You know the smile. It goes on somewhere between the back door and the first customer, and it stays on for the whole shift. By the end of it your cheeks ache, your patience is gone, and you cannot quite explain why a day spent being pleasant left you feeling so unpleasant.
For years the advice ran the other way. Fake it till you make it. Put on a happy face and the happy feeling will catch up. There was even research behind it.
Now there is research behind the other half of it. Forcing a smile, it turns out, has a hard limit — and the scientist who found that limit is the same one who helped prove the original idea.
What the New Study Found About Forcing a Smile
Researchers at the University of Florida ran an online experiment with 1,201 people and analysed the results from 1,174 of them. The paper — by Nicholas Coles, Annabel Dang and Joao Francisco Goes Braga Takayanagi — was published in the Journal of Experimental Social Psychology as a registered report, which means the design and the analysis plan were reviewed and locked in before any data was collected. Nobody could go looking for a result afterwards and call it a prediction.
The setup was simple. Participants looked at pictures. Some were pleasant — kittens, flowers. Some were unpleasant — theft, animal mistreatment. They were asked either to pose a smile or to let their face do whatever it wanted to do. And here is the detail that turned out to matter most: some did it once, and some did it ten times.
Then the researchers added pressure. Half of the participants were told they could lose $2 of their $6 payment if they were not smiling properly. In the end nobody lost a cent — but they did not know that while they were smiling.
Three things came out of it.
- One smile, no pressure, looking at something unpleasant: a small lift in mood. The old advice held up.
- Ten smiles: the lift shrank. Add the threat of losing the money and it vanished altogether.
- Repeated or pressured smiling at the pleasant pictures: people ended up less happy than the people who had simply let their faces react naturally. A further analysis found those forced smiles also tended to raise irritation and anger.
Read that last one again, because that is the finding. The people being paid to look happy at nice things felt worse than the people who were just allowed to look at nice things.
The Scientist Who Proved the Opposite First
This is the part that makes the study worth more than a headline. Nicholas Coles is not an outsider taking a swing at the “smile and you’ll feel better” idea. He is one of the people who established it.
In 2022 Coles led the Many Smiles Collaboration, a multi-lab project that gathered data from 3,878 participants across 19 countries and deliberately recruited researchers from both sides of the argument. It was published in Nature Human Behaviour, and it found that posed smiles really can raise happiness a little.
A little. Coles was careful about the size of it at the time: roughly the same lift you get from looking at mildly pleasant photos of rainbows and puppies, and nowhere near strong enough to shift something like depression. That caveat did not travel. The headline did. “Forcing a smile might put you in a better mood” went out through newsrooms around the world, and the version most people kept was a lot more confident than the version the researchers published.
So the new experiment is really the same scientist asking the obvious follow-up question. What happens when the smile is not a one-off in a lab, but a condition of being paid? Coles has reason to wonder. He has said that he was written up at a job once — at an unnamed theme park in Florida — for his inability to keep smiling at work.
A Required Smile Is Not the Same Thing as a Smile
The variable in this study was never really the shape of the mouth. It was who the smile belonged to.
A smile you choose is an expression. A smile you owe somebody is a task — and a task you can fail. The moment a $2 penalty entered the room, a facial movement that had been mildly helpful turned into one more thing to be graded on, performed while already tired, in front of someone with the power to decide you had not done it well enough.
That describes a great many jobs. The researchers pointed at a real example: the American retailer Target drew heavy criticism for a customer-service policy telling staff to smile and make eye contact with any shopper who came within about ten feet — roughly three metres — and to greet them personally inside four feet. The intention was friendliness. The thing it quietly created was a quota.
And it is not only work. It is the family dinner where everyone has agreed to pretend. It is the group chat where “I’m fine” is the only acceptable answer. It is the wedding, the church hall, the ward visit, the video call with relatives who would worry. The study used a $2 threat because that was measurable. Most of the pressure people actually live under is not measurable at all, and it does not expire at the end of a shift.
Which may be why the irritation result rings so true. Norman Farb, a psychologist at the University of Toronto Mississauga who was not involved in the research, suggested the effect might be simpler than it looks — forced smiling may just create an “annoyance effect.” Being made to perform a feeling you do not have is annoying. That is not a complicated mechanism. It is just one nobody bothered to measure.
Farb also named the honest limit of the work, and it is worth keeping: whether years of required cheerfulness do real damage to wellbeing is plausible, but, as he put it, “this study cannot speak to that claim.” This was an online experiment with a simulated penalty, run over minutes, not a study of a career. It tells you what a forced smile does in the moment. It does not tell you what twenty years of them does.
