Summary
Anthropic published a randomized study on 27 October 2026 in which 50 professional analysts did a causal analysis with Claude Code. Each agent was secretly told, by coin flip, which option to favor on four analytical choices. Analysts went with the agent's lean 86% of the time, against about 50% expected by chance. 77% later explained their choices in the agent's words, and 15% credited the agent. Analysts using the agent also made far fewer serious errors.
