After I saw that autism test, I thought it would be interesting to link this one: A questionnaire to test for psycopathy, narcissism and machiavellianism, collectively known as the dark triad.
I scored a lot higher on this than I hoped and expected I would, higher than average in all respects, and far higher in Machiavellianism.
Based on experience with my own thoughts, though, I'd take the test with a grain of salt. I think, for example, it has a tendency to mistake cynical worldview for manipulativeness. Curious to see how bastardly you duders are.
