Validation methodology for persona/profile alignment to real individuals

Develop robust calibration and validation procedures that establish and assess persona/profile alignment in LLM-based generative agents by matching agent behaviors to those of specific real individuals within the modeled situations.

Background

The paper contends that operational validity in generative ABMs often requires validating that an agent’s behavior aligns with the particular person it is intended to represent, not merely internal consistency. Achieving such alignment would likely necessitate linking to individual-level data (e.g., surveys, experiments, or digital traces) and raises methodological and ethical complexities.

Currently, most studies rely on zero-shot models and prompt personas without empirical calibration to specific individuals. The lack of established procedures for profile alignment undermines claims of realism and external validity in generative ABMs.

How to carry out such validation is however an open question, as rigorous persona alignment would require calibrating and validating against a specific individual and their actions within situation being captured by the model.

We did not evaluate the persona on a separate Norwegian sample, so we cannot rule out that the residual gap closure overstates how well nordic_b would generalise.

We mitigate this through persona grounding, anchoring each agent to a demographically calibrated profile from the Population MCP, but the gap between a prompted persona and a real person's decision process remains an open empirical question.
