Despite both visible (e.g., age and gender) and non- visible (e.g., attitudes and values) forms of diversity influence social interactions and performance in various social entities, researchers have focused mainly on visible forms of diversity in their studies. The present study provides a more comprehensive account of diversity in multicultural groups and organizations by taking into account a larger set of visible and non-visible attributes. The results of four studies conducted in Finland and Japan suggest that studies focusing only on visible forms of diversity do not provide a comprehensive account of diversity in various social entities.
