<abstract>Large Language Models (LLMs) frequently face limitations, such as judgment biases and cognitive deadlocks, in complex reasoning due to “Degradation of Thought” in self-reflection. While Multi-Agent Debate (MAD) approaches attempt to address this issue, their inherently adversarial nature suppresses diverse perspectives by overemphasizing antagonism, which results in the loss of partially valid reasoning. In this paper, we propose Multi-Agent Diverse Thinking (MADT), a novel cognitive framework that redefines multi-agent collaboration by shifting from adversarial confrontation toward constructive synergy.
