Myers-Briggs is incredibly useful for people who fall into INFJ because the categorization is relatively rare and can help them place a few of their more socially maladaptive tendencies in context.

Admittedly, the test is arbitrary in many ways, but you can't deny the questions -- about introversion, how logical, emotive, and judgmental you are, etc -- represent the subjective experience we have of others' personalities, even if the categories are incomplete, nonlinear, redundant, or transient.

yes, I always score very very strongly in INTJ. It may not be as useful as a full psychological evaluation for describing my personality, but unlike Tarot/astrology, if you know what INTJ means, you can understand how I function and how I see myself. (not very social/emotional, very logical, stubborn, aptitude for systems-building)
