I probably cannot overemphasize the great numbers of quizzes scattered all over the web that attempts to discover a part of your personality and inform it to you. Unfortunately, I find that most of these quizzes are quite predictable. The choices are predictable, the results are predictable. So while it would be great to answer these personality quizzes for the sake of killing time and self-discovery, I just answer other quizzes instead.
But at one point I encountered a family of personality quizzes that you can hardly determine the question that they try to answer. These quizzes rely on imaginary situations and what your first thoughts about it were. What was that item on the porch? How fast was the water falling from the waterfalls? Those and similar questions are quite common in this family of quizzes.
A little background reading revealed to me that these quizzes are based on Kokology, the Japanese study of the kokoro, or the mind or spirit. These quizzes actually formed a set of books which have then spurned a number of other books not related to the original. The books were designed to ask questions that reveal one's hidden attitudes towards love, sex, family, work, and other elements of life. Sometimes, these hidden attitudes are hidden from the respondents themselves, which may often lead to hilarious self-discoveries. What seemed to be innocent questions were actually a guide to finding out how much sex drive you have, for example.
Well, I assure you that the information that you can gather about yourself through these tests can be downright hilarious. Get prepared to learn something about yourself that you thought was never possible. I don't know if this is backed by any empirical evidence, but who cares? It's fun to take these personality quizzes!
