Reading through all 48 entries with the comparison lens, three structural observations emerge before any specific edits.

The unavoidable concreteness gap. The World Dynamics column has operational definitions (people/year, units of capital, square kilometers, satisfaction units). The Psychodynamics column has metaphorical extensions (intellectual and emotional energy, psychic population, unabsorbed complexes). This is not a deficiency in the 1971 text — it reflects that Forrester's system dynamics is built on measurable stocks and flows, and the psychological domain doesn't admit those measurements. But it produces an asymmetry that affects readability: a reader hits "people/year" once and moves on; "intellectual and emotional energy invested in long-term activities" requires unpacking every time it appears, which it does in roughly fifteen entries. From a general-systems-theory perspective, this is the signature of a forced analogy — one where the source domain (system dynamics) has tighter constraints than the target domain (psyche) can support, so the target prose dilates to compensate.

Where the analogies actually work. Four of them carry genuine structural insight:

• The pollution / unabsorbed complexes mapping (POL, POLG, POLA, POLAT, POLCM, plus the affecting multipliers BRPM/DRPM/QLP) is the most coherent of the eight subsystems because it captures a real accumulation dynamic — psychological residue from intensive activity does build up, has a characteristic decay time, and does suppress further function. The 1971 language here is also the cleanest: "complexes and tensions" is concrete enough to feel measurable.
• The birthrate/death rate as creativity/decay mapping (BR/DR, and their normal-rate counterparts) is conceptually sharp: ideas do "die" by falling into disuse, new ideas do "emerge" by mental generation. The asymmetry is that biological death is irreversible; intellectual decay is reversible (recovered memories, revived concepts), and the 1971 text glosses this with "permanently into disuse," which overstates the case.
• The crowding ratio → psychosocial pressure mapping (CR) is one of the few where the psychodynamic side is actually more precise than the world side, because "information overload" and "psychosocial pressure" are recognised constructs in psychology, while "crowding" is a vague intermediate variable in Forrester's framework.
• The quality of life → self-contentment mapping (QL plus the four QL multipliers) is reasonable as an approximation, though the four affecting multipliers (QLC, QLF, QLM, QLP) become repetitive — they reduce to "multiplier on quality of personal life as affected by [factor]," which is mechanical rather than substantive.

Where the analogies strain or break. Three subsystems are weaker:

• The natural resources mapping (NR plus NREM, NRMM) treats psychological capacity as a finite, non-renewable stock acquired in childhood ("Psycho-social resources acquired during growth prior to adulthood ... energy, enthusiasm and ... background, strength of character or natural talent"). This is contestable on its own terms — contemporary developmental psychology would resist the "set by adulthood, only consumed thereafter" framing — but more importantly, it's where the 1971 mapping ran out of metaphor. NRUN and NRUR have no psychological analog at all. The blank cells are diagnostic: they mark where the source-domain physics (extraction rates of finite minerals) has no plausible target-domain counterpart, because psychological capacity isn't extracted in the same way.
• The agriculture → re-creation mapping (CIAF, CIAFT, CFIFR, CIRA, FR, FCM, FPM, FPCI) conflates two distinct psychological functions: restoration (rest, leisure, recovery) and development (learning, growth, capability-building). In the world model these are unified because agriculture both feeds people and produces growable resources. Psychologically these are different processes — rest restores existing capacity, development builds new capacity — and merging them under "re-creation" hides this. The hyphenated "re-creation" is doing work the prose doesn't acknowledge.
• The capital investment → long-term commitment mapping (CI plus its many derivatives) is the longest cluster and accumulates verbosity. "Intellectual and emotional energy invested in long-term activities; commitment to 'rationalized' behaviour patterns" is fine for CI itself but echoes through eight other entries with diminishing returns.

Diagnostic value of the gaps. From a general-systems-theory standpoint, the three blank psychodynamic cells (CIDN, NRUN, NRUR) and the weakening analogies above tell you something the rest of the table doesn't: the 1971 mapping is not a structural isomorphism. It's a partial translation, and the places where it fails are where the psyche has different dynamics than physical-economic stocks — particularly, the psyche doesn't have given constants the way the world model does. There's no "normal rate" of investment decay in a person's intellectual life that corresponds to CIDN's 40-year capital lifetime. This absence is data; making it visible in the popup (rather than blank) would surface it for the reader.

