The critical role of psychological safety in team success

The Critical Role of Psychological Safety in Team Success

In today’s fast-paced, complex work environments, one factor stands out as a make-or-break element for team performance: psychological safety. It’s the foundation of trust, the driver of innovation, and the secret ingredient in high-functioning teams.

But what exactly is psychological safety, and why does it matter so much?

Coined by Harvard professor Amy Edmondson, psychological safety refers to “a belief that one will not be punished or humiliated for speaking up with ideas, questions, concerns, or mistakes.” It’s the confidence that your team won’t shoot the messenger, ignore dissenting voices, or mock new suggestions. Instead, it cultivates a culture where people feel safe to take risks and be themselves without fear of judgement or retribution.

The importance of psychological safety was brought into sharp focus by a ground-breaking two-year study by Google, known as Project Aristotle. In their quest to understand what makes a team successful, researchers discovered that psychological safety - not individual brilliance, technical skill, or clear goals - was the single most important factor behind high team performance.

Why Psychological Safety Matters:

1. Boosts Collaboration:
   When people feel safe, they’re more likely to share ideas, ask for help, and challenge the status quo. This openness is essential for effective collaboration.

2. Accelerates Innovation:
   Psychological safety creates space for experimentation. It invites diverse thinking and creative problem-solving, key ingredients for innovation.

3. Reduces Risk of Mistakes:
   Teams with high psychological safety surface issues earlier. They’re more willing to flag problems, own up to errors, and learn from them, which reduces costly failures.

4. Improves Wellbeing and Engagement:
   Feeling heard and valued enhances employee morale. It reduces stress and burnout while increasing motivation and commitment to shared goals.

5. Drives Inclusion:
   Psychological safety is essential for truly inclusive workplaces. It ensures that every voice, regardless of background, identity, or role, is welcomed and respected.

What Can Leaders Do to Foster It?

Creating a psychologically safe team isn’t about being nice all the time. It’s about creating an environment where candour and vulnerability are met with curiosity and support. Here’s how to begin:

• Model the behaviour: Admit when you don’t know something. Say “I was wrong.” Show that it’s okay not to have all the answers.

• Listen actively: Make space for every voice, especially quieter ones. Don’t interrupt or rush to judgement.

• Invite feedback: Ask questions like “What might I be missing?” or “Is there a different way we could approach this?”

• Normalise risk and failure: Celebrate learning from mistakes. Frame setbacks as opportunities to grow, not things to hide.

• Recognise contributions: Acknowledge effort, ideas, and courage - whether or not the idea was adopted.

The Bottom Line

Teams succeed not just because of what they know, but because of how they work together. Psychological safety turns knowledge into wisdom, ideas into action, and diverse voices into collective strength.

When people feel safe, they speak up. When they speak up, teams learn, adapt, and thrive.
