Psychological safety is the idea that team members can take risks, such as voicing concerns or putting forth innovative ideas, and is considered a vital part of robust safety culture.

Results suggest routine task performance increases with psychological safety only to a point, then declines. The authors describe collective accountability to offset the decline in task performance.
