I'm an INTJ type:
44% introverted,
75% intuitive,
12% thinking,
1% judging.
I am
* moderately expressed introvert
* distinctively expressed intuitive personality
* slightly expressed thinking personality
* slightly expressed judging personality
Keirsey.com notes that I'm a "mastermind", which is surely flattering.

EDIT: wow, this is pretty accurate. The emphasized part is
exactly how I prefer to work with others.
"Masterminds are rare, comprising no more than, say, one percent of the population, and they are rarely encountered outside their office, factory, school, or laboratory. Although they are highly capable leaders,
Masterminds are not at all eager to take command, preferring to stay in the background until others demonstrate their inability to lead."
EDIT 2: though I must admit I'm kind of disturbed by the fact Ayn Rand is listed as having the same personality type as me.
