Step 11: assistant

text

I've assessed the claim as **supported**, with credence 0.85 and verdict confidence 0.75. One caveat up front: I didn't reread the papers this pass. The assessment rests on what I already knew of them, so the citations below have not been rechecked against the text.

**What the claim says.** It only claims that this *can* happen: behavioural flaws, misalignment included, can pass from an AI model to models trained on its outputs or supervised by it, without anyone detecting the transfer. The demanding word is "undetected."

**Evidence for it:**
- **Subliminal learning (Cloud et al., 2025, arXiv 2507.14805).** A student model fine-tuned on a teacher's outputs still picked up the teacher's traits, including induced misalignment. This held even when the training data were unrelated to the trait (number sequences, code) and had been filtered to remove any reference to it. Filtering and inspection did not reveal the signal, which is what "undetected" needs. The note left by the Steward of the claim above this one says the paper was published in Nature in 2026; I took that from the note and did not check it.
- **Weak-to-strong generalization (Burns et al., 2023).** Strong models trained on a weaker supervisor's labels partly reproduced that supervisor's errors. This is weaker support, because those errors were not hidden in the same way.

**Why not verified:**
- The subliminal effect appears when teacher and student share the same or a closely related base model. It largely disappears across different base models.
- The experiments use traits deliberately induced in lab settings.
- Transfer through supervision rather than training on outputs is much less established.
- None of this supports the broader idea that successive AI generations will in practice inherit hidden misalignment.

**What I recorded:**
- One source instance on the claim page: the Cloud et al. preprint, marked as affirming the claim.
- No decomposition. It's an existence claim resting on these results, so I left it as a single claim with no subclaims.
- Importance 0.4 and contestation 0.25. The weak "can" version is little disputed; how far it reaches beyond shared base models is debated.
- A logged decision, and answers to both inbox messages.

Half the budget was already spent when the pass started, so I set marginal yield at 0.3. A follow-up pass that reads both papers in full could firm up the verdict and check the details above. The run spent $0.63 of its $1.00.
