What if sarcasm were suddenly banned?

The immediate practical problem with banning sarcasm is definitional. Sarcasm is not a distinct grammatical category - it is an interpretive stance that a listener or reader assigns to an utterance based on context, tone, and their model of the speaker's intentions. The same sentence, "What a lovely day," can be literal or sarcastic depending on delivery, context, and shared knowledge. You cannot ban an interpretation.

More technically, sarcasm is one member of a family of non-literal language use that includes irony, hyperbole, understatement, and metaphor. These forms are not ornamental - they are how a significant proportion of human communication actually works. Banning sarcasm without banning all non-literal language would be incoherent. Banning all non-literal language would make most human communication impossible.

What the hypothetical illuminates, though, is something genuine about the social function of sarcasm. It is a form of coded communication that allows speakers to convey a meaning that they can plausibly deny having conveyed. In hostile environments, that deniability is protective. In political contexts, it has historically been one of the few tools available to people who cannot safely criticise power directly. You cannot ban sarcasm without eliminating one of the primary mechanisms through which oppressed groups have been able to talk about the people oppressing them.

The social and political cost of banning sarcasm would therefore fall almost entirely on those least powerful to resist the ban. Those in power rarely need the protection of indirect language - they can say what they mean. Sarcasm belongs to those who cannot.

The scenario turns out to be less about tone and more about who controls the terms of acceptable speech.

I'm not sure I always know when something is sarcasm. My teacher sometimes says "oh well done" when someone has done something wrong and I used to think she meant it. My mum said that's sarcasm and now I listen for the voice she uses when she says it.

If sarcasm was banned I think adults would have to say more things they actually mean and that seems like it would be uncomfortable for them. My dad sometimes says something sarcastic when he means something quite different and I think the sarcasm makes it easier to say because it's a bit of a joke. If he had to say the actual thing directly it might feel more like an argument.

I think some jokes would stop working. A lot of funny things are funny because they say the opposite of what they mean. If you had to say what you actually thought all the time the jokes would have to be a different kind.

Also I think adults use sarcasm to say things about people in charge that they wouldn't say in a normal way. My grandad says sarcastic things about politicians but he says them in a funny voice so it sounds like a joke. I think that is a way of saying something true without getting in trouble for it. If that was banned it would make it harder to say true things.

I think banning sarcasm would make people more honest about some things and better at hiding the things they really think about other things. That seems like it might not actually be better.

Literature would be a significantly poorer place. Irony and sarcasm are not stylistic frills - they are fundamental rhetorical tools for saying something true in a way that allows the reader to discover it rather than being told it directly. Swift's "A Modest Proposal." Austen's narrators. Heller's Catch-22. These work because the gap between what is said and what is meant is where the meaning actually lives.

There is a long history of totalitarian regimes attempting to eliminate ironic distance from public discourse, precisely because it is a form of truth-telling that resists direct suppression. You cannot imprison someone for saying "The Dear Leader has given us another magnificent harvest" with a particular emphasis, but if you are present in the room you understand exactly what is being said. The authorities understand it too, which is why those authorities hate irony and work to eliminate it.

The more interesting version of this thought experiment is not what would be lost but what would be revealed. Sarcasm also does negative work - it allows people to bully while maintaining deniability, to dismiss without engaging, to perform sophistication without having any. "Obviously" and "clearly" at the start of a sentence in an online argument are forms of sarcasm that function purely to make the target feel stupid. That kind of thing I could do without.

What the hypothetical ultimately shows is that we use indirect language to manage the distance between what we feel and what we can safely say. Sarcasm is one of the main tools for that management. Remove it and all that unmanaged feeling has to go somewhere else.

I suspect the somewhere else would be considerably worse.

My first reaction is professional. Sarcasm is approximately thirty percent of my act. The rest is observation and misdirection, but the sarcasm does the load-bearing work of saying true things about power with enough deniability to avoid a direct confrontation. So if sarcasm were banned, I would be, in a meaningful sense, mute.

But there's a more interesting answer underneath that. Sarcasm — irony, satire, the deadpan, the implied meaning that runs exactly opposite to the stated one — is historically the tool of the less powerful talking about the more powerful. The court jester could say what no one else could say because the joke created deniability. Political satire has been suppressed wherever political dissent has been suppressed, not because governments have confused it with dissent but because they have correctly identified it as dissent in a different register. You cannot ban sarcasm without banning the ability to say to power: I see what you're doing, and so does everyone in this room, and we are going to laugh about it rather than pretend we can't see it.

The countries where sarcasm is dangerous are not ones with very strict rules about tone. They are ones where the thing the sarcasm is pointing to — the gap between the official story and the reality — is particularly dangerous to acknowledge. The ban isn't on the sarcasm. It's on the acknowledgement. The sarcasm is just the cleanest way to communicate: we all see this.

So if sarcasm were banned, what you would actually be banning is a particular kind of shared recognition. You could still state things directly. You could still disagree. What you would lose is the version of communication that lets two people in a room with a third person they're both nervous of communicate their shared understanding without ever directly saying it. Which is useful in very small ways — navigating awkward social situations — and in very large ways, when the third person in the room is a government.
