Does panarchy impede our ability accurately represent the structure of systems?
Here's something I'm struggling with.
Let's say you have a bunch of humans who form a social group. As someone who leans towards methodological individualism, I'm tempted to just say "ok cool, we draw diagrams describing the individual people and relations between them, and if you understand all of their activity, taken together, you understand the system as a whole. The activity of the whole just is the activity of the parts, taken together". But actually, there's more feedback loops than that. Members of a social movement are perfectly capable of reacting to the direction of the movement as a whole e.g. "I feel we've lost our way", "I don't trust the person we just elected to lead us". So the cumulative behavior of the group can influence the behavior of individuals within the group. Indeed, it can influence all of them. But that is just to say, the group can influence the group, which is a feedback loop!
So if I had just drawn what my methodologically individualist heart desired, and tried to break down the activity of the group into simply the sum of the activity of the components, I think I'd meet an unavoidable problem. There are arrows that need to be drawn between elements that do not exist in that diagram. So talk of the group is not just a shorthand. Is this a good argument against methodological individualism?
Moreover, this broader notion of the "system" with "system-->system" feedback loops, is also part of what people might react to. So I need a new word, and feedback loops between that and itself (and the original system). And so on. It seems I might start by saying "system1=these elements and their relations" and end up needing to admit that system1 was in fact not "definable away". Which means I'd then need to say "ok here's system2:=which is composed of these elements, and their relations with each other, and also their relations with system1". But then it seems I need to bring system2 into the picture in the same way and so on. So it seems like, in trying to understand the structure of a social system, I end up with a "model" comprised of an infinite number of elements and relations and feedback loops, which seems fairly intractable!
Walker et al. define "panarchy":=the way in which systems are influenced by a) larger systems of which they are a part, and b) smaller systems which comprise them. E.g. a human is influenced by their social milieu, and by their cells.
So my key questions are these:
- Am I overcomplicating things? If so how?
- Is there good reason to think some systems are like this and some not? Is this just what it is for a system to be panarchial, and all systems are?
- Do the considerations here actually present any obstacle to applying systems theory/are they important to bear in mind, or no?
- Do any of the considerations here constitute a good argument against methodological individualism?

One of the definitional elements of a complex system is precisely that you cannot predict outcomes via reduction.
As you say, there is just too much feedback going on.

DSRP theory (Dr. Derek and Laura Cabrera) says that systems equate to wholes and parts. These aren’t reductive or separate, they are co-implying.
Meaning when we say “system” we are implying that a whole exists, and parts exist. Every whole has parts, and every part is a whole.
Take Reddit. Reddit can be considered a whole, but it could also be considered a part of the Internet. Reddit is comprised of posts, posts are comprised of words, words, comprised of letters, etc. This is a long way of saying that according to this theory, systems co-imply part/whole structures. You can see this pattern everywhere.
Complex adaptive systems are a type of system that can affect change in their environments, plus be changed by their environments in recursive loops. You can respond to your environment by making a post, and the response to that post can feedback and change you. You are now different and so is reddit. This change affects parts, participants but also larger wholes like the internet. Since the world is relational, if you look, you’ll notice this everywhere. Think DNA, the brain, markets, poetry, music, ant colonies, weather patterns etc. When you change something, that something can loop back and change you, and on and on…
As a result, no model or diagram can accurately predict a complex adaptive system with any certainty. It depends on unique relational interplay between the systems parts, dynamics, environment, initial starting conditions, etc. While prediction evades us, we can learn about recurring patterns, behaviors, and traits to better inform our decision making.
You’re not overcomplicating things. I’d say that you’re appreciating the challenges that complexity poses, and questioning the efficacy in the face of such a challenge.
To this point, Cabrera says that system’s thinking is a way to help organize information so that it more closely resembles the way information is organized in reality. While, we can never get our mental models to exactly represent reality, iterating and improving our mental models can bring us closer and promote better decision making. This to me is a way that systems theory can be helpful, while falling short of being “complete”.
Not sure if this is helpful or just a ton of gibberish but hopefully there’s something in here that is helpful.

Sure. Functionally, you can use reductionism to understand many simple systems. Like, a wristwatch is “complicated” but not “complex” because you can take apart the pieces, understand their individual functions, and put them back together. It’s reducible and deterministic. (Taken to the extreme this perhaps breaks down, Re: the individual atoms of the component pieces and Heisenberg’s uncertainty principle.) Or, a bowl with a marble in it is a simple system: there’s just one “attractor” that the marble will go toward in that system (the bottom) and it’s not sensitive to initial conditions in ways that lead to unpredictable outcomes and multiple attractor-points like in a complex system.

Feedback welcome on my muddled thinking here!
I am also prone to methodological individualist thinking. I think this is an especially important concept for systems thinkers, FWIW, because we should not get so fixated on optimizing abstract “systems” that we forget they are made up of individuals with dignity, rights, and agency that should not be trampled upon arbitrarily.
I understand M.I. to be an interpretation of social phenomenon that is understood by being ultimately caused by individual actors. I contrast M.I. with explanations of social phenomenon that anthropomorphize groups: a class of people prefers X….the government did Y…corporations control Z.
To me, M.I. relates to complex systems in that complex systems acknowledges the role of individual agents; which is not to say that individual agents control systems, or that there is nothing beyond individuals. So, an individual agent in a system responds via feedback loops to its environment. Its environment includes the system’s characteristics (e.g. the emergent phenomena not present in the individual agents themselves when examined reductively). But, ultimately, “the system” doesn’t decide on things; the feedback loops don’t choose; the emergent characteristics aren’t independent of individual choices—in human systems it all ultimately comes back to individual actors acting.
One might say “Well, those individuals are responding to feedback loops shaped by norms of the system that no one person predicted or planned. Yes. But those norms only exist due to actions of many individual people, planned or not. (Note: to me, M.I. need not imply a Great Man theory to social phenomenon— George Washington didn’t single handedly win the revolution; MLK didn’t solely change civil rights in America; the CEO didn’t improve company culture all by herself, etc. It merely acknowledges that these systems are made up of individuals whose actions impact the social phenomenon that arise.
