This is the principle of the Chekhov’s gun: that all items within a narrative must contribute to the overarching narrative itself, and those that don’t should be removed. This is very, very true of the first two Harry Potter books, where J.K. Rowling includes seemingly random bits of information in the first half of each book that, voila, suddenly reappear during the climax in important ways. (Examples: Quirrell’s turban and the Whomping Willow). Thankfully, Rowling’s writing improves significantly from the third book, where the Chekhov’s guns are more subtly introduced, and don’t always stay out of sight before being revived for the grand finale.
However, does the Chekhov’s gun have a place in a science article?
Most writers, editors and readers (I suspect) would reply in the affirmative. The more a bit of science communication stays away from redundancy, the better. Why introduce a term if it’s not going to be reused, or if it won’t contribute to the reader understanding what a writer has set out to explain? This is common-sensical. But my concern is about introducing information deftly embedded in the overarching narrative but which does not play any role in further elucidating the writer’s overall point.
Consider this example: I’m explaining a new research paper that talks about how a bunch of astronomers used a bunch of cool techniques to identify the properties of a distant star. While what is entirely novel about the paper is the set of techniques, I also include two lines about how the telescopes the astronomers used to make their observations operate using a principle called long baseline interferometry. And a third line about why each telescope is equipped with an atomic clock.
Now, I have absolutely no need to mention the phrases ‘long baseline interferometry’ and ‘atomic clocks’ in the piece. I can make my point just as well without them. However, to me it seems like a good opportunity to communicate to – and not just inform – the reader about interesting technologies, an opportunity I may not get again. But a professional editor (again, I suspect) would argue that if I’m trying to make a point and I know what that point is, I should just make that. That, like a laser pointer, I should keep my arguments focused and coherent.
I’m not sure I would agree. A little bit of divergence is okay, maybe even desirable at times.
Yes, I’m aware that editors working on stories that are going to be printed, and/or are paying per word, would like to keep things as concisely pointy as possible. And yes, I’m aware that including something that needn’t be included risks throwing the reader off, that we ought to minimise risk at all times. Finally, yes, I’m aware that digressing off into rivulets of information also forces the writer to later segue back into the narrative river, and that may not be elegant.
Of these three arguments (that I’ve been able to think of; if you have others, please feel free to let me know), the first one alone has the potential to be non-negotiable. The other two are up to the writer and the editor: if she or they can tuck away little gems of trivia without disrupting the story’s flow, why not? I for one would love to discover them, to find out about connections – scientific, technological or otherwise – in the real world that frequently find expression only with the prefix of a “by the way, did you know…”.
