How we check facts

Every claim on the channel and this site comes from a source we list, and every episode has a written fact check.

1. Every claim needs a source.Each episode has a source list with a DOI or a link for every paper, article, court record and book it uses. No source, no line.
2. Every fact is checked and marked.A written fact check lists each claim, the source and the words in that source that back it. A claim we could only confirm from an abstract or a second hand account is said with care, or cut. A claim nobody could confirm stays out.
3. Quotes are labelled.A quoted document is retyped in our own style and tagged with where it comes from, for example "Quoted from The New York Times, March 27, 1964".
4. Pictures say what they are.Drawn scenes, maps and reconstructions are labelled on screen. Archive pictures are used only when we know their rights.
5. Tests stay honest.The tests on this site show what you did, then the original study's own numbers with the paper. They never score you, rank you or say what you have.
