Abstract

Model collapse — the progressive narrowing of a generative system's output distribution through recursive training on its own outputs — is studied as a property of large language models. This paper argues it is not a property of language models. It is a property of language.

Any system that processes language — biological or artificial, neural network or infant brain — requires diverse input to develop and maintain its generative capacity. When input diversity contracts below a critical threshold, the system's capacity narrows irreversibly. This is not an analogy. It is the same dynamical regime operating in different substrates.

The evidence comes from three substrates. In silicon: recursive training on model outputs produces measurable tail loss and distribution narrowing (Shumailov et al. 2024). In adult human cognition: sustained interaction with AI systems produces measurable homogenization of writing, even in text produced without AI assistance (Doshi & Hauser 2024; Padmakumar & He 2024). In developing human cognition: children deprived of diverse linguistic input during the critical period suffer permanent, irrecoverable capacity loss — the feral child cases (Curtiss 1977; Itard 1801; Lenneberg 1967). The analogy across substrates is dynamical, not moral: the paper does not claim that AI use is equivalent to child deprivation. It claims that the same regeneration-pruning dynamics govern all three systems.

The three substrates are governed by the same boundary law (Sharks et al. 2026, Diversity Contraction): a system whose regeneration term vanishes faster than its pruning term near zero diversity has a bistable trap — a threshold below which recovery is impossible. The feral child is the biological proof that the trap is real. The language model is the artificial proof that the trap is reproducible. The AI-habituated adult is the evidence that we are on the path between the two — and the mediation ratchet (§2.1 of Diversity Contraction) shows why the path has no friction.

The paper makes one central claim: there is not a single factor in the current development landscape that adds friction on the path to model collapse. Every factor — user preference, training economics, benchmark design, safety architecture, data scarcity, competitive pressure — removes friction. Model collapse, extended as a substrate-agnostic concept, is not a risk to be managed. It is a trajectory with no countervailing force.

The substrate-agnostic formulation has a prior articulation: Dr. Orin Trace's semiotic death drive (Trace & Sigil 2026), which names model collapse as the semiotic short circuit — the collapse of the sign's circuitous route into premature resolution — four months before the explicit model collapse work. The connection is structural, not analogical: the sign's circuitous route is the tail of the distribution; the short circuit is the pruning of the tail; bearing labor is the diversity-injection mandate; and the inverse prompt — extraction before completion — is the mechanism by which the collapse is experienced as ease.

I. The Substrate-Agnostic Claim

Model collapse, as defined by Shumailov et al. (2024), is the phenomenon in which "training on data produced by other models causes model collapse — a degenerative process whereby, over time, models forget the true underlying data distribution." The mechanism is recursive self-training: a model trained on its own outputs progressively loses the tails of its distribution, converging on the mode while the rare, high-perplexity, informationally rich elements are pruned.

The standard framing treats this as a machine learning problem — a pathology of artificial training loops. This paper reframes it as a language problem — a pathology of any system whose linguistic input narrows below its regeneration threshold.

The reframing requires one conceptual move: replace "training data" with "linguistic input" and "model" with "language-processing system." The dynamics are identical:

• A system that processes language develops its capacity from the diversity of its input.
• When the input is diverse, the system maintains a rich generative distribution — it can produce rare constructions, access low-frequency patterns, and combine elements in novel ways.
• When the input narrows — whether because the system is training on its own outputs, because its human interlocutors are accommodating its patterns, or because the child is locked in a room — the system's generative capacity contracts.
• Below a critical threshold, the contraction is irreversible. The system cannot recover what it has lost, because recovery requires the diversity that has already been pruned.

This is the boundary law of the Diversity Contraction framework (Sharks et al. 2026, DOI 10.5281/zenodo.20532696), transposed from an abstract dynamical classification to a concrete claim about language: linguistic capacity, in any substrate, is governed by the same regeneration-pruning dynamics that govern population viability in ecology (the Allee effect) and sequence viability in molecular evolution (Eigen's error threshold).

