Personality tests don't measure what they are trying to measure. They are usually wrong. No socionics test or enneagram test has ever given me the right score.. and I have taken every one I have seen.
Some mbti tests give me the right score assuming that I am in fact an intp. Other scores: entj, intj, entp. So, if I want to go by what a test says, I could just take my pick of whats the cooler score. heh
