Psychological safety is a condition in which human beings feel (1) included, (2) safe to learn, (3) safe to contribute, and (4) safe to challenge the status quo – all without fear of being embarrassed, marginalized, or punished in some way. The 4 stages of psychological safety is a universal pattern that reflects the natural progression of human needs in social settings. When teams, organizations, and social units of all kinds progress through the four stages, they create deeply inclusive environments, accelerate learning, increase contribution, and stimulate innovation.
