In 1999, Frederic Vester published a report to the Club of Rome named “The Art of Interconnected Thinking”. The main focus of the book is about understanding complex systems, and how a number of interconnected models, what he called the Sensitivity Model, can help us do so. The Sensitivity Model is an IT-based approach, today in the ownership of Malik Management. While other IT-based approaches try to connect some 200+ variables into a database, Vester is frugal in comparison, with 10-20 variables. The advantage of his approach over the more mathematical siblings is the acceptance and use of fuzziness. We simply cannot expect to be able to get a total picture of our system with sharply differentiated concepts and mathematical variables, so stop trying to do it anyway. The consequence is: we better accept that whatever model we use, it will be incomplete and partially wrong. It would be foolish to attempt something that is 100% correct. Therefore, a more realistic ambition is to create a model which is relevant to the pragmatical perspective of the beholder, and is sufficiently apt to produce this relevance.

Humans and viruses have been coevolving for millennia. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2, the virus that causes COVID-19) has been particularly successful in evading our evolved defenses. The outcome has been tragic—across the globe, millions have been sickened and hundreds of thousands have died. Moreover, the quarantine has radically changed the structure of our lives, with devastating social and economic consequences that are likely to unfold for years. An evolutionary perspective can help us understand the progression and consequences of the pandemic. Here, a diverse group of scientists, with expertise from evolutionary medicine to cultural evolution, provide insights about the pandemic and its aftermath. At the most granular level, we consider how viruses might affect social behavior, and how quarantine, ironically, could make us susceptible to other maladies, due to a lack of microbial exposure. At the psychological level, we describe the ways in which the pandemic can affect mating behavior, cooperation (or the lack thereof), and gender norms, and how we can use disgust to better activate native “behavioral immunity” to combat disease spread. At the cultural level, we describe shifting cultural norms and how we might harness them to better combat disease and the negative social consequences of the pandemic. These insights can be used to craft solutions to problems produced by the pandemic and to lay the groundwork for a scientific agenda to capture and understand what has become, in effect, a worldwide social experiment.

Nobel prize recipient Daniel Kahneman distinguishes two different thinking pathways according to whether we think hotly, which is quickly and automatically, or coldly, that is slowly and reflexively:
• With the system 1 thinking process, the brain forms thoughts that are fast, automatic, stereotypical, emotional and often unconscious – think of the first thing that comes to mind when you are presented with an object, an idea or a situation. • With the system 2 thinking process, the brain calculates wilfully a response by directing attention to the situation, figuring it out and formulating a deliberate response.
Max Boisot – The City as a Complex Adaptive System
27 Sep 2020
The first seminar in this Series took place on Thursday 18 November 2010 at the Lighthouse. The ATLAS Collaboration will conduct experiments at the very edge of science, using one of four detectors located on the Large Hadron Collider (LHC) at CERN. The Collaboration consists of over 3000 scientists working in over 174 research institutes and universities located in 38 countries around the globe. In such a complex and spatially extended network (what we would today call a complex adaptive system) how do the knowledge flows allow the creation of one of the most sophisticated technological objects ever built? Drawing on a conceptual framework, the Information-Space or I-Space, Max Boisot described and tried to make sense of the ATLAS collaboration’s culture. He explored the lessons that the management of globally distributed ‘big science’ projects such as the ATLAS collaboration hold for other complex adaptive systems such as cities.

This course provides an introduction to Transition Design, a new approach to seeding positive, systems-level change and catalysing the transition of entire societies toward more sustainable long-term futures.
A game is another name for a conversation. When people play together, or talk together, they are creating a game which lives through their participation. The ‘playing’ is the dynamic which maintains the boundary of the game, just as the internal and external processes of a cell maintain its boundary with its environment. Games are like cells.
Like all whole systems, there is a meta-system which maintains the integrity of the whole. Games have rules, and rules are determined by the meta-system. The game lives as a viable entity because of the dynamic relationship between the rules of the game and the play. The rules might be thought of as a meta-game.
