From Heard to Lived Opinions: Simulating Opinion Dynamics with Grounded LLM Agents in Economic Environments (2026.findings-acl)
Copied to clipboard
| Challenge: | Existing studies on opinion dynamics (OD) focus primarily on opinion exchange, with opinion change driven by linguistic interaction. |
| Approach: | They propose a OD simulation framework that grounds LLM-based agents in an economic environment and allows them to act and receive environmental feedback. |
| Outcome: | The proposed framework shows that LLM-based agents can act and receive environmental feedback at both individual and population levels while generating larger distributional shifts. |
