Thank you, psul, for the mention! Here's a bit more on what's going on, regarding compulsions:
Narrative and story drive the action. Ultimately, narrative is about the choices we make, and the consequences of those choices. For example, SCP-2875 works not only because it's a story about too many bears, but also because the city council ended up choosing too many bears. Unfortunately, compulsions hijack choice. As a result, the narrative, in most cases, ends when the compulsion occurs.
Take SCP-012 for example, possibly the oldest compulsion on the site. In a vacuum, it doesn't kill you when you finally bleed out. It kills you when you look at it. Therefore, the story ends when the subject views it. We know how it goes from there. That's why things like experiments that prevent death from coming to the subject, or explorations into the subject's psyche that show that there are still decisions being made from within the compulsion help to strengthen the story.
So, many poor compulsions end up killing the story too soon in an attempt to increase the horror of an item. Yet horror can only exist when there's a choice to be made. There's nothing to fear when it doesn't matter what you do. So, many compulsions end up killing the horror when they kill the story.
How can a compulsion be used to good effect? There are a few ways.
- Recognize that the compulsion ends the story for a subjected character. This is mentioned specifically in SCP-571 and SCP-2310. As a result, the story revolves around what those who aren't under the compulsion do.
- Don't let the compulsion completely remove choice. SCP-2737 forces emotions on someone, but they are still free to choose how they act. SCP-586 forces people not to get it right, but there are still plenty of ways to be wrong.
- Let it be possible to become free of the compulsion. Amnestics are a common solution used for this. SCP-2852 doesn't affect everyone identically afterward. The story might still end for someone under the influence of the compulsion, but if other people can save that person, then there are still decisions to be made and story to be had.
This was all part of how I designed the compulsions in SCP-2459. I wanted to make sure that those affected were still fully capable of interaction, meaningful contribution, decision making. They won't leave the road, but you can still converse with them, coordinate humanitarian efforts with them, and they're all interacting with each other, redesigning their situation, and still doing all the things people do. In that way, they're still driving story. They're still making choices.
For all the new authors out there: compulsions are okay, as long as there's still someone involved able to make meaningful choices.
