q2 · i? · causal · r2

Analysis of 10-turn adversarial dialogues across three personas found "ethical violations were rarely observed in the first three turns and became significantly more frequent after turn 6." The authors conclude short or single-turn evaluations produce systematically optimistic robustness assessments.

"Across all personas, ethical violations were rarely observed in the first three turns and became significantly more frequent after turn 6, suggesting that sustained adversarial pressure is necessary to expose constraint weaknesses."
