It is such a gift to be able to „sit“ in her classroom, decades after Dana Meadows gave this brilliant lecture. Her work, her attitude and her wisdom are such an inspiration. It is a tragedy she isn‘t among us anymore. Fortunately, thanks to these videos and her great book „Thinking in Systems“ we can still interact with her work and her thinking.

Funny to see she describes what is nowadays commonplace with black box modelling. We have no clue what our KZfaq algorithm, chatgpt or other self-taught/artificially intelligent models do specifically. We can only know what went into the training set, not what it is that the models found. That's not too say the systems age is over though, it's just that humanity is no longer the only complex choice maker anymore.

She’s just great! Prof. Meadows shows our present education system simply doesn’t produce people with this level of acuity, intelligence, and cognitive clarity anymore… you think we aren’t getting dumber- we are. Look what we used to be like (watch any tertiary level lecture from the 1950-1980s and you’ll see the same thing: far smarter people talking far more competently) ❤

🎯 Key Takeaways for quick navigation: 00:00 🤖 *The lecture focuses on the philosophical aspects of system dynamics, emphasizing it as a philosophy for understanding complex systems.* 02:50 🧠 *System dynamics involves four crucial aspects: causal linkages, feedback loops, rates and levels, and structural behavioral relationships.* 05:23 ⚖️ *Causal linkages in system dynamics models aim to represent true causal relationships, distinguishing them from correlational relationships.* 08:15 🔄 *System dynamics models often include nonlinear relationships and account for delays in order to accurately capture the dynamic behavior of a system.* 18:09 ⭕ *Feedback loops are fundamental in system dynamics, with a basic feedback loop involving the state of the system, actions or decisions, and information flow.* 22:58 ➖ *Feedback loops can be positive or negative; negative loops counteract changes, while positive loops self-reinforce, leading to continuous growth or decline.* 28:06 💰 *Increasing oil prices lead to higher revenues for oil companies, enabling more investment in exploration.* 31:32 🔄 *The relationship between reserves, exploration cost, and price forms a positive feedback loop in the oil industry.* 32:10 🛢️ *Deregulating oil prices is discussed in Congress as a solution to maintain revenue for exploration, emphasizing the importance of the feedback loop.* 33:05 ⚖️ *System dynamics involve considering not only positive feedback loops but also negative loops, like the cost of exploration affecting the amount of oil discovered.* 35:09 🔄 *Systems in system dynamics are considered state-determined, meaning internal variables influence the system more than external factors.* 36:17 🔄 *Jay Forrester asserts that no human decision is made outside the context of a feedback loop, emphasizing the importance of understanding system dynamics in decision-making.* 38:47 🔄 *In feedback loops, there are levels (state variables) and rates (decisions/actions), forming the fundamental elements of system dynamics models.* 45:38 ⏳ *Delay symbols, while not used in this course, represent time delays in the impact of certain factors, such as the regulatory process affecting oil prices.* 49:01 📈 *Positive feedback loops tend to generate exponential growth, while negative feedback loops result in goal-seeking behavior over time in system dynamics.* Made with HARPA AI

Christians, believers, give us a black box modeling of the universe. The problem with Christians is truth is irrelevant, the end justifies the means. The number of lawyers indicted with Trump is the shame of Justice. Atheism doesn't explain anything, but the faithful don't have any standards for explanations. It cannot be moral or ethical to suggest there is a god. As if one should respect the suggestion, we all travel with one foot in fantasyland, using a fantasyland vocabulary. You know them by their works, so what does it tell you about those advocating prayer? Nothing fails like prayer in a children's hospital. Who advocates faith, when it is worthless if you can't move mountains using faith & verbal commands to landscape? What kind of person speaks of god as if we did not have a saying: God helps those helping themselves, because gods have a perfect record of doing nothing, outside of fiction. No wonder Freud wrote the antidote to Christianity is literacy.

This was known in 1977, how's it remotely possible that we are in do-do way over our heads in 2023. Is it the love of greed, in essence the love of money that will see us self annihilate?

It was known even earlier because LtG was published in 1972. but you are right, it's a good question. personally I believe a positive feedback between [wealth <=> political influence] has been a dominant feature. The more wealth you have, the more influence you exert over the decision-making process, which in turn generates more wealth. This has driven an acceleration of inequality as those who gain disproportionately more material benefit from the system gain greater power over the future direction of the system, which in turn yields further gains. Of course the delayed negative feedback loop which may limit this might be the feedback between [political/wealth inequality <=> social instability (dissatisfaction/lack of trust/civil violence/war)]. This could partly explain social revolution cycles. However environmental pressures will also increase social unrest.

Out of system dynamics came scenario planning. Shell oil used this tool in the 1980's to find oil.'They became really good at it. Scenario planning has now worked its way into many industries....I use this tool in harmony with critical reasoning every day...

I think/fear that self called elites just adopted war as a mean to reduce (regularly) world population, following the pig's festival example. But then, they seem to have skipped the part about the absolute erosion of oil and metal resources (and consequent societal collapse).

She did a great favor to humanity, however late. She is in essence the opposite of folks like Elon Musk and all the capitalists, economists, planners ( the infinite growth parasites ) of the earth. The book Limits To Growth, is a knockout, in the faces of mainstream economics, growth policies and all sorts of failed social engineering.

The thing that irks me is that in 2023 we are trashing our planet because we are ignorant to positive feedback loops. I'd suggest they don't make profit.
