Realistic 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).
