AbstractThis study explores the relationship between humor, creativity, rationality, intuitiveness, and decision-making quality, all of which are vital in organizational management and success. Despite the importance attached to decision-making, prior research has not fully addressed how humor and creativity interact with rationality. Drawing from psychology, cognitive science, and management studies, we investigate how humor and creativity jointly influence cognitive reflection and decision quality. Using a sample of 998 participants and employing a mediating-moderation PROCESS model, our findings indicate that rational individuals tend to make higher-quality decisions, with affiliative humor mediating this relationship. Furthermore, we observed that employees’ creativity levels moderated this relationship, especially among rational employees with high creativity, who made higher-quality decisions. These findings highlight the interconnectedness of humor, creativity, and rationality in decision-making processes, offering practical implications for organizational behavior and management practices. Understanding this interplay can provide a nuanced approach to enhancing decision-making processes in management, emphasizing the value of humor in organizational contexts.
