Core Idea

Change is the transition of a system from one state to another. As a mental model, the insight isn't that change happens — it's that systems resist it. Every stable system has developed equilibria, feedback loops, and structural inertia that fight to maintain the current state. Successful change requires overcoming these forces, which means understanding what holds the current state in place before attempting to move to a new one. The model teaches that the difficulty of change is proportional to the depth of the equilibrium you're disrupting: surface-level changes are easy; structural changes require proportionally greater force, time, or both.

How to See It

Organisations
You're seeing it when a company announces a major restructuring but six months later everyone is still operating exactly as before. The formal structure changed, but the informal systems — habits, relationships, incentives — held the old state in place.
Markets
You're seeing it when a superior technology struggles to gain adoption because the existing ecosystem — distribution, training, integrations — creates massive resistance to switching. The market's equilibrium resists the change.
Section 3

How to Use It

Before attempting change, map the forces maintaining the current state. What incentives, habits, structures, and relationships hold things in place? Then determine whether you can alter those forces or must overpower them. Small changes in the maintaining forces often produce larger results than brute-force pushes against the system.
Decision filter
"What forces are maintaining the current state? Can I change those forces, or must I overpower them?"
As a founder
When you need organisational change, start by understanding why the current state persists. Change the incentives, defaults, and structures that hold the status quo in place. Don't just announce the new direction — dismantle the scaffolding that supports the old one.
Section 5

Founders & Leaders

Andy GroveCEO, Intel
Grove navigated one of the most dramatic corporate changes in history — pivoting Intel from memory chips to microprocessors. He didn't just announce the shift; he systematically dismantled the forces maintaining the old state. He redirected capital allocation away from memory, restructured reporting lines, and reframed Intel's identity from a memory company to a processor company. His famous "strategic inflection point" framework was built on understanding change dynamics: the environment shifts, the old equilibrium becomes untenable, and the company must find a new one before the old one collapses. For founders, Grove's lesson is clear: change succeeds when you alter the system's underlying forces, not just its surface declarations.
Section 7

Connected Models

Tension
Inertia
Inertia is the force that resists change — objects in motion stay in motion, objects at rest stay at rest. Change must overcome inertia, and the magnitude of inertia determines how much force change requires.
Reinforces
Paradigm Shift
A paradigm shift is a specific type of change — one that alters the fundamental framework of understanding. Change explains the mechanics; paradigm shift describes the most transformative variety.
Pairs-with
Le Chatelier's Principle
Le Chatelier's Principle states that systems under stress will shift to counteract the change. This explains why imposed changes often trigger compensating reactions — the system fights to restore its original equilibrium.
Section 8

One Key Quote

"There is at least one point in the history of any company when you have to change dramatically to rise to the next level of performance. Miss that moment, and you start to decline."
— [Andy Grove](/people/andy-grove)
Section 11

Summary & Further Reading

Change is the transition from one system state to another, resisted by the equilibria, feedback loops, and inertia that maintain the current state. Successful change requires understanding what holds the current state in place and altering those forces — not just pushing against them.

Frequently asked questions

What is Change?

Change is a mental model used for better thinking and decision-making.

How do you apply Change?

To apply Change, identify situations where this framework is relevant, then use it as a lens to evaluate your options and decisions. The model is most useful when combined with other complementary mental models.

What category does Change fall under?

Change falls under the Systems & Complexity category of mental models. Other models in this category can be found on the Systems & Complexity hub page.

Why is Change important?

Change is important because it provides a structured way to think about problems that would otherwise be approached with intuition alone. Understanding this model helps you avoid common reasoning errors and make better decisions.
