Tippins et al. (2023) challenge I-O psychologists to more actively – in Miller’s oft-quoted APA presidential address – “give psychology away.” Their article provides stirring examples of the impact several of our colleagues have made in giving psychology away. In thinking about how to encourage and facilitate more of us to volunteer, we’d like to share several thoughts on our roles as I-Os, both as individuals and as a community. In particular, we propose that volunteerism is an expression of our calling as I-Os; suggest five roles we can play as individuals; discuss three roles for the community at-large; and conclude with a call to action.
