Are you a libertarian? A test you can't fail
If you lean libertarian, you are probably familiar with the World's Smallest Political Quiz, designed for newbies to figure out if they are libertarians, too.
I recently ran across the Libertarian Purity Test, by Bryan Caplan, which seems aimed at promoting a more generous view of libertarianism. The answer key is amusing. I scored in the 60s. The answer key says, "51-90 points: You are a medium-core libertarian, probably self-consciously so. Your friends probably encourage you to quit talking about your views so much."
Caplan, by the way, is the guy who wrote "The Myth of the Rational Voter."
