Leadership and Culture Change: Modeling Is the Lever Everything Else Depends On

By Joe Newsum

Every organization already has a culture, and it was built almost entirely by what its leaders model. Not what they say in town halls or write in values statements. What they do in the room, what they reward, what they let slide. Most leaders have never thought of themselves as the primary authors of their culture, but they are, and they are writing it whether they intend to or not.

This is the uncomfortable truth at the center of leadership and culture change. You cannot opt out of modeling. The only choice is whether you do it consciously, toward the culture you actually want, or unconsciously, defaulting to whatever behaviors come naturally and calling the result an accident.

If you are running a deliberate culture change effort, with commitments designed and a plan in place, this is the lever that determines whether any of it works. It is not the quality of your commitments, though that matters. It is not the launch event, though that matters too. It is whether your leadership team models the standard, visibly, consistently, and without exception. Leadership modeling is not one lever among many. It is the lever every other lever depends on.

Why Modeling Is the Master Lever

To understand why modeling sits above every other lever, you have to understand how people actually learn, not how organizations assume they learn. Most culture programs are built on the assumption that people learn through information: explain the values, train on the behaviors, launch with a good presentation, and adoption follows. That is not how human beings work.

Ninety percent of how people learn to operate in an organization comes from watching what happens around them and drawing conclusions from it. And within that ninety percent, leaders are the most watched people in the building. People are not doing this consciously. They are doing it the way humans have always learned from the people above them in any social structure, through mimicry.

Mimicry is not a weakness or a shortcut. It is the primary mechanism through which human beings absorb norms and ways of operating. And it does not weight every example equally. Human beings are wired to copy high-status individuals far more than their peers, a tendency cognitive scientists call prestige bias. We evolved in groups where imitating whoever the community held in highest regard was a reliable shortcut to learning what worked, and that wiring did not switch off when we put on suits and built org charts. A single behavior modeled by a senior leader carries more cultural weight than the same behavior modeled by a hundred individual contributors. Leaders do not just happen to be watched. They are the examples human instinct is built to copy first.

This is why modeling is the lever every other lever depends on. You can communicate the culture, train people on it, build accountability around it, recognize it, and tie incentives to it, but if leaders do not visibly live it, every one of those other levers loses its credibility at once. People do not need to be told the culture is not real. They can see it.

The practical question, then, is what leaders are actually modeling. In the moment, day to day, it comes down to four things people are always watching: what you say, what you do, what you reinforce, and what you tolerate. Get these four right, consistently, and you are modeling the culture. Get any of them wrong and you are modeling something else, whether you mean to or not.

What You Say: The Language You Use in Real Moments

The conventional advice is that leaders should model the behaviors they want to see. True, but incomplete, and the incompleteness is why so much of it fails to produce anything. Behavior is hard to copy. It is situational, personal, and often invisible until the situation that calls for it arrives. If modeling were only about behavior, it would transmit slowly and inconsistently, because most people never see most of what a leader does.

What actually transmits at scale is language. When a leader names a standard out loud, in a real moment, they hand every person in the room a portable piece of the culture they can carry into rooms the leader will never enter. The words travel where the behavior cannot. This is the mechanism underneath the whole methodology: language shapes thinking, thinking shapes behavior, and consistent behavior is what culture is. A behavior modeled once reaches the people who happened to be present. A phrase modeled once can be repeated by everyone who heard it, indefinitely.

The test is specific and unforgiving. Are you using the cultural language in real interactions, or only in presentations and at launch events? In actual meetings, in actual feedback conversations, in actual decisions? A leader who believes in collaboration but never names what collaboration looks like, in language people can repeat, has given the organization nothing to transmit. A leader who says “we disagree in the room and commit outside it” has handed every person a sentence that does the cultural work on its own, in meetings that leader will never attend. If the language is not showing up where the real work happens, it is not yet modeled.

Think about the cultural standards you most want people to live. Have you given them language they can actually repeat? Or are you asking them to copy a behavior they have never clearly heard you name?

What You Do: The Say-Do Gap Teaches Faster Than Either Alone

If language is the most powerful thing a leader can model, the gap between language and behavior is the most powerful thing a leader can model by accident. When what you say and what you do point in different directions, people do not split the difference. They conclude the words were never serious, and they learn that lesson faster than they would have learned either the words or the behavior on its own. A say-do gap does not teach nothing. It actively teaches that the culture is theater.

