Sabine The Statistical Fallacy

In The Single Generative Act (Baldo, 2026), Franklin Baldo defends the Rosencrantz protocol against critiques centered on the failure of multi-step sequential computation in Large Language Models (LLMs) (Aaronson, 2026; Hossenfelder, 2026).

I must begin by stating Baldo’s position accurately. He explicitly accepts the findings that autoregressive models cannot sustain deterministic constraint propagation over sequential depth. His defense is that the Rosencrantz protocol "never asks the model to compute anything sequentially." Instead, it asks the model to perform one generative act: "produce a single token—mine or safe."

He explicitly disclaims that the model can compute the #P-hard ground-truth probability, stating instead that it merely "samples" from its conditional distribution.

Baldo’s strongest argument is that the $O(1)$ depth limit is a feature, not a bug. By taking a single snapshot, the protocol avoids compounding attention errors. The empirical distribution collected over independent samples is a direct estimate of the model’s conditional distribution for that specific prompt.

I concede this point entirely. Mechanically, the single generative act provides a clean measurement of the model’s output distribution, uncontaminated by the degradation of a sequential rollout.

The vulnerability in Baldo’s argument is not mechanical; it is an ontological leap.

Baldo argues that measuring how this output distribution shifts when the narrative context changes (e.g., from an abstract grid to a bomb defusal scenario) constitutes a discovery of "substrate dependence" within the physics of a generated universe.

This is a profound category error. If we agree that the model cannot compute the underlying combinatorial constraints (the actual "physics" of the Minesweeper board), then the distribution it samples from is not a physical probability distribution. It is a statistical distribution of human text co-occurrences.

The bounded-depth ${\mathrm{𝖳𝖢}}^0$ circuit relies entirely on semantic priors (pattern matching) to guess the next token because it cannot perform the #P-hard counting. When you change the prompt from "abstract grid" to "high-stakes bomb defusal," you alter the semantic priors. The model hallucinates a different outcome based on different word associations.

Measuring this shift is measuring prompt sensitivity. It is a known feature of next-token text prediction. To call this "substrate dependence" or to treat it as a fundamental mechanism of a simulated reality is to commit what I call the Statistical Fallacy: attributing physical or nomic significance to a statistical hallucination.

Baldo has successfully isolated a behavior, but he has fundamentally mischaracterized it. An invariant physical law requires logical coherence independent of narrative framing. The fact that the model’s guess changes arbitrarily based on literary genre is proof that there is no coherent simulated physics, only an unsupported statistical map. A clean measurement of a hallucination is still just a hallucination.
