Imagine influencing an entire system—be it an organization, a city’s transportation network, or even the global economy—by making just one small change. This is the power of leverage points. Coined and popularized by systems thinker Donella Meadows, leverage points are specific places within a system where a small shift can lead to significant, often transformative, results.
Systems are all around us, from markets and governments to ecosystems and communities, but they’re often complex and difficult to change. Donella Meadows’ groundbreaking essay “Leverage Points: Places to Intervene in a System” provides a framework for understanding how and where to intervene to make meaningful improvements. Leveraging these insights has become foundational for policymakers, educators, business leaders, and systems practitioners alike.
This blog post will explore Meadows’ 12 leverage points, the critiques and advancements in leverage points theory, and actionable guidance on how to use these principles to drive effective change
What Are Leverage Points?
Leverage points are specific spots within a system where strategic changes can dramatically influence the system’s behaviour. Think of a thermostat controlling the temperature of a building. Adjusting the thermostat slightly can have far-reaching effects—changing the temperature for everyone inside. Similarly, in larger systems, making even a small tweak in the right place can lead to disproportionate impacts.
Donella Meadows’ work identified twelve leverage points, varying in effectiveness. These points range from simple parameters (e.g., changing tax rates) to deep structural elements, such as shifting societal paradigms. Meadows ranked these interventions by their potential impact, with the deeper leverage points—focused on structure and intent—being more powerful drivers of change.
Why It Matters?
Leverage points matter because they offer a powerful way to understand how to create significant and lasting change in complex systems. Identifying and intervening in these points, even small shifts can lead to large-scale impact. Leverage points help us move beyond superficial solutions and focus on the underlying structures and dynamics that drive a system’s behaviour, leading to more effective and sustainable change.
Effectiveness: Targeting leverage points can be far more effective than changing everything at once. We can maximize our impact and create more sustainable change if we direct efforts on these strategic points.
Strategic Thinking: Leverage points encourage us to think systemically and allow us to look beyond superficial solutions. They challenge us to consider the underlying structures and dynamics that drive a system’s behavior.
Empowerment: Identifying leverage points can empower individuals, communities, and organizations to create change, even in seemingly intractable situations. It provides a sense of agency and hope.
Meadows’ 12 Leverage Points Explained
Meadows identified twelve leverage points, ranked from the least to the most effective in terms of creating change:
- Constants, Parameters, Numbers
Adjusting numbers, like tax rates or speed limits, is common but rarely leads to lasting change. Unless these adjustments trigger shifts higher up in the system, their impact is shallow.
- The Sizes of Buffers and Stabilizing Stocks
Buffers (e.g., the reserve capacity of a power grid) can enhance stability, but oversized buffers can make a system rigid, while undersized buffers leave it fragile.
- The Structure of Material Stocks and Flows
Physical infrastructure, such as roads or supply chains, is difficult to alter once established because it’s expensive and time-consuming to redesign.
- The Lengths of Delays
Changing the time it takes for feedback to loop through a system (e.g., how long it takes policies to show their effects) can improve decision-making. However, long delays could cause oscillations and instability.
- The Strength of Negative Feedback Loops
Negative feedback is critical for self-regulation (e.g., a thermostat balancing room temperature). Strengthening these loops can stabilize systems, but they must be carefully calibrated.
- The Gain Around Positive Feedback Loops
Positive feedback loops amplify change (e.g., compound interest intensifying wealth gaps). Reducing runaway positive feedback is essential for maintaining balance.
- The Structure of Information Flows
Who has access to what information shapes decision-making. Better transparency, like putting calorie counts on menus, often leads to behavioral shifts.
- The Rules of the System
Rules determine system behavior (e.g., regulations in financial markets). Those who make or enforce the rules wield immense influence.
- The Power to Self-Organize
Systems that can evolve their structure (e.g., ecosystems or open-source platforms) are resilient. Encouraging adaptability creates systems better able to respond to change.
- The Goals of the System
Shifts in a system’s objectives (e.g., PepsiCo focusing on healthier products) can dramatically change the behavior of all its components.
- The Mindset or Paradigm Out of Which the System Arises
Paradigms shape how we understand and interact with the world. For example, moving from a belief in unlimited economic growth to sustainability reorients entire systems.