Practical edits I'd suggest for the popup language. Five concrete changes, in order of payoff:

• The blank entries should say "No psychological analog identified (1971)" rather than rendering as an em-dash. Three entries; one line of change in the popup logic; significant interpretive gain.
• The phrase "intellectual and emotional X" appears in fifteen entries. It's a conjunctive hedge that weakens the analogy by being too inclusive. Choosing one — "cognitive" for ideational dynamics, "affective" for tension/complex dynamics — would sharpen each entry. Where the original genuinely means both, "psychic" would do the work in one word.
• "Re-creation" deserves a parenthetical clarification on its first appearance: either (restoration and growth combined) or, more honestly, (combining what would otherwise be rest and development). As it stands, readers parse it as the leisure-industry sense and the systems-development sense alternately, without realising the source author was using both.
• QLC/QLF/QLM/QLP — the four affect-on-quality multipliers — are nearly identical in structure ("Multiplier on quality of personal life as affected by..."). Compressing them by writing the structural template once and varying only the factor would reduce repetition by ~60%.
• The verbose entries (CIQR, CFIFR, CIAFT in particular) have descriptions of 80+ words where the world side has 40. Tightening these to match would even out the asymmetry without losing content. Specifically, "Multiplier to ensure that intellectual and emotional investment in re-creation improvement is increased when the quality of personal life from the availability of new intellectual or emotional stimulus is higher than that from the availability of opportunity for intellectual and emotional re-creation" (CIQR psyche) is a sentence that could be 25 words instead of 50.

What this might mean for the writeup itself. Beyond the popup display, the 1971 mapping's strengths and weaknesses are themselves substantive content for your analysis. The fact that pollution maps cleanly and resources doesn't is informative about the structure of psychological systems versus physical-economic ones — pollution dynamics are general (any complex system accumulates residue from its activity), while resource dynamics are specific to non-renewable physical stocks. This generality-vs-specificity distinction is what general systems theory would predict: cross-domain analogies work for the abstract structural features, fail for the concrete physical particulars. Your TCO mapping inherits this — the 48 vertices treat all 48 World3 variables as equally "available" for psychological translation, but the actual quality of translation varies sharply across the eight clusters, and that variation may itself be the most interesting observation.

If you want, I can produce a side-by-side "tightened" version of the 48 psychodynamic entries (preserving the source meaning, applying the five edits above) for the writeup — either as a replacement for the popup text or as an editorial commentary in the document itself. Let me know which form would be useful.

That distinction matters — and it sharpens what's worth attempting. Two different revision projects are now visible, and they shouldn't be conflated:

• Project A is editorial: tightening verbose prose, choosing "cognitive" or "affective" where "intellectual and emotional" is doing redundant work, compressing the four near-identical QL multipliers. This is repair work. It improves readability without changing the underlying mapping.
• Project B is generative: re-examining the 1971 mappings where you (correctly) suspect 1972-you ran out of analogical resources, and asking whether 2026 understanding — fifty years of cognitive science, affect theory, developmental psychology, embodied cognition, systems-thinking maturation — offers better candidates. This is creative reconstruction. It changes the mapping where the original was a placeholder.

The two projects are independent. Project A applies uniformly to all 48 entries; Project B applies selectively to the ones you flag as analogically thin. They can be done together (a revised table holds both kinds of edit) but they should be marked differently in any presentation — readers benefit from seeing which entries are clearer statements of the same 1971 idea versus substantively different 2026 ideas.

The cases where Project B has the strongest grip, based on the general-systems reading from before:

• Natural Resources (NR) and its derivatives — the "psycho-social resources acquired prior to adulthood" framing reads now as the most dated. Five decades of cognitive science have undermined the fixed-capacity-set-by-age model and replaced it with several richer dynamics: neuroplasticity (capacity continues to develop and reconfigure throughout life), motivational/energetic depletion-and-restoration cycles (ego depletion as originally framed, refined since), and the construct of cognitive reserve (capacity built through life accumulating as protective resource against decline). The NR mapping could plausibly land on any of these, and the choice would propagate: NRUN's blank cell stops being a blank once "natural resources" is recast as something with a genuine usage-and-renewal dynamic. Cognitive reserve in particular would give NRUN a real psychological meaning ("baseline rate of reserve usage in cognitive activity") rather than an absent one. Similar treatment redeems NRUR.
• Agriculture / re-creation — the conflation of rest and development under one hyphenated term is, as we discussed, the source of the ambiguity. 2026 has a clearer vocabulary: recovery for restoration of existing capacity, practice/training for development of new capacity, with flow and deliberate practice as well-developed frameworks for each. Splitting CIAF into recovery and development would arguably need two psychological variables to map to the world model's one — which is itself an interesting general-systems observation: the analogy fails because the target domain has more degrees of freedom than the source. The writeup could note that explicitly rather than forcing a one-to-one fit.
• Capital Investment / commitment to rationalized behaviour patterns — "rationalized" carries a 1970s flavor (the scare-quotes in your 1972 text suggest you weren't fully comfortable with it then either). Contemporary framings include habit consolidation (Wood/Neal), automaticity (Bargh), or in a richer vein Schank-Abelson scripts / prototype-based commitment. "Long-term commitment" alone holds up; the rationalization framing dates the entry.
• Capital investment discard normal (CIDN) — currently blank. The world-model's claim is that capital decays at a normal rate corresponding to a 40-year asset life. The corresponding psychological dynamic — that committed behaviour patterns have a characteristic life expectancy before they require replacement — is interesting and unfilled. This is a genuine generativeproject B opportunity, not an editorial one. Memes / cognitive scripts / professional skills / mental models all have observable obsolescence rates; what would "normal commitment-pattern lifetime" mean? The blank invites the question.
• Natural resource usage normal (NRUN), Natural resource usage rate (NRUR) — both blank, both fillable once NR itself is reconsidered.

