oh i know, i studied this recently actually. I took an interesting and apparently scientifically attested one online for my psychology course, but it is more thought provoking rather then accurate. It even comes with a disclaimer, and says that if someone you know well such as your family or partner or close friend thinks that it doesnt describe you accurately, its wrong. However, some of the questions were really unspecific and made me think real deep about the meaning and what I in fact feel or think. It was interesting, to say the least.
