Five Awesome Science Fiction Tropes

In each genre, there are conventions that readers expect to find. Romance, Fantasy, Science Fiction, Historical Fiction, General Fiction, non-fiction, and the rest each have norms that define them. This information helps readers decide whether he or she might be interested in a book, and helps the storytelling along. So, there is both a marketing piece and a storytelling piece to genre conventions.

I find genre and genre conventions interesting because as I have studied what’s inside each category, I have been surprised by the innovative ways authors create around these same few topics. How many different ways can we encounter two people who fall in love? How much can we say about time travel? There are many, many ways to explore these same ideas.

Science fiction has distinct narrative tropes and conventions that readers expect to find when a work is categorized as science fiction. Below I’ve highlighted five features/topics/themes that readers expect their science fiction narrative to grapple with and explore.

  1. Artificial Intelligence: The central question in a story that features AI is what differentiates humans from machines? Examples include Her, Blade Runner, Westworld
  2. Technology: The central question is usually ethics. Just because we can do something, should we? Examples include Jurrasic Park, Stranger Things
  3. Aliens: The central question: if we are not alone, then are humans special at all? Examples include Arrival, Hitchhiker’s Guide to the Galaxy, Axiom’s End
  4. Space Travel: We are so small and insignificant in the vastness of the universe. Examples include The Martian, Alien
  5. Time Travel: The central question is one of identity, do I possess free will, or is my path pre-determined? Am I a result of my experiences? Examples include Loki, Avenger’s Endgame, Replay, Back to the Future

I find that some of these central questions overlap, such as Space Travel and technology and Aliens or Technology and AI. In future blog posts, I hope to unpack different ones and review what elements bring out the central question and what works failed to do so. At a glance, Stranger Things doesn’t quite pose the question to the audience on whether the government should have made the “upside-down” in the first place. But maybe they cover this in subsequent seasons that I have yet to watch.
