I'm curious, as I've never taken the MBTI before- has anybody taken the real deal? What are the questions like? Are they along the lines of "do you prefer to take the initiative in group situations," or are they like "the word 'rabbit' describes you better than the word 'purple?'"

Because with more concrete questions, it seems like your results would be way off the mark. The person least qualified to evaluate your personality is you- because while you might recognize the value of certain character traits- say, organization- and then subconsciously apply those traits to yourself because you identify them as positive, an outside observer might be more likely to rate you from empirical evidence. No, you're not organized; no, you don't easily grasp complex theoretical frameworks; no, you're not the life of the party.

Basically: with obvious questions, your answers might be colored by what you value rather than by how you actually react in a situation. And while your values certainly account for a portion of your personality, they're not the whole of it. In fact, they're the most mutable part, if you sufficiently widen the time frame.

I'd like to take a test with some seriously oblique shit going on. "You're in a forest and you meet a tree frog. Do you: A) have a drink of water, B) call your best friend, C) sing to the frog, or D) chart the stars?" No idea how somebody would map the psychosocial framework behind something like that, but it seems like if the test taker can't divine the purpose of the questions, you'd get much more honest answers, and a much better test.
