What is Psychological Safety?

Barbra Carlisle • April 4, 2025

Psychological Safety is a root to sustainable high performing teams 

Imagine this. You’re in a leadership meeting where a crucial decision is being discussed. One of your team members has an insight that could change the direction of the conversation, but they hesitate. The moment passes, and the idea never gets shared. A missed opportunity.

If this sounds familiar, you’re not alone. Research from Gallup (2023) found that only 3 in 10 employees strongly agree that their opinions count at work. Yet, the ability to challenge, contribute, and collaborate freely is the foundation of high-performing teams.

That’s where psychological safety comes in. A concept pioneered by Amy Edmondson, psychological safety is the belief that one can speak up without fear of humiliation, rejection, or punishment. But this safety isn’t binary – it evolves through four key stages.

Each person experiences these stages differently, depending on their communication and thinking styles. Understanding this can help leaders create an environment where everyone feels safe to contribute.

The Four Stages of Psychological Safety

1. Inclusion Safety – "Do I Belong Here?"

This is the foundation of psychological safety – the need to be accepted as part of the group, regardless of differences in background, experience, or thinking style. Some people feel secure when relationships are prioritised, while others need clarity on their role in the team.

Signs of Inclusion Safety:

  • People feel comfortable sharing personal experiences.
  • Meetings feel welcoming, and all voices are acknowledged.
  • Silence is seen as thinking time, not fear.

Different Voices, Different Needs:

Some people in your team will need warmth and relational connection to feel safe while others will want clarity on expectations and structure.  Others will feel safe where there is an open, informal exchange of ideas and similarly some team members may feel safe when there is a shared vision and strategic purpose.  Those with a creative thinking preference may value space for deep thought and time to articulate ideas fully.  

Leadership Habit: Use people’s names regularly and create structured opportunities for everyone to contribute.


2. Learner Safety – "Can I Grow Here?"

Once people feel included, the next level is about learning. Do they feel safe to ask questions, make mistakes, and try new things without fear of embarrassment? Some thrive on open-ended discussions, while others need clear expectations before stepping into learning.

Signs of Learner Safety:

  • People openly ask for feedback.
  • Mistakes are seen as opportunities for growth.
  • Junior team members contribute without hesitation.

Different Voices, Different Needs:

As with inclusion safety different team members will place higher value on different aspects of learner safety.  For example:
  • some may hesitate to take risks if they feel failure might harm relationships.
  • some want clear learning pathways before stepping out of their comfort zone.
  • some learn best through interactive, social experiences.
  • some need challenging problems to solve, not just incremental learning.
  • some prefer to process information deeply before acting.

Leadership Habit: Share your own learning style and be curious as to how others prefer to learn


3. Contributor Safety – "Can I Make an Impact?"

At this stage, team members feel safe to apply their skills, express ideas, and challenge the status quo. Some prefer to refine ideas before speaking, while others think aloud and iterate in real-time.

Signs of Contributor Safety:

  • People proactively bring solutions, not just problems.
  • There’s healthy debate without defensiveness.
  • Meetings are energised – not dominated by a few voices.

Different Voices, Different Needs:

If we look at Contributor safety through the 5 Voices lens we can see that:
  • Nurturers contribute when they know their ideas will benefit people.
  • Guardians thrive when processes are followed and well-documented.
  • Connectors engage when they can see the impact on relationships and networks.
  • Pioneers bring their best when they can drive ambitious strategies forward.
  • Creatives need the freedom to explore new concepts without immediate judgment.

Leadership Habit: Respond to ideas with “Tell me more” rather than an immediate judgment.


4. Challenger Safety – "Can I Challenge Here Without Fear?"

This is the highest level of psychological safety, where people feel empowered to question assumptions, challenge leadership, and advocate for change – all without fear of retribution. Some challenge through logical reasoning, while others need time to reflect before speaking.

Signs of Challenger Safety:

  • People call out flaws in processes or leadership decisions constructively.
  • There is healthy disagreement, not just agreement for the sake of harmony.
  • The best idea wins – not the loudest voice.

Different Voices, Different Needs:

Diversity of personality preference in the team will mean that some people:
  • may challenge in a way that prioritises harmony and relationships.
  • will challenge when there’s a risk to stability or structure
  • challenge when they see an idea that could bring people together.
  • challenge by pushing bold, strategic moves.
  • challenge by offering visionary, outside-the-box thinking.

Leadership Habit: Ask “What’s the counterargument to this?” in meetings to encourage diverse viewpoints.


The Business Case for Challenger Safety

When teams operate at Challenger Safety, organisations benefit in measurable ways:
  1. Companies with high psychological safety see a 27% increase in team performance (Google, 2022).
  2. Innovation skyrockets – teams are 45% more likely to experiment and take smart risks (CIPD, 2023).
  3. Employee engagement soars – teams with high safety have 76% lower burnout rates (McKinsey, 2023).

How to Check If Your Team Has Reached Challenger Safety

Ask your team these five questions:
  1. Do you feel comfortable challenging my thinking without consequences?
  2. Do you see mistakes as learning opportunities?
  3. When you contribute ideas, do you feel heard?
  4. Have you ever held back from speaking up? If so, why?
  5. What’s one thing I could do to make you feel safer to challenge?