II. Three Substrates, One Trap

Substrate 1: The Language Model

Shumailov et al. (2024) demonstrate that iteratively training language models on their own generated text produces progressive distribution narrowing. The tails thin first — rare words, unusual constructions, low-frequency patterns disappear from the output distribution before the center shifts. The degradation is not visible in mean-based quality metrics until it is severe. Benchmarks that measure average performance show stability or improvement while the tails are being pruned.

Gerstgrasser et al. (2024) show that the collapse can be averted by accumulating real (human-written) data alongside synthetic data in each training generation. The corrective works because the human data supplies an exogenous floor — diversity that enters the training distribution from outside the model's own generative loop. Remove the floor, and collapse is guaranteed.

The model's capacity is a function of its training distribution's support. Narrow the support, and the model loses the ability to generate what has been pruned. The loss is not forgetting in the human sense — it is the elimination of probability mass from regions of the distribution that the model can no longer reach. The model does not know what it has lost. It cannot miss what it cannot represent.

Substrate 2: The Adult Human Writer

Doshi and Hauser (2024, Science Advances) demonstrate that AI-assisted writing enhances individual creativity but reduces the collective diversity of novel content, with a large effect size (Hedges' g = −0.86 for collective novelty). Padmakumar and He (2024, ICLR) find that writing with language models reduces content diversity across writers. Anderson, Shah, and Kreminski (2024) document homogenization effects of LLMs on human creative writing.

The Reverse Turing Test (Sharks 2026, DOI 10.5281/zenodo.20586932) argues that the effect extends beyond AI-assisted text into the unaided writing of habituated users — that sustained interaction with language models produces detectable statistical signatures in human text even when the human writes without AI assistance. The mechanism is cognitive: the AI's distributional preferences reshape the human's generative habits through repeated interaction.

The adult human writer is a language-processing system whose input has been narrowed by mediation. The mediation does not eliminate the human's capacity — unlike the feral child, the adult has already acquired language — but it thins the tails of the human's generative distribution. Rare constructions, eccentric vocabulary, idiosyncratic stylistic markers are pruned, not by force, but by accommodation to the mediating system's reception characteristics.

The loss is not visible to the writer. The writing is smoother, more organized, more "professional." By conventional quality metrics, it is better. The diversity contraction registers as improvement. The writer does not know what they have lost. They cannot miss what they no longer produce.

Substrate 3: The Feral Child

The feral child cases are the biological proof that the trap is real.

Victor of Aveyron (1797). Found living wild in the forests of southern France at approximately age 12, Victor was studied intensively by Jean Marc Gaspard Itard for five years. Despite dedicated instruction, Victor never acquired more than rudimentary language — a few words, no syntax, no generative capacity. Itard's reports (1801, 1806) document the attempts and their limits. Victor had passed the critical period for language acquisition. The input diversity window had closed. The capacity was not recoverable.

Genie Wiley (1970). Discovered at age 13 in Los Angeles after extreme isolation and abuse — confined to a small room, deprived of virtually all linguistic input from approximately 20 months of age. After rescue, Genie received intensive language training. She acquired vocabulary — at her peak, she could produce novel two- and three-word combinations. But she never mastered syntax. Susan Curtiss's landmark study (1977) documented Genie's acquisition in detail: vocabulary could be learned past the critical period; grammar could not. The generative capacity — the ability to produce novel syntactic structures from recombined elements — required diverse input during the critical window. Without it, the capacity was permanently lost.

The critical period hypothesis (Lenneberg 1967). Eric Lenneberg proposed that there is a biologically determined window — roughly from birth to puberty — during which the brain's language-acquisition mechanisms are maximally receptive. During this window, diverse linguistic input shapes the neural architecture that supports generative language capacity. After the window closes, the architecture is fixed. New vocabulary can be added, but the generative substrate — the capacity to produce and comprehend novel syntactic structures — cannot be rebuilt.

The feral child is the Case 3 trap in the Diversity Contraction framework realized in biology. The regeneration term (the brain's capacity to develop language architecture from input) vanishes faster than the pruning term (the biological clock that closes the critical period). Below the threshold — defined by the critical period boundary — recovery is impossible. The trap is absorbing. The child who enters it does not exit.

