Behavior is Not Enough: A Mechanism-Based Evaluation of Social Norm Emergence in LLM Societies
Rasika Muralidharan, Haewoon Kwak, Jisun An
Social norms cannot be identified from behavior alone: the same cooperative equilibrium may reflect shared expectations, strategic incentives, or simple imitation. Yet in multi-age…
PluRule: A Benchmark for Moderating Pluralistic Communities on Social Media
Zoher Kachwala, Bao Tran Truong, Rasika Muralidharan +3
Social media are shifting towards pluralism -- community-governed platforms where groups define their own norms. What violates rules in one community may be perfectly acceptable in…
CogBias: Measuring and Mitigating Cognitive Bias in Large Language Models

Understanding Moral Reasoning Trajectories in Large Language Models: Toward Probing-Based Explainability
Fan Huang, Haewoon Kwak, Jisun An
Large language models (LLMs) increasingly participate in morally sensitive decision-making, yet how they organize ethical frameworks across reasoning steps remains underexplored. W…
LLMs Can Infer Political Alignment from Online Conversations
Byunghwee Lee, Sangyeon Kim, Filippo Menczer +3
Due to the correlational structure in our traits such as identities, cultures, and political attitudes, seemingly innocuous preferences like following a band or using a specific sl…
XChoice: Explainable Evaluation of AI-Human Alignment in LLM-based Constrained Choice Decision Making
Weihong Qi, Fan Huang, Rasika Muralidharan +2
We present XChoice, an explainable framework for evaluating AI-human alignment in constrained decision making. Moving beyond outcome agreement such as accuracy and F1 score, XChoic…
Vulnerability of LLMs' Stated Beliefs? LLMs Belief Resistance Check Through Strategic Persuasive Conversation Interventions
Fan Huang, Haewoon Kwak, Jisun An
Large Language Models (LLMs) are increasingly employed in various question-answering tasks. However, recent studies showcase that LLMs are susceptible to persuasion and could adopt…
What Helps Language Models Predict Human Beliefs: Demographics or Prior Stances?
Joseph Malone, Rachith Aiyappa, Byunghwee Lee +3
Beliefs shape how people reason, communicate, and behave. Rather than existing in isolation, they exhibit a rich correlational structure--some connected through logical dependencie…
Can Lessons From Human Teams Be Applied to Multi-Agent Systems? The Role of Structure, Diversity, and Interaction Dynamics
Rasika Muralidharan, Haewoon Kwak, Jisun An
Multi-Agent Systems (MAS) with Large Language Model (LLM)-powered agents are gaining attention, yet fewer studies explore their team dynamics. Inspired by human team science, we pr…
Gendered Cultural Discourse in Japan across the Prewar-Postwar Transition: Evidence from Historical Word Embeddings
Shintaro Sakai, Haewoon Kwak, Jisun An +1
We quantify the evolution of gender stereotypes in Japan from 1900 to 1998, covering the prewar-postwar transition, using a series of yearly word embeddings trained on historical t…
Cognitive Linguistic Identity Fusion Score (CLIFS): A Scalable Cognition-Informed Approach to Quantifying Identity Fusion from Text
Devin R. Wright, Jisun An, Yong-Yeol Ahn
