This is partly based on things I've written in #WritingWithDice, parallel concepts I later found in the Location Crafter, and ideas that I read in The Writer's Journey. As I find better ways elucidating on it, the document will evolve.
Feel free to leave feedback, ideas, etc in the comments, or anonymously if you prefer. I very much appreciate it since I'm interested in finding ways in which tools can incorporate this.
Defining Baseline Assumptions
I define baseline assumptions as details that ones expect to be a normal aspect of a particular “thing” (i.e. a situation, a location, an entity, a setting, etc). These details would not be remarkable in the context that this “thing” would normally exists. In terms of solo play, these things might merit a passing mention at best, if at all.
For example, in most game situations, you wouldn’t remark that an NPC has two legs as that would probably be a given. If you’re describing a dance club, the thumping music might merit a passing mention here and there, but you would not likely place your focus on it.
