I had heard a bit about this in discussions of inaccurate information from AI engines like ChatGPT. But hearing it directly from TPM Readers AT (a research librarian) and JC brought it into sharper relief for me. Inaccurate information can mean a lot of things. You can say Thomas Jefferson died in 1846 when in fact he died in 1826. Other inaccuracies are more complex and pernicious.
