A Philosophical Look at System Dynamics
https://www.youtube.com/watch?v=XL_lOoomRTA

Dartmouth College, Hanover, New Hampshire, Spring of 1977. In this lecture, Donella Meadows takes on a more philosophical concept. How can we bring ourselves to be aware of the assumptions we make as systems thinkers? She asserts that models are a set of assumptions. Donella Meadows defines some of these system dynamics assumptions (such as causal relationships and feedback loops) in this video.

(causal linkages, feedback loops, rates and levels, and structural
behavioral relationships)

An unregulated post-growth transition in the North can cause crises in the South: debt, inflation, unemployment. That’s the finding of a new paper by CUSP researchers Dario Leoni, Andrew Jackson and @ProfTimJackson. Their analysis from the PADME model reveal that financial transfers and global cooperation are essential to make it work internationally—ecological space isn’t enough.

EFU: When We Stop Merely Measuring Reality and Start Learning Its Language

There are moments when a new unit of measurement seems, at first glance, like a technical detail. Later, it turns out to be something much more important: a change in how we think. I believe EFU may be exactly that kind of shift. It is not just another number. It is a new language for describing the flows that sustain human civilization — material, energetic, ecological, and social.

The real importance of EFU is not only what it measures, but what it reveals. It invites us to stop seeing the world as a collection of isolated data points and start seeing it as a connected system of flows. Water, energy, materials, waste, agriculture, transport, and environmental pressure are not separate stories. They are chapters of the same larger story. EFU helps make that story visible.

A New Unit, Not Just a New Label

The most interesting thing about EFU is not the number itself, but the way of thinking it encourages. When we begin to look at a problem through EFU, we no longer see only statistics. We see relationships. We see dependencies. We see thresholds, bottlenecks, imbalances, and patterns of stress that are otherwise easy to miss.

That is why EFU matters. It does not merely describe the present. It helps us ask whether a system is stable, whether it is being overburdened, and whether it can remain viable over time. In that sense, EFU is not only a measuring tool. It is a tool for understanding resilience.

Why This Could Matter More Than It First Appears

Every major historical era has had its own dominant way of measuring reality. The industrial age centered on mass, energy, and power. The digital age elevated information, data, and connectivity. The next era may well revolve around flows, pressures, limits, and ecological coherence.

EFU fits naturally into that future. It suggests that the question is not merely “how much is there?” but also:

• How does it move?
• What system is it part of?
• What does it cost?
• How long can it continue?

That is a much deeper way of thinking. It is not just accounting. It is civilizational self-awareness.

The Future Vision: When Measurement Becomes Thoughtful

What makes EFU especially exciting is that it points beyond itself. If some of the most advanced ideas in modern physics suggest that spacetime, locality, and even causality may not be fundamental, but rather emergent from a deeper layer of reality, then we are already living in a world where our old intuitions may not be enough.

EFU belongs to that broader intellectual horizon. It does not need to claim that it is “new physics.” But it can certainly be understood as a step toward a new kind of structured thinking: a way of measuring reality that is more aligned with systems, thresholds, and hidden dependencies.

In that future, artificial intelligence could become a particularly powerful partner. Not because it merely computes faster, but because it may detect patterns that are too complex for human intuition alone. If EFU is paired with AI-driven symbolic reasoning, we may not just analyze data more efficiently — we may discover new kinds of relationships:

• hidden ratios,
• tipping points,
• structural imbalances,
• and system-level laws that are difficult to express in ordinary terms.

The Intuitive Advantage

One of the strongest qualities of EFU may be its intuitive power. A good unit of measurement does not oversimplify reality. It organizes it. It makes complexity legible without distorting it.

That is especially valuable in areas like:

• water management,
• agriculture,
• energy systems,
• waste treatment,
• urban planning,
• and environmental policy.

In these fields, raw numbers often fail to communicate what is really happening. EFU can help bridge that gap. It can create a shared framework in which experts, decision-makers, and ordinary citizens can discuss the same problem in the same conceptual language.

That is a rare and valuable thing. A unit that improves understanding is more than a unit. It becomes a bridge.

A Small Concept With a Large Horizon

EFU may still be an emerging idea. It may need refinement, testing, and better formalization. That is not a weakness. In fact, it is often the mark of a genuinely important idea. The most transformative concepts rarely arrive in finished form. They begin as a direction, a hunch, an intuition that something essential is missing.

And perhaps that is what EFU is really pointing to: a civilization that no longer measures only what it extracts, consumes, or produces, but also what it sustains, balances, and preserves.

If that is true, then EFU is not a side project. It is a possible step toward a new intellectual culture — one that understands that the future will not be shaped only by growth, but by balance.

