The inundated delta

April 30, 2026 By Chris Corrigan Art of Harvesting, Art of Hosting, Complexity, Containers, Emergence, Facilitation, Featured 5 Comments

Over the past several weeks, Dave Snowden has been writing a very extensive series of long blog posts that serve as a watershed declaration of the state of his work thus far in the field of anthro-complexity. The posts both define what the field is and make sharp distinctions about what it isn’t, especially in relation to practices, ontologies, and theories that sit adjacent or close to it. I believe this represents a moment where Snowden is making a strong declaration about what anthro-complexity is, and being very deliberate about pulling it back from interpretations that seek to fit it into pre-existing understandings of complexity. Anthro-complexity is a new approach to complexity in human systems, and these posts are a strong statement of what that is.

In the course of these posts, Dave has focused in part on the Art of Hosting, among other approaches to working in complexity, and has named me explicitly as someone who has been trying to work within the field of the Art of Hosting to bring my own practice more in line with what I have been learning about anthro-complexity over the past 15 years or so, since I was introduced to Cynefin.

The entire series is very important to understand the context, and it is very long and dense stuff, but it’s important to understand some of the context. You can start the most recent series on the channel and the estuary here. For these posts I am going to write, I encourage you to read the two most direct posts about the Art of Hosting:

  • Stacy Unresolved
  • Leadership in the Estuary

These posts have helped me to reach an important moment in my own thinking, and I promised to respond to them personally and messily, so I’ll do my best here, probably in a series of posts. I am just heading out on a three-and-a-half-week walking holiday, so I’m not sure how much I’ll be able to get to, but long walks do offer a chance to ruminate.

So here is the first of what will likely be a number of posts on this topic.

First, thank you, Dave, for naming me, and for naming the Art of Hosting as a practice field, and for putting some deeply important questions to me and to us. These are questions that help guide and deepen our understanding of the field we work in. The Art of Hosting field is a broad one, spanning every continent, made up of people who arrive from many different traditions and levels of experience in the worlds of facilitation and change-making. Originally, the field was formed by folks moved by their experiences in social change, new metaphors of organizational leadership and systems change, and large-group facilitation methods. We are, and always have been, a community of practitioners first, and so the field has taken on the feel of a place where methods and tools are top of mind. I think the world sees the Art of Hosting as a collection of tools and practices for convening dialogue, and I don’t think that is incorrect. But it presents a problem that Snowden has identified, and it’s one we have to deal with.

The basic problem is this: while we use the language of emergence and complexity in the Art of Hosting, our use of methods and pre-designed processes, and our emphasis on “hosts,” means that we run the risk of not always being coherent with our own claims about emergence. Our approach to hosting conversations that matter certainly acknowledges emergence and can create conditions in which emergence happens, but it does that largely because humans operating in any constraint regime will create emergent outcomes. The question is whether that emergence is relevant to the field out of which these people come, or whether it is a distortion brought about by the container in which people are gathered and in which we convene conversation. A powerful conversation on its own is not helpful if its effects cannot survive contact with the system that it seeks to change.

The critique is important because it raises a question of epistemic justice, and I don’t think we answer that question very well: whose knowledge is being surfaced, and under what conditions? Are we enabling the distributed intelligence of the system to become visible, or are we shaping what can be said and heard through the design of our processes, invitations, and harvests?

If the conversations we convene are to truly matter, they must be coherent with the field in which they are situated. More than that, whatever emerges in those conversations must be able to travel back into that field and interact with it: shifting patterns, enabling action, and surviving beyond the temporary conditions of the container.

The issue, then, is not whether to convene, but how to do so in ways that remain accountable to the field. We need to be aware of the constraints we introduce, conscious of the power we hold as hosts, and attentive to whether what emerges is actually usable once people return to the systems they inhabit. And we need to be constantly critiquing our positionality.

Dave’s work lately has been to discuss systems as geological features. He locates the work of anthro-complexity firmly in the metaphor of the estuary, and yesterday his post very helpfully described the Art of Hosting (as a body of work) as a delta. These are two different kinds of systems, and the distinction is important. I want to quote from that post at length:

Art of Hosting is the delta of the leadership and organisational field. Over two decades and across dozens of cultural contexts, Toke Møller, Monica Nissen, and the community they built have produced real moments of collective intelligence, genuine emergence, and authentic contact. The practice carries real generosity and real craft, and this post takes that seriously.

But the delta has been building. The hosting aesthetic, the circle, the open space, the world café, the council, the harvest: these are now a recognisable repertoire, instantly legible to anyone who has spent time in that world. And a repertoire is a structure that precedes the encounter. The hosting team designs the invitation, shapes the container, holds the process, and harvests the outputs. The circle looks leaderless. The architecture is not.