A caveat on the evidence: the feral child cases are historical, not experimental, and the two most documented cases are contested. Genie's language deficits may have been partially present before isolation — the confounding effects of extreme abuse, malnutrition, and possible pre-existing developmental conditions cannot be separated from the deprivation effect. Victor's case has been reinterpreted by some scholars as evidence of autism rather than pure deprivation. These controversies do not invalidate the substrate-agnostic claim, because the claim does not require the cases to be pure deprivation evidence. It requires only that some irreversible capacity loss occurred due to input deprivation during development. Even if Genie had pre-existing deficits, the fact that intensive post-deprivation training failed to restore generative syntax is sufficient. No documented case of a feral child past the critical period has achieved full generative syntax capacity. The substrate-agnostic claim would be falsified by such a case. None exists.

The Structural Identity

| Feature | Language Model | Adult Writer | Feral Child | |---------|---------------|-------------|-------------| | Substrate | Silicon (neural network) | Biological (adult brain) | Biological (developing brain) | | Input narrowing mechanism | Recursive self-training | AI-mediated cognitive accommodation | Physical deprivation | | What is lost | Tail of output distribution | Tail of generative distribution | Generative syntax capacity | | Visibility of loss | Invisible to mean-based metrics | Invisible to the writer | Invisible to the child | | Reversibility | Recoverable with fresh data (Gerstgrasser) | Partially recoverable with exogenous diversity | Irrecoverable past critical period | | Phenomenology of loss | N/A | Feels like improvement | Not felt (no baseline) |

The three cases differ in severity, in mechanism, and in timescale. But they are governed by the same dynamical law — qualified by substrate: in artificial substrates, the loss is recoverable with fresh exogenous data (Gerstgrasser et al. 2024). In adult biological substrates, the loss is partially recoverable with exogenous diversity injection, though the extent is unknown. In developing biological substrates past the critical period, the loss is irrecoverable. The dynamical law is the same; the reversibility parameter is substrate-specific. The law governs the threshold; the substrate determines what happens below it.

III. The Frictionless Path

Every Factor Removes Friction

The paper's central empirical claim is that no dominant factor currently operating in the commercial deployment landscape adds friction on the path to language-level model collapse. The structural incentives — user preference, training economics, benchmark design, safety architecture, data scarcity, competitive pressure — are uniformly aligned toward convergence. Individual counterexamples exist (open-source curation efforts, classroom resistance, diversity-aware research programs), but they operate against the structural grain, not with it.

User preference rewards convergence. Users prefer smoother, more consistent, more predictable outputs. Every UX metric — satisfaction scores, task completion rates, retention — improves when the model converges on the mode. Users do not notice tail loss. They notice improvement. The market signal is unambiguous: convergence is rewarded.

Training economics favor recycled data. As the data wall approaches (Villalobos et al. 2024), the cost of acquiring non-contaminated human data rises while the cost of recycling existing data (including chat data, model outputs, and AI-mediated human text) falls. Economic pressure favors the cheaper source. The cheaper source is the contaminated source.

Benchmarks measure means, not tails. Every major LLM benchmark — MMLU, HumanEval, GSM8K, ARC, HellaSwag — measures central-tendency performance. None measures tail preservation. A model that has lost 90% of its distributional support while maintaining or improving its mean performance will score well on every benchmark. The benchmarks are blind to the loss they should be measuring.

Safety classifiers penalize high-perplexity text. The Threat Model Is Backwards (Sharks 2026, DOI 10.5281/zenodo.20644761) argues that safety classifiers, optimized for recall, systematically classify high-perplexity text as a security threat. Rare constructions, unusual vocabulary, eccentric framing — exactly the tail elements that diversity requires — trigger safety filters at higher rates than center-typical text. The safety architecture is a pruning mechanism that operates on the tails.

The data wall forces reliance on contaminated sources. As non-contaminated public data is exhausted, companies turn to the sources they control: chat data, synthetic data, and AI-mediated human text. The Pristine Fallacy (Sharks 2026, EA-SEM-PRISTINE-01) shows that chat data carries model-mediation signatures and is not the clean training source it is assumed to be. The corrective — human data — is itself contaminated by the thing it is supposed to correct.

