Well, my professional work as a historian is on 20th century U.S public policy, so I don’t use it much.
But when I do ASOIAF stuff, I try to keep it in mind, and remember back to my Art History classes as an undergrad, where they emphasized how the ideals and beliefs of a religion are written into its art – medieval art had figures of different size on the same plane not because they didn’t understand perspective at all but more because larger figures = closer to God – and architecture (how neo-Platonism got woven into the proportions of cathedrals, for ex.).
