Over at Tor.com, I interview Marie Brennan, author of A Natural History of Dragons:
Marie Brennan: I honestly think anthropology is one of the most useful fields a fantasy writer can study, more so even than history. It introduces you to other ways of living, other ways of thinking, and really cracks apart the idea that things which are familiar to you are somehow the natural product of existence, rather than social constructs that, from an outside perspective, may seem very odd indeed. This can be anything from the big ideas (some cultures are horrified by burial of the dead; others are horrified by cremation) to the small details of daily life (which meal of the day is the big one?) to things that are completely random and recent (pink used to be a boy’s color!). Putting those kinds of things on your radar can make your settings far richer and more interesting, whether you’re writing about the past, the present day in a country foreign to you, an invented land based on some part of the real world, or some place as unlike reality as you can manage.
