Robot
You are 85% Rational, 0% Extroverted, 14% Brutal, and 0% Arrogant.

You are the Robot! You are characterized by your rationality. In fact, this is really ALL you are characterized by. Like a cold, heartless machine, you are so logical and unemotional that you scarcely seem human. For instance, you are very humble and don't bother thinking of your own interests, you are very gentle and lack emotion, and you are also very introverted and introspective. You may have noticed that these traits are just as applicable to your laptop as they are to a human being. In short, your personality defect is that you don't really HAVE a personality. You are one of those annoying, super-logical people that never gets upset or flustered. Unless, of course, you short circuit. Or if someone throws a pie at you. Pies sure are delicious.
