"Can complexity be managed, or can it only be led from within?"

That question opened a GMA community gathering this May, and it splits the world of leadership development in two. Most programs have a confident answer to the first half. They teach complexity management: frameworks, stakeholder maps, strategic planning, change models. The second half of the question is where cities actually live.

THE FEELING THAT SOMETHING STAYED OPEN

Many city leaders carry an MBA, a public administration degree, or a shelf of leadership certificates. The knowledge is real and it serves them daily. And still, a lot of them describe the same quiet residue: under real pressure, in the council chamber or the community hall, something in them runs on older software than the frameworks they studied.

Dr. Paddy Pampallis, writing to city leaders in May 2026, named the structure of that residue precisely: "Design and implementation and procedures and policies are abundant. But executing on them always gets stuck by the inability to access this operating system."

And the companion sentence: "We have never truly learnt how to access our human Operating System well."

Plans are abundant. Policies are abundant. The scarce resource is inner access: the capacity to stay clear, present, and decisive while ten urgent files and forty stakeholders pull in different directions. Classic programs certify knowledge. Cities demand maturity. Those are two different curricula.

MATURITY IS A MEASURABLE THING

"Maturity" here is a precise term from adult development research. Drawing on Susanne Cook-Greuter's framework, Paddy Pampallis describes three broad stages a leader can grow through: the socialised mind, the self-authoring mind, and the self-transforming mind.

Each stage describes how much complexity a person can hold while staying functional. A socialised mind leads by the expectations of its environment. A self-authoring mind leads from its own framework. A self-transforming mind can hold several frameworks at once, including the ones that contradict each other, which is the everyday texture of running a city.

In Paddy's words: "Not because the earlier stages are wrong, but because what we hold now requires a complexity of attention that has to be grown, not assumed."

Two properties make this practical for a working mayor: maturity can be measured, and maturity can be developed. It moves the conversation from personality ("some leaders just have it") to capacity ("this can be trained").

THE GAP WITH A NAME

There is a name for the distance between a leader's stated principles and their behaviour under pressure: the reflective-enacted gap, the measurable difference between what a leader says they will do and what they actually do when the heat is on.

Knowledge-based programs close the reflective side: a graduate can articulate excellent principles. The enacted side closes through a different mechanism: lived experience of consequences, practice in real or realistically simulated decision fields, feedback on what you actually did. This is why a leader can score brilliantly on a strategy exam and still watch their espoused values evaporate in a budget fight. The exam tested one curriculum; the budget fight ran the other.

WHY THIS MATTERS FOR HOW DEVELOPMENT IS DESIGNED

Here is a detail that reframes the economics of it all. In conversations with city leaders, one fact comes up again and again: for a mayor, GBP 6,000 is findable. Five to six hours per week for seven months is the real challenge. (from a GMA working call, May 2026)

Time, the carrier of attention, is the scarcest resource a city leader has. So a development architecture for mayors has to answer a hard design question: how does every hour spent close the enacted side of the gap, with peers who carry the same weight?

That question is the foundation the Global Mayors Academy program is built on: leadership maturity as the core curriculum, practiced with mayors and city leaders from every continent. If the residue described above feels familiar, the question that opened this post is worth sitting with, and we would be glad to sit with it together.
