The four stages of psychological safety

1. Inclusion safety: Members feel accepted as a part of the team – they’re wanted, appreciated, and don’t feel excluded from the group.

2. Learner safety: Team members are able to ask questions, experiment, make mistakes, admit when they make mistakes, and even ask for help.

3. Contributor safety: Members feel safe to offer their own ideas without fear of embarrassment or ridicule. They’re adding value to the team and making a difference.

4. Challenger safety: Group members can question others (including those in authority) and suggest significant changes to ideas, plans, or processes.
