Where the Rice Purity Test came from

The Rice Purity Test is a 100-item checklist of life experiences that spread from Rice University in Houston, Texas, scored by subtracting one point for every item you have done. That much is agreed on by everyone who has written about it. Almost every other detail you will read online — the founding year, the original purpose, the name of whoever wrote the questions — is repeated without a source, and this article separates the part of the record that holds up from the part that does not.

What the record actually supports

Three things are safe to say.

The test is genuinely associated with Rice University. The name is not marketing invention by a quiz site; students at Rice have circulated and discussed the questionnaire for decades, and The Rice Thresher, the university's student newspaper since 1916, has covered it as a campus fixture rather than as an outside curiosity.

It travelled through orientation culture. The version most people describe is a paper sheet passed around in the first weeks of the academic year, when a new cohort is looking for fast, low-stakes ways to work out who everyone is. Rice's orientation week is the setting named in most first-hand accounts.

It has no author. No individual has ever credibly claimed the canonical 100 questions, and no edition carries a byline. A document with no owner cannot be revised by its owner, which turns out to explain a great deal about the test's later behaviour.

The 1924 date, and the two documents that do exist

Correction, 5 September 2026. This section previously said that the most-cited write-ups describe the test "without producing an original document". That was wrong. Wikipedia's purity test entry cites two dated items in Rice University's own archive, and they are named below. The conclusion does not change — the 100-item list is still not attested in 1924 — but the record is better than this article gave it credit for.

Search for the test's origin and you will be told it began in 1924, or 1935, or "the 1920s". Two of those dates have paper behind them, and neither piece of paper is the test people take today.

The Thresher of Friday 7 March 1924 — volume 9, number 22, page 1, under the headline "Rice Girls Not Quite Half Bad" — reported an informal ten-question survey of 119 female undergraduates, asking about drinking, dancing and what they did or did not tell their mothers. Ten questions, one page, women only. The issue is in Rice University's digital collections.

The paper came back to the idea sixty-four years later. Its April Fools' edition of Friday 1 April 1988 — volume 75, number 24.5, page 8, printed under the joke masthead The Rice Trasher — carried "The New and Improved 1988 Rice Trasher Purity Test", built from a list of 150 questions. That issue is in the same archive.

Both issues are held by the Woodson Research Center at Fondren Library — what the university did and did not do with this test is set out on the Rice University page — and I confirmed each one exists there with the volume, number and date given above. The scans are page images rather than searchable text, so the headlines and contents come from Wikipedia's citation of those items rather than from my own reading of the page — worth knowing before anyone repeats them as read.

There is one more dated record, and it is the earliest that names a hundred-question Rice version at all. On 19 October 1993 a message forwarded around MIT catalogued 33 purity tests then circulating between campuses; one line of it reads purity-100-rice — Rice University Version. The file itself is gone — the URL 404s and the Internet Archive holds no copy — so nobody can say which hundred questions it held, but the entry is a third party writing the words "Rice" and "100" together five years after the Thresher's parody issue. The whole family of versions is here.

What none of it supports is the sentence quiz sites keep passing to each other: that the 100-item list you can take today was administered at Rice in 1924. The 1924 document is a ten-question survey of a hundred and nineteen women. The 1988 one starts from a hundred and fifty questions and is a parody issue. Purity questionnaires as a genre are genuinely old and well attested on American campuses — long yes/no lists about drinking, dating and rule-breaking ran in college humour magazines and fraternity life through the first half of the twentieth century — but "the tradition is a century old" and "this list is a century old" are different sentences, and only the first one has documents.

Here is the honest scorecard:

The genre had many lengths before 100 won

The Rice version was never the only purity test. Through the 1980s and 1990s, versions with 400 and 500 items circulated on bulletin boards, Usenet groups and early personal web pages, along with themed spin-offs aimed at particular subcultures. Those longer editions asked far more granular questions and were, as a result, tedious to finish and awkward to score.

The 100-item format won for a boring reason: the arithmetic is invisible. Every question is worth exactly one point, so your score is one hundred minus the number of boxes you checked, and the result is already a percentage. A 400-question test requires division. A 100-question test requires counting, and a machine can do it in front of you. When the format moved to the browser, that property made the 100-item edition the one worth copying.

Paper to browser, roughly 1995 to 2005

The move online was not a redesign. Someone typed the sheet into an HTML form with 100 checkboxes and a script that subtracted; the next person copied that page's source; the next mirrored the copy. Dozens of near-identical implementations exist because the question text propagated as source code, not as an edited document.

That copying pattern is also why you can date a given copy from the inside. The editions that propagated as raw HTML in the 1990s and 2000s ask about nothing you would do on a phone. The list here has exactly three such items — explicit messages, photographs and video chat, at questions 32 to 34 — and copies that predate the smartphone carry none of them. That absence is not evidence of a 1924 origin, but it does put the wording of those copies before the smartphone, which is a firmer date than any of the years people quote at you.

Our edition is one of the copies that carries them, and it is worth saying so plainly. The classic list here has all three phone items — an explicit message at 32, explicit photographs at 33 and explicit video at 34 — because the four live copies it was reconciled from all carry them. The consequence is that a score from this site is not strictly interchangeable with a score from a frozen 1990s mirror — the same person can check items here that the older sheet never offered them. That is the trade: an unrevised list is a better historical artefact, and a revised one is a better description of a life lived after 2010.

The 2020s revival

The test returned at scale on TikTok from about 2020, and the format of the revival mattered more than the test. Scores became a short video: a number on screen, a reaction, a caption inviting comparison. Group versions followed — friends filming their scores together, couples comparing, whole classes posting.

The revival changed the audience. The original setting was a college orientation, which meant respondents were mostly eighteen or nineteen. A short-video platform delivers an audience skewing much younger, and because the test is cumulative — you can never score higher than you did last year — a younger audience mechanically reports higher numbers. If you want to see what the current mix of respondents looks like rather than guess at it, our live statistics page shows the distribution as it stands today, and it is worth reading with that selection effect in mind rather than as a portrait of the general public.

What it is, stated plainly

The Rice Purity Test is not a psychological instrument. It was never validated against anything, has no norming sample, no reliability testing, and no scoring theory beyond subtraction. Each item counts one point, so shoplifting a chocolate bar and being arrested weigh the same, and the total silently assumes that all hundred experiences are equivalent units — which no researcher designing an instrument would accept.

What it does well is start conversations, because it is specific. "Have you ever been arrested?" produces a story; "how adventurous are you, on a scale of one to five?" produces nothing. A hundred concrete questions is an efficient way for strangers to find out who they are sitting next to, which is exactly what an orientation week needs, and it explains the test's survival better than any origin myth.

Where to go next

If you want the number itself, take the 100-question test. If you already have a score and want to know what it implies about which sections you checked, every value from 0 to 100 has its own page under score meanings. For how the different versions relate — and why a score from one is not comparable with a score from another — read purity test versus innocence test, and for what the comparison figures on this site do and do not claim, read how to read your percentile.
