It's been a little while since I've taken the Myers-Briggs personality test. I talked to one of my law professors about it, which prompted me to go back and look at it again. Historically, I've found myself to be an ESTJ.

However, I think I've moved over to slightly more "I" (as opposed to "E") and "N" (as opposed to "S".) That means I remain solidly in the "T" and "J" camps, but depending on how I feel at the moment, I can end up an ENTJ, an ISTJ, or even an INTJ! (Supposedly, C.S. Lewis and Jane Austen were both INTJs... I would not be ashamed to be among that company.)

Obtaining entirely accurate results in so-called personality tests is difficult in large part probably because we can't avoid the fact that, when we choose answers, they are a reflection of our own self-perception, and not how others perceive us. However, I think this inaccuracy can be mitigated when the test, such as Myers Briggs, attempts to measure our preferences rather than our abilities. That is, not that you act perfectly like the personality type, but that this tends to be your more natural disposition or the functions that you prefer to use most often. "E" types enjoy many social interactions, but this doesn't mean they can't sit down and spend quality alone time... it just takes more effort for them than the "I" types. Also, "S" types are also capable of abstract thought, but it is not as natural as the "N" types. And so on, and so forth.

Looking over the descriptions of the different types, I'm guessing I'm a good mix of ESTJ and ENTJ.
