Well if you construct a questionnaire and whatever the score there is a slightly flattering description then everyone who does it will feel pleased with themselves won't they. This is trivialisation of psychiatry, yet again in the attempt to lure in viewers.
The questions are quite transparent and if you tick all the obvious choices, including snake (and get 10%) this is what it says about you:
You can play hardball with the best of them! You know what you want and are not afraid to go for it – even if it means bending the rules occasionally and putting a few noses out of joint on the way. Nothing fazes you. You are decisive, self-confident and pretty much up for anything. You are a ‘means-to-an-end’ person. For you, it’s not necessarily a matter of right or wrong, but of what gets the job done. ‘Bring it on’ is your mantra, but to help those around you keep their heads, you should learn some tricks to help you temper your self-satisfying tendencies...
But you wouldn't want to upset a psychopath when they could easily find out where you work, would you? 
A more appropriate summing up might be "You are a nasty bastard aren't you. Been locked up yet?"
