Most of the test is by what you say being correlative to what is often or sometimes on your mind. Death being a common element might mean you think about death a lot. More animals than humans has social implications. That sort of way of thinking is why this test is accurate in some ways. In the fully-detailed personality part, it is a bit shaky because the way it does the personality testing is from an analyzed sample of participants’ most common features that correlate to what the image “shows”.
