When I went to new manager school at my job they gave us that test. I'm an INTP. That description fits me perfectly. The test we took was administered by a professional group, and we had sliding scales for each of the types, I'm HIGHLY introverted. I generally don't care for personal interaction. I avoid it when possible. Doesn't mean I don't like people, just don't like interaction. I love theories. I study calculus and physics because it fascinates me. I'm highly intuitive. I can "connect the dots" from information given quicker than most. I'm a weirdo I guess.
