I've been doing some research on myself. I think it's possible that I'm IxTJ. I've noticed that even though I use quite a bit of Si, I use quite a bit of Ni as well. But I probably use Te the most. Most of the INTJ's profile fits me too. (The ISTJ profile fits about 95%, but the INTJ's fits at least 80%.)
What stuck out the most were my usage of Ni+Te. The whole, "Make theory, turn into working system, explain system to others to use" thing, for one.
I have a few other ideas, but who knows. Any thoughts?

"How dreadful!" cried Lord Henry. "I can stand brute force, but brute reason is quite unbearable. There is something unfair about its use. It is hitting below the intellect." ~ Oscar Wilde - The picture of Dorian Gray
