What are systems archetypes and how can they be used to bring a deeper understanding of causal drivers, potential dynamic behaviour in the future, and policy resistance when tackling complex problems, including those in sustainable development?
Systems archetypes are recurring generic systems structures found in many kinds of organisations, under many circumstances, and at many levels and scales. They are distinctive combinations of reinforcing and balancing processes theoretically rooted in systems thinking and modelling.
There are eight common archetypes, each with specific underlying causal drivers (eg., feedback loops, delay), expected dynamic behaviour (eg., acceleration, disruption, tipping point), and policy implications (eg., how to respond, where to intervene). Archetypes can help shift an analytical focus from simple behavioural correlations or a limited understanding of interactions between certain goals to a generalised knowledge of recurring patterns, causes, and consequences.
The eight archetypes are commonly known as:
- Fixes that Fail
- Band-Aid Solutions, also known as shifting the burden or addiction
- Eroding Ambitions, also known as eroding or drifting goals
- Downplayed Problems, also known as growth and underinvestment
- Escalating Tensions, also known as escalation
- Success to the Successful
- Limits to Progress, also known as limits to success or growth
- The Tragedy of the Commons.
We used the complexity of managing interactions between different sustainable development goals (SDGs) that create synergies and trade-offs (eg., poverty, food, well-being, water, energy, housing, climate, and land use) to explore how systems archetypes could provide a deeper understanding, with the results summarised in the figure below.

Causal loop diagrams are used to depict archetypes
Archetypes are usually depicted using causal loop diagrams, which represent feedback relationships among various system elements (eg., different SDGs) and which drive the system’s behaviour over time. Different elements are connected via causal links, shown by arrows, which represent causal relationships.
The causal links are assigned positive or negative polarity to indicate the direction of the relationship between two system elements. A positive relationship implies that a change in the cause variable changes the effect variable in the same direction. A negative relationship implies that a change in the cause variable results in a change in the effect variable in the opposite direction.
A closed chain of causal relationships creates a feedback loop. Feedback loops can be reinforcing (eg., a positive change in one system element leads to a positive change in another, potentially with exponential behaviour) or balancing (eg., a positive change in one system element leads to a negative change in another) over time.
We describe the causal loop diagram for the Fixes that Fail systems archetype using a hypothetical example.
Describing the Fixes that Fail archetype
To reiterate, the Fixes that Fail archetype represents interactions that are driven by the interplay and conflict between (short-term) planned and (long-term) unexpected outcomes of interventions, resulting in unanticipated side effects. The archetype implies that interventions which can positively impact a goal in the short term can sometimes result in unintended consequences and trade-offs with other goals, stopping or even reversing the progress made.
The causal drivers behind this type of interaction involve balancing and reinforcing feedback loops as shown in the figure below (left hand side). Let’s explore this with a hypothetical example in the context of food and agriculture (linked to SDGs 2 (Food Security) and 13 (Climate Action)). Imagine a situation of food insecurity, which is addressed by boosting food production via unsustainable practices, such as agricultural land expansion or excessive fertilizer use. In the causal loop diagram, food insecurity is linked to unsustainable food production practices with a positive polarity (more food security, more unsustainable food production practices). The food production practices do however lead to less food insecurity (negative polarity) leading to a balancing feedback loop, ie., food security is achieved.
However, unsustainable food production practices also have adverse environmental impacts, such as deforestation from agricultural expansion and increasing greenhouse gas emissions from agricultural production. This in turn leads to the adverse impacts of environmental externalities of food production shown in the figure below (left hand side), leading to a reinforcing feedback loop where more adverse impacts lead to more food insecurity which leads to more unsustainable practices and then more adverse impacts and so on.
The potential dynamic behaviour is shown in the figure below (right hand side) which is color-coded to match what is happening in the causal loop diagram on the left. It can be seen that the unintended consequences of unsustainable agriculture increase exponentially over time. For long-term food security, the trend is short episodes of progress improvement due to short-term actions but with a steadily worsening long-term trend due to delayed unintended consequences of those temporary actions. As a result, the original sustainability problems persist and progress is slowed (or reversed) despite increasing efforts.
A policy implication of this interaction archetype is the importance of understanding and preparing for policy side-effects of short-term fixes. In practice, this means whenever temporary, short-term fixes are necessary to address immediate problems, corrective actions should also be taken to mitigate unexpected negative consequences. At the same time, preparing and planning for long-term, high-leverage interventions can also become important to address the main cause of the problems and ensure long-term progress.

