Questions: Science Fiction: Speculation and Extrapolation

Question 1

A novel imagines a future world where people live on floating sky-cities. The world is internally consistent, visually inventive, and emotionally compelling — but the sky-cities are never connected to any observable trend in architecture, energy, or urban planning. By the standards of rigorous SF, what is missing?

• A. Word-building detail — the setting needs more specific geography and culture
• B. Extrapolation — the premise has no grounding in a real present-day trajectory that is being extended
• C. Conflict — the absence of tension makes the world feel implausible
• D. Historical analogy — all good SF should mirror a historical moment

Answer: (B)

The key distinction the topic draws is between extrapolation (taking a real variable and following its logic) and mere imagination (inventing a future without grounding it in the present). Sky-cities as pure invention may be compelling fantasy, but rigorous SF earns its speculative authority by extending something actually observable — a technological, social, or scientific tendency — into its consequences. World-building detail and conflict matter, but they're not the missing ingredient here.

Question 2

Ursula K. Le Guin imagines a planet with no gender. A student reads this as a prediction about future humanity. What does the student misunderstand about how SF's 'novum' functions?

• A. The student underestimates Le Guin's commitment to scientific plausibility
• B. The novum is a lens on the present — it defamiliarizes what we take for granted now, not a forecast of what will come
• C. The student should focus on character rather than world-building elements
• D. SF novelists never intend their speculative elements to have real-world relevance

Answer: (B)

The Explainer makes explicit that SF uses the future to defamiliarize the present — to reveal the contingency of arrangements we treat as natural. When Le Guin imagines a genderless society, the purpose is to illuminate what our current gender structures look like when we step outside them, not to predict a genderless future. Reading the novum as prediction misses its rhetorical function as a mirror held up to the present.

Question 3

The internal consistency of an SF world's speculation is a reliable quality test: if every element follows from the original 'what if' with logical necessity, the SF is doing its job well.

• T. True
• F. False

Answer: True

The Explainer explicitly uses this criterion: 'The best SF is coherent in its speculation — every element of the world flows from the original what if with something like logical necessity.' When consistency breaks down — convenient exceptions, ignored implications — it signals either a failure of imagination or a choice to prioritize other values over rigorous extrapolation. Tracking this consistency is the starting point for serious SF analysis.

Question 4

What distinguishes SF from fantasy is that SF involves technology while fantasy involves magic.

• T. True
• F. False

Answer: False

The topic locates SF's distinctiveness in its method — disciplined extrapolation from observable present-day variables — not in its surface content (technology). A story involving advanced technology but no grounding extrapolation is closer to fantasy in this framework. Conversely, an SF work might extrapolate social trends with no technology at all. The genre distinction the topic establishes is epistemological (how the imagination is disciplined), not thematic (what objects appear in the story).

Question 5

What does it mean to say that SF's speculative element is a 'novum,' and what is its primary function in rigorous SF?

Model answer: The novum is the science-fictional element that makes the story's world different from ours — the new thing (a technology, social structure, physical law, etc.) introduced by the extrapolation. Its primary function is to defamiliarize the present: by imagining a world with that element, the author makes us see our own world from outside, revealing what we normally take for granted as contingent rather than necessary. It is a lens on the present, not primarily a prediction about the future.

The term novum (from Darko Suvin's theory of SF) captures exactly why the speculative element is not just window dressing — it is the argumentative core of the work. A good SF analysis asks: what is this novum extrapolated from? What present-day feature does it reveal or interrogate? Treating it as mere setting or plot device misses why SF is a 'rigorous literary form' rather than escapist fantasy.
