In numerous studies, diversity — both inherent (e.g., race, gender) and acquired (experience, cultural background) — is associated with business success. For example, a 2009 analysis of 506 companies found that firms with more racial or gender diversity had more sales revenue, more customers, and greater profits. A 2016 analysis of more than 20,000 firms in 91 countries found that companies with more female executives were more profitable. In a 2011 study management teams exhibiting a wider range of educational and work backgrounds produced more-innovative products. These are mere correlations, but laboratory experiments have also shown the direct effect of diversity on team performance. In a 2006 study of mock juries, for example, when black people were added to the jury, white jurors processed the case facts more carefully and deliberated more effectively.
