Not an uncommon fact for Otakus like ourselves are visits to the almost legendary website Quizilla.
This fact stated (and known true), what is left is trying to dig for some answers; most notably "why?" why do people bother taking such quizzes, why is it so thrilling (in general) to find out the results, whichever they may be?
I can answer this from my own viewpoint: for a long time in my life I underwent a very serious crisis, an identity crisis and even more - a purpose crisis.
Not knowing where you should be or even why you should be or do something is a common affliction that, while mostly labeled as a teenager issue, can and will affect anyone, of any age that happens to lose sight of one's bearings.
In reality, that happens much more often than we would like to admit; perhaps our pride won't let us notice how lost we are a lot of the times and we'll keep moving forward instead.
A second point of interest that probably compells people onto answering a series of questions to have some sort of answer is the fact the human life is frail, very easy to destroy; that prospect can be deeply unsettling to many (myself included); it could explain the relative joy of being compared in quiz to say Dante Sparda, Goku or Sanosuke; exceptional in their own ways no matter how fictional they are.
Moreso, a character gotten as a quiz result will be most likely related to us in some way and represent parts of our mind that we may otherwise be unaware of and as a result be incomplete overall.
Personality quizzes are the effect of a human tentatively find as many fragments as oneself as possible - so that one can respond those questions we proposed earlier, and walk with one's eyes open in a definite direction - it being right or wrong is beside the point, only time can say, but that's a subject for another rant, another day.
In closing, I believe quizzes are our attempts to be our own psychologists, behaviorists, an effort towards self balancing and to acheive self wholesomeness; a trivial diversion containing a much more serious meaning therein.