Dieser etwas längere, aber dafür inhaltlich umso reichhaltigere Artikel aus #Noema zieht Parallelen von Plantagen, #Massentierhaltung und der autogerechten top-down #Stadtplanung zur monopolistischen Struktur des Internets und schlägt analog zum #Rewilding von Naturgebieten ein Rewilding des Internets vor.

"The story of German scientific forestry transmits a timeless truth: When we simplify complex systems, we destroy them, and the devastating consequences sometimes aren’t obvious until it’s too late. …

Internet infrastructure is a degraded ecosystem, but it’s also a built environment, like a city. Its unpredictability makes it generative, worthwhile and deeply human. In 1961, #JaneJacobs, an American-Canadian activist and author of “The Death and Life of Great American Cities,” argued that mixed-use neighborhoods were safer, happier, more prosperous, and more livable than the sterile, highly controlling designs of urban planners like New York’s #RobertMoses."

"Technologists are great at incremental fixes, but to regenerate entire habitats, we need to learn from ecologists who take a whole-systems view. Ecologists also know how to keep going when others first ignore you and then say it’s too late, how to mobilize and work collectively, and how to build pockets of diversity and resilience that will outlast them, creating possibilities for an abundant future they can imagine but never control. We don’t need to repair the internet’s infrastructure. We need to rewild it."

📊 Rethinking inventory strategy — new system dynamics research challenges retail norms.

A recent study shows that introducing a competing product earlier during an existing product’s decline phase can lead to higher long-term revenue. 🤯

Key insights for retail leaders:
🛒 Inventory decisions must model real substitution behavior
🔁 Early introductions can phase out old products more profitably
🧮 Demand forecasting should include stockout effects
📦 Safety stock planning and shorter review cycles reduce lost sales
🧠 Dynamic, not static, strategies win in FMCG and tech retail

This is a must-read for anyone managing product portfolios, especially in fast-moving markets where demand shifts fast and substitution patterns aren't predictable.

Maybe in my #systemdynamics bubble someone can answer this question regarding #elasticity in a continuous-time dynamical systems context (i.e., it is a factor scaling fractional rates)?

Why is this (very natural) momentum-related formulation not more widespread in models?

Jay Forrester (at 21:00) about #systemdynamics and why governments around the world are not able to stop #climatechange:

"a deep understanding of these issues would make a very major change in the world but that deep understanding [..] has to include a public understanding because you cannot expect these changes to come from the top of a corporation or the top of a government. People in [..] System Dynamics as well as other approaches to policy design are always talking about convincing decision makers. There are no such people [..] When it comes to the big issues if a policy in government or a corporation is going in this direction and that's a governmental policy and you'd like to push it a little bit one way or the other then you can persuade and you can have lobbyists and you can bribe a few people and you can push it a little bit but if the real goal is to reverse it totally there is no government that's capable doing that unless there is a public support and so [..] it has to come up from the Grassroots [..] to be able to deal with the big issues that put the long-term ahead of the short term which is one of the main things [we need to do]"

John Scales Avery (1933-2024) was an American theoretical chemist. In his book "Civilization's Crisis" he argues that civilization as a whole faces a set of linked challenges. #ClimateChange is caused by consumption of non-renewable #FossilFuels but it is just one aspect of a bigger crisis. Other aspects are #Deforestation, #OceanAcidification, #NuclearWaste and #pollution in general. #ResourceDepletion and #VanishingResources in combination with #OverPopulation will eventually lead to a #collapse of #civilization in this century according to #systemdynamics and classic #limitstogrowth models. The turning point is #PeakOil or the #HubbertPeak which we are reaching now.

Prof Steve Keen recommended this short climate film to the seminars. So glad he did - I echo his recommendation! Strong shared themes with the climate elements of his critique of mainstream econ, incl. feedback loops, tipping points, and complex systems. And yet, accessible! An important film.

Whew! Steve Keen's legacy seminar was a real treat today! Watching him building data-analysis models on-the-fly in his own systems dynamics & double-entry accounting program - Ravel - is poetry in motion!

He mentioned recently that he now has a promotions assistant who helps maintain his social media accounts; today I asked him if he and/or the assistant could set up an account on Mastodon. He said, "That's a good idea!" So, fingers crossed...

My new article is about opportunity and #hope, which people need in order for societies and economies to work.

The way out of a downward spiral isn’t to fuel anger by taking away the remaining opportunities and flexibility that people have or perceive they have. The way out is to invest in creating better opportunities with real and significant and lasting returns for people and thus, eventually, for societies.

