If this quiz is delibrately biased than why do so many people
not score libertarian?
True, it was created by libertarians, but it is in their best intrest to keep it accurate, otherwise people wouldn't spread it. And this is one of their main tools for finiding people with similar views as the traditional left/right model kind of leaves them out. They really don't want a bunch of liberals or republicans thinking they are libertarians and vica-versa.

Tristin Lal: This isn't a tool to get people to "identify with" libertarians, this is a tool to make people aware of libertarians. You can disagree with them completely, what they want is for people to at least be aware of what they stand for.
There is a very good reason why, in addition to the Y/N, there is a "maybe" answer. If you have doubts of any kind of a statement, not an outright dismissal, but doubts, you supposed to answer "maybe". You are not required to have an absolute opinion on anything. If you don't have very strong opions of beliefs about anything, answering maybe on every question, it should accurately place you in the dead center as a Centrist.
And as far as bias goes, yeah there is some subtle bias, but only in the view of "who is best", but not in "what your political philosophy is like", the quiz itself is pretty accurate. Though they do make it seem like "you are only 50% on the road to self-enlightenment on the all-knowing plane of Libertarianism", which isn't very nice.
As far as practicality is concerned, well... If you take any of the extreme of extremes, whether it be conservative, liberal, libertarin, or statist, you end up with crazy stuff that really isn't practical. Charicterizing any political philosophy by it's most extreme and pure form is useful for discussion, but very unfair to use as a reason for dismissal ('these views are too extreme to be practical').
Personally, I don't think that libertarians will ever come to any major of seat of power, simply because their ideas are so radical, and they will royaly tick off those people that don't share those ideas.
I love to argue politics.
