Face it! no body cares about your personality, except your fans. Your parents know you better, your friends no cares about your self survey result. Really, they are not needs your selfishness.
Kind of survey like this (on the bottom), just be made for you to feel better. So, when the result came out, I bet no survey (seldom) will tell bad about you. The result is designed for you to share it, an BOM! viral! everybody knows when viral goes up.
FYI! I’m worrying the placebo effect of this kind of survey.
