A Leader’s Role in Improving Psychological Safety: Building Trust, Openness, and Growth

Introduction

Psychological safety is not something you can install like software. It’s grown, moment by moment, through interactions that either build or break trust. And leaders are at the centre of that process.

Research shows that leaders influence whether people speak up, admit mistakes, challenge ideas, or hide their concerns. In psychologically safe teams, people feel they can take interpersonal risks without fear of embarrassment, rejection, or punishment.

Unfortunately, most leaders overestimate how safe their teams feel. We’ve worked with senior leaders who are genuinely surprised when anonymous feedback reveals that their teams don’t feel comfortable raising concerns. Intent and impact are often miles apart. This is one of the reasons anonymous diagnostic tools are so helpful for leaders and teams.

This post explores how leaders create and reinforce psychological safety, and how small, intentional changes in behaviour can transform team culture.

Why Leadership Matters Most

Leaders set the tone. Whether you’re a line manager or a CEO, your behaviour creates powerful cues:

• Do you welcome disagreement?
• Do you show humility?
• Do you follow through on promises?
• Do people feel seen and heard?

Even unspoken signals, raised eyebrows, rushed meetings, or silence in response to input, send messages about what’s safe and what’s not. People are remarkably good at reading these cues (even when leaders think they’re hiding them).

In short: what you tolerate, celebrate, and model becomes the team norm.

Key Leadership Behaviours That Build Psychological Safety

1. Admit Fallibility

Say things like:

“I might be missing something—what’s your take?”

This normalises uncertainty and invites contribution. It sounds simple, but in our experience, very few leaders do this consistently. Many worry it will undermine their authority. In practice, it does the opposite.

2. Ask Better Questions

Open-ended questions signal interest and openness:

“What concerns do you have?” | “What’s one thing I could do differently to support you?”

3. Respond With Curiosity, Not Judgment

When people raise issues, your reaction is everything. A curious, calm response builds trust, even if the feedback is tough.

“Thanks for sharing that. Can you tell me more?”

Compare that with a defensive response or a dismissive sigh. One builds safety. The other destroys it. And the team is always watching.

4. Model Vulnerability

Share your own learning moments or growth edges. This encourages others to be real too.

“That meeting didn’t go how I hoped. I’m still learning how to handle tough questions.”

5. Recognise Contributions, Not Just Outcomes

Praise effort, ideas, and speaking up, not just results. This reduces fear of “getting it wrong.”

6. Build Inclusive Norms

Actively involve quieter voices. Rotate who speaks first. Signal that all perspectives matter.

“Let’s hear from someone who hasn’t spoken yet.”

From Individual to Culture

It’s not just about “being nice.” Leaders must set expectations, hold people accountable, and address unhelpful behaviors, but in ways that preserve dignity and openness.

Can you hold someone accountable while still making them feel respected? That’s the real skill here. And it’s not easy.

When leaders:

• Challenge with compassion
• Debrief openly after failure
• Make space for difference, and
• Share credit generously

… they build teams where candour, learning, and resilience thrive.

We’ve seen this play out many times. Leaders who combine high expectations with genuine warmth tend to build the strongest teams. Leaders who are warm but avoid challenge tend to build comfortable teams that underperform. And leaders who are demanding but cold? They get short-term results, at least until their best people burn out or leave.

From Reactive to Proactive

Building safety also means looking ahead:

• Before meetings – Set norms: “All voices welcome.”
• During delivery – Normalise updates and learning, not just results.
• After feedback – Say thank you. Follow up. Change behaviour.
• In conflict – Slow down. Listen more. Own your part.

Safety doesn’t mean no discomfort. It means people trust the discomfort will be held well. And that trust is earned through repeated, consistent action over time, not through a single team offsite or a well-worded email (however well-intentioned).

The People Shift View

At PeopleShift, we believe psychological safety is about the most important factor for teams. It’s a core of a lot of what we do in our work with teams and leaders. It links to lots of other topics we think matter too, like emotional intelligence, self-awareness, service, and so on.
