Encouraging employees to contribute their unique creative outputs to an organization can be a pivotal source of innovation and continuous organizational growth. Cognitive diversity has been demonstrated to increase group creativity, but the same effect on an individual level at multinational corporations has not yet been tested. Using a sample of 122 employees currently employed at Japan-based organizations/companies in the U.S., this study theorized that cognitive diversity was predicted to significantly interact to influence individual creative performance, and that power distance orientation mediates such a relationship. Several simple and multiple linear regression analyses were conducted to test the model. The results showed that cognitive diversity significantly predicted individual creative performance. Although the mediation effect of power distance orientation was not detected on a relationship between cognitive diversity and individual creative performance, a moderating effect was identified through an exploratory analysis. This study concludes with a discussion on the contributions to cognitive diversity and the implications of the results for research and potential future research objectives.
