Only 50 questions, this purity test will ascertain, very quickly, your purity on three different measures:
sexual purity,
substance abuse purity, and
moral purity.
Other purity tests exist, but this one usefully separates the 3 typical "impurities". Because it's short, it's best for people in the middle 99th percentile. Sex workers and babies: this is not for you.
And for those hoping to prove themselves insane: I will not focus on extremes (eating or sculpting shit, doing animals) because those questions just drag the test out for most people. If it's really important to you, write a poem or manifesto.
