From the heroic individuals to fusion institutions: Why academia must learn to think in four dimensions

Last week, in a boardroom at a leading business school, a group of alumni, faculty and staff gathered to talk about sustainability.

On the surface, it looked familiar. Net zero targets. Emissions baselines. Rankings. The usual pillars of a modern institutional strategy.

But underneath, something more interesting was happening. The conversation kept breaking out of its old container.

Instead of asking “How do we strengthen our sustainability offering?”, people were asking:

What kind of capitalism are we teaching?

How do we prepare leaders for AI, climate instability, resource stress and political turbulence at the same time?

What does it mean for a business school to act responsibly in a world where the system itself is in question?

In other words, the board meeting had become a live recognition that the problems we face go far beyond one campus.

We are trying to navigate the twenty-first century with a mental model that belongs to the twentieth.

We are still hoping that one more framework, one more course, one more specialist will be enough to tame a world that no longer exists.

The megasystem problem

In a previous piece, I argued that we are dealing with a failure of dimensionality. Climate change, biodiversity loss, water stress, AI disruption, democratic erosion, supply chain fragility, forced migration and financial instability are no longer separate “issues”. They are expressions of the same underlying system, across space and over time.

We built entire institutions, including universities and business schools, on the assumption that expertise could be divided, bounded and arranged in departments. Economics here. Technology there. Politics somewhere else. Ethics in a short module on a Friday afternoon.

That world is gone.

Today’s crises refuse to stay in their lanes. Feedback loops overlap. Local shocks travel instantly through global systems. Solutions in one domain quietly create new risks in another. Ethical questions mutate as circumstances change.

Systems thinking helped us take a step forward. It taught us to look for patterns rather than events, to map feedback loops, to escape simple cause and effect. But even systems thinking begins with a choice: what counts as “inside” the system.

And right now, every boundary we draw around a problem is provisional. The system keeps leaking.

The fusion team, not the heroic individual

The twentieth century liked the story of the singular genius. The gifted economist. The visionary technologist. The brilliant CEO. We still cling to this narrative in how we design biographies, rankings and leadership programmes.

Meaningful solutions now sit beyond the reach of any single discipline or leader. No one person can hold all the necessary dimensions in their head at once.

If one mind cannot hold the whole, the unit of change has to be the team.

Not a team in the old sense of a group of specialists who each defend their patch, but what I am thinking of as a fusion team:

• Able to hold multiple viewpoints at the same time
• Treating challenges as timelines rather than snapshots
• Tracing causes across space and duration
• Willing to revise shared understanding as reality moves

This is not collaboration as a box-ticking exercise. It is continuous reconstruction. Shared mental models with an expiry date.

What surfaced in that board meeting was the realisation that we need fusion teams. And that business schools themselves must learn to become fusion institutions if they want to stay relevant.

Business schools at the edge of their own map

The alumni in the room were not just asking for more sustainability electives. They were asking for something closer to “responsible capitalism” or “business for good”.

They wanted AI ethics in the same conversation as climate risk and externality pricing. They wanted biodiversity and water stress considered alongside supply chains and emerging market debt. They wanted the lived reality of the global South in the same frame as European energy markets and US industrial policy.

They were, in other words, asking the School to stop pretending that “sustainability” is a discrete topic that can be bolted on to a 1990s MBA.

They were asking it to think in four dimensions.

Three lessons emerged:

First, the old mental model of incremental sustainability is not enough. You can have a serious Scope 1 and 2 pathway, a glossy report and a set of green campus initiatives and still fail to prepare students for the world they are walking into.

Second, the speed mismatch between academia and reality is now dangerous. Curriculum cycles still assume a world where you can design a course, get it through committees, run it for a few years and then tweak. AI, climate shocks and geopolitical shifts do not respect that tempo.

Third, structure matters. As long as sustainability sits in a corner, as a unit or a theme, it will compete with “core” priorities rather than redefining what counts as core.

If business schools want to help build fusion teams, they cannot rely on heroic individuals. They have to change their own architecture.

What a fusion institution looks like

So what might that look like in practice?

Start with the organising idea. Moving from “sustainability” to “responsible capitalism” or “business for good” is not about branding. It is about admitting that the real curriculum is now:

How do we keep capitalism inside planetary and social boundaries without tearing societies apart?

Once you start from that question, several academic habits become untenable.

You cannot teach finance as if externalities are footnotes. You cannot teach strategy as if climate, AI and political risk are exogenous shocks. You cannot teach technology as if energy, labour and dignity are someone else’s problem.

A fusion institution does three things differently.

First, it builds around grand challenges, not departmental lines. Imagine cross-cutting pillars such as:

• AI for good and for governance
• Climate and nature risk
• Responsible finance and externality pricing
• Global resource stewardship
• Development, equity and the global South

These are not new silos. They are scaffolding. They give students, staff and faculty permission to think across programmes and timeframes.

Second, it treats curriculum and research as living systems.

The default assumption becomes that any course, case or framework may need revision faster than before. Feedback from practice is not a nice-to-have, it is central. Alumni on the frontlines of energy transitions, AI deployment or food systems become partners in ongoing course design, not occasional guest speakers.

Third, it trains people to work with expiry dates on their understanding.

This is perhaps the hardest cultural shift. It asks faculty to admit uncertainty in public. It asks students to become comfortable operating without closure. It asks leadership to accept that a “finished” solution is an illusion.

The role of academia is not to provide final answers. It is to cultivate the capacity to update.

Why this matters beyond one school

Some institutions have already begun parts of this journey. Trinity Business School has brought climate, nature and health into the spine of its strategy. London Business School has long talked about making meaningful impact on the way the world does business. Others are building institutes and centres to focus on climate and social impact.

Useful but just the beginning. A deeper shift is needed.

The next decade will belong to the universities and business schools that stop treating sustainability as a vertical and start treating responsible capitalism as the horizontal.

Those are the places that will attract students who know they will inherit an entangled world. Those are the places that will generate research with real leverage. Those are the places that will send fusion teams into governments, boardrooms and communities.

The board meeting last week did not solve anything. It did something more important. It asked the right question:

Are we content to be a competent institution with strong sustainability reporting, or are we ready to become a place that helps people think in dimensions we are only just beginning to see?

That is the choice now facing academia.

Complexity is not our enemy.

Our enemy is the reflex to flatten it into something we already know how to teach.

If business schools can learn to sit inside the uncertainty, update at the speed of reality and build true fusion teams, they will not just survive the next decade.

They might actually deserve their influence.

And if fusion teams are the unit of change for what comes next, academia’s responsibility couldn’t be any more clear. It must become the place where this mindset is cultivated, strengthened and renewed. The world needs it. And it needs it now.
