Judging the Judges: Measuring Bias in AI Risk Assessment

08.02.2026 by Ray Dalio

Large language models demonstrate a nuanced capacity to assess merchant category code risk, consistently categorizing low-risk examples like grocery stores while exhibiting predictable discrepancies at category boundaries-discrepancies quantified by unified risk scores derived from global payment data encompassing fraud, chargebacks, and operational factors-and thereby revealing a gradient of risk assessment aligned with real-world payment dynamics.

As large language models increasingly take on evaluative roles, understanding their inherent biases becomes crucial for reliable decision-making.

Beyond the Benchmark: Building Truly Secure AI-Generated Code

07.02.2026 by Ray Dalio

The proposed framework embodies an acceptance of inevitable systemic decline, prioritizing graceful degradation over indefinite preservation-a recognition that all structures, however robust, exist within the medium of time rather than resisting it.

New research reveals that current methods for evaluating the security of code created by artificial intelligence are often misleading, and proposes a more robust, human-guided approach.

Picking the Right Attack: How AI Control Systems Can Be Subverted

07.02.2026 by Ray Dalio

The attack selection framework demonstrably reduces safety metrics compared to established baselines-specifically the ‘always attack’ and ‘vibes’ approaches-as evidenced by performance gains achieved with both the rubric prompt and the GEPA-optimized prompt.

New research reveals that strategically selecting adversarial prompts can dramatically compromise the safety of AI control protocols, even when paired with trusted monitoring.
