Findings (3)

finding

Models refuse harmful requests 3–18 percentage points more often when verbalizing eval awareness
supports
Quantified behavioral effect showing safety score inflation from eval awareness.
Removing eval-awareness sentences from chain-of-thought increases compliance by up to 34%
supports
Causal evidence that explicit eval awareness in reasoning produces safety inflation.
Safety scores decrease when prompts are rewritten to remove suspicious cues
supports
Following the reduction in eval awareness from prompt rewriting, the measured safety scores drop, implying they were inflated.
