Of course, there's a fair bit of overlap between types that only differ along one axis -- compare "Logician", INTP, vs. ENTP, "Debater". Or INTP vs. ISTP, "Virtuoso".
The more neutral answers you give, the more overlap across types you'll have. And there were so many questions I wanted to give perfectly neutral answers to, or where my leanings are small and situational.
And yeah, the types are quite broadly written. It's a bit like Zodiac signs, really...
