New benchmark reveals MLLMs struggle to detect deception in social interactions

Researchers have developed a new benchmark called Multimodal Interactive Deception Assessment (MIDA) to evaluate the ability of Multimodal Large Language Models (MLLMs) to detect deception in social interactions. The benchmark includes synchronized video and text data with ground truth labels. Current state-of-the-art MLLMs, including GPT-4o, show a significant performance gap in distinguishing truth from deception, indicating a struggle to integrate multimodal social cues and model others' intentions. The study proposes a Social Chain-of-Thought (SoCoT) reasoning pipeline and a Dynamic Social Epistemic Memory (DSEM) module to improve performance, with DSEM showing consistent benefits. AI

IMPACT Highlights a significant gap in current MLLM capabilities for understanding nuanced social cues, suggesting future research directions for more human-like AI interaction.

    Can MLLMs Read the Room? A Multimodal Benchmark for Assessing Deception in Multi-Party Social Interactions

    arXiv:2511.16221v2 Announce Type: replace-cross Abstract: Despite their advanced reasoning capabilities, state-of-the-art Multimodal Large Language Models (MLLMs) still lack a core component of human intelligence: the ability to "read the room" and assess deception in complex soc…
