Myers Briggs Type Indicator (MBTI)

What's with all those personality/pyschometric tests employees are given promptly after recruitment? Apparently employers like to know what "Type" their employees belong to and MBTI is one of the most widely used "tests" used for this purpose. The Indicator is more of an inventory or psychocological instrument rather than a test (or so Personality Pathways says), which suggests right and wrong answers.

I had to do this several times - such is my employment record ;-) and I always got the same four letters at the end of it - INTJ.

A very detailed description of INTJ is available at Typelogic.

Over the years I have noticed the profile is quite accurate (especially regarding fields of employment and relationships) and then among the other stuff given on the Typelogic page , I found a list of INTJs in works of fiction:

Cassius (Julius Caesar)
Mr. Darcy (Pride and Prejudice)
Gandalf the Grey (J. R. R. Tolkein's Middle Earth books)
Hannibal Lecter (Silence of the Lambs)
Professor Moriarty, Sherlock Holmes' nemesis
Ensign Ro (Star Trek--the Next Generation)
Rosencrantz and Guildenstern (Hamlet)
George Smiley, John le Carre's master spy
Clarice Starling (Silence of the Lambs)
