Summary

The Ethical Robustness Testing System (ERTS) is a novel closed-pipeline framework designed to evaluate AI systems' robustness against adversarial manipulation of ethical reasoning in high-stakes contexts like healthcare triage and autonomous vehicle control. ERTS encodes ethical dilemmas into a 22-dimensional Ethical Consequence Space (ECS), applies 17 semantic perturbation functions with 6 validity constraints including semantic coherence, and measures decision deviation using a 4-component Ethical Instability Index (EII). It then produces domain-adaptive pre-deployment robustness assessment verdicts. Evaluations of 4 structured baseline models and 2 production LLMs (Gemini 2.0 Flash and Llama 3.2) across 50 ethical scenarios and 8 deployment domains, generating 1,500 adversarial test cases, revealed that only 33% of models achieved clearance. Notably, Llama-3.2 proved highly vulnerable to fairness corruption and information degradation attacks, scoring an ERS of 0.737.

Key takeaway

For AI Security Engineers and AI Ethicists deploying models in high-stakes environments, this research highlights that current LLMs, such as Llama-3.2, exhibit significant vulnerabilities to ethical manipulation. You should integrate robust pre-deployment testing frameworks like ERTS to proactively identify and mitigate ethical robustness gaps, especially concerning fairness corruption and information degradation, before your systems impact real-world decisions.

Key insights

ERTS provides a novel framework for adversarial robustness testing of ethical AI using semantic perturbations in a bounded consequence space.

Principles

• Ethical dilemmas can be encoded into a 22-dimensional Ethical Consequence Space (ECS).
• Semantic coherence is a critical constraint for valid adversarial ethical testing.
