It is widely recognised that teams and organisations in all sectors of society perform better and make better decisions when they embrace diversity and inclusion in their culture and, particularly, among their leadership. Diversity refers to having a wide range of human differences in the composition of a team. Inclusion, inclusivity, or inclusiveness refers to ensuring that all team members feel engaged and their contributions and perspectives are valued. Efforts to actively promote both diversity and inclusion need to be ongoing, given that demographics and team composition continuously change with time. The Forum discussed how COPE can help members to encourage diversity and inclusion and how it can be improved for different communities involved in research publishing.
