“Have fun and be yourself” is the kind of line that shows up in onboarding decks and culture pages, usually paired with a photo of people laughing around a whiteboard. It carries two separate claims folded into one piece of advice: that enjoying the work matters, and that not adapting yourself to fit the room is the better way to move through it. The research on each half points in noticeably different directions.
The part of “being yourself” the research does not support
The psychologist Mark Snyder built a body of research around what he called self-monitoring, a personality dimension describing how closely a person adjusts their behaviour to fit the social situation in front of them, as opposed to acting consistently from their own internal attitudes regardless of context. A high self-monitor reads the room and adapts. A low self-monitor behaves the same way whatever the room is, which is closer to what “just be yourself” actually recommends.
In a 2002 meta-analysis in the Journal of Applied Psychology, the researchers David Day, Deidra Schleicher, Amy Unckless, and Nathan Hiller pooled 136 samples covering more than 23,000 people and found self-monitoring correlated positively with job performance, with the relationship strongest for supervisor ratings and for leadership emergence and roles that require moving between different groups. The correlation was modest, in the region of 0.09 to 0.15 depending on how performance was measured, not a large effect. But the direction runs against the advice. This is one meta-analysis, not the final word on every job, and a modest correlation is not a guarantee for any individual. Still, on this evidence, adapting to the room, not simply behaving the same way in every room, is the pattern associated with better outcomes at work.
Why authenticity still shows up as genuinely good for something else
None of this makes “be yourself” bad advice for the reason people usually give for it, which is rarely about performance ratings. In a 2011 study in the Journal of Managerial Psychology, the researchers Josée Ménard and Luc Brunet surveyed 360 public-sector managers in French-speaking Canada and found that people who reported feeling more authentic at work also reported higher job satisfaction and more positive affect, with the relationship running partly through a sense that the work felt meaningful. This is one study, with one specific working population, not a claim that authenticity guarantees satisfaction for everyone in every job. But it points to a genuine benefit, just not the one “have fun and be yourself” is usually invoked to deliver. Authenticity in this research tracks with feeling better at work. It does not, on the self-monitoring evidence, track with being rated as more effective by the people evaluating that work.
What happens when the two goals actually compete
A separate line of research asks what people who present themselves strategically, rather than consistently, actually gain. A systematic review pooling multiple studies on impression management and career outcomes found that tactics like self-promotion and ingratiation, both of which involve adjusting self-presentation to the audience rather than simply expressing oneself the same way regardless of context, were consistently linked to better salary outcomes, promotion rates, and supervisor ratings. A separate meta-analysis focused specifically on interviews found the same pattern for interview and job performance ratings. Neither of these is a single small study. Both describe a genuine, moderately sized advantage for strategic self-presentation over unfiltered consistency, the opposite instinct to “just be yourself.”
Researchers who study this space, including Herminia Ibarra, Laura Morgan Roberts, and colleagues writing on what they call the authenticity paradox, have argued that full, unfiltered self-disclosure at work can actively undermine how competent and credible a person appears, particularly earlier in a role before trust has been established. Their argument is not that people should perform a false version of themselves indefinitely. It is that the useful version of authenticity in a professional setting tends to be selective and adapted over time, closer to self-monitoring than to raw consistency.
The half of the advice about having fun is more conditional than it sounds
The “have fun” half fares somewhat better in the research, with an important qualifier. A meta-analysis in the Journal of Managerial Psychology by Jessica Mesmer-Magnus, Denise Glew, and Chockalingam Viswesvaran found humour in the workplace correlated with both job performance and better coping with workplace stress, corrected correlations in the range of 0.29 to 0.36, a meaningfully larger effect than the self-monitoring result. This is a genuine, moderately sized pooled finding, not one small study, and it gives real support to the idea that enjoying the work in some form is associated with doing it better.
The qualifier concerns what kind of fun. Research building on the psychologist Rod Martin’s Humor Styles Questionnaire distinguishes affiliative and self-enhancing humour, jokes that bring people together or help someone cope without costing anyone else anything, from aggressive and self-defeating humour, jokes made at someone else’s expense or one’s own. A 2023 study of 462 Italian workers found the aggressive and self-defeating styles specifically linked to poorer emotion regulation, while the affiliative style showed no such association. A separate study of 452 employees across 140 teams found a leader’s affiliative humour predicted more of a specific helpful behaviour among team members, employees speaking up and acting on things outside their formal role. “Have fun” does real work in this research. It is not a blanket licence for any kind of humour a person prefers, and the type matters more than the instruction usually acknowledges.
What this leaves standing
Put together, the research supports a narrower and more specific version of the advice than the slogan implies. Enjoying the work, in an affiliative rather than an aggressive or self-defeating form, is genuinely associated with better performance and better coping, on evidence from a real pooled sample rather than a single small study. Feeling authentic at work is genuinely associated with satisfaction and a sense of meaning, on the evidence from at least one solid working sample. But the specific instinct behind “be yourself,” meaning behaving consistently regardless of the room rather than reading and adapting to it, is the part the self-monitoring and impression-management research complicates most directly. Adapting to the situation, not resisting it, is the pattern that shows up linked to how a person is actually rated and rewarded.
None of this settles what any one person should do in any one meeting, and the studies gathered here were never designed to test each other head to head. What they suggest, taken together, is that the advice works better split in two than left as one line on a slide: have fun, in the specific sense the humour research supports, and adapt more than the phrase “be yourself” usually implies you should.
