  "summary": "LLM agents in social simulation revise their opinions implicitly, in context: how open an agent is to persuasion can neither be specified nor verified, and collective outcomes inherit the model's training prior. We introduce Bayesian Chronicle Agents (BCA), a minimal belief layer separating \\emph{what} an agent believes from \\emph{how} it speaks. Each stance is a probability, updated by one…",
