So recently at my school, a group of my friends has discovered something called the Myers-Briggs Personality Test. Apparently the first girl who came upon it did so when her dad mentioned he had taken it a while back while he was enlisted in the military, which I think goes to show that this isn't exactly your kind of, "Which pokemon are you?" personality test.
The test we used is a little more than 70 questions I believe, and can be taken here: http://www.humanmetrics.com/cgi-win/jtypes2.asp
It is usually very accurate, however there have been differences in a letter or two, which I'll talk about later.
Now for a nice bowl of some interesting copy-pasta:
So as you can see, your personality type is based on a combination of four letters, with a possibility of 16 different personality types. Here's a quick overview of them:
When you take the test, you will be given percentages for each of the different areas. If any of them score low (near zero) that could mean you have a well developed alternative of those areas.
Most of my information has been gathered from this website, http://www.personalitypage.com/html/info.html

Also, me and my friends thoroughly enjoy comparing the relationships associated with our personality types, specifically the, "As Lovers" section, http://www.personalitypage.com/html/relationships.html
I predict there will be a large number of INTJs on facepunch, or more specifically the Thinking and Judging aspects.
I personally score as an ESTJ. It's important to point out that it's recently come to light that these tests are a little less accurate than I originally thought, so if you took the time to read up on all the different traits and classified yourself it would probably be more accurate than any test.
