That test is biased towards conservatives, and this coming from a conservative. I was thinking that the entire time while I was taking it based off how they worded the questions. Furthermore, 52 questions, or however many it was, is not enough to really determine anything by quotient. As far as radicalism is concerned, I don't think that has any bearing on liberal or conservative ideals, it was how you answered your questions. If you chose "Strongly disagree" or "strongly agree" for most of your answers, then it would probably categorize you as a "radical" which is another objection that I had with the test.
It was fun but it had many inconsistencies to make it credible.
