A new study published on arXiv suggests that using an LLM's past responses, or behavioral history, is more effective for creating synthetic personas than relying on descriptive information about the individual. Researchers found that while LLM personas could match human aggregate response patterns, they struggled to replicate individual-level variation. However, incorporating behavioral history significantly improved the LLMs' ability to predict individual choices, restoring much of the lost variance and providing better informedness across various demographic groups.
