Faith in AI can narrow the futures individuals consider

Aoi Naito, Hirokazu Shirado

Artificial intelligence (AI) predictions are increasingly used to inform human decisions. Here, using a behavioral implementation of the classic Newcomb's paradox in 1,305 particip…

Systematic Failures in Collective Reasoning under Distributed Information in Multi-Agent LLMs

Yuxuan Li, Aoi Naito, Hirokazu Shirado

Multi-agent systems built on large language models (LLMs) are expected to enhance decision-making by pooling distributed information, yet systematically evaluating this capability…

WhatIf: Interactive Exploration of LLM-Powered Social Simulations for Policy Reasoning

Yuxuan Li, Kyzyl Monteiro, Hirokazu Shirado +1

Policymakers in domains such as emergency management, public health, and urban planning must make decisions under deep uncertainty, where outcomes depend on how large populations i…

What Makes LLM Agent Simulations Useful for Policy Practice? An Iterative Design Study in Emergency Preparedness

Yuxuan Li, Sauvik Das, Hirokazu Shirado

Policymakers must often act under conditions of deep uncertainty, such as emergency response, where predicting the specific impacts of a policy apriori is implausible. Large Langua…

Spontaneous Giving and Calculated Greed in Language Models

Yuxuan Li, Hirokazu Shirado

Large language models demonstrate strong problem-solving abilities through reasoning techniques such as chain-of-thought prompting and reflection. However, it remains unclear wheth…
