The HSD Theory of Change
This is the fifth article in my 8-week series exploring foundational systems thinking concepts, written for the 2025 RE-AMP Systems Thinking Academy. Whether you’re following along with the series or diving deep into systems practice, this article explores the bridge from understanding complexity to engaging it through Adaptive Action and Pattern Logic.
Â
So far, we’ve explored how individual cascades of inference shape our perceptions, how collective paradigms create systemic patterns, and how human systems behave as Complex Adaptive Systems (CAS) — flowing between states of stability and emergence.
These have all been ways of seeing: seeing our own mental habits, seeing the paradigms that shape our systems, and seeing the living dynamics of complexity.
But now, we arrive at a turning point.
This is the moment where systems thinking shifts from insight to engagement. From perceiving the dance, to joining it. We begin to ask:
How do we participate wisely in complexity?
How do we shift not just our minds, but our moves?
How do we influence what emerges — without control, without certainty — but with care, rhythm, and intention?

Introducing the HSD Meta-Approaches
Many frameworks offer tools for navigating complexity. Each brings insight. Yet the very nature of living systems — messy, dynamic, emergent — resists tidy models.
The Human Systems Dynamics (HSD) Institute offers something different: not a fixed map, but a way of moving.Â
At the heart of HSD are two foundational meta-approaches: Adaptive Action and Pattern Logic.
These are not techniques to overlay on a system from the outside.
They are embodied practices for engaging from within — attuning to the dynamics of a system as they unfold, and responding with clarity, creativity, and care.
Rather than seeking to predict or control, these meta-approaches help us develop the relational reflexes we need to navigate complexity on its own terms — working with living dynamics rather than against them.

Adaptive Action: Consciousness Within Complexity
Adaptive Action gives us a simple but powerful rhythm for engaging complexity:
What? → So what? → Now what?
This cycle helps us become more conscious in real time — interrupting the cascade of inference we explored in Article 1. Instead of tumbling unconsciously from perception to action, we pause. We notice. We ask. We choose.
In complex environments, rigid plans quickly crumble. Adaptive Action encourages small, iterative cycles of sense-making and action: Observe. Reflect. Act. Then observe again.
This rhythm slows down the automatic rush from perception to action. It helps us:
- Intentionally expand and deepen our initial observations — broadening our focus beyond our default filters, using Pattern Logic to notice what’s been outside our habitual attention
- Enrich our interpretations by attending to more of the system’s context, allowing assumptions to shift naturally as old mental habits are unlearned
- Discern next steps with greater awareness and alignment to what’s unfolding
- Choose our next move with greater presence and coherence
Importantly, all three steps of Adaptive Action — “What?”, “So what?”, and “Now what?” — are deeply context-sensitive.
In simpler contexts, clarity comes more easily and direct solutions may suffice.
In more complex or unstable environments, our observations must expand, our interpretations deepen, and our moves become lighter, more exploratory — seeding conditions rather than forcing outcomes.
Adaptive Action reminds us that change in living systems is never linear. We learn forward — through cycles of action and reflection — adapting as the system itself evolves.

Pattern Logic: Seeing the System Whole
Adaptive Action offers us a rhythm; Pattern Logic reshapes our sightlines. It asks us to unlearn old habits of focus and build new ways of seeing — attuned to interconnection, flow, and the deeper structures shaping systems.
Rather than focusing narrowly on isolated events or agents, Pattern Logic invites us to step back and perceive the wider field — the relationships, interactions, trends, and emerging patterns that shape systemic behavior.
It’s the difference between counting trees and sensing the forest.
Pattern Logic asks:
- What recurring patterns or forces are shaping the system?
- What constraints are limiting or channeling its behaviors?
- What relationships seem particularly significant?
- What trends are emerging across different scales?
Depending on the context — as we learned from the Stacey Matrix — our pattern sensing may focus on different phenomena. In stable zones, we may look for reinforcing “recipes for success.” In emergent zones, we must attune to weak signals and early shifts.
Crucially, Pattern Logic reminds us that living systems cannot be forced to change through linear cause-and-effect. Instead, we cultivate conditions, notice what emerges, and gently nudge the system toward more life-affirming patterns.

The Dance of Conscious Action and Pattern Sensing
The HSD theory of change rests in this living dance:
- Complex Adaptive Systems teach us that change flows through patterns of interaction — inviting us to work relationally, not mechanically.
- Adaptive Action slows our mental habits, inviting more conscious engagement and iterative action.
- Pattern Logic retrains our field of perception.
Together, these shift us from reactive participants to intentional stewards of systemic evolution.
There are a lot of approaches to systems thinking. Most of them involve a framework or a model of some kind. After you’ve been at this for awhile you start to notice that the essence of all of them is this combination of slowing down and pointing our attention in new ways – i.e. training ourselves to see patterns from one angle or another. The complexity can be overwhelming at first, but in the end, it’s this simple – every method or model or framework boils down ‘slow down, examine the patterns, make some kind of sense of those patterns, do some small thing, and examine the patterns again.’
Every method we explore from here is designed to strengthen these two capacities.
Because ultimately, systems change is not something we impose. It is something we participate in — with attention, patience, and presence.

Why this matters when working with complex systems
This article marks a turning point in our series: the shift from understanding complexity to participating in it.
- It names the two meta-approaches that quietly underlie everything else in this series: Adaptive Action and Pattern Logic.
- These aren’t tools we pull out for special occasions. They’re ways of being in complexity — ways of seeing, sensing, acting, and learning in motion.
- This model helps us stay present in systems that won’t hold still. It gives us a rhythm for engaging change without pretending to control it.
- It also introduces a powerful reframing: That systems change is not a top-down intervention, but a living participation — a practice of sensing patterns and shaping possibility, together.
This is the hinge. Everything that follows builds on this foundation — not just as theory, but as practice.
