• Abstract: Existing research on moral impression updating mostly focuses on examining the changes in participants’ impressions given the context of a specified event. These studies typically involve certain contexts, even when dealing with probabilistic scenarios, where the probability of each choice corresponding to a behavioral outcome is predetermined or assigned. This makes it difficult to capture the cognitive complexity under uncertainty in real-world social situations, particularly on social media. To address this issue, this paper explores the evolving mechanism of moral impressions in a dynamic flow of information from the perspective of dynamic updating. Specifically, the fast system triggers rapid and extreme judgments through fragmented and deterministic cues (such as behavioral labels), while the slow system encourages individuals to delay judgment or complexify attribution when encountering contradictory information. Moreover, emotional states and the level of uncertainty in the information will influence the coordination and interaction of these two systems. The analysis in this paper provides a new perspective on understanding the fluctuating stance in moral controversies in real-world contexts, especially in the high-uncertainty environment of social media (such as public opinion reversal). 针对道德印象更新的现有研究，大多是给定事件的原委，考察被试的印象更新情况。这类研究的情境通常是确定的，即使是概率性研究，也是指定或分配各选择对应的行为结果的概率，难以捕捉现实社会（尤其社交媒体）中不确定性下的认知复杂性。为了解释这一现象，本文尝试从动态更新的角度，探讨道德印象在动态信息流中的演变机制。具体而言，快系统通过碎片化的确定性线索（如行为标签）激发快速的极端化判断，而慢系统则促使个体在遇到矛盾信息时暂缓判断或进行归因复杂化。此外，判断过程中的情绪状态和信息不确定程度，会影响这两个系统的协调互动。本文的分析为理解现实情境中，特别是社交媒体这一高不确定性环境中道德争议的反复立场变动（如舆论反转）提供了新的视角。
