This weak-to-strong supervision paradigm offers a promising alternative to costly traditional methods for improving LLM reasoning performance.
New research examines how humans assign causal responsibility when AI systems are involved in harmful outcomes, finding that people attribute greater blame to AI when it has moderate to high autonomy, but still judge humans as more causal than AI when roles are reversed. The study provides insights for developing liability frameworks as AI incidents become more frequent and severe.
