The concept of lie-to-children was discussed at-length in 2000 by Andrew Sawyer, where the subject itself was included in the article title: "Narrativium and Lies-to-Children: 'Palatable Instruction in 'The Science of Discworld. Sawyer wrote that: "The 'lies-to-children' we tell ourselves about science are a different form of science fiction: one, perhaps where 'fiction' qualifies the word 'science'. They are 'fictions about science' rather than 'science fictions'." Sawyer concluded: "The strength of "The Science of Discworld"—and why in many ways it is something new in science writing—derives from Pratchett's story being more than a parable constructed for the specific purpose of explaining what the scientists have to say. It is, as has been said, a commentary/parody of the scientific method".
