Yes. No charge, no account, no email address. Everything on this site is available immediately and in full.

No. The quiz is built as a small JavaScript file that runs inside your own browser. Your ticks never leave your device and are not sent to us. Closing the tab discards them.

You start at 100. Every box you tick removes one point. Tick 28 boxes and you finish on 72. That is the whole formula.

No. The score counts experiences, nothing more. Most of the gap between two people comes down to age and circumstance rather than character, and the list itself is a hundred arbitrary items rather than a considered measure of anything.

Nobody knows, and any exact figure you see quoted is guesswork. The people who take internet quizzes are not a representative sample, question lists differ between sites, and no answers are verified.

We wrote our own. Reproducing another site's wording creates copyright problems, and many circulating versions include explicit material we would not put in front of a general audience. Our list produces the same 0 to 100 range using experiences suitable for all readers.

This site is intended for readers aged 13 and over, and we do not knowingly collect information from anyone under 13. Our questions are written to be suitable for a general audience.

As often as you like. Use "Start over" to clear every box. Many people retake it once a year to see what has changed.

No. This is an independent site with no affiliation to, endorsement from, or connection with Rice University or any other institution. The name describes a widely known quiz format.
