No two authors are alike, and no author is alike over time. This is excellent, as the audience isn’t a monolithic block either, and wants different things, too. And… then there’s infodumps.
All stories require a certain amount of information to be conveyed, and context for the story. In stage plays, there was once a convention to open the story with two characters, often the maid and butler, gossiping and giving us the backstory. Which led to the “Maid and Butler” dialogue, also called “As you know, Bob.” (Link is to TV tropes.)
There’s also the prologue, wherein the information is presented as “So far in this series…” or “This story is set on a world with the following pronunciations, tribes, history, or deadly dangers not known on earth…” (Very popular in the 80’s)
Times and tastes change, and now the general standard is to work this information into the story instead of presenting it in a chunk of front. Otherwise know as, you can’t get the people to learn about the story unless they care about the characters.
Working in, though, has a range between Heinleining and Infodump. On the one end, Heinlein was famous for working the worldbuilding into small details and conversation. How do you know you’re on a space station in the future? Well, “the door dilated” instead of the door opening. On the other end is putting the information into huge chunks between dialogue or action. This can be done very well, though if you get known for it, you too may end up parodied by your fans, like “How David Weber Orders A Pizza.”
Most authors are usually somewhere inbetween. I personally don’t like infodumps; they make my eyes glaze over. Jim Curtis, over there leaning against the back wall, is laughing his head off because I beta-read for him… and he’s well-used to seeing anything over a line or two marked on the side of his draft as “infodump; skimmed this”, or “got bored here.” Fortunately, he 1.) doesn’t take it personally, and 2.) knows that most readers are not like me!
(And if you want a neat little story about dealing with an alien invasion while you’re trying to set up a contraband still, check out Rimworld: Stranded. He’s getting close to releasing the follow-up novel, so you won’t have to wait long for more great stories in that galaxy!)
When I put out my first story, I almost went with no infodumps at all. (There are a few worked in, because beta readers got confused.) And it shows: there are two running themes in the reviews. Some readers say that they liked how there were no infodumps, and that you got to have the world unfold as you read… and the other readers say that they got confused on a couple points, and would have had a better time if that info had been dumped in up front!
Clearly, this means you want to sneak information in earlier and better than I did. Where do you tend to end up on the imparting information scale? How do you prefer to do impart yours: dialogue, exposition, scene building, prologue, or bits of narrative summary?
