What is documented
Rice University’s archival catalog contains a record named “Purity Test, 1990s” within student-association material. That is a credible anchor for the checklist’s connection to campus life at Rice.
What is repeated but harder to prove
Online histories often name a precise first year, author, purpose, or freshman ritual without linking to a primary source. Those details may be true, partly true, or repeated from one unsourced site to another. We do not present them as settled fact.
How the test changed online
Once the checklist moved onto the web, publishers created many versions. Wording was modernized, questions were reordered, and new topics were added. Search engines now surface a mix of legacy checklists, personality-test products, fan-made adaptations, and thin copies.
Why our version exists
Most competitors focus on owning the checklist. We focus on the experience around it: private answer storage, a cleaner one-question flow, a playful result people actually want to share, and honest boundaries around history and meaning.
We will update this page when better primary evidence becomes available.
