Serious Work Does Not Require a Serious Face

A four-year-old laughs around 300 times a day.* By the time that same person turns forty, they are doing well to laugh 300 times in two and a half months.

Stanford Graduate School of Business researchers Jennifer Aaker and Naomi Bagdonas have a name for this. They call it 'the humour cliff', and the data behind it comes from a Gallup survey of 1.4 million people across 166 countries.

The drop starts sharply around age twenty-three, roughly when most people start getting serious about their profession, promotions, earnings, the rent or the mortgage that needs paying.

The notion of demonstrating the taking the work seriously, often comes at the cost of remembering that one does not necessarily always need to take themselves as such.

That is not a coincidence. That is a trade-off.

Somewhere in that shift from student to professional, a lot of people quietly decide that levity and seriousness cannot coexist.

Levity simply means playfulness, light-heartedness, the willingness to let a moment be lighter than it strictly needs to be.

Laughing less starts to feel like part of growing up, part of being taken seriously, part of the job.

Hiroki Asai ran Apple's Creative Design Studio for years. He put it more bluntly than most: "Fear is the greatest killer of creativity, and humour is the most effective tool I've found for keeping fear out of a culture."

Enhancing levity in teams is not a nice-to-have. It's a potent defence mechanism, deployed against the dry, overly-serious element that actually stops the best work happening.

Most workplaces have the relationship backwards. They treat seriousness as the marker of competence and humour as the thing you allow once the serious work is done.

The research, and my own insights from well over a decade making television shows followed by fifteen years watching comedy rooms as a stand-up MC, says the opposite is closer to true.

Comedy clubs are an extreme version of something most workplaces already run on: a group of people deciding whether they trust the person in front of them enough to lower their guard.

Defences down, people contribute more honestly. They take small risks. They admit when something is not working before it becomes a bigger problem. Far less of that happens in a team that has decided seriousness is the only acceptable register.

In a place with levity as a theme, harsh responses to ideas or errors are mitigated. People are freer to try things, experiment, to connect. Loosening that weight is one of the easiest wins available to most teams.

A meta-analysis of 49 separate studies, covering more than 8,500 participants, found that positive humour reliably strengthens both resilience and group cohesion. Leaders who use it well are seen as more motivating and more approachable. Not despite the humour. Because of it.

Acts in a comedy club aim high. If the funniness of a joke can be marked out ten, with then the highest, then they are mainly aiming nines and tens, every few seconds, by design.

A workplace should never be aiming anywhere near those lofty heights, and trying to is usually where things go wrong.

What a workplace actually needs sits much lower on that same scale. A one, a two, a three. A small warm aside. A shared groan at something everyone in the room recognises. Nobody needs a routine.

They appreciate when the room, and the people in it, feel a little lighter than it did a minute ago. 

This has limits, and the limits matter more than the technique. Levity that works draws on common ground, the shared, slightly absurd experience of being in that meeting, that industry, that Monday morning... it should be employed cautiously when referring to individuals.

Appropriateness is an essential theme.

The moment humour singles someone out based on ethnicity, gender, religion, even gently, even as a joke clearly meant kindly, it stops being levity and starts being exactly the thing that makes a room less safe rather than more.

That is not a small distinction. It is the entire difference between humour that builds trust and humour that quietly destroys it.

The safest, most reliable territory is the shared and the absurd: the meeting that overran for no reason anyone can explain, the system that everyone privately hates, the universal indignity of a video call with someone's microphone still muted. Nobody loses anything by laughing at that together.

If someone in the team can naturally bring something sharper, more daring, genuinely funnier, wonderful. 

The wins are built on the low-hanging fruit nearly everyone can reach. Like adding some character and humour to an out-of-office message, and other common opportunities.

Far better than the occasional big swing that might land brilliantly or might land very badly indeed.

Levity is not a personality trait reserved for the office extrovert, and it is not the same thing as trying to be funny on demand, which tends to produce the opposite of warmth.

Levity is an attitude. It's more about being playful than being hilarious. Light-heartedness is the name of the game.

It's all easily understood when opportunities for applying it are highlighted. Even better when examples and techniques are shared.

In fact, the range runs not just to creating a smile, or even laughter. How one is seen to respond to a little humour is all-important.

Opportunities abound in how you open a meeting, how you respond when something goes wrong, how much room you leave for a colleague's small joke to land before steering back to business.

Comedians consider versions of this constantly. Read the room. Lower the temperature when it needs lowering. Know exactly how much lightness a particular moment can carry before it tips into something unhelpful.

This is one more place where the gap between AI and a genuinely skilled human shows up. AI can generate a joke, usually not a very good one, as a matter of routine.

AI cannot read a facial expression, or a room, and know whether a particular moment can carry lightness or needs space to be serious instead.

I have written elsewhere about what AI cannot replace, and that judgement is just one of many key advantages that humans still hold.

Humour is a human skill. Levity, playfulness, is for people.

A survey of more than 700 chief executives found that 98 percent prefer job candidates with a sense of humour, and 84 percent believe people with a sense of humour do better work.

Employees who rate their leaders as having a sense of humour report being more satisfied, more creative, and performing at a higher level.

None of that requires anyone to become a comedian. It requires a team that has stopped treating the humour cliff as an inevitable, sensible part of adulthood, and started treating it as exactly what it is: a cost, quietly paid by almost every organisation, that few ever bothered to add up.

The Levity Works is built around exactly these ideas, and more, for leadership teams, HR directors and anyone who wants a genuinely warmer, more connected working culture without the forced fun or the cringe of team building done badly.

The skills come from comedy. The application is entirely serious.

If the room itself is warm but the material your team brings into it is not yet strong enough, Developing Stronger Ideas picks up that earlier, separate problem.

Comedy without jokes, in the same way this workshop is comedy without performance.

If the room you are trying to win is a client room rather than your own team, what a pitcher has in common with a stand-up comedian picks up that side of the same overlap.

People also ask

What is the humour cliff?
The humour cliff is a term coined by Stanford researchers Jennifer Aaker and Naomi Bagdonas to describe the sharp decline in how often adults laugh compared to children. A four-year-old laughs roughly 300 times a day. An adult around forty takes closer to two and a half months to laugh that many times. The decline begins sharply around age twenty-three, coinciding with people becoming serious about their careers.

Does humour actually improve workplace performance?
Research supports this consistently. A meta-analysis of 49 studies involving more than 8,500 participants found that positive humour strengthens both individual resilience and group cohesion. Leaders who use humour effectively are seen as more motivating and approachable, and employees who see their leaders as having a sense of humour report higher satisfaction, creativity and performance.

What is the difference between appropriate and inappropriate workplace humour?
Appropriate workplace humour draws on shared, common experience, the universally recognised frustrations and absurdities of working life. It never singles out an individual. The moment humour targets a specific person, even gently, it stops building trust and starts eroding it. The safest and most reliable territory is low-key and shared rather than sharp or personal.

Can workplace levity actually be taught, or is it a personality trait?
It is a learnable skill rather than a fixed trait. It involves specific behaviours such as how a meeting opens, how a team responds when something goes wrong, and recognising the difference between humour that includes everyone and humour that singles someone out. Comedians develop this through repeated practice reading rooms, and the same judgement transfers directly to a workplace context.