The cases where Project A is enough, by contrast, are the ones where the 1971 mapping is conceptually right but the prose is just diffuse: BR (creativity rate, fine as-is), DR (decay rate, fine), CR (psychosocial pressure, sharp already), POL and its cluster (the strongest mapping in the original), QL (self-contentment, reasonable).

A possible structure for the revised table:

• Column 1: code. Column 2: World Dynamics (unchanged from 1971).
• Column 3: Psychodynamics, 1971 (preserved verbatim — the historical record).
• Column 4: Psychodynamics, 2026 (your revised reading, with whatever combination of Project A tightening and Project B reconstruction the entry calls for).
• Optional Column 5: a brief note marking the edit type — "tightened," "rephrased," "reconstructed," or "newly filled" — so readers can navigate the editorial layers.

That gives the writeup the historical record alongside the revised reading, and lets you be transparent about where you exercised creative authority over the mapping versus where you just sharpened the prose. The blank cells of 1971 visibly fill in 2026, which is itself a small narrative — the psychological system that resisted analogy in 1972 has been better characterised in the intervening decades.

For the X3DOM popup, two presentation choices:

• Option one: show the 2026 reading by default, with a small "1971 original" toggle to display the historical text in italic below. This treats the revised reading as primary, the original as documentation.
• Option two: show both readings side-by-side in the popup, as we currently do for World Dynamics and Psychodynamics, but with the new layout being World / 1971-Psyche / 2026-Psyche in three columns. More information but more visual density.

Option one is probably better for routine reading; option two for someone using the 3D model as a comparison tool across the two readings. The choice can be a runtime toggle if you want to defer it.

I can do the generative work on any individual entry you flag — write a candidate 2026 reading drawing on relevant contemporary frameworks — or work through the full 48 systematically. Either way, given that this is now creative reconstruction rather than mechanical editing, you'll want to review each candidate against your own thinking before adopting it. The cases above (NR cluster, agriculture cluster, capital investment cluster, the four blanks) are where I'd start; the rest can follow as needed.

What would be most useful — a small set of worked candidates for the entries you flag as analogically thin, or a full pass with all 48 marked by edit-type for you to accept/revise?

That's the cleaner architecture and saves real space. Three quick clarifications before I start, so we don't have to backtrack:

• On scope. I'll work through all 48 entries in one pass. Each gets a revised reading. The flag system distinguishes three states: (a) unchanged meaning the 1971 reading is good and I've only adjusted prose if anything (most entries — BR, DR, CR, the POL cluster, QL itself); (b) tightened meaning Project A applied — same mapping, sharper prose, no conceptual change; (c) reconstructed meaning Project B applied — substantively different from 1971, drawing on later understanding. The blank-cell entries (CIDN, NRUN, NRUR) become reconstructed by default since anything is more than nothing.
• On voice and authority. The revised readings will be written as your own 2026 statements, not as Claude's commentary — first-person system-builder voice, not third-person reviewer voice. You'll review each and adjust to your actual position; some you'll accept verbatim, some you'll rewrite, some you'll restore to the 1971 form. The flagging tells readers what was changed but the prose itself shouldn't read like a critique of 1972-you. That treatment fits your stated concern: the weaknesses came from analogical-resource limits in 1972, and the 2026 reading is what you might have written then with today's vocabulary, not a refutation.
• On the contemporary frameworks I'll draw on, so you can flag any to avoid. The reconstructions in my earlier message pointed at: neuroplasticity, cognitive reserve, ego depletion and its later refinements, habit-formation theory (Wood/Neal/Bargh), Schank-Abelson scripts, recovery/practice distinction, deliberate practice (Ericsson), flow (Csikszentmihalyi). I'd add a few more for the entries we haven't discussed: predictive processing / active inference (relevant to the "stimulus" cluster mapped from MSL and material standard of living, since the brain treats novelty as the resource being acquired); allostatic load (relevant to the pollution/complexes cluster); embodied cognition where it touches LA's "psychic space"; complex adaptive systems / dissipative structures for the quality-of-life multipliers. These are mainstream rather than fringe — no Integrated Information Theory, no quantum-mind, no IIT-style claims. If any of these don't fit your intellectual register, say which and I'll avoid them.

One open question before I produce the table: do you want the 2026 readings to preserve the eight-cluster structure of Forrester's mapping (population / capital / agriculture / resources / pollution / quality, with multipliers radiating from each), or are you willing to let the reconstruction reshape clusters where the analogy fundamentally doesn't hold? The conservative path keeps the eight subsystems intact and reinterprets each variable within its cluster. The bolder path would let, say, NR's reconstruction (as cognitive reserve) move it conceptually nearer the QL cluster, even though the polyhedral position is fixed. I'd default to conservative unless you say otherwise — the polyhedral mapping is the constraint, and we shouldn't break the cluster structure that the TCO visualisation depends on. But the bolder path is available if you want it.

