• Abstract: Does moral belief convergence in deliberation stem from public compliance or deep private acceptance? Distinguishing these two qualitatively different forms of change at the neural level is crucial to understanding its mechanism. This paper reviews the behavioral and neural foundations of moral belief convergence, and identifies three key challenges confronting current research: a lack of dynamic neural evidence from naturalistic interactions, the persistent disconnection between cognitive and affective processing pathways, and the difficulty of differentiating the two modes of convergence using behavioral indicators alone. We propose a neural model framework centered on functional near-infrared spectroscopy (fNIRS) hyperscanning. In genuine deliberation, enhanced interpersonal neural synchronization (INS) in the dorsolateral prefrontal cortex (dlPFC) and the left inferior frontal gyrus (IFG) may reflect deep belief restructuring, whereas in pseudo-deliberation, single-brain activation patterns in the ventromedial prefrontal cortex (vmPFC) and the right IFG may be more indicative of surface compliance. We further propose that the ratio of dlPFC INS to right IFG INS could serve as a potential neural marker for distinguishing the quality of the two types of convergence. This work offers new insights for evaluating the trustworthiness of deliberation, optimizing democratic deliberation mechanisms, and improving public communication strategies from a neuroscientific perspective. 协商中道德信念的趋同，究竟来自公共服从还是深层的私人接受？从神经层面分辨这两种不同性质的改变，是理解其机制的一个关键。本文梳理了道德信念趋同的行为与神经基础，指出现有研究面临三个主要难题：缺乏自然互动中的动态神经证据，认知与情感两条加工路径彼此割裂，以及行为指标很难独自区分上述两种趋同模式。我们提出一个以功能性近红外光谱超扫描为核心的神经模型框架。在真实协商中，背外侧前额叶的脑间同步以及左侧额下回的脑间同步均增强，可能反映了深层的信念重构；而在虚假协商中，腹内侧前额叶和右侧额下回的单脑激活模式，则可能更多指向表面顺从。我们进一步提出，背外侧前额叶脑间同步与右侧额下回脑间同步的比值可以作为区分两类趋同质量的潜在神经标记，从而为从神经科学视角评估协商的可信度、优化民主协商机制及改进公共沟通策略，提供了新的思路。