If the answers reveal gaps, that’s where the work begins.

Final Thought: Psychological Safety is a Leadership Choice

Psychological safety isn’t a soft skill – it’s a strategic advantage. And it starts with small, consistent actions. Leaders who nurture inclusion, learning, contribution, and challenge create teams that are not just engaged, but unstoppable.

Introduction Going down to London a couple of weeks ago I was looking forward to putting on a good podcast and ignoring everything and everyone around me. That is until a woman, Melanie, came and plonked down next to me, with her pile of papers and her phone ringing. Once she had taken the call, she smiled at me, I smiled back and this led to a 2 and half hour conversation on all things from professional development to managing long distant relationships. I got off the train more energised, connected and ready for the day than if I had stuck my headphones in. We arranged to meet for a coffee back in Liverpool. Why am I telling you this? Because in business, we often talk about the importance of networks and collaboration—but what if some of the most transformative insights come not from your inner circle, but from a stranger on a train, a chance encounter at a conference, or a casual conversation over coffee? The Research A recent UK study from the University of Essex (Sandstrom et al., 2022) showed that small talk with strangers can significantly improve mood, empathy, and creativity. More importantly, these fleeting interactions often lead to the sharing of ideas that would otherwise remain siloed. In a time when innovation and agility are everything, this matters. Another UK study by Nesta (2019) on innovation diffusion found that ideas spread faster in communities where “weak ties” are strong—those acquaintances and peripheral connections that sit just outside our usual networks. They introduce novelty and challenge groupthink, something every CEO navigating complexity should pay attention to. The Leadership Lens When I work with CEOs, those in peer networks always value that outside in perspective, a fresh set of eyes. When I interviewed Tom Morgan for The Unlikely Executive Podcast he highlighted the power of talking to absolute strangers. His stranger was on the side of a soccer pitch. Showing that real breakthroughs can happen when you put down your guard and just share what your thoughts and ideas are. The 5 Voices framework reminds us that each person has a unique voice—and when we only surround ourselves with people who speak “like us,” we lose access to vital perspectives. When leaders only stay within their trusted circle, something important is lost. You may protect consistency and control (a strength of the Guardian), but you risk missing the unexpected insight that could change everything. Often, it’s the Creative or Connector in the room who first sees the value in an offhand comment or a half-formed idea. These seemingly small conversations—ones we often don’t prioritise—are where innovation is born.” The Call So here’s an invitation: be deliberate about bumping into brilliance. Attend a meet-up that’s outside your industry. Talk to a stranger, say hello as a starter! This method was used by Mel Robbins to great effect when she moved home and is outlined in her brilliant book Let Them. Most of all, create cultures where your team talks beyond their silos too. You might be surprised by where the next big idea comes from—and who it comes from. Curious what kind of conversations might unlock new thinking for you as a leader? Let’s talk. barbra@gleecoaching.com

Introduction Starting a business with friends is thrilling. There is an overarching sense of relief that you don't have to do it alone -you can do it with your bestie! yay! Fast forward 18 months, and the Yay! can turn into Nay! Misaligned expectations, unspoken assumptions, and personality clashes often threaten what was once a shared vision. How can co-directors stay aligned—and stay friends? The Research The UK’s ScaleUp Institute (2022) found that the biggest internal challenge to scale-up growth isn’t funding or sales—it’s leadership alignment. Misalignment at the top leads to strategic drift, team confusion, and burnout. The London Business School’s study on entrepreneurial team dynamics (Lechler & Ensley, 2021) highlights that psychological safety, clear communication, and complementary leadership styles are essential for co-founder success. The Voice of Alignment Most founder teams don’t fall apart because they disagree on what they want to build. It’s how they build it—how they make decisions, how they handle conflict, how they communicate under pressure. One founder might lead with relentless vision, what I call the Pioneer perspective, while another is carefully evaluating risk (taking a Guardian perspective). One might want harmony above all else (Nurturer), and another thrives on energy and visibility (Connector). The key is not to flatten those differences, but to name and honour them.” As a co-director of a brilliant social research agency Michael and I were super excited when we set out - we even got to take clients with us! Yay! However our personalities and life stage were so so different that tensions started to arise. - One of us wanted to renegotiate the agreed starting salary - one of us didn't - One of us was a laissez faire leader, one of us wasn't - One of us put our people first, one of us didn't - One of us blended work with social life, the other just wanted to go home and be with their family - One of us was single and footloose, one of us was married with responsibilities. None of the above were unresolvable but we were unable to resolve due to lack of appreciation of each other, and pressures from around us. I wish I had sought out the support of a coach, I would have loved it if we had both had coaching before it was too late. The Call If you’re building something with someone you respect and care about, take the time to build how you build. A business plan is vital—but so is a relationship plan. Talk to one another about your needs and desires, and share your observations on how you think the relationship, not just the business is going. Let’s ensure your founding team is aligned not just on the product, but on purpose, pace, and process. If you want to run through your thoughts get in touch with me, I would love to be able to help you, and your friend, be totally awesome! https://zcal.co/barbracarlisle/30min