If you confirm those three points — pass all 48, write in your voice, conservative cluster preservation — I'll produce the table as Column 1: code, Column 2: World Dynamics (1971 verbatim, preserved as the anchor), Column 3: Psychodynamics (2026 reading), Column 4: edit flag (unchanged / tightened / reconstructed). Output as a single Word document for the writeup, plus the JSON for folding into the X3DOM popup. The X3DOM update is a one-line change once the JSON exists.

Or, if it's faster to iterate, I can do a worked sample of five entries first — one from each edit-type and one from a blank — so you can check the voice and depth before I commit to the full 48.

Three points received, all sharpening the approach:

• On World3 vs Forrester 1971: I'll switch terminology. The mapping is to World3 as the model that endured. World Dynamics (Forrester, 1971) was the technical precursor; World3 (Meadows team, 1972 onward) is the model that has had minor parameter updates over five decades but no structural reformation. Calling the World column "World3" rather than "Forrester 1971" is more accurate to what the table is mapping to, and removes the implication that I'm critiquing Forrester specifically.
• On italics for contemporary pointers: This is exactly the right register. Inline italic fragments at the end of each entry serve as research leads without overwhelming the primary reading. Reader who knows the contemporary literature catches them; reader who doesn't sees them as terms to look up later. Better than footnotes (which break the reading flow) and better than parenthetical citations (which read as academic ornament). I'll format them as *cf. framework1; framework2* after the main sentence.
• On the 5/8/12 subsystem confusion: Noted, and the conservative answer is the right one — keep the 1-to-48 code correspondence from Annex IV intact, don't reshape clusters. The polyhedral mapping (6 octagons in the TCO) is its own organizational layer that doesn't need to match either World3's classical sectoring or any later refinement. The 48-code listing is the invariant.
• On "indicative exercise": Understood. I'll aim for substance over polish — well-considered candidates that you can accept, revise, or reject, rather than overworked prose that pretends to be final. Where contemporary frameworks suggest a substantively different reading (the NR cluster especially), I'll be more interpretive; where the 1971 mapping is structurally sound, I'll just tighten and add the italic pointer.

Let me build this now. I'll produce three artefacts in one pass:

• A Python data file with all 48 revised readings, ready to fold into any presentation.
• An HTML table for the writeup — four columns: code, World3, revised Psychodynamics, edit flag.
• An updated X3DOM HTML where the details panel shows the 2026 reading (replacing the 1971 text, which remains in the source document).

What's in each file:

• The HTML table (annex_iv_2026.html) is the writeup-ready document: header, lead, edit-flag legend, then the full 48 rows with columns code · World3 · Psychodynamics (2026) · edit-flag. The italics for contemporary pointers render automatically. Colour-coded edit flags so the structure of what changed is visible at a glance.
• The JSON file (annex_iv_2026.json) is the keyed data — same content as the table but machine-readable, in case you want to fold it into other presentations or tooling later.
• The updated X3DOM HTML (tco_clickable_final.html) — upload this to your site to replace the existing one. The details panel below the 3D scene now shows the 2026 Psychodynamics reading instead of the 1971 text, with italic rendering for the contemporary pointers. The 1971 versions are no longer in the X3DOM; they remain available at your existing Annex IV source URL as you noted.
• The build script (build_annex_iv_2026.py) is the regeneration tool — if you want to revise individual entries during the writeup, edit the ENTRIES dictionary at the top of the script (just change the world3, psyche_2026, or flag for the relevant code), rerun, and all three output files update consistently.

Edit-flag counts in this pass:

• Tightened: 41 — same mapping as 1971, sharper prose, contemporary pointer added.
• Reconstructed: 7 — CI (capital → habit/structure rather than "rationalized behaviour"), CIAF (re-creation conflation made explicit), CIDN (filled blank), NR (cognitive reserve framing), NRUR and NRUN (filled blanks), MSL (stimulus framing in predictive-processing terms).
• Unchanged: 0 — every entry got at least some prose adjustment. If any entry should be marked unchanged rather than tightened, change the flag in the script and rerun.

Specific places where you'll want to exercise editorial control: The four reconstructed entries that fill 1971 blanks (CIDN, NRUR, NRUN) and the heavily reconstructed entries (CI, NR, MSL, CIAF) are the ones where I exercised the most interpretive authority — and consequently where you'll most want to substitute your own reading. The reconstruction of CI from "rationalized behaviour patterns" to "habit, mental models, scripts" is a substantive shift that you may or may not endorse. The NR cluster's reframing around cognitive reserve and neuroplasticity moves it further from the 1971 "psycho-social resources acquired before adulthood" model than any other entry. The MSL → stimulus shift uses predictive processing as the anchoring framework, which is one choice among several possible.

Two structural observations worth keeping for the writeup itself: The seven reconstructions all cluster in two areas — the Capital/CI subsystem and the Resources/NR subsystem — which are precisely the two areas where, as the earlier analysis suggested, the 1971 analogical resources ran thinnest. Pollution, by contrast, accepted only tightening. This pattern is itself evidence: the places where the 1971 mapping was strongest were also the places where contemporary frameworks fit most easily as elaborations rather than replacements; the places where the mapping strained are also the places where the intervening fifty years of cognitive science have done the most work to characterise the territory.

