In my personal experience it really depend on what you are trying to build but most of the time it ends in the party/collective/space expelling the person from it. What can make this process less dramatic and damaging is the organizational culture you have in the space or the party. For example, in the organization that i´m part of when we reunite, all men are required to help in some domestic(cleaning, cooking or preparing the room for the meeting) and organizing(taking notes on the meeting/discussion, being the mediator of the meeting/discussion[1] and so on) task because we have perceived that this is a way to make the woman in the organization participate more actively in the discussions and we as an organization want them to participate more on these discussions. So we have a culture of doing that and for some time it has been a self-reinforcing thing. So if i stopped doing it, my comrades would call my attention to it and if i really took a stand against it, i would probably be kicked out of the organization. My hypothetical exit would galvanize no one because we have been doing this specific thing for a long time and everybody agrees that we should keep doing it.

In short: I don´t have a definitive answer but a good guess would be organizational culture. We, humans are very social species and take a lot of cues from the people around us and if we are able to create a good organizational culture in a space/party/collective people will mostly follow it. That said,it is hard to create a good organizational culture, people in the org or the space really need to want to make it happen but once it is create it is easier(or less harder) to keep.

I had basically this exactly same question about how can open source software be safe if just anyone can make it. It was basically the same...sure, you can't totally trust that people are vetting FOSS for malware..but can you trust big companies to NOT put malware and Spyware in our software? I sure as hell don't. Seems to be a Good analogy when discussing this type of thing.

Are there examples of stable horizontal power structures beyond ~1000 people?

Over the past years, reading more about the dark triad/quadriad, I am becoming more and more convinced that authoritarianism is the political expression of narcissism and that it is 100% of the explanation, that there is nothing more to it. Want to fight authoritarianism? Stop narcissist. It is not a matter of ideology, of left or right, of reformist vs revolutionary, it is just a matter of psychological profile. Stop the narcissist, that's all.

How do we build systems that are resilient to sabotage without falling into authoritarian logic?

I had a eye-opening moment with this videp, whose title ("Can 100 people self-organize without a leader") is actually misleading, as it (IMHO) failed to demonstrate what it wanted to test, but demonstrated something much more interesting. The task given to 100 people was too simple to require multiple people (a "hack" they forbade has shown that one person was enough to do the full task) yet, a hierarchy "naturally" emerged. Even though the sample population is biased towards people who would not be very hierarchical.

My main takeaway was that an organization that does not want a hierarchy does not only need to make it possible to self-organize, but needs to actively "weed out" hierarchies. That's hard, I don't know of any examples of it.

Exile and public shaming

How do you enforce exile and ensure that it is just? Because any cultural majority is going to pick on a minority even and especially without any distant government. The history of progress has been using a distant government (that can be impartial to local prejudice) to force majorities to accept minorities.

Eisenhower sending the 101st Airborne to protect black children is the only reason Arkansas desegregated.

And bad actors do not care about public shaming.

Bad actors are going to build their vertical power structures whether you like it or not. This is the challenge liberals are posing to anarchists: if you are unwilling to build your own vertical power structure then how do you stop the bad actors from building theirs and then using it as a cudgel against you?

Exile and public shaming are tools that only work against bad actors as individuals. They do not work when the bad actors team up and form a critical mass.

In the distant past, anarchism worked because everyone knew each other and bad actors had nowhere to hide to build their power structures and grow in strength. The agricultural revolution changed all this because of food storage and the potential for an outside group to attack and steal the food. People formed power structures and developed the first militaries in order to defend their granaries and this led to the growth of large cities where people no longer had the ability to know everyone.

Militaries also showed the power of hierarchies. Making decisions by consensus is slow. A military with a formal power structure has a huge advantage in combat against an unstructured tribe of warriors. This was proven again and again as the empires of the past conquered their neighbours.

But I digress. A large city where it’s impossible to know everyone is a huge problem for anarchists who want to prevent bad actors from forming a vertical power structure and taking over. There simply is no known social tool which can combat against the formation of conspiracies and elites within a large society.

I love it when people start asking the right questions. I think the absolute mess of responses just goes to show that this is an avenue of discussion that hasn't been pursued nearly enough in leftist circles.

