Trust the reader to keep up
An expository dump (or info dump) is a “a very large amount of information supplied all at once, expecially as background information in a narrative.” That’s a rather academic definition, and like most language definitions, it contains subjective terms. Exposition is simply text that explains something. Narratives need a certain amount of exposition to work. What I object to is large chunks of explanation that stops the action of the story. For example, a few years ago I wrote about a fantasy novel I stopped reading because the third or fourth chapter of the book consisted entirely of one character lecturing another about the history of the world. That’s sloppy writing, at best.
I don’t have anything against exposition, per se. There’s a lot of expository writing in some of my favorite novels. Just earlier this week, for instance, I was reading in Nisi Shawl’s novel, Everfair (which is a non-eurocentric steampunk novel, so far), a description of a small train. The description gave us some hints of how the fictional world’s technology differs from our own history, gave us a sense of not just the look of one of the supporting characters, but his personality, and also had hints about the social strata of the country which the viewpoint character was visiting. But this wasn’t a long passage. It was only two paragraphs. And rather than prattling on for pages about the history of the country, it gave us a few tidbits of information from which we could infer more. And it isn’t just description. Something is happening: a supporting character is arriving to some anticipation of the viewpoint character.
In my own writing you will find very little exposition. To me, the heart of any story are the triumphs, failures, hopes, and fears of the characters moving through it. Yes, I’ve done a lot of world building. If you ask, I can go on an length about all sorts of things in the history of the fictional world where my fantasy novels are set. I have to know all of that stuff to tell stories. But most readers are interested only in a fraction of it.
No one wants to read a scene in which one character prattles on about how ten years ago when the previous emperor died, a group of traitorous nobles assassinated several of the heirs in an attempt to grab the throne for themselves, including the motives of each of the conspirators, who died and who survived. When it was important to the plot I’m writing now, I had one character mention “the succession crisis in the capitol year ago.” There was another point where that history was relevant to the reason one character was hostile to another, and was able to have just a few lines of the argument between those characters give a few more details. But those lines also moved the plot point that was happening right that moment along, and gave the reader some insight into the personalities of the two arguers (as well as a couple of other characters who were trying to get them to stop arguing and deal with the problem at hand).
I do that because I trust that readers are smart enough to put pieces together and build their own picture of the world. I don’t need the reader to visualize exactly how the stitching on a character’s clothing looks, or the precise shape of the filigree on a particular piece of furniture, or to keep track of which pillows are round and which are square in order to follow the story.
If I wanted to tell the story of the succession crisis, I would make the crisis itself the story. I’d pick one of the characters involved as my protagonist and tell the tale. But if it’s backstory, we don’t need all the details. Sure, it’s handy to know that in the present timeline, one particular vampire-like character was one of the failed conspirators who was cursed by someone who loved one of the murdered heirs (hey, it’s a fantasy universe, why can’t we have a good curse every now and then?). That tells you how the character wound up an evil parasitic undead, and gives you some hints as to how trustworthy he is going to be to his alleged allies in the current story. It may also help the reader understand his motives at later points in the tale. But I was able to convey that in a couple of lines of dialog and keep moving on with the current tale.
Not everyone is as comfortable without all the details as I am. I understand that. And there’s a part of me that always worries that I haven’t given readers enough clues. So sometimes I do something like write a whole chapter worth of flashback, which I read and re-read and argue with myself about whether it’s really needed and do I really want pull the reader out of the current story.
And eventually I usually figure out that if I tweaked some dialog over here, and add a small scene where two characters who weren’t aware of the past events find some of the aftermath, and realize that yes, I should trust the reader to figure it out and move those flashbacks over into my big file of background information that the reader is never going to see.
Because part of trusting the story is trusting the reader to not just to follow it. I want the reader caught up in the story I’m telling right now. I want the reader turning the pages as quickly as they can, breathlessly asking, “And then what happens?”