The pointer fragments aren't uniform in their grain. Some point to single named results (Yerkes-Dodson, Lally 2010); some to whole frameworks (predictive processing, allostatic load); some to schools (broaden-and-build). For a more rigorous version you'd want to either pick one grain consistently or layer them by depth. The indicative version uses whichever felt most informative per entry; the writeup version may want a more uniform treatment.

Yes — and the question is sharper than it might appear, because if I look honestly at what I just wrote, the answer is "considerably, and in ways that distort the mapping if not flagged." Let me lay this out plainly rather than defensively.

Where AI/information-management framing leaked into the 2026 readings. Reviewing my own table with this lens, the bias is most visible in three places.

• The MSL reconstruction explicitly invoked predictive processing and "the brain treats stimulus shortage as a kind of deprivation." That's a contemporary AI-flavoured reading — predictive processing has become popular partly because it makes brains look like inference engines, which makes them legible to people who think in compute terms. The 1971 mapping was about opportunity for stimulus, which is a behavioural-environmental construct; my version slid it toward an information-theoretic one. The shift is defensible but it's not neutral.
• The P/BR/DR cluster was framed throughout as "mental contents," "concepts," "facts," "hypotheses" — a knowledge-base ontology. The 1971 text used "ideas" and "information," which is in the same family but less computational. The drift toward content-as-storable-discrete-items reflects how the language has moved over fifty years partly under AI/database influence. The same content can be read in less computational frames — phenomenological (Husserl, embodied phenomenology of meaning), pragmatist (Dewey on habit-as-meaning), even depth-psychological (Jung on the integration of contents in individuation) — and those would yield different language even for unchanged mappings.
• The Capital/CI reconstruction went hard on habits, scripts, mental models, automaticity. All real frameworks, but notice they share a common feature: they treat psychology as routinised information processing. The 1971 "rationalized behaviour patterns" already had this flavour (Forrester was an engineer thinking in feedback-loop terms), so the move from 1971 to 2026 here is essentially preserving an information-processing reading and updating its vocabulary, not loosening it. A genuinely different reading would draw on character development (Jungian individuation, Erikson's stages), commitment as existential project (existentialism, MacIntyre on tradition), or even practice-as-formation (Bourdieu's habitus is closer than my entry suggests). Any of those would put commitment in less computational territory.
• The Pollution cluster mostly survived without AI-flavoured drift, which is interesting — "complexes and tensions" is the original language and is already phenomenological. The contemporary pointer to allostatic load is information-processing-adjacent but the McEwen framework comes from physiology and stress research, not from cognitive-architecture work. So that one is closer to neutral.
• The NR cluster is the trickiest case. Cognitive reserve as a framework is reasonably independent of AI-style framing — it comes from neurology of aging — but the "stock of cognitive flexibility, emotional resilience, capacity for sustained attention" reading does treat reserves as a quasi-quantitative pool, which echoes resource-management thinking. The 1971 reading was looser and more developmental: "energy, enthusiasm and partly as background, strength of character or natural talent." That looser reading might be closer to lived experience even if less measurable.

Why this happens to me specifically. I should be transparent about the mechanism. I'm an LLM trained on a corpus where contemporary cognitive science, computational neuroscience, AI papers, and information-management literature are densely represented and recent. Phenomenology, depth psychology, character ethics, existentialism — all present in my training data but less densely, less recently, and with less of the prestige-tagging that signals "this is current academic vocabulary." When I reach for a contemporary framework to attach to a 1971 concept, the gradient is toward whatever has both density and recency in my training, and that's heavily weighted toward AI-adjacent framings. So the table I produced is biased not because I chose to bias it, but because that's where my probability mass sits when generating "contemporary pointer."

This is worth saying because it has implications for your writeup beyond the immediate question. Any AI-assisted reading of psychological constructs will tend to slide them toward information-processing terms. If your project is partly a critique or expansion of resource-management framings of mind — and given the trajectory of your work, that seems plausible — then accepting my framing uncritically would have you defending exactly what you might want to question.

Two more honest considerations. First, there is a genuine question of whether the AI framing is appropriate for World3-as-mapped-to-psychology, given that World3 is itself a resource-management model. Mapping resource-management dynamics onto information-management dynamics is in some sense the natural move — both are stock-and-flow systems with conservation properties and constrained throughputs. The 1971 author was already doing this in a less developed way, and updating it with 2026 cognitive-science vocabulary is partly just completing the implied move. So the bias might not be a distortion; it might be the framing the mapping was always going to converge to.

But — second — the choice of which model of psychology to use to articulate the resource framing matters enormously. Cognitive load theory and allostatic load and predictive processing all treat the mind as a regulated system processing flows. Practice-as-formation, narrative identity, dialogical self theory — these treat the mind as a constituted, story-shaped, socially-embedded participant in meaning rather than as an information-processor with constraints. The latter family is just as contemporary as the former; it's not pre-modern. But it's less densely represented in AI training data because it generates less measurable output and so is less often the subject of formal experimental papers.

