A Persona-Based Evaluation Framework for Pluralistic Alignment in Generative AI
This work addresses the problem of accurately evaluating generative AI for diverse human perspectives, which is crucial for developing more context-sensitive and human-aligned AI systems.
This paper introduces a persona-based evaluation framework for generative AI to address the limitation of monolithic benchmarking that obscures human judgment plurality. They show that modern generative architectures can instantiate and maintain diverse evaluative personas with high consistency, but these simulated evaluators degrade in coherence under sequential inference and stochastic prompt perturbations.
Current alignment paradigms for generative artificial intelligence rely predominantly on monolithic benchmarking frameworks that reduce the plurality of human judgment to aggregated statistical baselines, thereby obscuring cultural, demographic, and contextual variability in evaluation. We introduce a state-space constrained emulation framework for AI evaluation that replaces singular assessment functions with a structured manifold of synthetic cognitive profiles representing diverse human perspectives. We show that modern generative architectures can instantiate and maintain these evaluative personas with high consistency, enabling a form of pluralistic, perspective-dependent benchmarking that more closely reflects real-world consensus variability. However, we further analyze the stability of these simulated evaluators under sequential inference and stochastic prompt perturbations, revealing systematic degradation in persona coherence that manifests as state-space drift and semantic inconsistency. These findings suggest that static alignment constraints are insufficient for sustaining robust evaluative behavior over time. Instead, we argue for the necessity of embedding dynamic, viability-driven regulatory mechanisms within generative systems to preserve coherent cognitive emulation. By framing persona-based evaluation as a structured dynamical system over latent representation manifolds, this study provides a foundation for more adaptive, human-aligned, and context-sensitive approaches to AI evaluation.
