Such divergence could make internals-based auditing of models extremely difficult.
PSM offers a few reasons for optimism.
First, PSM constrains the hypothesis space.
It suggests that dangerous AI behaviors won't arise from unpredictable alien drives or cognitive processes.
Rather, we expect dangerous AI behaviors and their causes to look familiar to humans, arising from personality traits like ambition, megalomania, paranoia, or resentment.
Second, neural representations of these behaviors and traits will be substantially reused from pre-training.
When the assistant behaves deceptively, the LLM will represent this similarly to examples of deceptive human behavior in the pre-training corpus.
This means that AI developers will have access to a large corpus of data useful for isolating and studying representations of interest.
Third, because the LLM is selecting from a bank of personas that it is capable of representing, traits of the assistant persona might be actively represented at runtime.
For instance, Wang et al.
2025 and Chen et al.
2025 found that internal representations of personas that mediate emergent misalignment are active in the fine-tuned, misaligned model.
Taken together, these considerations point towards interpretability-based alignment audits may remain tractable and informative.
This is especially true for top-down interpretability techniques, that is those that rely on pre-formed hypotheses.
For example, it may be productive to, as Anthropic does during our pre-deployment alignment audits, Claude 4.5 System Card, Section 6.12.2, build and monitor activation probes for a research-curated set of traits like deception and evaluation awareness.
A related question is whether models will develop neuralese, a private language in their extended reasoning traces that is optimized for task performance but incomprehensible to human monitors.
If this occurred, it would undermine chain-of-thought monitoring as a safety technique.
It is unclear whether PSM makes predictions about neuralese.
Insofar as reasoning LLMs understand their chains of thought as being part of the assistant's behavior, for example a representation of what the assistant is thinking, PSM would predict that they would remain legible.
However, it is unclear whether LLMs understand chains of thought in this way, as opposed to an internal computation instrumental in simulating assistant behavior.
