HelloQuizzy.com: The Are You A Sociopath? Test
Egad! You're 26% sociopathic!
Good job! You're within the normal range for the typical human being. As far as sociopathy goes, at least. You might still be clinically depressed, schizophrenic, borderline, obsessive-compulsive or have AIDS. I didn't make tests for those, though.
I should mention now that this test is inherently flawed, due to the fact that someone who was a true sociopath or psychopath would not be telling the truth on an online test.
