION=5684]Elfboy[/MENTION] if you're right that I'm sp/so, then I'm a good example.
I don't know if it's contradictory, per se. I feel like it emphasizes particular tendencies inherent in my type anyway, e.g. always being cautious, always wanting to be prepared, being kind of controlling about scheduling/routine (e.g. meals), and becoming very withdrawn under stress. It also makes me more independent, I think; very happy to socialize, but also wanting to socialize on my own terms, without too much pressure -- if that makes sense.
One thing I will say, though: A while back, someone posted a thread about typing people by their eyes? And one thing I've noticed, that may or may not be BS but seems to work from my personal experience, is that you can totally tell sp and sx from photos. Sp-doms give off this vibe, like they're looking out at the world from behind their eyes, if that makes sense. Like they aren't necessarily present in the world. Whereas Sx-doms always look like they're present; they have very intense stares, with more outward-focused energy. And in this regard, I think I do come across as more introverted, because I think that Sp descriptor applies to me, in videos and photos.
