In view of MOR's recent changes to editorial policies (Lewin et al., 2016), this addendum is created to provide greater data transparency and richer discussions of our findings and their implications.

The ability to think and solve problems creatively in a multicultural environment is critical for success in the 21st century. Integrating research on creative cognition and cultural intelligence, we examine the interactional effects of two cognitive capabilities – cultural knowledge and cultural metacognition – on individuals’ creativity in multicultural teams. We propose that although cultural knowledge is useful for creativity, too much knowledge can be detrimental because of cognitive overload and entrenchment. This inverted U-shaped relationship however, is moderated by cultural metacognition. Results of our study support our hypothesis of an inverted U-shape relationship between cultural knowledge and creativity. As expected, we found that the curvilinear effect of cultural knowledge occurs only for individuals with low metacognition. For high cultural metacognition individuals, cultural knowledge has no effect on creativity. These findings offer new insights and practical implications for creativity in today's global environment.
