Group Dynamics and Leadership: The Role of Informal Leaders

Rotterdam – The wind cuts across the Maas, pushing against steel, glass, and skin. Containers move like clockwork in the port, every shift calculated, every delay costing money, safety, and trust. Somewhere inside a team room in healthcare, far from the cranes but tied to the same rhythm, a decision is made. Not written in policy first, but felt in the room. Who speaks, who follows, who sets the tone. That is where leadership lives today.

Not only in job descriptions. Not only in contracts signed from above. But in behavior. In influence. In the quiet agreements people make without ever writing them down. This is where the Leary Circle, developed by Timothy Leary, becomes more than theory. It becomes a way to see what is already happening.

From hierarchy to influence: the shift no one can ignore

There was a time when leadership was clear. A team leader stood at the top. Instructions went down. Work went up. It was structured, predictable, and in many environments, effective. Especially when work was repetitive and teams were built on similar backgrounds and expectations. But the world shifted. Healthcare teams today are not built on sameness. They are multicultural, layered with experience, shaped by different values, languages, and expectations. The role of the formal leader—once dominant—has changed. Not disappeared, but transformed.

Today’s formal leader still carries responsibility. For outcomes, for safety, for budgets, for accountability toward organizations and systems. That responsibility has not become lighter. If anything, it has become heavier. But control alone no longer delivers results. Because influence does not follow hierarchy automatically anymore. And that is where informal leadership enters the picture.

The informal leader: not assigned, but emerging

The informal leader is not appointed. There is no contract, no title, no official role. Yet the presence is undeniable. In every group, someone—or sometimes several people—becomes the reference point. Others look at them before reacting. Their tone becomes the tone of the room. Their approval or resistance carries weight. This does not happen through meetings or votes.

It happens through interaction. Through trust. Through shared experience. Through the feeling of “this person represents us.” The informal leader is not chosen in words, but in behavior. And this position is built on something stronger than formal authority: unwritten rules.

These rules define:

• how people speak to each other
• what is acceptable and what is not
• when to push and when to hold back
• who gets space and who gets silence

No document explains them. Yet everyone feels them. That is real power.

The Leary Circle: behavior creates behavior

The strength of the Leary Circle is not in labeling people, but in exposing patterns. Two axes: dominant versus submissive, cooperative versus opposing. Simple in structure, complex in reality. Behavior creates behavior. A dominant move invites submission or resistance. A cooperative move invites cooperation. A confrontational tone brings tension into the room. This is not abstract psychology. This is daily reality in teams.

In healthcare, that reality has consequences. A tense team creates tension in care delivery. Miscommunication leads to errors. Resistance slows processes. Cooperation, on the other hand, builds safety, clarity, and flow. The model shows where behavior sits. Not who a person is, but what they are doing in that moment. And because behavior shifts, so does influence.

Formal and informal leadership: not opposition, but interaction

There is a tendency to think in opposites. Formal versus informal. Control versus freedom. Structure versus autonomy. But in real teams, especially in environments like healthcare, it is not a battle. It is a dynamic relationship. The formal leader sets direction. Without direction, there is fragmentation. In sectors where safety is critical, that fragmentation is not a minor issue. It affects real lives. The informal leader builds alignment. Without alignment, direction stays on paper. Policies exist, but behavior does not follow. This is where many systems struggle.

Formal leaders push for outcomes. Informal leaders shape the response. If they are not aligned, tension grows. Resistance becomes subtle but powerful. Plans slow down or quietly fail. If they align, movement happens. Direction becomes action. The key is not control, but recognition.

Influence is not fixed: it moves with the situation

One of the most important insights is this: the informal leader is not a permanent role. It shifts.

In a crisis, someone with calm authority might take the lead. In a technical discussion, the most knowledgeable voice becomes central. In emotional moments, the most trusted person shapes the response. The group does not follow one person all the time. The group follows what feels right in the moment. That makes leadership fluid. It also makes it harder to manage if leadership is only understood as a position instead of a process.

Healthcare reality: where behavior meets consequence

In healthcare teams, these dynamics are not theoretical. They show up in outcomes.

A misaligned team leads to:

• increased workload
• communication breakdowns
• safety risks
• reduced quality of care

These are not soft consequences. They affect budgets, staffing, and trust. Errors cost money. Staff burnout leads to absence. Inefficiency drains resources. In a system already under pressure—from rising energy costs to staffing shortages—these factors matter.

Leadership is not only about people. It is about economics. About sustainability. About keeping systems functioning. That is why understanding informal influence is not optional. It is operational.

Rotterdam underneath it all: rhythm, fairness, and shared ground

Underneath this analysis, there is a layer that cannot be ignored. A rhythm shaped by places like Rotterdam. The port teaches something simple: nothing moves alone. Every process depends on connection. If one link fails, the system feels it. There is no room for illusion about independence. Everything is connected. That same reality exists in teams. Multicultural environments bring strength, but also complexity. Different ways of speaking, different expectations, different interpretations of authority. Without awareness, that leads to friction. With awareness, it becomes power.

There is also a strong sense of fairness. A directness. A shared understanding that respect is earned in behavior, not in titles. That is where informal leadership thrives. Not in systems, but in people.

Power and powerlessness: the thin line

The difference between power and powerlessness in a team is often not visible in structure. It is visible in interaction. A formal leader who ignores informal influence can lose real control, even while holding the official position. Decisions are made, but not followed. Instructions are given, but not carried out with commitment. That is powerlessness in disguise.

An informal leader without direction can pull a team into chaos. Energy without structure leads to confusion. Movement without clarity leads to mistakes. That is uncontrolled power. The balance lies in interaction. Formal leadership provides structure. Informal leadership provides movement. Together, they create function.

Seeing the room: the real skill

The essential skill is not authority. It is awareness. Who speaks and is followed? Who shapes the mood? Where does resistance sit? Where is cooperation natural?

These are not questions answered in reports. They are answered in observation. In meetings, in conversations, in silence. The Leary Circle provides a lens. It does not give answers, but it sharpens perception. And perception is what allows leadership to move from control to influence.

Conclusion: leadership as a living system

Leadership today is not static. It is not fixed in roles or titles. It is a living system. Formal leaders create conditions. Informal leaders activate people. Behavior connects the two. In environments like healthcare, where stakes are high and resources are under pressure, this system determines outcomes. Not just in performance, but in wellbeing, safety, and sustainability.

Understanding this is not theoretical knowledge. It is practical awareness. And in places shaped by movement, diversity, and resilience—like the city along the Maas—it becomes something else entirely. It becomes survival.
