announcing The Necessary Tangle – a living evidence atlas of systems | cybernetics | complexity

I’ve been wanting for years to do a ‘better map’ of systems | complexity | cybernetics, having strongly criticised the Castellani ‘complexity map’ and seen some others – and been involved in the SCiO SysBoK where we tried to map key concepts, their necessary antecedents and dependent thingummies, people, meaning, and so on (- and always inspired by ‘rock family trees’ and the way it’s the constellation of influences and people around individual practitioners that actually makes the difference, as David Ing says).

So with the assistance of ChatGPT, and I’ve been building The Necessary Tangle – a living, evidence-backed atlas of systems | complexity | cybernetics.

It currently maps 411 public entries and 32 developed profiles from 93 registered sources.

The key difference from the usual family tree is that every line has to say what sort of relationship it represents: logical antecedent, historical precursor, documented influence, teaching, collaboration, practical use, and so on.

The eventual ambition to: trace the human as well as conceptual lineages; connect theory to practice; distinguish espoused intellectual genealogy from the clusters the evidence actually produces; and let categories emerge from the resulting network rather than deciding the schools in advance.

It’s very much a public alpha. Some areas are already quite deep; others are little more than markers saying ‘this belongs here’. I’m putting it out now precisely because corrections, missing connections, rival genealogies and ‘surely you can’t say that’ responses are part of building it.

AND I’m very happy to share, collaborate or whatever….

Epiplexity (epistemic complexity)

“Epiplexity (epistemic complexity) is a formal information-theoretic framework introduced by researchers at NYU and CMU to measure learnable structure for computationally bounded systems like neural networks. It fundamentally challenges classical Shannon entropy by accounting for observer limitations.”

“Core Framework Paradoxes Solved

  • Deterministic Functions: Explains how deterministic simulations generate new, learnable structural information for bounded observers.
  • Sequence Dependence: Accounts for data order and training curricula, which classical symmetric metrics ignore.
  • Inductive Biases: Focuses on the structural shortcuts internalized during training rather than pure distribution matching.”

42 | The Systemic Review- a publication of SCiO

Most public problems aren’t unsolved. They’re undiagnosed.

Because systemic problems demand systemic solutions.Read the papers

42 The Systemic Review applies systems principles to live problems in government, public services and civil society. We identify the structures, relationships and forces producing the outcomes we see – providing short, evidence-grounded analysis for people who commission and shape policy, and for anyone seeking to understand complex societal problems.

Design Horizon – An open library of emerging practices and provocations for tackling our world’s most wicked problems – Guerra (2026)

[I have to say, I’m laughing at myself. I made https://transduction.systems/ – The Necessary Tangle | A living evidence atlas of systems | cybernetics | complexity using ChatGPT (just like I made a series of ‘commissioning compasses’ at https://publicservicetransformation.org/tools/), and, just as my brother and sister-in-law chose brilliant, unique, rarely-used names for my niece and nephew, only to discover, you know, two children in the same year with the same name… they’re like Ford Cortinas… every arsheole has one! The zeitgeist and, as McLuhan would say, the media technology, has its own designs, doesn’t it? So there are now millions of compasses and living atlases, this one done by Ruth Guerra and Claude (evidently), each *somewhat* reflecting the personality of their creator and somewhat… something else.

This one is nice, conciser (36 hand-reviewed sources so far), and has some systems thinking stuff in it 🙂 ]

Design as a living compass.

Design Horizon is a free digital resource library for people creating within complexity. It was created by Ruth Guerra, a systemic designer, researcher, and founder of Phenomena Co-Design.
