I got a five and honestly, I think the thing kind of sucked.
It suffered terribly from Hedberg syndrome, the aforementioned two part dependent questions along the lines of "do you like sugar...or pcp?" The quiz basically penalizes you for being an honest person. Then again, it's hard to take a quiz seriously when the "borderline" area accounts for around 50% of the scoring window.
In the interest of this not being just another bullshit list thread, I'll say that I find the entire thing suspect at best. I can attest that at least one person I've seen get a zero is, by my definition, a certifiable ass. I'm getting the impression that others are either failing to be honest with themselves (Seriously, how anyone short of maybe Tania could get a zero on this with some of the snark that shows up on this forum is proof of that on its own) or are only applying these questions to certain aspects of their life, rather than a whole as some of the higher scorers probably did (I kind of had to, being unemployed right now and all).
