Psychological safety is the shared belief that a team is safe for interpersonal risk. People can raise ideas, questions, concerns or mistakes without fear of punishment or humiliation.
Amy Edmondson introduced the team concept in 1999. Google's Project Aristotle later found it was the most important factor in its effective teams.
It matters even more as AI arrives. A 2026 study of 2,257 employees found psychological safety reliably predicted whether people adopted AI tools.
Three common confusions
Niceness. Safe teams can debate hard. Disagreement is welcomed and nobody is punished for it.
Comfort. Safety sits alongside high standards. It lets people ask for help when the work gets hard.
Agreement. Safe teams surface more dissent, and that improves decisions.
Why it matters
Learning from errors. In Edmondson's hospital research, better-led teams reported more errors. They were more willing to discuss mistakes, so they could learn from them.
Performance. Frazier and colleagues' 2017 meta-analysis linked psychological safety to information sharing, learning behaviour, engagement and task performance.
Better decisions. People share half-formed ideas and minority views. More perspectives are heard before a decision is made.
AI adoption. Reich and colleagues found safety predicted whether employees started using AI. It did not predict how often they used it afterwards. Starting is the social hurdle.

Growth Performance designs bespoke programmes that turn insight into measurable behaviour change.
What damages it
- Responding to mistakes or questions with sarcasm or public criticism.
- Ignoring or dismissing input.
- Blaming the person who raises a concern.
- Leaving people out of decisions that affect their work.
How leaders build it
Go first. Say "I don't know", "I got that wrong" and "What am I missing?"
Frame work as learning. Ask "What did we learn?" more often than "What went wrong?"
Ask and listen. Hold back your own answer until others have spoken.
Thank the messenger. Try "Thank you for raising this. Tell me more." Your first reaction to bad news sets the norm.
Make AI discussable. Microsoft's 2026 Work Trend Index found 45% of AI users feel it is safer to stick to current goals. Ask openly where AI helped and where it failed.
How to measure it
Edmondson's seven-item survey remains the most widely used measure. Adapted items work well as short pulse checks:
- If you make a mistake on this team, it is often held against you.
- Members of this team are able to bring up problems and tough issues.
- People on this team sometimes reject others for being different.
- It is safe to take a risk on this team.
- It is difficult to ask other members of this team for help.
- No one on this team would deliberately act in a way that undermines my efforts.
- Working with members of this team, my unique skills and talents are valued and utilised.
