Fiction
Speculative versus realistic fiction

The umbrella genre of speculative fiction is characterized by a lesser degree of adherence to realistic or plausible individuals, events, or places, while the umbrella genre of realistic fiction is characterized by a greater degree. For instance, speculative fiction may depict an entirely imaginary universe or one in which the laws of nature do not strictly apply (often, the sub-genre of fantasy). Or, it depicts true historical moments, except that they have concluded in a completely imaginary way or been followed by major new events that are completely imaginary (the genre of alternative history). Or, it depicts impossible technology or technology that defies current scientific understandings or capabilities (the genre of science fiction).

Contrarily, realistic fiction involves a story whose basic setting (time and location in the world) is, in fact, real and whose events could believably happen in the context of the real world. One realistic fiction sub-genre is historical fiction, centered around true major events and time periods in the past. The attempt to make stories feel faithful to reality or to more objectively describe details, and the 19th-century artistic movement that began to vigorously promote this approach, is called literary realism, which incorporates some works of both fiction and non-fiction.
