Psychological Safety

What is psychological safety?

Psychological safety is the shared belief within a team that it is safe to take interpersonal risks: to ask a question, admit a mistake, raise a concern, or offer a half-formed idea without fear of being embarrassed or punished. The concept was defined and popularised by Harvard professor Amy Edmondson.

It is a property of the team and its climate, not of any one person. Where it is high, people speak up; where it is low, they stay quiet to protect themselves, and the organisation loses the information it most needs.

Why psychological safety matters

Teams learn, innovate, and catch problems early only when people are willing to speak candidly. Psychological safety is consistently linked to team learning and performance, and it became widely known after Google’s research into what made its most effective teams work. It also underpins honest feedback, healthy conflict, and inclusion, since people from underrepresented groups often carry a higher cost for speaking up.

How to build psychological safety

Model fallibility. Leaders who admit their own mistakes give everyone else permission to do the same.
Respond well to bad news. How a leader reacts the first time someone raises a problem sets the tone for months.
Invite input explicitly. Ask genuine questions and reward the act of speaking up, not just the right answer.
Separate safety from standards. Safety is about candour, not lowering the bar. High-performing teams pair high safety with high accountability.

Building it is largely a leadership behaviour, which is why it connects so directly to manager effectiveness and to feedback practices such as radical candor.

Example

In a project retro, a junior engineer admits he missed a warning sign before an outage. Instead of blame, the manager thanks him for surfacing it and turns the conversation to what the system should have caught. The team leaves more willing, not less, to flag risks early.

What psychological safety is not

It is not being nice all the time, avoiding hard conversations, or freedom from accountability. A psychologically safe team can disagree sharply about ideas precisely because people trust it will not become personal.

Coaching for safer, stronger teams

Psychological safety rises when leaders change how they behave in the room. Coachello’s coaching helps managers develop the self-awareness and habits, listening, responding to challenge, inviting dissent, that make their teams safe to contribute and quicker to improve.

FAQs

Who coined the term psychological safety?

Harvard Business School professor Amy Edmondson defined and popularised the modern concept through her research on team learning.

Does psychological safety mean lower standards?

No. The strongest teams combine high psychological safety with high accountability. Safety is about candour and risk-taking, not a softer performance bar.

How do you measure psychological safety?

Usually through short survey items about whether people feel able to speak up, admit mistakes, and take risks, often included in engagement or team-health surveys.
