Abstract Many organizations are committed to age diversity and inclusion, aiming for a fair treatment and balanced representation of younger and older employees in all units of the organization. However, the continuing workplace discrimination against mature workers demonstrates that older employees are often excluded and remain underrepresented. Hence, organizations still struggle to reach their diversity goals and finding ways to effectively foster employee behaviors that result in more age diversity is therefore crucial. We investigate the impact of age diversity statements on selecting older and younger individuals into teams in 3 experimental studies. We find consistent evidence that when building teams, short diversity statements increase the selection rates of older individuals so that teams become more age balanced. With no age diversity statement in place, older teammates are hardly chosen, showing that diversity statements can help overcome negative age bias. We found no evidence that age diversity statements produce unintended negative side-effects in terms of increased bias based on dimensions other than age. Overall, this research provides a first examination and encouraging conclusions regarding the effectiveness of age diversity statements, laying the groundwork for more field research in this area.
