Is this the real life? Is this just fantasy? The Misleading Success of Simulating Social Interactions With LLMs

Understand

Recent advances in large language models (LLM) have enabled richer social simulations, allowing for the study of various social phenomena.

• However, most recent work has used a more omniscient perspective on these simulations (e.g., single LLM to generate all interlocutors), which is fundamentally at odds with the non-omniscient, information asymmetric interactions that involve humans and AI agents in the real world.
• To examine these differences, we develop an evaluation framework to simulate social interactions with LLMs in various settings (omniscient, non-omniscient).
• Our experiments show that LLMs perform better in unrealistic, omniscient simulation settings but struggle in ones that more accurately reflect real-world conditions with information asymmetry.
