This paper systematically reviews and synthesizes domestic and international research on the impact of uncertainty on conformity behavior, exploring the mechanisms and pathways through which uncertainty influences conformity. The paper begins by analyzing the concept and measurement of uncertainty, followed by a discussion of the definition and measurement methods of conformity behavior. By integrating findings from existing research, it further examines how uncertainty affects the manifestation and intensity of conformity through various mechanisms. Specifically, the review highlights the role of uncertainty in enhancing group identification and promoting adherence to behavioral norms in ambiguous situations. Finally, the paper identifies gaps in the current research, suggesting that future studies should focus on clarifying the types of uncertainty, conducting cross-context comparative studies, and investigating the dynamic processes through which uncertainty influences conformity behavior.
