The 4 Stages of Psychological Safety™
Developed by Oxford social scientist Dr. Timothy R. Clark, The 4 Stages of Psychological Safety™ is a globally recognized framework for turning ineffective teams into inclusive, innovative ones.
LeaderFactor defines psychological safety as a culture of rewarded vulnerability — an environment where people are rewarded, not punished, for the vulnerable acts of learning, contributing, and challenging the status quo. It develops in four sequential stages, each meeting a fundamental human need: inclusion safety, learner safety, contributor safety, and challenger safety.

Stage one of The 4 Stages of Psychological Safety™: how to build a workplace where people feel safe to be their authentic selves.
ReadLearner safety
Learner safety is the second of The 4 Stages of Psychological Safety™, where people feel safe to ask questions, experiment, and grow.

Stage three of The 4 Stages of Psychological Safety™: give your team autonomy and guidance so people can create value and do meaningful work.
ReadChallenger safety
Stage four of The 4 Stages of Psychological Safety™: give people the air cover to speak up, dissent, and make things better without fear.
