What does Less Wrong know about the Myers-Briggs personality type indicator? My sense is that it's a useful model for some things, but I'm most interested in how useful it is for relationships. This site suggests that each personality type pair has a specific type of relationship, while this site only comments on what the ideal pair is for any given type. But the two sites disagree about what the ideal pairings are.
Personality Page is not mainstream Jungian; they seem to be of the opinion that sharing a dominant trait of opposite attitude is most beneficial. More mainstream MBTI sites will tend to agree with Socionics that completely opposite traits are the most complementary (for example Fe and Ti) but disagree on what of these traits correlate to a J or P.
So if you go by the theory that J/P correlates to extroverted conscious traits (the MBTI position), INTP and ESFJ are complementary. If you go by the theory that J/P correlates to the dominant trait, INTJ is ESFJ'...