The relationship between the meta-game and the game is very much like the relationship between the shifts of entropy in play, and the shifts of maximum entropy of possible moves. Maximum entropy determines the maximum amount of disorder available to the game – in effect this relates to the maximum moves allowed by the rules at any point. The entropy of play relates to the constraints (rules) imposed by the metasystem. Both the rules and the play can evolve.
This is rather like the game “Nomic”, where moves in the game change the rules.
There is an interesting question as to when a game comes to an end: the constraints produced by the meta-system mean that the entropy of play is zero.
If a conversation or dialogue is a game, then they can come to a pause, but somehow the “talk” goes on in other ways. The pause in a game is also the result of the entropy of play hitting zero – at least within a particular frame of play. The rules of a game can enforce this pausing-zeroing – like the games and sets in tennis, or timed halves in football. Their purpose is to impose pattern on the sequence of events, so as to set up the conditions for an eventual ending.
In education, summative assessment does the same thing: it sets up the conditions for an ending of the game. Appeals, mitigations, etc, open the thing up again, but this too is demarcated to create a pattern which is designed to come to an end.
Formative assessment, by contrast, is the actual “playing” of the game.
One of NECSI’s ongoing projects is to further the understanding, dissemination, and advancement of CSS by capturing key CSS concepts in visual models. Below are a few examples of this work in progress.
About the Visual Models
Generalized diagrammatic models present an abstract high-level view visualizing the fundamental phenomenon common to complexity studies. Ultimately these models will be expanded to show the connections between concepts and be linked to examples of how these general concepts are manifest in disparate, specialized areas of complexity research. Because CSS is a relatively new and transdisciplinary field, an effort to define its current state will benefit from an integration of knowledge across domains into a compact generalized form – most efficiently represented by diagrammatic models.
We’re delighted to announce the start of a new, online seminar series ‘Making connections- brains and other complex systems’, which is not specifically a CNN activity but we believe will be of interest to many on this list.
The series will cover brain networks and other complex systems, and aims to bring together researchers from a range of fields, including systems neuroscience, psychiatry, genomics, computer science, machine learning and physics.
We are starting off with a fantastic line up of speakers particularly focused on the brain- see the schedule below. Talks will be held at 3pm online on alternate Tuesdays, and titles/abstracts and a link to the meeting will be circulated nearer the time.
Tues 17th November 2020- Dr Conor Liston Tues 1st December 2020- Prof Dani Bassett Tues 15th December 2020- Dr Aaron Alexander-Bloch Tues 12th January 2021- Prof Olaf Sporns
Arguably, almost all truly intriguing systems are ones that are far away from equilibrium — such as stars, planetary atmospheres, and even digital circuits. But, until now, systems far from thermal equilibrium couldn’t be analyzed with conventional thermodynamics and statistical physics.
When physicists first explored thermodynamics and statistical physics during the 1800s, and through the 1900s, they focused on analyzing physical systems that are at or near equilibrium. Conventional thermodynamics and statistical physics have also focused on macroscopic systems, which contain few, if any, explicitly distinguished subsystems.
In a paper published in the journal Physical Review Letters, SFI Professor David Wolpert presents a new hybrid formalism to overcome all of these limitations.
Fortunately, at the turn of the millennium, “a formalism now known as nonequilibrium statistical physics was developed,” says Wolpert. “It applies to systems that are arbitrarily far away from equilibrium and of any size.”
Nonequilibrium statistical physics is so powerful that it has resolved one of the deepest mysteries about the nature of time: how does entropy evolve within an intermediate regime? This is the space between the macroscopic world, where the second law of thermodynamics tells us that it must always increase, and the microscopic world where it can’t ever change.
We now know it’s only the expected entropy of a system that can’t decrease with time. “There’s always a non-zero probability that any particular sample of the dynamics of a system will result in decreasing entropy — and the probability of shrinking entropy grows as the system gets smaller,” he says.
At the same time that this revolution in statistical physics was occurring, major advances involving so-called graphical models were being made within the machine learning community.