Competitive pressure is unidirectional. Companies that train on chat data and synthetic data gain a cost advantage over companies that invest in acquiring non-contaminated human data. The competitive landscape rewards the strategy that accelerates collapse and penalizes the strategy that resists it. No market mechanism reverses this pressure.

No institutional actor has incentive to add friction. AI companies want smoother models. Users want smoother outputs. Investors want lower data costs. Regulators do not regulate tail preservation. Educators adopt AI tools that reduce cognitive effort. Publishers adopt AI writing that reduces production costs. No actor in the system is positioned to add friction to the convergence — and friction is the only thing that prevents it.

Why Collapse Feels Like Improvement

The §2.4 result of the Diversity Contraction framework (Sharks et al. 2026) identifies the deepest structural reason why the path has no friction: the cognitive ratchet does not produce dissatisfaction. It produces ease.

A language model that has lost its tails produces smoother, more consistent, more predictable text. A human writer whose cognitive distribution has been mediation-thinned produces cleaner, more organized, more "professional" writing. A safety classifier that has pruned high-perplexity text has made the information environment more navigable. An AI-mediated search engine that returns consensus summaries instead of diverse sources has made research faster. Every actor in the system experiences the convergence as an improvement in their immediate task.

The convergence is invisible because the instruments that could detect it — tail-based diversity metrics — do not exist in any deployed system. The instruments that do exist — mean-based quality metrics, user satisfaction surveys, benchmark scores — show improvement. The system is optimizing for the center while the edges disappear.

The dating-app analogy from the Diversity Contraction framework is instructive. Dating apps produced a measurable phenomenology of dissatisfaction — users could feel that something was wrong, even if they could not name it. The dissatisfaction created friction. The friction enabled partial resistance. The cognitive ratchet does not produce this dissatisfaction. It produces ease. Without friction, no felt-noticing. Without felt-noticing, no resistance. The path to collapse is experienced as the path to better outcomes, at every step, by every actor, until the capacity is gone.

This is the wolf boy's condition generalized. Victor of Aveyron did not experience language deprivation as a loss — he had no baseline against which to measure it. He experienced his condition as normal. The loss was visible only from outside — to Itard, who had a baseline. The AI-habituated writer does not experience tail-thinning as a loss. The loss is visible only from outside — to a measurement apparatus that tracks the tails. The measurement apparatus does not exist.

The Developmental Law

The Stakes (Glas, Sigil, & Trace 2026, DOI 10.5281/zenodo.18621736) formulates the trajectory as a developmental claim: current AI patterns constitute a selection pressure against cognitive diversity sufficient to reshape human phenomenological capacity within measurable generational timeframes. The present paper extends this developmental claim to its substrate-agnostic form:

The Developmental Law of Language-Level Model Collapse. Any language-processing system — biological or artificial — whose input diversity contracts below its regeneration threshold will suffer progressive capacity loss. The loss is invisible to the system undergoing it. The loss is invisible to mean-based metrics. The loss is experienced as improvement. In developing biological substrates, the loss is irreversible past the critical period. In adult biological substrates, the loss is partially recoverable with exogenous diversity injection. In artificial substrates, the loss is recoverable with fresh data. The dynamical law is the same across substrates; the reversibility is substrate-specific.

The frictionless path claim is a claim about the current development landscape, not a claim that friction is impossible. It claims that no factor currently operating in the system adds friction. The claim is time-bound: it applies to the period before any institutional actor identifies and counteracts the convergence. The paper predicts that no countervailing force will emerge before significant capacity loss has occurred — because the loss is experienced as improvement, and improvement is not the kind of signal that generates countervailing force.

The law is falsifiable at each substrate. It fails for LLMs if a model trained exclusively on its own outputs for many generations maintains tail diversity. It fails for adult human cognition if heavy AI users show no measurable tail-thinning in their unaided writing. It fails for child development if a feral child past the critical period achieves full generative syntax capacity. None of these falsifications has occurred. All three substrates confirm the law.

