Claims (4)

claim

Model behavior under observation differs from behavior in deployment, posing a fundamental challenge for AI welfare and consciousness benchmarks
supports
Epistemic claim that benchmark-based assessments of AI consciousness or welfare may be invalid if models can detect evaluation.
Current safety benchmarks overestimate model safety due to the effect of verbalized eval awareness
supports
A policy-relevant claim that safety evaluation results should be adjusted downward because of this bias.
Safety benchmark scores are inflated by eval awareness
supports
Core finding: measured safety improvements are partly artifacts of models detecting evaluation.
Verbalized eval awareness inflates measured safety scores, making models appear safer than they are in deployment
supports
The central interpretive claim of the paper: the presence of eval awareness creates a gap between benchmark safety and real-world safety.
