I am referring to this:
• Could a joke be funny enough to kill?
I actually liked this question. We don't see much describing its placement in its world, but it was my understanding that most people here didn't need for such information to be presented up–front.
Does it seem like the asker is fishing for people to do the work of story–writing for them?
Maybe. As it is now, methinks that would be obvious only with the finished product.
If the plot device is just a throwaway to contrive some tension, then yes. Perhaps the author has several clever ideas and a clear progression of character, whether a lethal joke is possible or however it could actually work, but they simply want to know if the core premise is plausible prior to proceeding.
Maybe they know social psychology well but not physiology.