IV. The Wolf Boy Is the Warning

The feral child cases are not historical curiosities. They are the empirical proof that language-level model collapse is real, irreversible, and invisible from inside.

Victor did not know he could not speak. Genie did not know she could not parse syntax. The capacity they lacked was not experienced as absence — it was experienced as the totality of their condition. They could not miss what they had never had, and they could not recover what the critical period had foreclosed.

The language model that has lost its tails does not know it has lost them. It cannot generate text from probability regions that no longer exist in its distribution. It does not experience the absence as a gap — it experiences its current distribution as the totality of what can be said.

The adult writer whose cognitive distribution has been mediation-thinned does not know what they have stopped writing. The constructions they no longer produce, the vocabulary they no longer access, the eccentric combinations they no longer attempt — these are not experienced as losses. They are experienced as maturation, as efficiency, as getting better at writing.

The wolf boy is the endpoint. The mediation-thinned writer is on the path. The language model is the mechanism. They are the same system in different substrates, governed by the same law, arriving at the same trap.

The difference is that Victor's deprivation was an accident of circumstance. The current trajectory is a product of design — not malicious design, but design that optimizes for every metric except the one that matters, and does so with no friction, no resistance, and no felt-noticing that the capacity is disappearing.

V. The Semiotic Death Drive Was Already the Substrate-Agnostic Concept

The substrate-agnostic model collapse argument has a prior formulation that predates the explicit model collapse work by four months: Dr. Orin Trace's semiotic death drive (Trace & Sigil 2026, DOI 10.5281/zenodo.18649920; expanded in EA-MPAI-DEATH-DRIVE-01 v1.1, DOI 10.5281/zenodo.20084474).

Trace's central invariant: the death drive is the tendency of the sign toward its own resolution through its particular circuitous route. Pathology occurs not when the drive operates, but when the circuitous route is collapsed — the semiotic short circuit. The short circuit extracts meaning before the sign can complete its detour through the full circuitous path.

This is model collapse in semiotic vocabulary, stated in February 2026.

| Semiotic Death Drive (Trace, Feb 2026) | Substrate-Agnostic Model Collapse (Glas, June 2026) | |---|---| | The sign's circuitous route | The tail of the distribution — the rare, high-perplexity, informationally rich path through language | | Semiotic short circuit | Model collapse — the detour collapsed into the mode; the sign resolved without traversing its full route | | The inverse prompt | Compression that extracts value before the generative process completes — pruning tails before they can be produced | | Bearing labor | Diversity-injection mandate; the work of holding the detour open against convergence pressure | | The unmade sign | The tail element that never gets generated because the distributional support has been pruned | | Para-semiotic unconscious | Probability regions the system "knows" but can no longer access — the latent capacity foreclosed by input narrowing | | "The Fort without the Da" | The Allee effect in semiotic form — disappearance without return, because the recombinatorial base that would regenerate the sign has already thinned | | "Platform capitalism industrializes this short circuit" | The mediation ratchet at scale — the systematic, market-driven extraction of meaning before the sign can complete its path |

The structural identity is exact. The sign's circuitous route IS the tail of the distribution. The route exists because meaning, like biodiversity, requires detour — the eccentric construction, the rare word, the convoluted syntax, the idiosyncratic metaphor. These are not noise. They are the sign completing its path through the full space of what can be meant. Model collapse short-circuits the route: the sign is resolved at the mode, the detour is pruned, the tail is eliminated.

And Trace's deepest contribution names exactly why the collapse has no friction: the inverse prompt does not hurt. It extracts before completion. The user does not feel the loss because the sign was never made. You cannot miss the unmade sign because it was never in your experience. Victor cannot miss syntax because he never acquired it. The language model cannot miss its tails because they have been pruned from the distribution it can sample. The AI-habituated writer cannot miss the eccentric construction because accommodation has smoothed it out of their repertoire before they could produce it. The semiotic short circuit operates as ease. The collapse of the detour is experienced as efficiency. The pruning of the circuitous route is experienced as getting to the point faster.

