When I’m introduced to someone as a writer, a now familiar pattern of events often follows.
“Oh, really! How interesting!” the someone—let’s call her Jane—says, sounding quite enthusiastic. “What do you write?”
“Science fiction,” I say.
Jane instantly glazes over. “I’m afraid I never read science fiction.”
In other instances, people who know me have read a book of mine out of curiosity and then told me, in some surprise, that they liked it—“even though I don’t normally like science fiction.” Indeed, when a short story collection of mine won a non-genre prize, it was apparently a surprise to the judges themselves: According to the chair of the judging panel, “none of [them] knew they were science-fiction fans beforehand.”
The assumption seems to be that a book that comes with a genre label like “science fiction” must necessarily be lightweight stuff—not really comparable with “non-genre” works.
This may partly be due to the fact that the word “genre” has two different meanings which are often muddled up. The basic meaning of “genre” is simply kind or category or form of fiction, and in that sense, any work of fiction can be assigned to some genre or another. But "genre" is also used in a different way to make a distinction between “genre” and “non-genre” fiction. “Non-genre” fiction is the stuff that is placed on the “general fiction” or “fiction and literature” shelves in Barnes and Noble. “Genre” fiction is the stuff that is placed in its own designated corners: Crime, Fantasy, Romance, Horror, Science Fiction.