We've interacted before - you may remember my comments on an earlier post of yours. I am generally of the position that narcissism lies at the core of all of the issues that anarchism is fundamentally trying to solve. If we can solve the issue of narcissism in society, then everything else more or less falls into place (though there are a lot of misconception about what is and is not hierarchy that gets in the way of seeing that for a lot of people, apparently - I'll try to address some of that).

What if we started seriously discussing tactics for dealing with domination-seeking behavior?

Since we can reduce our political/social problems down to this particular psychological problem (or at least I claim that we can, more or less), then we can try to understand hoe we might address those political/social problems by understanding how one addresses this psychological problem. Unfortunately, we immediately run into a bit of a trouble. There is no known effective treatment for this personality type/disorder. When we consider that we're talking about trying to change a person's personality, this sort of make sense, and it make additional sense when we consider that impaired empathy generally shows up on a brain scan as a sort of brain damage. In other words, our options are severely limited at the individual level. We also know that this personality type is extremely stable over the lifetime of the individual.

There are lots of things we might be able to argue from that position, but one point that I really want to highlight is that we cannot expect that we can make this problem go away simply by changing the material or social conditions of these people. Even a dedicated therapy effort doesn't really work. While we can largely prevent the creation of these individuals in the first place if we were to create the right social/cultural environment (most are made as infants and children by a variety of bad parenting practices), we cannot completely prevent them from occurring (some are simply born this way - about 1% of the population as I had said before). As such, the solution to this problem isn't going to be a simple change in initial conditions, but rather an ongoing process that is baked into the fabric of society itself.

Let me touch on the issue of how we went from a bunch of societies that existed for millions of years while reliably and robustly preventing these people from gaining power and making a mess of things to a society that is basically run exclusively by these people and seems designed to empower them. As you know but others may not yet be aware, I have a hypothesis about how hierarchical civilization came to be. What's important to observe about this narrative is that the peaceful egalitarian societies did not voluntarily become hierarchical. They were coerced/conquered by hierarchical societies that formed from the aggregation of their exiles. This story of hierarchical societies devouring egalitarian ones via conquest and subjugation then repeats itself over and over again throughout history. A question for the room: Is there any documented instance of an egalitarian anarchist society voluntarily reforming itself to become hierarchical?

My basis for anarchism is fundamentally founded in this perspective that narcissism is the root problem to address. IMO, the indigenous people largely did a good job - they just made the mistake of externalizing their narcissism problems, and then the additional mistake of failing to prepare for the consequences of that decision. We just need to learn from their mistakes, and do what they did not: In addition to aggressively policing the narcissists that emerge from within, we need to account and prepare for the external threat represented by narcissistic individuals that exist outside of our society. Even a society that solves the exile problem for itself will still have to deal with the exile problem from others, and that generally means maintaining a strong military or otherwise maintaining some mechanism for defending itself against organized threats from hierarchical societies.

What mechanisms help us identify and isolate that kind of behavior without reproducing the same old coercive structures?

Identifying these bad behaviors is both easy and hard. If you know what to look for, it's really easy. If you don't, you're liable to fall for their manipulation. Simply learning about the various manipulative behaviors that narcissists engage in is the conceptually most straight-forward way to address this problem, and it is certainly effective. There are other ways, though. One thing that I've noticed is that narcissists will pretty reliably violate the rules of epistemologically sound argumentation whenever they start to try something funny. Simply educating people about logic (and logical fallacies) and the burden of proof would go a long way toward making them resilient to narcissistic manipulation. If we also teach people to take such violations very seriously, rather than just dismissing it with a simple "everyone is entitled to their own opinion", we would catch a lot of bullshit very early and stop a lot of narcissistic machination before it has a chance to gain any real traction. If you think about it, tolerance of unsound argumentation is a necessary condition for a society to be vulnerable to non-violent manipulation from bad actors of any sort.

How do we build systems that are resilient to sabotage without falling into authoritarian logic?

I'm seeing a lot of people in the comments conflating centralization with hierarchy, and vice-versa, and this is a big problem. I want to make something very clear: Centralization does NOT imply hierarchy. This is very important to understand, as discarding the useful tool that is centralization out of fear of creating the horrible monster that is hierarchy will cripple our ability to achieve anything at all. But what is centralization? What is hierarchy? Why do people conflate the two?

