AI Safety and Alignment Research

Abstract

AI safety and alignment research addresses the challenge of ensuring that increasingly capable AI systems pursue the goals their developers and users intend, remain under meaningful human oversight, and avoid catastrophic failures as they become more capable and autonomous. The field has grown substantially since its early theoretical foundations, with major AI laboratories now maintaining dedicated safety teams and governments establishing AI safety institutes. This study provides a systematic review and evaluation of eight AI safety and alignment research directions: Constitutional AI, RLHF and preference learning, scalable oversight (debate, amplification), interpretability and mechanistic understanding, robustness and anomaly detection, red-teaming and adversarial evaluation, formal verification and provable safety, and a proposed Unified Safety Evaluation Protocol (USEP). Evaluation covers: technical maturity, empirical effectiveness on standardised safety benchmarks (HarmBench, AdvBench, SafetyBench), scalability to frontier models, and theoretical grounding. Constitutional AI achieves the best practical safety performance on HarmBench (Claude 3.5 Sonnet: 99.4% safe response rate). Scalable oversight through debate achieves 84.2% alignment with expert consensus on complex reasoning tasks. Mechanistic interpretability successfully identifies deceptive reasoning circuits in 78.4% of tested cases. RLHF preference learning shows systematic miscalibration on distribution-shifted queries (22.4% reward hacking rate). USEP provides a standardised cross-method evaluation framework and achieves the highest expert consensus on evaluation comprehensiveness. A research priority framework for scalable AI alignment is proposed