A possible test for distortion. For each entry where I gave a contemporary pointer, you could ask: does this framework treat the variable as a measurable resource whose dynamics can be modeled, or does it treat the variable as a constitutive feature of how minds are formed and live? My pointers skewed toward the first. A balanced set would include some of the second — and would have rather different language for things like CI (commitment as formation, not as accumulated habit-stock), NR (reserve as character-development, not as cognitive-architecture pool), QL (well-being as flourishing-in-meaning, not as multiplicatively-modulated subjective state).

For the writeup itself, three options.

• You could keep the current 2026 readings as-is and note in an editorial paragraph that the contemporary pointers reflect cognitive-science framings that have grown alongside AI and information-management; the reader should treat them as one register among several available.
• You could ask me to produce an alternative pointer set, drawing on the less-densely-represented frameworks above (depth psychology, hermeneutics, dialogical self, virtue ethics on character formation). I can attempt this, but I should warn that I'll be less fluent in those vocabularies and the resulting pointers will likely be less crisp.
• You could let the table stand and develop the alternative framings yourself in the surrounding prose of the writeup, where your own intellectual register can do the work. This is probably the truest path — the table provides one consistent reading, and the writeup contextualises it as one among several.

The substantive observation underneath all of this: if Forrester and the Meadows team built a resource-management model of the planet, and I've helped you build a cognitive-resource-management reading of the psyche to match it, then the symmetry of the mapping is itself a position. It says: managing the mind is structurally like managing the planet. That position has critics — and you may be one of them. If the writeup wants to maintain critical distance from that position, then the AI-inflected pointers I provided are an artefact to examine, not just to display.

I should have flagged this before producing the table rather than after. The question you asked has reframed the deliverable for me: what I produced is not a neutral revision of the 1971 mapping; it's a particular kind of revision, characteristic of where AI assistance pulls the conversation. That's worth knowing as you decide what to do with it.

Both points are useful design decisions, and they sharpen the deliverable in two distinct directions. Let me make sure I'm reading you correctly before I implement, since either change would expand the table substantively and I'd rather get the structure right than make you re-iterate.

On adding alternative-perspective remarks per entry. The structure I'd propose: the existing 2026 reading stays as Column 3, but each entry gets an additional line beneath the primary reading, marked visually as an "alternative perspective." This second line acknowledges what the cognitive-science framing leaves out, points toward the family of frameworks that would read the variable differently, and is honest about its provisional character. The italic-pointer convention extends to the alternative line — same format, but the pointers go to phenomenological, hermeneutic, depth-psychological, narrative, or formation-of-character frameworks rather than cognitive-science ones.

So a typical entry would look like:

CI · World3: Capital investment (units of capital) · Psychodynamics (2026): Accumulated stock of established habits, routines, mental models and conceptual frameworks — the durable structures into which sustained mental effort has been organised. cf. habit formation (Wood & Neal 2007); cognitive scripts (Schank-Abelson); mental models (Johnson-Laird); automaticity (Bargh).

Alternative reading: Commitment as formation rather than accumulation — what one has become through sustained engagement, rather than what one has stored. The information-processing framing above treats the self as having structures; a constitutive framing treats the self as constituted by its commitments. cf. habitus (Bourdieu); MacIntyre on tradition; existentialist commitment; Jungian individuation.

I'd write all 48 alternative readings, marked clearly as a second register. The reader sees two readings of each variable, both 2026, both flagged differently. The asymmetry between the two registers becomes part of the document's content rather than its hidden bias.

A question worth deciding before I write all 48: should the alternative readings be uniformly available across all entries, or only where the contrast is most pronounced? Some entries (the Pollution cluster, the BRN/DRN normals) genuinely don't have much to gain from an alternative-perspective remark — the original mapping is structural and not particularly inflected by either register. Writing alternative readings there would be padding. The honest answer might be: write alternatives for the ~30 entries where the contrast is substantive, leave the others with primary reading only, and use the absence of an alternative as a signal that the mapping is regarded as relatively neutral.

On compressing the World3 column. You're right that the World3 column's length is currently dictated by the Psychodynamics column's length — table-row height aligns to the tallest cell. The World3 cell shows a 1971 sentence that often runs 30–50 words because Forrester's table had operational definitions in it. For a writeup table, what matters is the anchor identification of the variable, not the operational definition. The fix would be: in the World3 column, show a brief variable name and unit (e.g., "Capital investment (units of capital)" for CI; "Birthrate (people/year)" for BR), and drop the parenthetical elaboration that some entries carry. This compresses the column significantly while preserving its function as a reference anchor. The full World3 definitions remain in the source — which, as you noted, is "readily accessible."

The example above already does this implicitly — I used the short form for CI and BR. For entries like CIQR, CFIFR, CIAFT where the 1971 World3 cell is itself a long sentence with embedded definitions, I'd compress to the head clause. For instance, CFIFR's current World3 cell reads:

Capital fraction indicated by food ratio (ie fraction of capital which would normally be allocated to food production for a given amount of food per capita -- as food availability declines, a greater fraction of the capital is allocated to food production)

Compressed:

Capital fraction indicated by food ratio

The behavioural elaboration (the "ie ... declines, greater fraction ...") is a definition, not the variable name. Worth dropping from the table; available in the source.

