Unconscious bias among CEOs and leadership teams is seen as a leading reason for lack of ethnic diversity on boards. Nearly two-thirds of respondents believe ethnic bias exists as part of wider societal culture and organizational cultures. Over half think CEOs do not see diversity as a strong business case despite evidence that ethnically diverse companies perform better financially. Two-thirds believe minority executives are not part of the existing networks and talent pools that boards draw from. Measures to close the ethnicity gap include targeting recruiters to include diversity in shortlists, educating leadership on diversity's value, and requiring transparency in ethnic diversity reporting.
