You are 71% Rational, 14% Extroverted, 57% Brutal, and 71% Arrogant.
You are the Sociopath! As a result of your cold, calculating rationality, your introversion (and ability to keep quiet), your brutality, and your arrogance, you would make a very cunning serial killer. You care very little for the feelings of others, possibly because you are not a very emotional person. You are also very calculating and intelligent, making you a perfect criminal mastermind. Also, you are a very arrogant person, tending to see yourself as better than others, providing you a strong ability to perceive others as weak little animals, thus making it easier to kill them. In short, your personality defect is the fact that you could easily be a sociopath, because you are calculating, unemotional, brutal, and arrogant. Please don't kill me for writing mean things about you!
To put it less negatively:
1. You are more RATIONAL than intuitive.
2. You are more INTROVERTED than extroverted.
3. You are more BRUTAL than gentle.
4. You are more ARROGANT than humble.
Your exact opposite is the Hippie.
Other personalities you would probably get along with are the Spiteful Loner, the Smartass, and the Capitalist Pig.
