#WritersCoffeeClub Oct 5: Have you ever included real-world disproven science in a work?

Oh certainly. I write a lot of historical fiction, so some of it is what people believed at the time. There's an extended discussion at the beginning of Lament of the Batavii about how the Romans viewed genealogy. Sometimes I write the science as disproven but still believed, but also sometimes I write as though the science is accurate. I have a half-finished story somewhere that's basically what if Lamarck was right, and one of my future pieces involves a man falling through space and time to a world where major conspiracy theories are all true.