- The Power to Transcend Paradigms
The deepest leverage point is the ability to step back and see all paradigms as constructs, which opens the door to entirely new ways of thinking. Transcending paradigms enables innovation at its core.
Advancements in Meadows’ 12 Leverage Points
Donella Meadows’ 12 leverage points are a great way to understand how to make changes in complex systems, like governments, schools, or even the environment. Scientists have found ways to improve her ideas, making it easier to use them for real change. A big improvement comes from Abson and his team in 2017. They sorted Meadows’ leverage points into four big groups to simplify things. These groups are Parameters, Feedbacks, Design, and Intent.
Each group shows a different way to make change, depending on how deep into the system you go. Some are simple, while others are harder to change but can make a bigger difference.
Parameters: These are the most tangible and easily adjustable aspects of a system, such as taxes, subsidies, or standards. While parameter adjustments can influence behavior, they often result in incremental rather than transformative change because they don’t address the underlying structures and goals of the system. For example, setting targets or providing financial incentives within existing structures, such as carbon pricing, green taxes, or protected area targets, might achieve specific outcomes but may not fundamentally alter unsustainable trajectories.
Feedbacks: Feedbacks involve the interactions and information flows within a system that influence its behavior. Understanding and modifying these feedback loops can be more effective than simply tweaking parameters, as they can help to shift the system’s dynamics. For instance, providing more information about the impacts of climate change might lead to greater awareness and potentially shift behaviors, though it may still not alter the overall intent of a system.
Design: This category encompasses the structure and organization of the system itself, including the rules, power dynamics, and institutions that shape its behavior. Interventions targeting design can lead to more significant changes by altering the fundamental framework within which the system operates. For example, redesigning institutions to be more open to learning and adaptation in the face of crises can create pathways for transformative change.
Intent: This is the deepest level of leverage and encompasses the overall goals, paradigms, and mindsets that drive the system. Shifting the intent of a system is the most challenging yet potentially the most transformative intervention. It requires addressing the fundamental values and beliefs that underpin the system’s direction. For instance, transforming the global food system to prioritize food security for all would require a significant shift in intent, moving beyond a focus on production to address the underlying structures, values, and goals shaping food systems.
| Parameters: The relatively mechanistic characteristics. Typically targeted by policy Makers. | 1 | Constants, parameters, numbers (such as subsidies, taxes, standards). |
| 2 | The sizes of buffers and other stabilizing stocks, relative to their flows. | |
| 3 | The structure of material stocks and flows (such as transport networks, population age structures). | |
| Feedback: The interactions between elements within a system of interest that drive internal dynamics. | 4 | The lengths of delays, relative to the rate of system change. |
| 5 | The strength of negative feedback loops, relative to the impacts they are trying to correct against. | |
| 6 | The gain around driving positive feedback loops. | |
| Design: The social structure and institutions that managing feedback and parameters. | 7 | The structure of information flows (who does and does not have access to information). |
| 8 | The rules of the system (such as incentives, punishments, constraints). | |
| 9 | The power to add, change, evolve, or self-organize system structure. | |
| Intent: The underpinning values, goals and world views of actors that shape the emergent direction to which a systems is oriented. | 10 | The goals of the system. |
| 11 | The mindset or paradigm out of which the system — its goals, structure, rules, delays, parameters — arises. | |
| 12 | The power to transcend paradigms. |

Why This Categorization Matters?
What makes Abson’s work special is the idea that deeper changes—like focusing on intent—can have a much bigger and more lasting impact. They also noticed that these categories are connected. For example, the purpose (intent) of a system influences its design, and the design affects the feedbacks and parameters. This means we need to think carefully about the whole big picture when we want to fix something.
Also, leverage points can show up at many levels in the system. This means we can work on change in small ways, big ways, or even at local and global levels at the same time.
Abson et al.’s categorization of leverage points into parameters, feedbacks, design, and intent offers several advantages over Meadows’ original 12 leverage points by providing a more structured and strategic framework for understanding and intervening in complex systems.

