The Record Corrected
Across the Wasteland, 225 layers do one job: each takes something widely believed and hands you the check that settles it. The pattern underneath them is the reason this is hard — a false belief is not killed by a better argument, only by a check you can run yourself: an earlier date, the actual primary source, the arithmetic recomputed, the thing measured. Psychologists even named why the beliefs hold on — the illusory-truth effect, where a claim repeated often enough begins to feel true. Repetition is not a check. Every layer here is one of those checks, made operable: drag the anachronism onto a timeline, touch two things at the same temperature, watch the famous chart draw itself from pure noise. Every quotation is verbatim from a cited source; every number is recomputed in a committed verifier; every uncertainty is named.
Playable ways in
Repeated Until True
A false claim survives not because it is true but because it is repeated: repetition alone makes a statement feel truer, even to people who can state the correct f…

The Level and the Rate
Four facts the internet answers badly — metal feels colder than wood, the Moon never falls, the Sun raises a smaller tide than the Moon though it pulls 179× harder…
Combine portals — one engine, several of the corrections below under it. Or walk the record movement by movement, sorted not by subject but by the kind of check that ends the argument:
I. The quote that was never said
Lines everybody can finish — that the record cannot. Marie Antoinette never said it; Holmes never said it; two famous proverbs survive saying the opposite of the original. The cure is always the same: open the earliest source and read what is actually there.
- Language
The Quote That Arrived Before She Did
Marie Antoinette never said 'let them eat cake.' The line is real — it's in Rousseau's Confessions, written about an unnamed princess while she was a child of nine…

The Phrase Holmes Never Said
Everyone knows Sherlock Holmes says 'Elementary, my dear Watson.' He doesn't — not once in any of the sixty stories Arthur Conan Doyle wrote.

Almost everyone uses it backwards — as if an awkward counterexample could confirm a generalisation.
- Language
The Rest of the Proverb
"The real, full, original version is actually…" — and the twist reverses the meaning you grew up with.
II. The word younger than its story
Every folk etymology is a guess about a date, and a date can be checked. “Boredom” is younger than the feeling it names; the tidy acronym is almost always a backronym; the canals of Mars were a mistranslation of channels. Put the origin story on a timeline and watch it fall behind the word.
- Language
The Word Was Younger Than the Feeling
Type 'is boredom modern?' into a search box and you're often told Dickens coined the word in Bleak House.

III. The history with a date
The myth and its correction both happened — and the correction is older. Nobody learned in 1492 that the Earth is round (Eratosthenes measured it ~240 BCE); the Great Wall was never visible from space; the commons Hardin doomed were the unmanaged kind Ostrom later saved. Each fix is itself a documented event.

IV. The sensation mistaken for a property
What you feel is a fact about the sensing, read as a fact about the world. Metal is not colder than wood (it pulls heat faster); the horizon Moon is not bigger; the mirror does not swap left for right (it reverses depth). Measure the thing itself and the property the feeling reported is not there.

V. The mechanism told backwards
The everyday explanation names a real effect — pointed the wrong way. Glass does not flow; a bike’s spinning wheels do not hold it up by gyroscope; pressure does not melt the skater’s ice; the resting roast keeps cooking by conduction, not by “juices redistributing.” Run the actual physics and the folk cause inverts or disappears.