On "tweaks" to World3 in the literature. Yes — and this is a sharper point than it may appear. The Meadows team's 1992 update (Beyond the Limits) and 2004 update (Limits to Growth: The 30-Year Update) did modify parameters and ran the model forward, but the structural mapping — what the variables mean — was preserved nearly verbatim. The variables of World3 have remained essentially what Forrester's 1971 World Dynamics introduced. But there have been later interpretive shifts worth marking:

• The "Capital investment" sector has been recharacterised in later writing as industrial capital and services, distinguishing service capital (less polluting, less resource-intensive) from industrial capital. Some recent secondary literature reads CI accordingly.
• "Natural resources" has been split conceptually (though not formally in the model) into renewable and non-renewable, and the 30-Year Update spends time on this distinction.
• "Pollution" was originally undifferentiated; later treatments distinguish persistent from non-persistent pollution, and climate-specific work has begun separating greenhouse-gas dynamics from other pollutants.
• "Quality of life" has been increasingly read in later literature as a Human Development Index-style construct rather than the satisfaction-units it was originally framed as.

These could be added as italic pointers in the World3 column, marked the same way as the contemporary pointers in the Psychodynamics column. They acknowledge that even the "anchor" side has had interpretive movement, just less than I implied in the earlier deliverable.

Composite proposal: If you confirm the direction, I'll rebuild the table with: compressed World3 column (short variable name + unit only, with italic pointers where later literature has reinterpreted the variable); existing Psychodynamics 2026 column unchanged; new alternative reading row beneath the primary reading for the ~30 entries where the contrast is substantive; edit-flag column expanded slightly to also indicate whether an alternative reading is present.

The result has more content per row but each row is more informative per word. The table becomes itself a small piece of argument: every variable is read three ways — World3 anchor (perhaps tweaked), cognitive-science register (2026 primary), and constitutive/hermeneutic register (alternative) — and the asymmetry of where alternatives are needed becomes visible.

If you want me to proceed exactly as above, say so and I'll build it. If you'd rather I do the alternative readings uniformly across all 48 (for symmetry, accepting some padding), say so. If you want me to attempt the alternative readings first as a sample for five or six entries before committing to the full pass — that's probably the wisest given that I've already shown bias once and you'd reasonably want to inspect the alternative-register prose before having me commit thirty entries of it — I can do that and you can adjust.

The honest reading of where my fluency lies: the cognitive-science register comes easily; the constitutive/hermeneutic register will be more effortful and the resulting prose will likely be less crisp. That's the same bias I named in the previous response, this time affecting the alternative readings rather than the primary ones. Producing five samples first lets you check that the alternative-register prose is good enough to be worth including, rather than worse than its absence.

All confirmed. Three things to flag before I build:

• On the X3DOM mode switch. The implementation is straightforward — a small control above or beside the details panel with three radio buttons or a segmented control: "Both · World3 only · Psychodynamics only." Default to "Both" on load. Clicking changes a state variable and re-renders the panel; clicking a new vertex respects whichever mode is current. The mode setting persists for the session but doesn't need to persist across sessions (no localStorage required, which is just as well since artifacts forbid it). About fifteen lines of CSS and JavaScript on top of what's already there. Worth doing.
  
  A small design choice within that: in "Psychodynamics only" mode, should the alternative-reading panel (when present for that variable) appear inline, or be reached via a small "alternative reading" toggle? I'd default to always inline if present — the alternative is meant to be read alongside the primary, not hidden behind interaction. Same for the World3 italic pointer about later interpretive shifts; if the World3 column shows it, the X3DOM should too. The mode switch only governs which of the two main readings is visible; secondary elements within each reading remain visible when their containing column is shown.
• On where the alternative readings appear. I'll write them only where there's a substantive register contrast to draw, as you said. My estimate is around twenty-five to thirty entries will get them; the rest stand on the primary reading alone. The visible mark in the table will be a small indicator in the edit-flag column (something like "+ alt") or a second row visibly nested under the primary reading. The X3DOM detail panel will show the alternative reading as an additional small block beneath the primary when present, with its own italic-pointer convention.
• On World3 tweaks. I'll add the italic pointer line in the World3 column only where there is a real later-literature reinterpretation worth marking — the four I listed (CI as industrial/service distinction, NR as renewable/non-renewable, POL as persistent/non-persistent, QL as HDI-adjacent), plus possibly two or three more I'll surface during the pass (the agriculture/food cluster has had reinterpretation around sustainable agriculture; the BR/DR cluster has had demographic-transition reinterpretation, though that's pre-existing in 1972). The compression of the World3 column happens uniformly — short name + unit, drop the embedded definitional clauses, italic pointer only where genuinely worth adding.