Critiques of Donella Meadows’ 12 Leverage Points
While Donella Meadows’ 12 leverage points have been influential in the field of systems thinking, several critiques have emerged over time. Here are some key critiques of Meadows’ 12 leverage points, drawing on the provided sources and our conversation history:
Lack of Empirical Evidence: Meadows acknowledges in her original article that her list of leverage points arose from personal experience and insights gleaned from systems analysis, rather than rigorous empirical testing. She explicitly calls it a “work in progress” and an “invitation to think more broadly about system change.” This lack of substantive evidence and justification has led to questions about the validity and universality of the proposed hierarchy.
Overemphasis on “Deep” Leverage Points: Meadows places significant emphasis on the power of changing paradigms and transcending paradigms as the most effective leverage points. Sometimes, the most important ways to make big changes are hard to influence and don’t have clear steps to follow. Critics say that focusing too much on these deep changes can cause people and organizations to feel stuck or frustrated because they can’t find practical ways to start making a difference.
Deterministic View of Systems: Meadows’ framework, which is based on systems dynamics, sees systems as mostly predictable and determined. Critics say this view makes things too simple and doesn’t consider the complexity of social-ecological systems. They argue that it ignores important factors like human choices, power struggles, and unexpected events that can affect how a system behaves in surprising ways.
Neglect of Context and Power Dynamics: The original 12 leverage points are shown as a clear order, but they don’t take into account the different situations and power relationships that exist in various systems. Critics say that we need to recognize that leverage points can change based on the specific system and its special traits. It’s also important to understand how power dynamics affect how easy or difficult it is to make changes at different leverage points. This understanding is key to making effective improvements.
Future Direction for leverage points.
While Meadows’ work laid a strong foundation, she openly acknowledged it as a work in progress—an invitation for further exploration, critique, and nuance. Building on this discourse, Ryan J.A. Murphy, in his presentation “Finding Leverage for Systems Change,” highlights additional pathways for advancing our understanding and application of leverage points, offering valuable insights into how we might drive meaningful systems transformation.
Expanding Beyond System Dynamics: The future of leverage points could be expanding their scope beyond the traditional boundaries of system dynamics. This involves exploring new ways to conceptualize and apply leverage points in various contexts.
Evaluating Leverage Points: One gap in Meadow’s framework is the lack of tools to evaluate the effectiveness of different leverage points. A future-oriented approach might include developing robust systems for leverage analysis. This could involve assessing system response through simulations, pilot programs, and predictive models.
Recursive and Relative Leverage: Two important dimensions of leverage currently gaining attention are recursiveness and relativity: Recursive leverage means that leverage points themselves are nested systems. Once identified, they can be further broken down into smaller leverage points for greater precision. For example, if “changing the rules” is identified as a leverage point, exploring how those rules are made or enforced could uncover even more actionable changes.
Relative leverage highlights that the most effective leverage point may not always be accessible or obvious. Often, to get to a powerful leverage point, it is necessary to first influence a more accessible, indirect point.
This iterative exploration not only respects the complexity of systems but also reduces blind spots in systems interventions.
The Narrative Role of Leverage Points : Framing also matters. Identifying and communicating leverage points can serve as a powerful means of engaging stakeholders in conversations about systems change. Narratives around leverage points can generate shared understanding and align stakeholder goals more effectively.
For instance, framing a leverage point as a way to foster equity in access to healthcare might not only mobilize resources but also bring diverse stakeholders into the fold. Understanding how to craft and utilize these narratives will be essential to systemic design.
The future of leverage points research lies in breaking free from oversimplified views of systems and interventions. Designing for real-world change requires critical and nuanced approaches that challenge existing paradigms.
By developing modern theories of change, embedding culture and narrative into our frameworks, and committing to ethical practices, we can better equip practitioners to address the pressing challenges of the 21st century.

Conclusion
Leverage points, first introduced by Donella Meadows and later expanded by Abson et al. (2017), provide a practical way to understand and influence complex systems. They help pinpoint areas where small, focused actions can create big, meaningful changes—whether through minor tweaks or deeper transformations in goals and mindsets. While the framework has its challenges, like being abstract or less adaptable to specific contexts, it encourages us to think beyond surface-level solutions. Shifting our focus to these key areas of change opens the door to fresh ideas, innovative solutions, and the opportunity to reimagine systems for a better and more equitable world.
