Just adding another INFP to the thread. NT's may be interested in intellectual debate hence the number of NT's in this thread, but NF's are typically the "people-person" typeand naturally I'm one of those who love getting to know about people. Actually persuaded a lot of my friends to take the test, and started cataloging the results to assess the accuracy myself. I believe the test reveals the nature aspect of the human mind, but a person's background (nurture asepct) colors the personality type.

But, I'm happy there are others who are into this. What books do you guys have on MBTI? Some of my books:-

1. Please Understand Me
2. Please Understand Me II
3. Type Watching at Work
