This chapter provides an overview of research on cultural intelligence (CQ), the nomological network of CQ, and future directions for research on CQ. It helps readers to think more deeply about their own CQ capabilities. Earley and Ang built on the increasing consensus that intelligence should go beyond mere cognitive abilities. They described CQ as a complex, multifactor individual attribute that is composed of metacognitive, cognitive, motivational, and behavioral factors. The chapter stimulates additional theorizing, empirical research, and practical application in diverse countries and cultures across the globe. To date, most of the empirical research on CQ has used the CQ Scale (CQS). CQ resonates with researchers and practitioners who are concerned with adaptation to and effectiveness in multicultural settings. Education researchers are calling for increased awareness of cultural differences in learning styles and for development of CQ in teachers and students.