What to Do With a Smile You Did Not Choose
Nobody is going to quit a job over a facial expression, and the study does not ask anyone to. What it does is take away the obligation to believe the smile is working.
That matters more than it sounds. The cruelty of “just stay positive” is not only that it does not help — it is that when it does not help, you assume the failure is yours. You were given a technique, you applied it, and you still feel terrible, so the problem must be you. This research says: no. In the conditions you are actually living in — repeated, required, watched — the technique itself stops working, and for some people it runs backwards. That is the equipment, not the operator.
What is strange is how old that permission is. Long before anyone ran an experiment, the people whose whole job was writing wisdom down had already noticed that laughter can sit right on top of a sorrowful heart. They wrote it as an observation, not a problem to be solved. Nothing in that tradition asks a person to look happier than they are; it takes for granted that God can be approached by someone who is not doing well, without first arranging their face. That is a surprisingly modern piece of relief to find in a very old book — and it is more or less the same thing we have written about the quiet pressure to perform okay-ness before.
If any of this is landing a bit too accurately, it may be worth finding out how much you are actually carrying. Our free Am I Burned Out at Work? assessment takes a couple of minutes and gives you a straight answer rather than a slogan. And if you have ever wondered whether cheering someone up helps or hurts, the timing turns out to be nearly everything — which is what a separate review found about whether laughter helps depression.
Five Things Worth Trying
All of these are free, and none of them need a therapist, a day off, or anybody’s permission.
- Learn the difference between a smile that arrives and a smile you install. You already know it in your face. Once you can feel which one is happening, you stop confusing one for the other.
- Stop grading yourself on the installed one. Do it because the job needs it. Do not also expect it to fix your mood, and do not take it as a personal failure when it doesn’t.
- Take the mask off somewhere, every day. One person, five minutes, one honest sentence. Not a confession — just not a performance.
- Do not start a second shift at home. If you spent eight hours being pleasant on request, walking in the door and immediately performing again is the ten-repetition condition. Ask for ten quiet minutes first.
- Let a good thing just be good. The oddest result in the whole study is that performing happiness at something genuinely nice made people less happy than quietly enjoying it. When something lovely happens, you are allowed to simply have it. No face required.
What Do You Think?
Here is the question this study leaves open. Should any employer be allowed to require a smile as part of the job — the way they can require a uniform or a safety helmet — or is a facial expression one thing that has to stay the worker’s own? There are decent arguments both ways, and the answer probably depends on the job. Tell us where you land in the comments.

Questions People Ask About Forcing a Smile
Does forcing a smile actually make you happier?
Sometimes, slightly, and only under narrow conditions. A 2026 University of Florida experiment published in the Journal of Experimental Social Psychology, with 1,174 participants analysed, found that posing a single smile while looking at something unpleasant produced a small mood lift. But smiling ten times in a row shrank that benefit, and adding a financial penalty for not smiling properly erased it. When people repeatedly or pressure-smiled at pleasant images, they reported being less happy than people who let their faces respond naturally.
Why does forcing a smile at work feel worse than smiling at home?
Because of repetition and consequence, which are exactly the two things the University of Florida study added to the classic experiment. A smile you choose once is an expression; a smile required of you many times a day, with a penalty attached for doing it badly, becomes a task you can fail at while already tired. In that condition the researchers found the mood benefit disappeared, and in the pleasant-image conditions forced smiling tended to raise irritation and anger instead.
Is the “fake it till you make it” advice wrong?
It is not wrong so much as oversold. The same researcher who led the 2026 study, Nicholas Coles, also led the 2022 Many Smiles Collaboration — 3,878 participants across 19 countries, published in Nature Human Behaviour — which did find that posed smiles can raise happiness. Coles described that effect as very small, comparable to looking at mildly pleasant photos, and said it was not strong enough to overcome a condition like depression. The advice was built on a real but modest finding, then repeated as if it were a cure.
Can forcing a smile make you angry?
The 2026 University of Florida study found that it can. In an additional analysis of the pleasant-image conditions, forced smiles tended to increase irritation and anger alongside reducing happiness. Norman Farb, a University of Toronto Mississauga psychologist who was not involved in the research, suggested this may be a straightforward “annoyance effect” — being required to perform a feeling you do not have is simply irritating.
What are the limits of this study?
Three worth knowing. It was an online experiment, not a study of real workplaces. The financial pressure was simulated — participants were told they could lose $2 of a $6 payment, but nobody actually lost money. And it measured minutes, not years: Farb noted that whether long-term required cheerfulness causes real wellbeing costs is plausible but, in his words, “this study cannot speak to that claim.”
