Myers-Briggs Personality Test, What is your personality type?

I was very pleased to take the Myers-Briggs personality inventory in class.  My personality type happens to be the rarest of the 16 possible personality types in the human population. I am an INFJ (Introverted, Intuitive, Feeling and Judging) personality type.

While I am not a staunch advocate (haha) of personality tests rendered by astrology (Forer effect, anyone?), I think tests provided by the psychological sciences such as Myers-Briggs, are AMAZINGLY accurate. Once you take the test, go to Wikipedia for your personality type (e.g. type in INFJ or whatever your four letters are) then, you can read about who you are! It’s actually a little scary how accurate the description is.

 I was further impressed by a depiction of my personality type on another random site:

“INFJs can often be found holding down jobs as AM radio talk-show hosts. They can also be found driving taxis in the greater Washington, DC area. Other common jobs often held by INFJs include vagrant, loony, whacko, and writer/director/producer of the television show "Seinfeld." INFJs can also be found feeding that crucial bit of information to determined FBI agents just before they are brutally murdered.”    Okay, just kidding….(I hope)

A great site to read about your personality and how it matches up with someone else’s personality is provided below. Are the two of you compatible? Which personality types pose problems in a relationship? Remember, you can’t alter your personality a great deal, so you’ll have to accept it and find someone else who happens to work for you and/or accepts you for who you are. Also, if you are one of those people who keeps giving everyone else advice on "how they should act" stop, because it won't work. Personality seems to be very ingrained.

Also, what about least common and most common personality types? See site below:

I know there is plenty of information about personality types and relationships but I wonder, what about friendships (and social experience, in general?)? Are some personality types more naturally “loners”? Are some “more accepting of everyone” while others are more gregarious, cliquey and group-thinky? Are there certain personality types who are naturally more popular with people or certain personality types who are naturally smarter?  Also, I noticed that Wikipedia focused heavily on the more positive traits when discussing the various Myers-Briggs personality categories. What about the more negative side? Are some personality types more prone to overconfidence, road-rage or being a clown at the circus?
