In Complex Situations Cause and Effect Can Only Be Understood in Retrospect Why prediction breaks down in complex situations

We often assume that if we understand causes, we can predict outcomes. In complex situations, cause and effect are only clear in retrospect, so prediction can mislead and overconfidence can grow. Working with small experiments, noticing emerging patterns, and adjusting as we go offers a more grounded way forward.

We are used to thinking that if we understand the causes, we can predict the effects. Much of management, strategy, and everyday decision-making rests on that assumption. It feels rational, orderly, and reassuring.

But that assumption only holds in certain kinds of situations.

Dave Snowden, through the Cynefin Framework, offers a way of making sense of this. Cynefin is a simple sense-making model that distinguishes between different types of contexts, from those where cause and effect are clear and repeatable, to those where they are not.

In the complex domain, the one most of us inhabit far more than we realize, cause and effect are only understood in retrospect.

This is a simple statement, but it carries quite radical implications.

The illusion of foresight

In ordered environments, things behave predictably. If a machine breaks, we can trace the fault, and if a process fails, we can analyze and fix it. Here, cause and effect are either obvious or can be discovered through expertise and analysis. This is the world where planning works, best practices make sense, and predictions are meaningful.

But in complex environments, the situation is different. Patterns do exist, but they are not visible in advance and only become clear after the fact. We look back and say, “Of course, that’s what happened,” but that clarity is retrospective, not predictive. We mistake our ability to explain the past for an ability to predict the future.

Why explanation is not prediction

One of Snowden’s key points is that complex systems are composed of many interacting elements that change in response to one another. People adapt, contexts shift, and new factors emerge. Because of this, the system is constantly evolving.

Even if we can explain what happened yesterday, the conditions that produced that outcome have already changed. Explanation, therefore, does not translate into foresight. This is why attempts to impose linear cause-and-effect thinking on complex situations often fail. We assume that repeating the same actions will produce the same results, but the system is no longer the same.

Acting without knowing

If cause and effect can only be understood in retrospect, the question becomes how to act. Snowden’s answer is not to abandon action, but to change its nature.

Instead of analyze, decide, implement, we move to probe, sense, respond. We take small, safe-to-fail actions, watch what happens, and adjust accordingly. We amplify what works and dampen what does not. In this way, we learn our way forward rather than plan it.

The danger of premature certainty

A common failure mode is what Snowden calls premature convergence. We take a complex situation, impose a simple explanation, and act as if the world were predictable.

This often shows up as an overreliance on best practices, copying what worked elsewhere, or deferring too quickly to expert opinion. All of these assume stable cause-and-effect relationships. In complex contexts, that assumption is fragile. Once an explanation takes hold, it tends to be defended, even as reality shifts.

Conversation as a way of seeing

This is where conversation becomes central. If patterns only emerge in retrospect, then making sense of them is not an individual activity; it is collective.

Different perspectives reveal different aspects of what is happening. Weak signals are more likely to be noticed, and interpretations can be challenged and refined. From a Conversational Leadership perspective, the role is not to provide answers, but to create the conditions in which multiple interpretations can surface and interact. The aim is to avoid closing things down too early and to stay with the unfolding pattern.

A different relationship with the future

Taking this seriously changes our relationship with the future. We cannot fully predict outcomes or map cause and effect in advance, but we are not without influence.

We can design experiments, shape constraints, and influence the direction in which things evolve. The future is not something we forecast with precision. It is something that unfolds through interaction.