🧩 Miscellaneous bits if you’ve made it this far is that I studied molecular biology, biochemistry & mathematics but dropped out to become a systems administrator, a professional Linux developer, then a hacker for hire.
🔐 I still hack by accident (because hacksidents happen), and nobody should have to be the coauthor/coeditor of the International Standards on how to do Vulnerability Disclosure to get an organization’s attention.

🙄 Despite my entire career being technical, when my company tried for venture capital funding to build something cool, we were met with sexism & lack of imagination & I was hilariously asked more than once if I had a technical cofounder.
It’s cool, joke’s on them. We’re #profitable and growing.

🛑Ending abruptly is on brand for me as a neuroatypical person, so I’ll leave you with this thought:
🐈 I named my 17 year old cat Scapy (rhymes with happy) after the Python tool of the same name. Because he is dumb & fuzzy.

100th post, as fine a time as any to do the traditional #introduction before nobody on #mastodon does them anymore.
I’m a #hacker , a parent, a founder & CEO, government advisory board member, cat food servant, defender and participant in democracy, & an arm wrestling and karaoke enthusiast — not necessarily at the same time, but not opposed to trying it all at once either.
Carpe brachium karaoke as they say. 💪🏼🎤
Here we go. Get a snack & some water, this is long. 🍪 🥛
My professional passions include #SystemDynamics & #security with my #focus on helping organizations & governments develop healthy sustainable #VulnerabilityDisclosure programs that may end up growing into a #BugBounty program, or helping existing programs mature & evolve.

🌺I founded & run https://www.Lutasecurity.com & we employ dozens of people, mostly in the US, to help some of our customers manage their #VDPs and #BugBounties as internally-placed personnel.

I helped launch #HackThePentagon in 2016, which was the first bug bounty of the US government & the first time it was legal to hack the USG.

This was after I created Microsoft’s first bug bounty programs in 2013, paying out the most at the time for brand new exploitation techniques, which would later lead to me directly helping the US renegotiate the #Wassenaar Arrangement to clarify “intrusion software” and “intrusion software technology” export control exemptions to more easily allow for hassle-free exchange of 0day & malware samples across borders for vulnerability disclosure & incident response.
🛠️💻 🛠️💻 🛠️💻 🛠️💻
I also started two vulnerability research programs, Symantec Vulnerability Research & Microsoft Vulnerability Research. The latter was also the first formal major vendor multiparty #SupplyChain vulnerability coordination & disclosure program.

🎙️Fun fact: Despite mainstream media lip service about getting diverse voices on TV, and my extensive direct experience in US domestic & foreign cyber policy & norm-setting, I have *never* been invited to be on broadcast news to talk about it. Not one time. But there are the same dudes with none of my experience showing up on TV all the time.

👩🏻‍⚖️ Speaking of gender equity, I was the lead plaintiff in the attempted class action gender pay and promotion discrimination lawsuit against Microsoft.
💵💪🏼 https://www.theverge.com/22331972/pay-equity-now-pledge-katie-moussouris-microsoft-lawsuit
When it failed to get class certified due to some legal gotchas, NOT because of lack of data and evidence, I decided to drop my case and founded https://www.payequitynowfoundation.org/blog & created
https://www.manglonalab.org/ to fight for #PayEquity in our lifetime.

🌸Another fun fact: I’m asked about the gender stuff way more often than any of my professional work or national security work. I view this as The Lady Tax & I’m all paid up thanks.
🙅🏻‍♀️Don’t ask me about how to attract more diverse candidates, don’t ask me to mentor your mentee, and don’t ask me for any more free labor. Don’t ask any historically marginalized people to do free labor, especially to solve your diversity puzzle.
👏🏼I highly recommend https://blacktechpipeline.com/ if you are serious about not just hiring but welcoming more black workers into your company. There are specialty recruiters out there for you to pay, so don’t ask every woman or person of color you know to help you with that unless they are being paid to do it.

Recent work presented at the Eating Disorders Research Society #EDRS2022:

We built a stock/flow #systemdynamics model to understand the structural processes that maintain low #mentalhealth service use among men with #eatingdisorders.

Intervention tests: We found that primary prevention had the greatest impact on reducing ED prevalence, while an awareness campaign increased #mentalhealth service use. However, complex system behavior (feedback loops, adaptations) limited their impact.

#introduction

I'm Stephanie, an operational #riskmanagement consultant who worked in IT risk regulation in finance. I studied #journalism initially, then #infosec before focusing on risk.

I'm interested in #climate and #ai risk, #systemdynamics, low-level #programming, #markets, and explaining complex topics in simple ways. In my spare time, I enjoy #songwriting, #poems, #sff, and visual #art. I love #tea, #chocolate, and #slowtravel.

Happy to be here and looking forward to conversations!
