Diverse Evidence, Better Forecasts: Multi-Agent Deliberation Under Information Asymmetry

arXiv:2607.01661v1 Announce Type: new Abstract: Multi-agent systems are increasingly used for forecasting future events, as deliberation among multiple LLMs is believed to improve reasoning and calibration. Yet existing approaches overlook a critical design choice: what information each agent receives. When all agents are given identical evidence, deliberation collapses into herding rather than genuine belief revision, leaving multi-agent systems little better than a single agent. We identify this as a fundamental gap and propose designed information asymmetry to close it: by partitioning evid

Why this matters
Why now

The proliferation of Large Language Models (LLMs) and multi-agent systems is leading to research into optimizing their performance and robustness for complex tasks like forecasting.

Why it’s important

Improving the accuracy and reliability of AI-driven forecasting systems through better multi-agent deliberation design has significant implications for decision-making in various strategic sectors.

What changes

This research suggests a shift from homogeneous information distribution to designed information asymmetry for multi-agent AI systems, aiming to mitigate 'herding' behavior and enhance genuine belief revision.