Chris Corrigan, who has engaged generously with this argument in previous conversations and stated plainly that he is trying to change Art of Hosting from within, deserves acknowledgement here. That is the most intellectually honest position available to a practitioner committed to a tradition they have also diagnosed. It is exactly the move Griffin made with Stacey and the matrix: following the argument toward its conclusion, regardless of the professional cost. The question is whether the tradition as a whole is willing to follow that argument, or whether the delta will continue to accumulate.

The delta’s generativity is real. The flood plain moments, the occasions when Art of Hosting breaks through its own container and something genuinely distributed happens, are not accidental. They are what the tradition has been reaching for, and they occur. The problem is that the method cannot reliably produce them, cannot fully explain when they occur, and cannot sustain them when they do. The hosting team is still in the room. The design is still prior. The harvest is still shaped by hands that arrived before the conversation began.

In order to fairly deal with this critique we must honestly look at the ways in which it is true. And so to all my friends and colleagues in this field, I invite you and us to find the genuine questions in here that help us deepen our practice and rise to the challenge posed by serious questions of epistemic justice, legitimate change, and a deeper understanding of complexity and its dynamics.

My experience of reading Dave’s posts lately has been at times feeling a bit defensive but on the whole (and especially after yesterday’s) more akin to what a delta might feel during and after an autumn king tide, when it is overwhelmed and inundated by the sea and the rain. When the deluge stops and the tide ebbs, one finds that the landscape has been gently rearranged and new patterns of flow and precarious stability arise. I find myself in somewhat familiar location, but standing on new ground and needing to re-navigate and re-orient myself and my practice. I genuine experience of estuarine thinking. As I have been doing so over the past few days (during which I was also co-leading an Art of Hosting training) I found myself operating with heightened curiosity and inquiry.

I’ll write more about these questions, and especially as they relate specifically to how I understand the practice of the Art of Hosting, the usefulness of methods (including harvest), the importance of dialogic containers and how anthro-complexity helps us make better change. Stay tuned, and enjoy the view.

    Gosh, Chris; so much food for thought here. Just a few quick thoughts:

    1. What is “emergence” really?
    Is it what we often say in the Art of Hosting — a higher-order new value that sets the direction for aligned action? Or is emergence whatever new patterns are noticed? Or something else completely?
    One thing I deeply appreciate about AoH is “purpose as the invisible leader.” Sometimes that purpose is to find alignment on a bounded topic (like a local drug situation), and when a multi-stakeholder group reaches a coherent action, the impact is undeniable.

    However, we also have the “intangible harvest”: the trust built, the wider pictures seen, the allyships forged. These can lead to a post-workshop cup of coffee and a “game-changer” initiative that no one planned.
    Looking in this way, workshops are always unbounded, even within a structure. This intangible piece is incredibly powerful — it is the fertile soil for systemic emergence — and I wonder if it perhaps sits outside of Dave’s typical frame of thinking.

    2. From aligned action to maybe “islands of action”?
    I’m wondering: instead of pushing for a major aligned action forward, could we more prominently host the group to identify different “islands of action”, ie small prototypes? (we do that often, but this exchange leaves me thinking to do it more.)
    We could then ensure that the group reconvene e(perhaps with a host, perhaps without) to review how those prototypes have done and decide on the next iteration. Could this “Estuarine” approach — managing small, distributed experiments — play a more prominent role in how I talk & consult & scope to/with my potential clients?

    3. The microcosm of the hosting team
    There is never just “a host” in the middle. In AoH, we try to have a microcosm of the whole system represented in the hosting team. This means the team is more attuned to the real dynamics of the room than a traditional “outcome-oriented facilitator” would be. This shared hosting is our way of distributing power, yet the question of our influence remains.

    4. The power of the question
    Finally, it comes down to the question. Are we asking, “Where do we find alignment?” or are we asking, “Where do we see islands of energy? Where does the system want to go?” If that direction isn’t aligned with the higher purpose that brought us together, how can we change the boundaries or the environment so that the energy flows toward that higher purpose?

      Good. These are good lines of inquiry.

      The third one though is fraught. I don’t think the hosting team is necessarily representative of the “system” being worked with. This is where Dave’s work on distributed intelligence is very strong.

      I like the idea of islands and was thinking about them today, but these are the kinds of islands that must be lifted gently from the estuary, and even better, lifted by people within the system itself. This is why the distributed narrative and sense-making approaches matter. And why distributed harvesting is essential.

    Thanks, Chris, so much to learn here! I’m very grateful that you’re engaging so deeply with Dave Snowden’s work. There are many layers to navigate, and your willingness to sit in the tension of these ‘autumn king tides’ is incredibly valuable for the rest of us.
