This article describes findings from an online survey Science Fiction & Fantasy: Your Experiences, launched in November 2015 and closed 1 year later, which received 909 unique responses. The survey identified characteristics of readers of science fiction, their knowledge and experiences of works, authors, and subgenres. It examined their attitudes to science and science fiction and their judgment of the similarity between real and fictional scientists. Contrary to declining reading habits, the science fiction and fantasy audience read consistently high volumes of books, as well as watching genre TV and film. We discovered that reading science fiction and fantasy may have a role in sustained, and cognitively beneficial, adoption of reading by young people and is complementary to other forms of consumption, rather than competitive. Science fiction was also found to be an important influence on the perception and acceptance of science by the public. Implications of this are that science fiction and fantasy are now a normal part of life for a wide range of people, and science fiction has a positive influence on popular interpretation, acceptance, and support of scientific endeavors. These results support earlier work that suggests science fiction is a valuable research tool for public engagement with science.
