"Do you often think outside the box?" A lot of people who answer "yes" to that question, probably don't, while some who have trouble answering may be pretty far outside all possible boxes. In other words, people choose flattering answers that may not reflect who they really are.
Also the questions may not be quite in the language a person is used to. Neither option may really fit somebody's experience. Sometimes, "Both" or "Neither" or "Sort of" or "Huh?" is the best answer one can give.
A question like "Which do you prefer: Lost or Desperate Housewives is a lot easier to answer. Make a test out of questions like that and you'd have a valuable diagnostic tool.
But golly, it looks like they got me right: "Throughout the entire test, I bet you were searching for "further clarification and hidden meaning" so that you might improve your pitiful life." Wow!
I left that one blank since I don't watch either. Interestingly, the test allowed me to leave it blank. I scored "Almost Perfect!" LOL
