Shamelessly stolen from elsewhere - take the psychopath test now: http://psychopath.channel4.com/quizzes.html
I scored 42%, and got this feedback:
"Though your conscience is in the right place you also have a pragmatic streak and generally aren’t afraid to do your own dirty work! You’re no shrinking violet - but no daredevil either. You generally have little trouble seeing things from another person’s perspective but, at the same time, are no pushover. ‘Everything in moderation – including moderation’ might sum up your approach to life."
That's a reasonably accurate summary, especially the last bit, being somewhat of a bon vivant!
