Psychological safety is the shared belief held by members of a team that the team is safe for interpersonal risk-taking, and that members can challenge, question and disagree without suffering consequences to their image, reputation or career. The term stems from the work by Schein (1992) and was investigated in teams by Amy Edmondson of Harvard in the late 1990s (Edmondson, 1999). Psychological safety research pulls together several insights about team effectiveness, resilience and organizational learning. As you will likely surmise by the end of this chapter, a climate of psychological safety is critical for building a restorative just culture.
