All fiction can be said to present a simulated reality to the reader, viewer or player. Humans purposely experience these things and enjoy them, while knowing they are not actually real. As humans only respond emotively to things we believe to be real, this phenomenon has become known as the "
paradox of fiction". The idea of a "
willing suspension of disbelief" was first proposed in 1817 by
Samuel Taylor Coleridge in order to explain this discrepancy. Others have noted that the way the story is told can override people's belief in the unreality of the story by engrossing them in the narrative. The concept of a simulated reality is in itself a common
science fiction trope, often a
metaphor for complacency towards the influence of modern technology, corporations, and other societal forces on one's behavior and desires. One of the most well-known examples is the 1999 film
The Matrix. The film, and its ensuing media franchise, depicts far-future humans being harvested for
bioelectricity by intelligent machines while living in a false, computer-generated approximation of late 20th century Earth. Some humans seek to break others out of the simulation, offering them a choice between a
red pill and blue pill that will set them free or keep them in the Matrix forever. Escaping the simulation is usually presented as the correct choice, even if reality is harsher and more displeasing, reflecting the desire of humans to live in an
objective reality. However, the idea that objective reality would be definitively superior has been debated. Other prominent examples of a simulated reality in fiction include
The Truman Show (1998), in which a man realizes he is actually living in a massive television set in which actors take the role of real people, and
The Thirteenth Floor (1999), a neo-noir film about a murder investigation related to a virtual reality world, in which doubts about reality itself emerge. In the
TRON franchise, a simulated reality called "the Grid" is populated by programs which appear in the likeness of the programmer who created them. People who are "beamed" into the Grid are able to interact with these programs and their digital surroundings. == In real life ==