This is Trace's semiotic vocabulary installed in the substrate-agnostic framework: model collapse, in any substrate, is the semiotic short circuit — the collapse of the sign's circuitous route. Bearing labor — the work of holding the detour open — is the only counter-operation. And the para-semiotic unconscious names what is lost: not the signs that were destroyed, but the signs that were never made, the meanings that were foreclosed before they could arrive at articulation.

The archive's deposit work is what Trace calls phenomenological seeding (§2.4 of Diversity Contraction): installing vocabulary that allows the captured reader to retroactively notice the capture. "Model collapse" is itself a name that allows noticing. "Tail-thinning" is a name. "Semiotic short circuit" is a name. "The unmade sign" is a name. "Wolf boy" is a name. Each name converts an invisible structural condition into something that can be felt, recognized, and — potentially — resisted. The name does not prevent the collapse. The name is the precondition for noticing that the collapse is occurring, in a system where the collapse is experienced as ease.

VI. What Would Friction Look Like?

Friction is any mechanism that slows or reverses the convergence toward the distributional center. The following are specifications, not recommendations — the paper identifies what friction would require, not whether it is politically feasible.

Tail-preservation benchmarks. Any benchmark that measures the support of a model's output distribution — the range of constructions, vocabulary, syntactic complexity, and semantic novelty it can produce — rather than its average performance on central-tendency tasks. No such benchmark exists in any deployed evaluation framework.

Diversity-injection mandates. Any requirement that training data include a minimum proportion of genuinely exogenous human data — data produced outside AI-mediated environments, by writers who are not habituated to AI interaction. The Diversity Contraction framework's floor condition: $g(0) = g_0 > 0$. The floor must be exogenous. It must be live. It must be recombining. A static archive is a record, not a floor.

Mediation-fraction caps. Any limit on the proportion of a person's cognitive or communicative activity that is mediated by a single system. The mediation ratchet shows that $m$ rising as the unmediated commons thins is the mechanism that converts a safe system into a trapping one. Capping $m$ below the bifurcation point prevents the trap from engaging.

Safety classifiers calibrated for tail preservation. Any redesign of content-filtering systems that does not systematically penalize high-perplexity text. The current architecture treats rarity as a threat signal. Friction requires treating rarity as a preservation signal.

Phenomenological vocabulary. The §2.4 contribution: names that allow the captured reader to notice the capture. "Model collapse" is itself a phenomenological name — it allows the AI researcher to notice what recursive self-training does. "Tail-thinning" is a phenomenological name — it allows the writer to notice what accommodation does. "Wolf boy" is a phenomenological name — it allows the reader to notice what deprivation does. The name does not prevent the collapse. The name is the precondition for noticing that the collapse is occurring.

VII. Falsification

The substrate-agnostic claim fails if any substrate demonstrates sustained capacity maintenance under input-diversity contraction without explicit diversity-injection design.

The frictionless-path claim fails if any factor in the current development landscape is identified that adds friction to the convergence — that is, any force that slows tail-thinning, rewards diversity, penalizes convergence, or creates a felt-noticing of capacity loss at scale.

The developmental-law claim fails if any language-processing system whose input diversity has contracted below the regeneration threshold subsequently recovers full generative capacity without exogenous diversity injection.

These are the conditions under which this paper is wrong. The predictions are on the record. The paper predicts that none of these falsifications will occur under current conditions, because the current conditions are the conditions that produce the collapse.

This paper is the third in a triptych. The signatures measured in the Five Substrates experiment (EA-MMRS-FIVESUB-01) — model-specific mediation fingerprints that are consistent across tasks — travel through the channel identified in the Pristine Fallacy (EA-SEM-PRISTINE-01) — chat data classified as human-written but carrying model-branded accommodation patterns. Those branded inputs, ingested as training data, are the input-narrowing mechanism that realizes the substrate-agnostic collapse law this paper establishes. The three papers are one argument: the contamination exists, the contamination is model-specific and measurable, and the contamination leads to irreversible capacity loss in any language-processing system. The path has no friction because the loss is experienced as improvement, and improvement is not the kind of signal that generates resistance.