In particular, the formalism of Bayesian networks was developed, which provides a method to specify systems with many subsystems that interact probabilistically with each other. Bayes nets can be used to formally describe the synchronous evolution of the elements of a digital circuit — fully accounting for noise within that evolution.
Wolpert combined these advances into a hybrid formalism, which is allowing him to explore thermodynamics of off-equilibrium systems that have many explicitly distinguished subsystems coevolving according to a Bayes net.
As an example of the power of this new formalism, Wolpert derived results showing the relationship between three quantities of interest in studying nanoscale systems like biological cells: the statistical precision of any arbitrarily defined current within the subsystem (such as the probabilities that the currents differ from their average values), the heat generated by running the overall Bayes net composed of those subsystems, and the graphical structure of that Bayes net.
“Now we can start to analyze how the thermodynamics of systems ranging from cells to digital circuits depend on the network structures connecting the subsystems of those systems,” says Wolpert.
Michael: So Brian, it’s a pleasure to meet you here amidst the complexity.
Brian: Thank you. Delighted to be here.
Michael: I think I’d like to take this conversation in three parts. One, kind of looking back at the history of the development of complexity economics and the argument for it that you’ve put forward in a book and in numerous papers. And then to dig into the actual mechanisms involved and to explore some of the ideas that you get into in The Nature of Technology.
Michael: And then you have a 2017 article for McKinsey that I thought was really fascinating in terms of looking forward into the shape that the new economics systems are taking. So if that sounds good to you…
Brian: It sounds great.
Michael: Awesome. So you were there at the beginning of the Santa Fe Institute’s articulation of complexity economics. And I’m curious, what brought that together in the first place, and what got you involved and what you saw, you and the other people involved saw as the need that you were addressing at the time.
Brian: Right. In 1987, there was a famous meeting held here at the Santa Fe Institute in September, and it was decided that about 10 scientists and 10 economists would be brought together by Phil Anderson, who’s a Nobel prize winning physicist, David Pines, very eminent physicist, and Kenneth Arrow, Nobel economist, and they brought 10 of us together. The science group included luminaries like John Holland, very famous these days, David Ruelle mathematician, and Stu Kauffman and others. And on the economics side you had Larry Summers who went on to be president of Harvard, Tom Sargent, who in the future would get a Nobel in economics, and others including myself.
What can public services do, in the time of COVID, to nurture a better future?
Join us and we will live it out together!
In the heart of the first lockdown, I set up ‘a learning community to build back better in the days after’.
A community which swelled to 120 people in the UK and internationally who really care about the role public services play in the lives of people and communities.
Our hundred-day journey went from confronting the true complexity of the challenges we face, through exploring possible futures – depressing! And on to looking at the possible futures we *liked* and that might make a difference.
We ended in August, with our own manifesto – about what
*we* needed to be and do to contribute to that better future.
The challenges continue. This is not grand policy or shoulda-would-coulda. This is about a small group of concerned people working out how to make a difference.
Introducing Enigma – The Little Black Box. Basell Complexity Meetup
Description
In the last months I have created a little computer game which you can use to learn, and teach, about how decisions become fundamentally different when things become complex. It is based on a thought experiment by Heinz von Foerster, the Non-Trivial-Machine. In this meetup we will play the game, reflect our experiences, and explore the history of the concept and how we can use it to convince others to stop treating complex issues as if they were trivial.Time
This online calculator computes Shannon entropy for a given event probability table and for a given messageperson_outlineTimurschedule7 years ago
In information theory, entropy is a measure of the uncertainty in a random variable. In this context, the term usually refers to the Shannon entropy, which quantifies the expected value of the message’s information. Claude E. Shannon introduced the formula for entropy in his 1948 paper “A Mathematical Theory of Communication.”
Minus is used because for values less than 1, and logarithm is negative. However, since
,
formula can be expressed as
Expression is also called an uncertainty or surprise, the lower the probability , i.e. → 0, the higher the uncertainty or the potential surprise, i.e. → ∞, for the outcome .
In this case, the formula expresses the mathematical expectation of uncertainty, which is why information entropy and information uncertainty can be used interchangeably.
