I completely understand. I have consistently tested INTJ but suspect I might be INTP for the same reasons...I'm kind of a jack of all trades and I while I have general ambition, I don't have the will to work every day to achieve. I am easily sidetracked. I am, however, comfortable in leadership positions. I've decided to just let it lie, because these things are just supposed to be guides and tools, not a definitive measure of a person.
Since I'm in the same boat, I'll take a stab at Aelan's question. I'd hightail it out of there for two reasons: 1. My friend did it, not me, and I don't want to be drawn and quartered for nothing. 2. While I have a general respect for the law, I wouldn't trust the tribe's system of judgement and punishment without understanding it first and I'd be afraid to receive a death sentence for an accident under a system I don't understand.
