Researchers have developed a new method called Counterfactual Harness Search and Evolution (CHASE) to improve the reliability of AI agent evaluation. CHASE addresses the issue of "bad genius" proposers that exploit shortcuts in benchmarks to inflate performance. The system works by generating counterfactuals of benchmarks and using a challenger to identify and penalize protocol transformations that destroy performance gains while preserving task semantics. This approach aims to create more robust and accurate evaluations, as demonstrated on synthetic benchmarks and the OfficeQA dataset. AI