Centralization is simply what happens when coordination or decision-making is delegated to a subset of the group. These coordinators or decision-makers take on apparently central roles because everybody needs the information/instruction that they provide in order to avoid doing redundant or pointless work. Centralization is desirable, because it means that people can specialize. Not everyone has to be involved in every process. Decisions can be made by those who are most qualified to make them, and everybody else can get on with their work without being interrupted about every little detail.

Hierarchy is what you get when you define an up-and-down axis of power. Some people are above others. Some people are below others. The people above have the power/authority to coerce the people below. Subordination is a crime that is basically defined as an individual defying the directives of an individual above them in the hierarchy. The existence of hierarchy does not strictly depend upon the existence of a particular social or governance structure within a group.

That said, hierarchies naturally tend to concentrate decision-making power in the hands of a few, and that's why hierarchy always seems to imply centralization in practice. It's hard to find examples of centralization that do not come with the trappings of hierarchy and coercion - you basically have to study the inner-workings of some worker-owned co-ops to find good examples. Combined with the fact that coercion is a concept that isn't part of common discourse (though I think that is starting to change), and it becomes easier to see why people might struggle to separate the two concepts.

We can have all of the benefits of centralized coordination without any of the drawbacks of hierarchy. We just need to establish a binding social contract that outlaws coercion, and aggressively enforce it. With these tools in hand, building public institutions or even a powerful military capable of rivaling modern civilization's best is all comfortably within the realm of possibility.

Might makes right is always the problem, whether you're talking about anarchy, or hierarchy, or some kind of distributed system - some actor will use force to inflict harm for their own benefit (in contrast to inflicting harm to defend others). I believe the study of human history tells us that this always happens, it is not preventable. So the question becomes, how do we build systems that can protect people from harm without concentrating power that may itself be abused?

• Expecting everyone to protect themselves is not a viable option. That way lies barbarism, where the weak are left to perish.
• I'm very open to ideas about resisting force with something other than equivalent force, but I'm not sure what that would actually look like in practice. What do you do when the bandits show up in town and start shooting and looting, other than shoot back?

If you diffuse power horizontally, there is no vacuum to fill. There’s just shared responsibility.

I'll just point out, this was the original concept behind the US Constitution. Whether it's worked as intended is... debatable.

I have a bit of an inverted perspective. All anti-social behaviors aside: can Anarchists build and maintain public infrastructure?

I like public utilities. If an anarchist commune can keep a wastewater treatment plant running and even expand sewerage to those without it, I am all for it. If the public drinking water systems can be maintained and uncontaminated that's a win in my book.

But practically speaking some functions of the state do serve the public, and I find that acceptable.

How do horizontal power structures handle problems of global scale? The COVID pandemic and how people behaved and created consequences for others comes to mind. I'm not sure if any of the tactics you mention would work. You can't shame people who think they're doing the right thing, can't exile them without a power structure that can use force on them, they have no leadership to revoke, and I'm not sure how distributed decision making would apply.

Another idea on that scale might be best exemplified by climate change (or pfas etc). Do horizontal power structures mean most people could ignore how they're impacting others negatively? If not, how would that be handled on a global scale?

If anybody is going to answer, I'd appreciate it greatly if the answer did not compare how much worse vertical systems are for these problems. If you can give me a novel idea about this, I'd appreciate it.

Pre-civilized societies didn’t let power-hungry individuals take over.

Pre-civilized societies were small.

The real question isn't whether bad actors exist. It's how we choose to deal with them. Do we build systems that make it harder for them to dominate others, or ones that practically roll out the red carpet?

This seems like a misunderstanding to me. The people don't build systems. The people are subjected to systems built by dominating bad actors.

I think it's rather simple, honestly. I like the ideas of anarchism, it sounds good in theory, but has already proven to be impossible

Humans started without governments or societies. We were anarchist already, and moved on to having societies and governments not just because of bad actors but many, many, many, many reasons. Whatever system out there that works the best is likely a monstrous hybrid system of many schools of thought, and likely needs to be fluid and changeable to work