Hossein,
Thank you for the article. I came across it while seeking collaborations or opportunities where individuals or institutions require analysis using System Archetypes. I believe that applying System Archetypes can significantly enhance our understanding of the behavior and underlying causes of the Sustainable Development Goals (SDGs). This approach can provide valuable insights into their current status and the obstacles they face.
In my work, I extensively use data to uncover system archetypes. Notably, I collaborated with the government of Botswana to analyze its national unemployment situation, relying solely on archetypes to reveal the systemic nature of its persistent behavior. More details about this work can be found on my LinkedIn profile.
Do you also utilize behavior of data over time graphs in your analysis of archetypes? My email address is: sheilad@strldibw.com

Hi Sheila,
Thank you for your comment highlighting the benefit of using Systems Archetypes to enhance our understanding of the Sustainable Development Goals (SDGs). I reviewed your website and the work you have done—it’s excellent!
There are several tools we could use, but I definitely plan to utilize behavior over time graphs. Other tools include phase diagrams, graphs of variable changes over time or in relation to each other, and various statistical tools if we have sufficient data for analysis (e.g., windowed correlation, etc.).
My goal is always to develop a simulation model from a Causal Loop Diagram (CLD) that aligns with System Archetypes. I believe that an integrated simulation model will combine the impacts from all sectors of the model in one place, allowing us to analyze the effects of different scenarios (& uncertainties) and interventions more comprehensively.
Best regards,
Hossein
Thank you for your response and for reviewing our web material. We appreciate it.
I studied under Dr. Daniel Kim and have been influenced by Peter Senge’s texts. While working with the government of Singapore, I completed a year-long postgraduate program on The Fifth Discipline to prepare us as internal consultants.
Eventually, I branched out from my organization to explore and develop national and global projects using data collected from various platforms, including surveys and census data. This data is critical for creating behavior graphs.
For the national unemployment analysis, I collaborated with Statistics Botswana to gather the necessary behavior graphs. These graphs help us identify which archetypes are at play. The related variables often display similar patterns, allowing us to determine the existence of these structures. My work focuses on understanding the current state rather than predicting or prescribing future behaviours. The graphs reveal the direction in which the patterns are heading. These works fascinate me. Simulation would, of course, tie the work well.
I am seeking more platforms, whether national governments that can provide their data or global bodies such as the United Nations, to use their data to uncover system archetypes and address their resistant issues. These will act as showcases for learners.
Currently, I am looking for project owners interested in exploring global food production, specifically how adopting warm crop production in response to increased weather variability creates a vicious reinforcing cycle. This project will require data from various countries and potentially involve the United Nations FAO. My intention is to showcase the application of system archetypes. More information about my approach to systems thinking can be found here, and the project proposal is available here.
If you believe there is potential for collaboration, I would be happy to share the work completed to date with you and your team. My email is: sheilad@strldibw.com and WhatsApp: +267-75987534

An elegant taxonomy. It might be useful to build a diagnostic matrix as follows. Each vertical column is one of the eight archetypes. Each horizontal row is one of the SDGs, or a sub-goal or program thereunder. In each cell decide a high, medium or low (HML) ranking for the extent of the threat of that archetype to that goal or program. There are many possible combinations from 8 highs to 8 lows so one gets a ranking of sorts.
Wonderful, David! Thank you for sharing your insightful thoughts.
I completely agree with the notion of assessing the synergy or trade-off effects of Sustainable Development Goals (SDGs) and ranking them accordingly. However, I believe it is crucial to quantify the extent of synergy or trade-off, as relying solely on frequency can be limiting. To identify the most impactful actions, we need to go beyond mere frequency and delve into quantitative analysis. In this context, I firmly believe that systems modelling can play a pivotal role. By employing systems modelling, we not only have the means to quantify the effects but also have the opportunity to consider the unique geographical and demographic specifications of various countries and regions. Such an approach allows for a more comprehensive and nuanced understanding of the interconnectedness between SDGs and their implications.
Congratulations to the authors of this work. Ive been aware of the systems archetype ideas for many years but not found great explanations of them. So you have neatly done the important work needed to pull this together and put this in a contemporary light. A great overview and explanation and I look forward to seeing how your work can be turned into practices to strategically support change. You might be interested on another take on archetypes here: https://www.sciencedirect.com/science/article/pii/S2214629622001505. Thanks again. Ioan Fazey
Thanks, Ioan for sharing your work. Look forward to reading it!
Indeed, systems archetypes are invaluable tools for comprehending the dynamic behaviours of complex systems. However, it is unfortunate that these tools are often overlooked by decision-makers and activists. In our paper, we endeavoured to shed light on this issue by providing illustrative examples within the framework of sustainable development goals.