This is why behavior is not optional once you have used the language. Naming a standard raises the stakes on living it. If the standard is about how meetings are run, run your meetings that way, every time, starting with your own team. If it is about feedback, give feedback that way. The test is concrete: if your own direct reports cannot point to specific ways you operate differently than you used to, you are not yet modeling, no matter how often you talk about the culture. Your team sees you in the unguarded moments, under pressure, when the old way is easier, and what they watch you do becomes their permission structure for what they do.

What You Reinforce: Rewards Reveal the Culture You Actually Have

There is what an organization says it values, and there is what it rewards. When the two diverge, people believe the rewards, every time. This is the quiet reason values statements fail: an organization can claim collaboration while promoting its most territorial performers, and everyone watching learns the real lesson within a quarter. What gets recognized and rewarded is the truest statement a leadership team makes about its culture, because it is the one backed by consequences.

That makes reinforcement a lever, not a nicety. Recognition from a senior leader does two things at once: it tells the person they did something that matters, and it tells everyone watching what great looks like here. The test is whether it is actually happening. If the people around you cannot recall a recent, specific moment when you called out someone living the culture well, this lever is sitting idle, and the organization is reading your silence as a signal that living the culture does not actually change anything.

What You Tolerate: The Standard You Actually Hold

This is the pillar leaders underestimate most, and the one that does the most damage when it goes wrong. What you allow to pass without comment is what the organization concludes is acceptable, regardless of anything you have said. Tolerating a violation is modeling too, just in the wrong direction. Silence is never neutral. It is a verdict.

People are exquisitely tuned detectors of whether leaders mean what they say. This is not a phenomenon specific to certain organizations. It is a human survival instinct. When a leader names a standard and then visibly lets it slide in the next meeting, the organization does not say anything. It simply files the observation away: another initiative, not a real change. And that cynicism spreads faster than commitment, because a single tolerated violation is visible to everyone present, and every one of them draws the same conclusion and passes it on.

The most dangerous version of this is what I call the exemption signal. When one leader visibly exempts themselves from a standard everyone else is holding, the organization does not conclude that one leader is struggling. It concludes that the standard is negotiable for anyone with enough seniority or enough excuse. The single exemption carries more information than all the compliance around it, because it answers the only question people are actually asking: is this real, or can I opt out?

This is why the math of modeling is brutal and counterintuitive. It is not additive, where each leader who holds the line adds a little progress. It is closer to multiplicative, where a single leader who openly opts out divides the whole effort back toward zero. Nine leaders holding the standard and one exempting does not net out to ninety percent. The organization fixates on the exemption, because the exemption is the tell.

Are You In, or Are You Actually In?

The four pillars describe what modeling looks like. The harder question is what it takes to genuinely commit to it, because saying you will model the culture and actually changing how you operate are two very different things. In my work with executive teams, I have found that the most important and most underestimated moment in any culture change effort is the one where leaders are asked to truly commit to personal modeling, not just endorse the program.

At a Fortune 500 company where I was leading a culture change effort built around meeting standards, I spent time with each member of the executive team individually before the first workshop. We worked through the standards together, which meant each leader had genuine ownership of the language by the time we convened. The workshop itself covered the standards in depth. But it was the last fifteen minutes that mattered most, when the CEO stepped in to drive his point home.

What the CEO did with those fifteen minutes is the most replicable insight on this page. Most leadership sessions extract commitment socially. The leader makes the case, looks around the room, and people nod, because nodding is what you do when your peers and your boss are watching. That nod is worthless. It is a performance of agreement, not a decision to change. Real commitment to modeling cannot be extracted in a room. It has to be decided alone.

By sending them away for a week, he inverted the normal dynamic. He made the commitment private before he made it public. Each leader had to sit, by themselves, with the actual cost of changing how they personally operate in front of their own teams, for years, under pressure, when the old way still felt easier. The ones who came back and said they were in had made a real decision, not a social one.

If you asked every member of your leadership team today whether they were modeling the culture they say they want to build, what would they say? More importantly, what would the people who work for them say?

The Leadership Modeling Audit

Use this as a one-page diagnostic. Run it on yourself first, in private, with the real cost in view, the way the executives in the story had to. Then run it on your leadership team together. Four questions, answered honestly. The gaps you find are not failures. They are the roadmap, and the order in which to close them.

Culture change does not require perfection. It requires honesty about where the modeling is falling short, and the discipline to close the gap before the organization decides the gap is the real culture. You are modeling something right now, in every meeting, every decision, every thing you let slide. The only question that has ever mattered is whether you chose it.
