In Jokes and Audience Gatekeeping
Launch library · evergreen read
In jokes work because understanding them signals membership in a specific group, while missing them just as clearly signals that you are outside it. That dividing line is not usually built deliberately, it emerges naturally from shared history that not everyone has had the chance to actually witness firsthand or follow closely enough.
This creates a quiet form of gatekeeping, where a joke does real work sorting an audience into insiders and outsiders, even though nobody explicitly decided who belongs. The joke itself is often simple, its power comes entirely from the context surrounding it and everything that came before this particular version of it.
Communities sometimes deliberately preserve this friction, resisting the urge to explain a running joke because the explanation would flatten it entirely. Part of the pleasure of an in joke is that it stays slightly inaccessible to anyone who has not put in the time to actually follow along closely enough to catch it.
