Forskning om kvinnor i styrelser är inte speicellt omfattande men jag har upptäckt ett projekt där man studerat förhållandet mellan antalet kvinnor och män i styrelser. Forskningen "Critical Mass on Corporate Boards: Why Three or More Women Enhance Governance, Sumro Erkut, Ph.D"

har kommit fram till följande slutsatser:

"Women bring a collaborative leadership style that benefits boardroom dynamics by increasing the amount of listening, social support, and winwin problem-solving"

 ” Women also bring new issues and perspectives to the table, broadening the content of boardroom discussions to include the perspectives of multiple stakeholders. Women of color add perspectives that broaden boardroom discussions even further.

"One woman serving on a board can make a positive contribution. Having two women is generally an improvement, but corporations with three or more women on their boards tend to benefit most from women’s contributions. Three women normalize women directors’ presence, allowing women to speak and contribute more freely and men to listen with more open minds. As one woman director we interviewed summarized it, “One woman is the invisibility phase; two women is the conspiracy phase; three women is mainstream.”
