While taking a class on fantasy literature in graduate school, I had the idea to go to a local elementary school where a friend worked and count the books in the library to see how many fantasy titles there were. It turns out there were plenty of fantasy books, but my attention was caught by a different genre’s absence: there were barely any science fiction books. I wondered why, and I ended up pursuing the answer for years. I looked at school libraries in almost every region of the U.S., surveyed teachers and librarians, recorded readings with children, and of course read lots and lots of books. Science fiction for children, I discovered, is full of contradictions.

When I looked at very different libraries all across the country, I saw the same low supply of science fiction that I had observed in that first elementary school library, but I also saw a high demand for it. In each library, only about 3% of the books were science fiction. I expected to see a corresponding low number of checkouts. Instead, the records showed that science fiction books were getting checked out more often per book than other genres. While realistic fiction books were checked out, on average, one to three times per book and fantasy books were checked out three to four times per book, science fiction books’ checkout numbers were as high as six times per book. These libraries may not have many science fiction books available, but the children seem to compensate by collectively checking out the available books more often.

The librarians were just as surprised as I was. Library software doesn’t keep track of each book’s genre, and so librarians have no easy way of knowing that science fiction books are being checked out so often. Librarians are, however, aware that there isn’t much science fiction available. There just aren’t as many choices as there are for other genres.

My research has led me to believe that this shortage of science fiction exists simply because adults assume that children don’t want it. There are several larger cultural reasons for why adults find it easy to assume that kids won’t like science fiction. In short, adults often associate children with nature and innocence rather than science and experience, and this bleeds into what adults think children like.

Author Jon Scieszka once told me that his editor asked him to reduce the science in his science fiction Frank Einstein series because it would be off-putting for kids (Scieszka refused). An indie publisher informed me that it doesn’t acquire many science fiction books—even good submissions—because it expects low sales simply due to the combination of genre and target audience. If no adults think that children like science fiction, then no one makes it, no one sells it, and no one buys it because adults are in charge of these processes.

The cycle perpetuates itself, but is hard to see because of the way that science fiction is—or isn’t—talked about. In my survey, librarians and teachers said that they recommend science fiction to individual readers but rarely use it in group storytimes or lessons. They feel that the genre is too hard and polarizing; it’s either very popular or very unpopular among children. Several even avoid the term “science fiction” when recommending the books, for fear that it might deter a potential reader!

Even though, based on my data, children seem to like science fiction, that doesn’t mean they are immune to the stereotypes that adults indirectly teach them about it. Because of the way it is avoided, children may not know that they like science fiction. Indeed, many of the most frequently checked-out science fiction books in school libraries—such as Margaret Peterson Haddix’s Shadow Children series and the Lego Star Wars novels—are often marketed primarily as something else, like adventure or humor.

Supply issues are nothing new these days, but this one, at least, can be easily fixed. In fact, there used to be a similar issue with nonfiction, but it has improved significantly in the last two decades. Not long ago, many adults (including professional educators) assumed that children preferred fiction to nonfiction. Around the turn of the 21st century, researchers began investigating the books taught and available in classrooms and found that teachers were avoiding nonfiction—especially science books. Yet when children were asked what genres they wanted, they were highly interested in nonfiction. Following these discoveries, nonfiction has been added to widespread curriculum guidelines and seen greater demand from educators. Publishers have met this demand with increasingly high-quality nonfiction books.

With a little faith in children’s own interests and a little confidence in the appeal of the genre, science fiction for children can turn the same corner. Label science fiction as science fiction. Tell kids when they’re reading science fiction. And, above all, write and publish more high-quality science fiction for young readers.
