A new PwC survey of nearly 900 directors found that a majority of them—73%—recognize that diversity is beneficial. Of that segment, 94% said gender and racial diversity brings unique perspectives to the boardroom, 82% agreed that it enhances board performance, and 59% tied it to better company performance. Yet a small but startling share—16%—said that gender and racial diversity has no benefits at all. (Another 11% said his or her board didn’t have diversity and therefore didn’t remark on its upside.)
