INTJ
I actually went thru some trouble to check out the INTJ open mailing list..
http://epistolary.org/mailman/listinfo.cgi/intj-open
I would say its more of a lot of INTJs trying to proof(perhaps a little too hard) that they are INTJ rather than it really shows any characteristics of INTJ between the lines...
But how well researched and surveyed are these tests (i am being INTJ here and I am one, or so they say). Are they done be professionals, are they peer-reviewed, etc.
Cuz I have always been skeptical about such "tests" since the websites look very crappy and unconvincing but always had a lot of fun taking them..