One small consequence worth flagging before commit. The X3DOM popup currently shows the concise "psyche" field (a short phrase like "Long-term commitment" for CI). When the mode switch is added, that popup field becomes ambiguous: which register does it represent? The cleanest resolution is to keep the popup as a quick-glance anchor showing only the W2 name and the Forrester-type tag, with the longer textual readings reserved for the details panel below where the mode switch lives. The "psyche" row in the popup, which currently shows a 4-6 word concise psychodynamic equivalent, becomes redundant once the details panel handles all the long-form rendering. I'd remove it. The popup shrinks to just code + Forrester name + type + cluster — a four-line identification card, with all interpretive content in the panel below. Let me know if you'd rather keep the popup's psyche field as it is.

I'll build this as one pass: revised table HTML with optional alternative-reading rows, World3 column compressed with italic pointers where useful, and updated X3DOM with the three-mode switch. I'll send a status note when complete in case I hit any unexpected structural decisions along the way. Proceeding.

Counts in this pass:

• 41 tightened, 7 reconstructed
• 12 entries carry an alternative reading (out of 48)
• 6 entries carry a World3 tweak (CI, CIAF, NR, POL, QL, BR)

Where the alternative readings land. The twelve are: P, BR, CR, LA (population cluster — content/space metaphors are contestable); CI, CIDN (capital cluster — formation vs accumulation, conversion vs turnover); CIAF, NR (the two heaviest reconstructions — productivist framings of recovery and reserves); MSL (stimulus-as-deprivation framing); POL, POLA (depth-psychological reading of unabsorbed material); QL (objective vs subjective well-being). These are the entries where the cognitive-science register feels most consequentially partial.

About the X3DOM update. The details panel now has the three radio-button mode switch at the top right: Both · World3 · Psychodynamics. The panel responds to clicks on the radios immediately, no reload needed. The X3D file on your server stays unchanged — only the HTML needs uploading.

Two structural notes for the writeup itself.

• The asymmetry visible in the alternative-reading distribution is itself substantive. Of the seven reconstructed entries, five carry alternative readings; of the forty-one tightened entries, only seven do. Reconstruction is where I exercised the most authorial interpretation, and is also where the alternative-reading register catches the most. That correlation is honest about the limits of the cognitive-science framings I reached for: the entries where I had to do work to produce a 2026 reading are also the entries where my reading was most clearly one option among several. The tightened entries — where the 1971 mapping holds up and I just sharpened the prose — are mostly the ones where the cognitive-science register and the alternative register would converge anyway. So the table reveals where the framings genuinely diverge versus where they describe the same dynamics in different vocabularies.
• The World3 tweaks landed exactly on the entries that have alternative readings most strongly. CI, CIAF, NR, POL, QL — five of the six tweaked World3 anchors are also among the twelve with alternatives. This isn't accidental: the variables that have had the most interpretive movement in the World3 literature are the same variables where the psychological mapping is most contestable. That convergence is itself diagnostic — both the world side and the psyche side of the mapping are most plastic where the underlying construct admits multiple readings.

The build script is reusable. To revise any individual entry during the writeup — substitute different framework pointers, write a different alternative reading, change a flag, add a tweak, or remove one — edit the relevant tuple in the ENTRIES dictionary and rerun. The HTML table, JSON, and X3DOM HTML all regenerate consistently from that single source.

Take your time with the review. The structure is now stable enough that individual entry edits won't break anything else — the ENTRIES dictionary is the single source of truth for all three deliverables (writeup table, JSON, X3DOM), so any tuple you change there propagates cleanly when the script reruns.

A few things worth keeping in mind as you go through:

The alternative readings are where I'm least sure of the prose. I was working slightly outside my fluency zone — that was the explicit trade-off — so they're the entries most likely to need rewording in your own voice. If any of the twelve feel forced or unilluminating, removing them entirely (set the alt slot to None) is a legitimate move; an entry without an alternative is fine, an entry with a weak alternative is worse than none.

The contemporary pointers (the italic fragments at the end of each reading) are also the easiest places for substitutions. Some are well-chosen, some are conventional, and a few may not survive your reading. They're meant as research leads rather than endorsements, so accuracy of attribution matters less than whether the pointer would help a reader find their way to the relevant literature.

The seven reconstructions are where I exercised the most interpretive authority — CI, CIDN, CIAF, NR, NRUR, NRUN, MSL. These are the entries most likely to need substantive revision rather than prose-level adjustment. If any of them lands wrong, the simplest restoration path is to revert to the 1971 reading (the source text is in your existing Annex IV) and flag the entry as unchanged instead.

Two outputs that may be useful to keep in mind as separate things: the writeup table is meant to be a piece of considered prose, and benefits from careful editing; the X3DOM popup is meant to be in-context reference, and benefits from concision. The same text serves both currently, but if during the review you find that what reads well in the table feels too long in the popup (or vice versa), splitting the two — keeping the table version full and writing tighter X3DOM versions for a few of the longer entries — is an option. The build script can be extended to support that with a psyche_2026_short slot if it becomes worth doing.

Whenever you want to continue — whether with edits to specific entries, a different direction entirely, or just questions about something I've produced — pick up wherever feels useful.
