Dark humor: what it says about your intelligence

At the wake after their grandmother's funeral, Nathan sat opposite his aunt and announced to the whole table that grandma would have taken these sandwiches apart so mercilessly the room would have gone red. Half the table froze. The other half was visibly relieved, and Hannah laughed first, only to feel awful about it a second later.

The difference between those two reactions had nothing to do with who had loved their grandmother more. It was about what each of them still needed to do with the loss: one needed to keep it solemn a while longer, the other needed to breathe. A single sentence gave the whole table away inside a second.

Dark humor is a subject, not a style

Dark humor is the name for laughter aimed at the things that frighten us: death, illness, disaster, our own ending. It is not the way you joke but the material you build the joke out of. That distinction gets muddled almost constantly.

Humor styles describe the address, not the subject matter. Do you joke with people, quietly for yourself, at somebody else's expense, or at your own? Dark humor can be told in any of those four registers, kindly or cruelly, pointed outwards or inwards. The overview of the four humor styles goes through them; here one point is enough: a grim subject on its own says nothing about whether the joke is warm or nasty.

Nathan's line about the sandwiches was aimed at the absurdity of the occasion, and a little at his grandmother, who would have enjoyed it herself. Had he used the same tone on the aunt who had spent all morning making those sandwiches, it would have been sharp humor at one specific person's expense, and the subject of death would have changed nothing about that. Dark material and an attack are two different things that simply keep meeting in the same room.

Why does taboo work so well as fuel? A joke needs two things at once. Something that threatens or breaks a rule, and a signal that here and now nothing bad is actually going to happen. The bigger the first, the bigger the relief when the second arrives, and death is the largest breach of the rules we know of.

An uncomfortable consequence follows. The best material sits exactly where the subject is most tender, so the distance between "that landed beautifully" and "that was a misstep" is a couple of words wide. Anyone joking about heavy things works without a net, best intentions included.

What Willinger and his team found

In 2017 Willinger and his colleagues published a result that has been quoted ever since, usually inaccurately. They gave people dark humor and watched two things: how well they understood it and how much they enjoyed it. To that they added intelligence tests and measures of aggressiveness.

The people who understood dark humor best and enjoyed it most scored higher on the intelligence tests. And lower on aggressiveness, which is the surprising part. You would expect the opposite: that grim jokes are the delicacy of whoever brings more edge than consideration to other people.

It makes sense once you look at what a joke like that asks of the listener. You have to hold two incompatible readings of one sentence at the same time, notice which rule has just been broken, and know throughout that none of it is meant literally. Anyone who loses the thread hears only cruelty. Anyone who follows it hears construction.

Now the honest footnote. This is a correlation, not a cause, and it is one study. It does not follow that the acquaintance who fires off grim one-liners is smarter than you, nor that dark humor makes anybody smarter. What was measured was comprehension and enjoyment, not the ability to invent the joke. The broader question of whether funny people really think faster gets a piece of its own on humor and intelligence.

One more thing came out of those numbers differently from what almost anyone would predict. A taste for the grim joke did not behave there like an expression of hostility. It looks more as though people who can play with horror at the level of words have less need to wrestle with it elsewhere.

Gallows humor: why the ambulance crew laughs

Ask anyone from an ambulance crew, a fire station or an emergency department what the conversation sounds like on the way back from a bad call. Most will tell you they laugh there at things nobody would say out loud outside. This is gallows humor, and the name is meant literally: it describes the laughter of people standing in front of something they can do nothing about.

A bystander who catches that conversation usually reads it as cynicism. That is a mistake about the addressee. The joke is not aimed at the person being carried but at the situation, at the absurdity of the circumstances and above all at the crew's own helplessness. It is a way of taking back, for a moment, a scrap of control over something that took all of it.

It has a fairly practical function too: the crew goes out again within the hour. Anyone who lived every call through to the last drop would stop going out at all inside six months. Laughter in a closed circle also works as a quick check that everybody is still fit to carry on. Nobody asks "how are you holding up", somebody says a line, and who joins in tells you everything.

What decides it is the target and the audience. People in the caring professions know that difference by instinct, and it carries over into ordinary life.

The last row is where gallows humor stops being a valve. As long as the joke points at the situation, it holds people together. The moment the target becomes whoever is suffering most inside it, it turns into something else, and the closed circle usually notices before the person who made the joke does.

Hospitals and fire stations are not alone in this. The same mechanism runs in a team on its third night rebuilding a collapsed system, and between the parents of a child with a serious diagnosis. Wherever the stakes are high and there is no way to move them, humor appears that sounds improper from outside and keeps people upright from within.

Valve or escape

George Vaillant, who spent decades tracking how people come to terms with what life hands them, files humor among the mature defense mechanisms. By mature he means something precise: it lets you keep seeing the unpleasant thing, you need not deny it, and nobody else pays for it. Denial would hide it, anger would hand it to somebody else, a joke leaves it where it is and takes some of its size away.

Yet the same joke can also be the way you never get to the thing at all. The line between the two does not run through the subject or through how harsh it is, it runs through timing. The difference is between "say it seriously and then make a joke of it" and "make a joke of it instead".

There is one reliable way to tell: whether a version without the punchline exists. When the people around you know your illness, your divorce or your firing only as a series of jokes, nobody will ask how you actually are. From where they stand, you have already told them. They stop asking before it dawns on you that you never said it.

Try answering honestly: when did you last talk out loud about something heavy and fail to smuggle a single relieving line into it? If nothing comes to mind, that need not mean anything dramatic. It is worth knowing that the joke is a default setting for you rather than a choice. How humor works as a defense, and when the support turns into a trap, is taken apart in the piece on humor as a defense mechanism.

The line runs through the audience, not the subject

The commonest advice is "some subjects are off limits", and in practice it does not work. If it held, whole industries where death gets joked about daily and nobody minds could not exist. The same sentence passes in one room and not in another, though the words are identical.

What decides it is mostly distance, and there are two kinds. Time: how fresh the wound is. And personal: how close the listener stands to it. Someone in the middle of a disaster stands at a different distance than a colleague three floors up, even when both meant the same thing.

From that comes a rule that groups keep almost on their own, without anybody stating it: permission to joke belongs to whoever is paying for it. A patient may say things about their own diagnosis that would be unbearable coming from a healthy visitor. It has nothing to do with who is funnier and everything to do with who carries the consequences.

The new complication is that closed circles hold badly now. A sentence that would once have stayed in the locker room can be photographed and passed on, and outside its original audience it loses its context. A screenshot cannot show who was sitting there, who had just come back from the worst call of the week and why everyone heard it as relief.

The practical test takes a second, before you let the sentence out. Who is sitting here, and who does this touch more than it touches me? When you do not know the answer, let the joke be told by whoever it touches most. Silence at a moment like that is not a sign of boredom, it is a reading of the room.

If you are curious where your own humor usually points, whether it connects people, protects you or goes looking for a target, a short humor styles test gives you a bearing. It asks about ordinary situations, and its result is worth taking as a description of a habit you can work with rather than a verdict on your character.

Hannah laughed first at that table and it bothered her all afternoon. Three months later she caught herself telling a friend the line about the sandwiches, and for the first time she talked about her grandmother for more than a minute at a stretch. The joke was not what took her grandmother away. It was what brought her back into the conversation.
