Change can be expected, envisioned and known, and even created, accelerated or stopped. But change does not always follow a linear and predictable path, nor is it always controllable. Novelty and surprise are inescapable features of life. Non-linear change can involve threats or opportunities.

Although it defines the world we live in, who we are, the outlooks we have and what we do, we often do not relate to non-linear change in a meaningful way. What is holding us back from engaging with it? How do we deal with non-linear change? And what are promising ways forward?

Why is thinking about and anticipating non-linear change difficult?

Generally speaking, non-linearity is difficult to define and conceptualize, because there are multiple interacting forces at the intersection of many domains, manifesting on different spatial and temporal scales and many different actors and (often conflicting) perspectives are involved. As a result, both the nature of change, its underlying causalities, potential chain reactions, and its potential effects are uncertain and at best partially knowable.

Non-linearity is also difficult to grasp because it is about processes and events that may or may not happen. Such processes and events are complex and uncertain and can lead to different perspectives and disagreement between stakeholders. When non-linearity occurs, it may come as a surprise or shock and may have a disruptive effect. It is no understatement to say that we are inexperienced with respect to non-linearity.

Instead, we are much more experienced in reasoning from some evolutionary development. As a result of this general tendency to focus on logical consequences of causal patterns in the past and the present, being confronted with non-linear change may generate insecurity, confusion and a general feeling of discomfort. These feelings can result in ignorance and paralysis of decision making. Thus, refraining from thinking about it makes us vulnerable.

We describe two different, but potentially synergetic, approaches in which detecting and monitoring seeds of change are key: ‘inside-the-system’ and ‘out-of-the-blue’, illustrated in the figure below. Both approaches share the idea that systems can become unstable beyond a critical value. Induced by fluctuations within a system and by external disturbances, a system can instantaneously change. In his book Earth in the Balance (2000), former US Vice President Al Gore uses the analogy of a pile of sand. Dropping one grain after another on a pile of grain does not budge the ‘grain system’. Instead, it slowly builds a stable cone. However, at some point, a critical value is reached, which causes the cone to collapse. Each approach discussed below has a different search light for finding system thresholds and changes.

Finding seeds of non-linear change – ‘inside-the-system’

This approach searches primarily for system indicators that may be an early warning prelude to change and adaptation tipping points. Coherent and longitudinal monitoring of these indicators can help to:

  • create a deeper insight into the system’s dynamics;
  • signal changes that jeopardize (or provide opportunities) for achieving defined objectives in a timely manner;
  • change plans and strategies to continue to achieve the objectives under changed conditions;
  • implement actions not too early nor too late; and to avoid investing too much or too little (Haasnoot et al., 2018).

By focusing on those seeds of change we know relatively well because they are part of the current system – so-called ‘known unknowns’, – we become more conscious about potential new conditions and situations.

An example is adaptive planning in the context of Dutch delta management, where important change indicators include observed and projected sea-level rise along the coast, global mean sea-level rise, storm surge frequency and frequency of alarms to close storm surge barriers.

Finding seeds of non-linear change – ‘out-of-the-blue’

This approach searches for so-called ‘wild cards’: low-probability/high-impact events that may be a prelude to a major, sudden and disruptive break with the status-quo.

Signals of change are found beyond the dominant frames and outside the system. The focus here is on cross-cutting trends and events that may surprise us by coming ‘out-of-the-blue’. We do not know if they may happen, the rapidity with which they may unfold nor their potential effects.

It is, therefore, explicitly not the objective to predict and control such disruptive threats (or opportunities). Instead, this approach is aimed towards:

  • scaling down our blind spots towards our future;
  • becoming more literate in understanding the nature of potential disruptors;
  • being more prepared once our current systems are challenged;
  • avoiding a panic reaction and creating an information and strategic advantage.

These changes are considered ‘unknown unknowns’, but it is possible to imagine what some of these changes could be, such as energy becoming available in a limitless supply, the collapse of a major currency, average global life expectancy increasing to 120 years or a new pest that wipes out grain crops.

Strengths and weaknesses

Both approaches have their own strengths and weaknesses. A risk of the ‘inside-the-system’ approach is that signals that are outside ‘the system’ and that do not fit into a dominant mental frame, remain unnoticed. To avoid tunnel vision, it is important to actively search for signals that could change current paradigms (potential game changers) beyond the system.

A weakness related to the ‘out-of-the-blue’ approach is the difficulty of making a solid link with decision-making.

At the same time, both approaches can reinforce one another: The strength of the first lies in its solid systems knowledge and link with decision-making. The second approach has a strong imaginative potential, that can be used to avoid perceptive and interpretive biases.

Four questions we should ask ourselves to detect change

How can we better integrate both perspectives and create synergies between them? Synergy starts by asking the following four questions:

  • Descriptive: What emergent trends (‘inside-the-system’) and potentially disruptive events (‘out-of-the-blue’) do we see or can we imagine? This involves using both systems knowledge and imaginative power.
  • Estimative: How (un)certain are we? This involves embracing, explicating and using multivocality, instead of assuming consensus.
  • Generative: What is the relative impact? This involves focusing on both direct and indirect effects.
  • Responsive: What can we do in response? This involves linking analysis to action, eg., adapting a plan or strategy, preparatory action, installing/altering a monitoring system, communication about outcomes for awareness raising, and further research.

