What is a Purity Test?
Ranging anywhere from 10 questions to 1500, a "Purity Test" measures your percentage of purity/corruption in a certain field. Some tests are serious, some esoteric, some are just bizarre, but there's no denying their popularity. Sites like the Armory host and have links to literally hundreds of different tests on every possible subject imaginable, everything from sex to computers to Gilligan's Island. They're closely related to the ever-popular personality tests, as they give numerical, tangible results about the most fascinating topic imaginable: the human race.
What's in a Purity Test?
Most Purity Tests have possible scores anywhere from 1 to 99%, but most scores in well-designed tests are designed to fall between 40-60% pure/corrupt (standard distribution curve). Purity Tests ask numerous (sometimes embarassing) questions of their users, and as they say, all technicalities count.
Purity Test Culture
Extremely popular among people aged 13-40, Purity Tests are the subject of much discussion and quite a few parties. It's common to post Purity Test scores, discuss them with friends, and even plan to 'improve' them, using the Purity Test itself as a 'checklist' of things to do/try. They're easily obtained using any search engine (if you can find this article, you can find a purity test).
What's the Big Picture?
More than just a passing fad, Purity Tests are a great way to get anonymous information about the denizens of the internet. One Purity-type test is actually an AI experiment attempting to identify sex by the answers given to questions.
