Yeah, that test is bullshit. Would be nice if someone would make one that didn't suck. For example, I know my score is going to go up for saying that honesty isn't the best policy in all cases, and strongly disagreeing with there being no excuse for lying, but really, there are. Think about it, Germany 1942, police come knocking at your door, "Do you have any jews here?" "Damn, I was hoping you wouldn't ask that, because honestly I do, and honesty is always the best option, even when it means sending a half dozen innocent people to their deaths."
And then, there are the questions which aren't about what you would do, but about other people, so either you are machiavellian or naive? Isn't that nice.
I heard that the prince was actually intended as a satire of such a prince, haven't heard any corroborating evidence for that, though. Same with the corollary to "It is better to be feared than loved," I heard that he also said that it is critical to not be hated, but as I haven't read the book, I don't know for sure.
