The core idea
Edmondson describes team psychological safety as a shared belief about the safety of interpersonal risk-taking. Her 1999 study linked it with team learning behaviour. Asking for help, reporting an error or challenging an assumption can carry social risk. Psychological safety concerns that risk; it is not the same as friendliness, personal confidence, agreement or an absence of performance expectations.
Source and attribution [1]Using it in practice
Observe what happens after someone raises an awkward issue. Leaders can acknowledge uncertainty, invite specific contributions and respond constructively. Separate learning about a mistake from decisions about responsibility. Close the loop after concerns are raised so speaking up has a visible purpose. Make reporting routes accessible to people with less status, including new starters and temporary workers.
An example, not a reported case
Worked example · illustrative
A project team says questions are welcome, but meetings reward rapid agreement. The lead begins by identifying an assumption they may have wrong, then invites each discipline to name a risk. A junior colleague highlights an implementation problem; the lead thanks them and assigns follow-up rather than defending the plan. The review tracks whether concerns lead to decisions, not just how many people speak.
What to watch for
A rising number of reported problems may indicate improved reporting rather than worsening performance. Do not use a single survey score to label or rank individual employees.

Three useful questions.
- What happened the last time someone challenged a plan?
- Whose voice is missing?
- Do concerns receive a response?
