Confirmation bias, epic fantasy, and you. by N.K. Jemisin.
Confirmation bias doesn’t cause the phenomenon of Mysteriously Whitewashed Medieval Europe. (Or Peculiarly Denuded of Women Europe, or Puzzlingly Focused On The Nobility Europe, or any of the other bizarre things we tend to see in medieval Europe-flavored fantasy.) Confirmation bias causes the freakouts that occur whenever somebody points out these phenomena, and names them as inaccuracies.
For a variety of reasons, this is relevant to my interests since post-apocalyptic stories in general and the post-apocalyptic men’s adventures I’m trying to riff on with Defcon are loaded with their own confirmation biases that I want to poke many, many holes in.
