The 4 Stages of Psychological Safety

A framework focused on human needs.

The 4 Stages of Psychological Safety framework acknowledges that we’re humans first and employees second. It follows a universal pattern that reflects the natural progression of human needs in social settings.

  1. Inclusion safety: stage of the 4 Stages of Psychological Safety framework
    01

    Inclusion safety

    Can I be my authentic self?

    Inclusion safety satisfies the basic human need to connect and belong. In this stage worth precedes worthiness. All you have to do to qualify for inclusion safety is be human and harmless.

  2. Learner safety: stage of the 4 Stages of Psychological Safety framework
    02

    Learner safety

    Can I grow?

    Learner safety satisfies the basic human need to learn and grow. In this stage, fear is detached from mistakes, and mistakes are rewarded as part of the learning process. To qualify for learner safety you must engage in the learning process.

  3. Contributor safety: stage of the 4 Stages of Psychological Safety framework
    03

    Contributor safety

    Can I create value?

    Contributor safety satisfies the basic human need to make a difference and offer meaningful contributions. When we create contributor safety for others, we empower them with autonomy, guidance, and encouragement in exchange for effort and results.

  4. Challenger safety: stage of the 4 Stages of Psychological Safety framework
    04

    Challenger safety

    Can I be candid about change?

    Challenger safety satisfies the basic human need to make things better. When we create challenger safety, we give air cover (protection) in exchange for candor.