Monitoring both in and outside the system helps to detect and anticipate change and to prepare in a timely fashion if needed.

Final remarks

Do you have suggestions for other ways to deal with non-linearity? Do you have useful examples where ‘inside-the-system’ and ‘out-of the-blue’ approaches have been successfully used to deal with non-linearities?

  1. Thanks for your post. Mark Bonchek talks about creating an “Exponential Mindset” to help deal with non-linear change or progress. His article is within this post: https://cuttingedgepartnerships.blogspot.com/2016/08/get-most-out-of-partnerships-latency.html As you say, being able to scan the external and internal environment is essential for picking up feedback about significant developments and changes that could affect and shape ongoing progress and innovation, etc. Central to this scanning is being able to listen to noise and manage fluctuations. I explore this and provide some examples of when this has and has not happened here: https://cuttingedgepartnerships.blogspot.com/2016/03/listen-to-noise-and-manage-fluctuations.html

  2. Thanks for the concise approach to the topic – During the research for my master thesis ‘Effects of deep uncertainty on firm risk management’ I was astounded by the level of ignorance/ lack of consideration for deep uncertainty/non-linear, low probability – high impact effects by firms.

    The ‘inside-the-system’ change/event appears to be covered (at least from the perspective of firms) by an ever-greater data collection that is then analysed based on algorithms and ‘AI-based’ analytics, which both entail built-in biases that are most often not reflected upon. Leaving this approach as sub-optimal but highly sellable.

    I think the questions you raised at the end of this article are excellent starting points. Especially the point ‘Estimative’ is intriguing as it appears to be the approach that is most ready-made for quantification and as quantification/data-driven analytics are currently the most widely accepted basis for decision making in firms – it could serve as a starting point for more widespread adaptation.

    I find the whole topic-complex fascinating – but sadly its lack of adaptation in the area of private businesses offers no pathway to make this fascination into a career.

    Thanks again for the article

    • Thanks a lot! I share your observation that many people/organisations are still inexperienced in and often reluctant to engage in dealing with non-linear change and ‘unknowns’. It asks for a different mind-set: when uncertainty is considered limited or the dimensions of uncertainty are perceived to be well-understood, it makes sense to resort to mainly quantitative approaches (e.g. based on linear extrapolation, trend-based and a forecasting way of representing uncertainty). However, for dealing with non-linear change and ‘unknowns’, data cannot be gathered, nor analyzed in a classical sense. This also means that when you want to ‘estimate’ uncertainties regarding newly emerging phenomena, you have to think about alternative ways to construct evidence and solidity (and comfort for that matter). Not instead of quantification and data-driven analysis, but in addition to it! I hope we have provided some useful vocabulary and a starting point for a more widespread adaptation.

  3. A very thoughtful piece from a very high level. I have always wondered about how an organization keeps up-to-date information about what is going on in the internal level. The news about Boeing’s corporate culture makes me wonder if people at the top can really knew what was happening and how an internal crisis (like two crashes) can change the whole thing. I think Boeing tells us that many things cause something that was an unknown (or at least an unacknowledged unknown). Can a large organization come to grips with what is really going on if managers only send up good information? Or are these organizations just bound to comes to grips with unknowns sooner or later? And when the bad stuff happens, do they respond by saying, “i didn’t know”? But how could you know what is happening in a large organization? How do you look for those grains of sand? Thank you again for a very interesting piece.

    • Thanks Patricia. In our blog post we mainly focused on the ‘external level’: we tried to present an alternative approach and useful vocabulary for identifying shocks and mutations in the dynamics of systems and contextual trends and developments. I totally agree that the internal level is highly relevant here. To be able to deal with non-linear change, you need to invest in the strategic competence of your organization and the capacity to translate relevant information into policy, strategy and/or innovation. In this process, there may be many cognitive, perceptual and interpretive biases at work. Interesting in this context is, for example, the work of Ansoff (1979, 1984) and Senge (1990), who have written about the role of filters and mental models and the way they hamper our sensitivity towards and receptiveness of new kinds of information and information flows in organizations in general. In this blog post series, also Smithson has shared interesting viewpoints on this topic! Another piece of literature that I found very inspiring in this is the book ‘The Challenger Launch Decision: Risky Technology, Culture, and Deviance at NASA’ of Diane Vaughan! She analyzed the work group culture and the environment in which experts (NASA engineers and managers) work: how they negotiated risk and took decisions under uncertainty. It gave me new and valuable insights into how to look for those ‘internal’ grains of sand .

  4. Thanks for sharing, it is very helpful, although I must still read it a few more times. The rate of change can have have a negative or positive impact on the mental ability to react and make decisions. When immature leaders and managers, as part of a system, cannot assess and cope properly, it can paralyze the system. This is all I that I can add, Susan and Marjolijn.

    • Thanks, Quinton, for your interesting feedback. In our work, we tend to focus on the question how to get timely and reliable signposts that are convincing for decision-makers, leaders and managers to act upon. And here, indeed, the mental ability to react and make decisions is very relevant as well! Thanks for mentioning this!
