Cultural diversity is a defining feature of the modern global business environment, requiring leaders to engage effectively across cultures with skill, insight, and adaptability. This chapter explores cultural metacognition, a core element of cultural intelligence (CQ), as an essential tool for leading in multicultural contexts. Cultural metacognition refers to the awareness and adjustment of one’s thought processes in response to cultural differences, enabling leaders to make informed decisions and build meaningful relationships across diverse cultural settings. Through an interdisciplinary study combining global leadership and cross-cultural psychology, the chapter draws on in-depth interviews with bicultural global leaders. These leaders shared personal experiences and strategies for adapting their approaches to effectively manage cultural diversity. The research highlights how cultural metacognition enhances leadership by allowing leaders to anticipate cultural differences, shift leadership styles to suit specific contexts, and foster inclusive teamwork that respects varied perspectives. The findings demonstrate how cultural metacognition strengthens collaboration, resolves misunderstandings, and promotes mutual trust in culturally diverse teams. In the context of “Modern Cross-Cultural Management” this chapter provides practical and actionable insights into the importance of cultural metacognition as a leadership skill. It illustrates how this competence empowers leaders to navigate cultural complexities, achieve organizational goals, and inspire collaboration in culturally varied settings. By equipping readers with these strategies, the chapter serves as a valuable resource for understanding and embracing the power of cultural intelligence in today’s interconnected world.
