Failure, Narrative, and the Limits of Analogy

This is the section that keeps the rest of Bio Mirror honest. Human neurology and psychiatry offer a century of carefully described failure modes, and several of them resemble what language models do closely enough to be worth naming. The resemblance is a source of hypotheses and vocabulary. It is not evidence, and the entries here say so explicitly.

Structure dictates function

Two systems can fail in the same shape for different reasons. The shape is a hypothesis; the reason has to be earned.

Confabulation and the Interpreter

Humans produce fluent, sincere, false accounts to fill gaps. So do models. The behaviors rhyme; the mechanisms do not match.

Biology

The system that generates explanations is not the system that performs actions, and it does not have privileged access to its causes. It builds a plausible account from available evidence. When the true cause is …

In AI

A model asked something outside its knowledge produces the most plausible continuation, fluently and without hedging. A model asked to explain its own reasoning produces a plausible explanation that may have no relationship to the …

In Robotics

A post-hoc explanation module that narrates a controller's decisions from its inputs and outputs rather than from its internal state. Such systems produce satisfying explanations that are not causal accounts, and the failure is instructive …


Homeostasis, Sleep, and Why Grounding Matters

Biological goals bottom out in physical need. Artificial ones bottom out in a written objective, and that is the whole alignment problem in one sentence.

Biology

Homeostasis grounds motivation. An organism's goals are not arbitrary: they terminate in physical requirements for continued existence, and reward signals are ultimately calibrated against those requirements. This grounding is why an animal cannot fully game …

In AI

There is no analogue, and the absence is the most important entry in this whole section. An artificial system's objective is written by someone. Nothing anchors it to a need. Reward hacking, specification gaming, and …

In Robotics

Battery management and thermal limits are the closest thing an artificial system has to a homeostatic drive, and it is instructive how much more robust robot behavior becomes when self-preservation constraints are made explicit rather …
