About the Quiz of Wisdom
The quiz runs on a timer and the questions repeat, so the answers are worth knowing rather than working out. We hold 82 of them. They are not all equally certain, and this site marks which is which rather than presenting a guess in the same voice as a fact — if you are about to tap an answer marked unverified, that is the site telling you it is a coin-flip dressed as an answer.
