So why is it when many people think of diversity, they think first of ethnicity and race, and then gender? Diversity is much broader. Diversity is otherness or those human qualities that are different from our own and outside the groups to which we belong, yet present in other individuals and groups. It's important to understand how these dimensions affect performance, motivation, success, and interactions with others. Institutional structures and practices that have presented barriers to some dimensions of diversity should be examined, challenged, and removed.
