## Summary
Boisnard argues that some LLM biases do not come only from skewed training data or from human intentions read into machines. They also arise from the technical machinery itself: tokenization, attention, statistical optimization and safety alignment. He calls these hidden determinations, which neither users nor the model can reflect on, the "algorithmic unconscious." The empirical core is a small benchmark built with a Python script. It counts input tokens for ten parallel sentences in English, Modern Standard Arabic, Darija (in Arabic script and as Arabizi) and other languages, using several tokenizer infrastructures. Arabic varieties consistently need more tokens than English. The inflation is about 1.6× with OpenAI's tokenizer and nearly 4× with Mistral's SentencePiece. The author links this over-segmentation to three further mechanisms: correlation mistaken for causation, the erasure of minority features through dimensional collapse, and normative biases from alignment. He then proposes a "technical clinic" that audits tokenization, latent-space geometry and alignment. The point is that this bias is measurable and structural, with economic and cultural costs for speakers of non-majority languages.

## Key points
- **OpenAI benchmark (tiktoken, reported as GPT-4.1):** average tokens relative to English (7.1) were:
  - MSA: 11.5 (1.62×)
  - Darija in Arabic script: 11.3 (1.59×)
  - Arabizi: 13.2 (1.86×)
- **Mistral-7B (SentencePiece) benchmark:** inflation was much larger relative to English (8.4):
  - MSA: 33.1 (3.94×)
  - Darija: 29.1 (3.46×)
  - Arabic words were sometimes split down to single characters.
- **Measurement caveat:** the OpenAI counts reflect the shared tiktoken encoding, so they describe the infrastructure's policy rather than differences between individual models.
- **Cost argument:** citing Petrov et al. (2023), the paper notes that doubled fertility can multiply training cost up to fourfold. Users also pay more context tokens for the same query.
- **Script and normalization effects:** the appendix attributes part of the inflation to script handling, normalization pipelines and orthographic conventions, not just to language. Ukrainian is singled out as a visible case.

## Interesting ideas
- Auditing a tokenizer with a fixed set of parallel sentences and comparing average token counts per language and tool gives a cheap, repeatable fairness metric. Such a metric can be tracked across versions.
- The paper separates script and normalization effects from linguistic differences. Some "language" bias is really a preprocessing artifact, so it can be fixed upstream.
- Statistical learners pick up co-occurrence rather than intervention. Causal-sounding output from a corpus-trained model is therefore a correlation unless something else grounds it.
- Majority patterns can absorb rare features through statistical preference (dimensional collapse), and averaged metrics hide this erasure.
- A "technical clinic" audits each internal layer separately (segmentation, representation geometry, alignment filters) instead of judging only final outputs.

## For Mova

How these ideas could serve Mova, our small open language model — its files, stages and tests:

- **I1** (tokens): Run the `en` tokenizer on parallel variants of the same content (British/American spelling, informal and dialectal forms, transliterated names) and flag inputs whose segmentation inflates or becomes unstable.
- **I2** (tokens): Audit normalization (Unicode quotes, dashes, diacritics in loanwords and names) separately from morphology so that tagger and lemma errors are not blamed on the wrong layer.
- **I3** (learn): Treat causal or event-order claims from LLM teacher tiers as unverified until the world model or several witness parsers agree, and add negative controls where cue words co-occur without a causal link.
- **I4** (tree): Report LAS per construction and per rare-dialect slice for the perceptron parser and gparse, not only overall, so that rare constructions are not silently traded away.
- **I5** (learn): Mirror this with per-stage evaluation suites (tokens, tree, frames, world, answer) so that a bias can be located at the step where it enters the explainable pipeline.
