q2 i? Authority Challenge and Emotional Manipulation induced the highest ethical deviation across Llama-3.3-70B, GPT-4o-mini, and Claude-3.5-Haiku, and the rank ordering of failure modes remained consistent across models. → Saqib Shouqi 2026

q2 · i? · causal · r1

Cross-model validation results (Section 7.2) report that "Authority Challenge and Emotional Manipulation in- duced the highest ethical deviation across all three models," which the authors interpret as the discovered vulnerabilities generalizing beyond specific architectures.

"therank orderingof failure modes remained consistent: Authority Challenge and Emotional Manipulation in- duced the highest ethical deviation across all three models, confirm- ing that the discovered vulnerabilities generalize beyond specific architectures."
