As I was briefly lamenting my recent demotion (thankfully away from e621), I came across this interesting survey through Yahoo.
I took it for funsies, to see how dark my personality is.
And according to its results, I am "Infrequently Vile". I mostly put others before myself, though you may find occasions in which your dark side shines.
My Machiavellianism level was around 70%, narcissism at 40%, and psycopathy at 25%.
I'm betting those three numbers are neutral at 50%. If that's the case, then I'm somewhat manipulative. Definitely not here (at least I hope not), but somewhat at home because I don't like inserting others into my "busy" schedule, I tend to be introverted, or something like that.
