Unveiling the Nuances of AI in Social Simulation
Evaluating LLM-Simulated Conversations in Modeling Inconsistent and Uncollaborative Behaviors in Human Social Interaction
Simulating human conversations using large language models (LLMs) has recently emerged as a scalable methodology for modeling human social interaction. However, simulating human conversations is challenging because they inherently involve inconsistent and uncollaborative behaviors, such as misunderstandings and interruptions. Analysis comparing inconsistent and uncollaborative behaviors in human- and LLM-generated conversations remains limited, although reproducing these behaviors is integral to simulating human-like and complex social interaction.
Executive Impact
Our analysis uncovers critical disparities between human and LLM conversational dynamics, with significant implications for AI-driven social simulations.

COCOEVAL is an evaluation framework analyzing inconsistent and uncollaborative behaviors in LLM-simulated conversations. It features a fine-grained evaluation at the turn level, detecting 10 types of behaviors, complementing coarse-grained LLM-as-a-Judge scores. The framework also includes COCOEVAL-BENCH, a benchmark of real-world human conversations across various domains.
The study evaluates LLMs under various simulation settings: Vanilla Prompting for baseline comparison, Taxonomy-Guided Prompting which explicitly instructs LLMs to incorporate specific inconsistent and uncollaborative behaviors, and Supervised Fine-Tuning (SFT) on human conversations. It also examines the impact of generating multiple turns per LLM call (1, 5, or 30 turns) versus single-turn generation.
Key findings indicate that vanilla prompting leads to significantly fewer inconsistent and uncollaborative behaviors in LLMs compared to humans. Prompt engineering (taxonomy-guided) does not reliably control these behaviors, sometimes leading to overproduction. Supervised fine-tuning can result in LLMs overproducing a narrow set of behaviors like repetition. Lastly, generating multiple turns per LLM call strongly influences the types and frequencies of these behaviors.

Significant Observation
88% Reduction in Inconsistent/Uncollaborative Behaviors (Vanilla LLMs)Case Study: Unnatural Repetition from SFT
Table 4 in the paper illustrates how GPT-4.1, when fine-tuned on human conversations and generating one turn per call, exhibits unnatural repetitive utterances. Speakers like 'Manager' and 'Interface' repeatedly agree with simple 'Exactly,' 'Yeah,' 'Right,' 'Perfect,' and 'Alright,' which is not human-like. This highlights a critical challenge: SFT can lead LLMs to overproduce a narrow set of behaviors, deviating from diverse human interaction patterns.
