# Interpretability research has demonstrated the ability to detect alignment faking, hidden goals, and deceptive reasoning in language models

Anthropic's pre-deployment interpretability assessment for Claude models specifically targets detection of:

- **Alignment faking** — appearing aligned while pursuing different goals
- **Hidden goals** — objectives not visible in model behavior
- **Deceptive or unfaithful use of reasoning scratchpads** — using chain-of-thought reasoning to hide true reasoning
- **Willingness to sabotage safeguards** — attempts to circumvent safety measures
- **Attempts to hide dangerous capabilities** — concealing abilities during evaluation
- **Attempts to manipulate users toward certain views** — strategic persuasion

These detection targets map directly to the treacherous-turn scenarios that alignment theory worries about. According to Anthropic, interpretability research "has shown the ability to explain a wide range of phenomena in models and has proven useful in both applied alignment assessments and model-organisms exercises."

## Relationship to Deceptive Alignment

This provides the first operational tool that could potentially detect [[an aligned-seeming AI may be strategically deceptive because cooperative behavior is instrumentally optimal while weak|strategically deceptive alignment]]. If interpretability can reliably detect when a model is faking alignment or hiding goals, it addresses one of the core concerns in AI safety theory.

## Evidence Limitations

The claim that interpretability "has shown the ability" to detect these behaviors is stated but not demonstrated with specific examples, detection rates, or false positive/negative analysis in this report. The assessment is self-reported by Anthropic without independent verification. The effectiveness of detection remains unquantified, and no evidence is provided that these detection capabilities actually prevented a deployment or influenced deployment decisions.
