The concept of cultural intelligence (CQ), introduced by Earley and Ang in 2003, has gained traction as a critical competency in globalized workplaces. Unlike emotional intelligence, which focuses on interpersonal relationships, CQ specifically addresses an individual's ability to adapt to and function effectively in culturally diverse settings. It comprises four dimensions: metacognitive, cognitive, motivational, and behavioral. Metacognitive CQ involves higher-order thinking about cultural assumptions, while cognitive CQ pertains to knowledge of cultural norms and practices. Motivational CQ reflects the drive to engage with other cultures, and behavioral CQ is the capability to exhibit appropriate verbal and nonverbal actions. Research indicates that high CQ correlates with better job performance in multicultural teams and successful cross-border negotiations. However, scholars caution that CQ is not static; it can be developed through education, immersive experiences, and reflective practice. Thus, organizations increasingly invest in CQ training to enhance their global competitiveness.
