““Laughter, then, shows us the boundaries that language is too shy to make explicit. In this way, humor can be extremely useful for exploring the boundaries of the social world. The sparks of laughter illuminate what is otherwise murky and hard to pin down with precision: the threshold between safety and danger, between what’s appropriate and what’s transgressive, between who does and doesn’t deserve our empathy. In fact, what laughter illustrates is precisely the fact that our norms and other social boundaries aren’t etched in stone with black-and-white precision, but ebb and shift through shades of gray, depending on context. For this task, language just doesn’t cut it. It’s too precise, too quotable, too much “on the record”—all of which can be stifling and oppressive, especially when stated norms are too strict. In order to communicate in this kind of environment, we (clever primates) turn to a medium that gives us “wiggle room” to squirm out of an accusation, to defy any sticklers who would try to hold us accountable.””
