Every time I take a test, I come out as a slightly different personality type. Back in 2003 I was an ISTJ, then swung to ISTP a year or so later. It turns out the tests typically have a very low test-retest repeatability, which makes me even more suspicious of the system...
I've now gone ultra fluffy, and have tested as INFP.

Wow - so not like me. I must be having a lame pathetic day. However, it seems slighty more like my work style - I was given a Myers Briggs derived test at work recently, and came out triple-high showoff and handwaver, which was entertaining - in fact, good at everything except acting on stuff. Perhaps the triple high accounts for everything except the introvert, explaining the changeable results for the three tests.
On the other hand, it could just be a faulty, crude tool for understanding a person?
