Revising Context, Shifting Simulated Stance: Auditing LLM-Based Stance Simulation in Online Discussions

arXiv:2606.06443v1 Announce Type: new Abstract: Large language models are increasingly used to simulate social media users and infer how individuals may respond to online discussions. However, it remains unclear whether these simulations reflect precise user-specific beliefs or whether they are highly sensitive to semantically independent changes in conversational contexts. In this work, we study counterfactual context revision as a framework for auditing LLM-based stance simulation. Given an original online conversation, we first infer a target user's stance toward a specific topic. We then a

Why this matters
Why now

The proliferation of increasingly capable large language models (LLMs) is driving research into their application for complex social simulations, including understanding online discussions and user behaviors.

Why it’s important

This research provides a framework for auditing the reliability and bias of LLM-based simulations of human behavior, which are becoming critical for social analysis, marketing, and potentially national security applications.

What changes

The ability to accurately and transparently audit LLM-based stance simulation will enhance trust and utility in these models for understanding and potentially influencing online discourse.

Second-order effects
Direct

Improved methodologies for validating the accuracy and fairness of LLM-driven social simulations will emerge.

Second

Greater confidence in simulated user behaviors could lead to expanded deployment of LLMs for policy testing and public opinion analysis.

Third

The development of robust auditing frameworks reduces the risk of malicious use or misinterpretation of LLM-generated social insights, fostering more ethical AI deployment.
