Imagine a workplace where people hesitate to speak up. Questions go unasked, mistakes get buried, and ideas never see the light of day—all because employees fear embarrassment or repercussion.
Now imagine the opposite. A culture where people feel safe to take risks, admit missteps, and challenge the status quo. That difference is called psychological safety—and it’s the hidden engine behind the highest-performing teams.
What Is Psychological Safety?
The term was pioneered by Amy Edmondson, a professor of leadership and management at Harvard. She’s spent decades researching what makes some teams thrive while others struggle, and her work consistently points to one factor: whether people feel safe to speak up.
Psychological safety doesn’t mean being “nice” or avoiding hard conversations. Instead, it means creating an environment where:
- People can ask questions without being judged.
- Admitting a mistake isn’t a career risk—it’s a learning opportunity.
- Healthy debate is welcomed, not punished.
Edmondson’s research shows that teams with high psychological safety learn faster, innovate more, and perform better—because no one is holding back.
Why It Matters
Without psychological safety, organizations fall into silence:
❌ Problems stay hidden until they explode.
❌ Meetings become echo chambers.
❌ Employees disengage, fearing that speaking up will backfire.
With psychological safety, you get the opposite:
✅ Diverse perspectives surface.
✅ Small problems get addressed early.
✅ People feel ownership of their work and commitment to the team.
It’s not just a feel-good idea—it’s a performance driver. Google’s Project Aristotle, which studied what makes teams effective, found psychological safety was one of the most important factors in team success.
How To Build Psychological Safety on Your Team (TODAY)
Here are four simple shifts that you can make today.
- Model vulnerability: Admit when you don’t know something or when you’ve made a mistake.
- Reward candor: Thank people when they raise tough questions or challenge assumptions.
- Create structure: Use check-ins or team agreements to make space for every voice in the room.
- Create a feedback culture: Encourage everyone to give and receive feedback and to treat it like a valuable opportunity to learn.
The Bottom Line
Great teams don’t just execute tasks—they create a culture where everyone feels safe to contribute. Psychological safety isn’t soft—it’s strategic. And as Amy Edmondson’s & Google’s research shows, it may be the most important investment you can make as a leader.
