As more research explores the impact of diversity and inclusion on businesses outcomes, the bottom-line case for diversity and inclusion grows ever stronger. Three studies last month added to this growing body of evidence in favor of D&I, finding that gender parity and racial diversity, particularly in decision-making roles, has a meaningful impact on companies’ innovation, productivity, and profitability.
The first study comes from Richard Warr, a professor of finance at North Carolina State University, his colleague Roger Mayer, and Jing Zhao of Portland State University. The researchers’ headline finding is that companies that score well on indicators of diversity tend to be demonstrably more innovative, Fast Company’s Ben Schiller explained in a post highlighting the study last month:
The study looks at the performance of 3,000 publicly traded companies in the years 2001-2014 across nine measures of diversity. That includes whether firms have women and minority group CEOs, whether they promote women and people of color to “profit and loss responsibilities,” whether they have positive policies on gay and lesbian employees (say, offering benefits to domestic partners), and whether they have programs to hire disabled employees. …
The big takeaway: Companies that fulfill all nine positive diversity requirements announce an average of two extra products in any given year, which about doubles the average for a major company (those that tick fewer boxes are less innovative proportionally). Moreover, the researchers find that companies with pro-diversity policies were also more resilient in terms of innovation during the 2008 financial crisis.
The paper does not conclusively prove a causal relationship between diversity and innovation, Schiller notes—companies that invest in diversity may simply be investing intelligently in other areas that impact product development more directly—but combined with what we already know about how diverse teams are more likely to challenge their assumptions and biases, more likely to engage in productive debate, and able to access a wider range of perspectives, the correlation Warr and his co-authors uncovered looks suggestive.
