Shared Nature, Unique Nurture: PRISM for Pluralistic Reasoning via In-context Structure Modeling
arXiv:2602.21317v1 Announce Type: new Abstract: Large Language Models (LLMs) are converging towards a singular Artificial Hivemind, where shared Nature (pre-training priors) result in a profound collapse of distributional diversity, limiting the distinct perspectives necessary for creative exploration and scientific discovery. To address this, we propose to equip models with inference-time Nurture (individualized epistemic trajectories) using Epistemic Evolution paradigm, progressing through explore, internalize, and express. We instantiate this via PRISM (Pluralistic Reasoning via In-context Structure Modeling), a model-agnostic system that augments LLM with dynamic On-the-fly Epistemic Graphs. On three creativity benchmarks, PRISM achieves state-of-the-art novelty and significantly expands distributional diversity. Moreover, we evaluate the real-world utility via a challenging rare-disease diagnosis benchmark. Results demonstrate that PRISM successfully uncovers correct long-tail di

To address this, we propose to equip models with inference-time Nurture (individualized epistemic trajectories) using Epistemic Evolution paradigm, progressing through explore, internalize, and express.

On three creativity benchmarks, PRISM achieves state-of-the-art novelty and significantly expands distributional diversity. Moreover, we evaluate the real-world utility via a challenging rare-disease diagnosis benchmark. Results demonstrate that PRISM successfully uncovers correct long-tail diagnoses that standard LLM miss, confirming that its divergence stems from meaningful exploration rather than incoherent noise. Overall, this work establishes a new paradigm for Pluralistic AI, moving beyond monolithic consensus toward a diverse ecosystem of unique cognitive individuals capable of collective, multi-perspective discovery.
Executive Summary
This article proposes a novel approach to mitigating the homogenization of Large Language Models (LLMs) by introducing a model-agnostic system called PRISM, which utilizes dynamic Epistemic Graphs to facilitate pluralistic reasoning. PRISM enables LLMs to explore diverse perspectives, leading to increased creativity and novel solutions on three benchmark tests. The authors also demonstrate PRISM's real-world utility in diagnosing rare diseases, showcasing its potential to uncover previously overlooked diagnoses. This work contributes to the development of Pluralistic AI, promoting a diverse ecosystem of unique cognitive individuals that can collectively drive multi-perspective discovery. The findings suggest that PRISM's divergence is not due to incoherent noise, but rather meaningful exploration.
