In 2025, there were 100 million knowledge workers in the U.S. alone, representing up to 42% of the workforce. Worldwide, that number is over 1 billion. The currency of knowledge workers—their contribution to their team and their workplace—is information. Ideas, thoughts, and the deliverables that come from these ideas. But sharing ideas, truly valuable ideas, can be risky.
People who don’t feel safe to take these risks have less to share, and their team suffers for it. That’s psychological safety in a nutshell: the feeling that you can safely share ideas, challenge the status quo, and admit mistakes without being unjustly punished.
Leaders play a key role in introducing, promoting, and protecting psychological safety at work. Not just by approving policies, but by living its tenets. That includes showing vulnerability.
Because, when it comes to leadership, vulnerability isn’t a sign of weakness. It’s actually a sign of strength. A leader who comes to the people they serve to admit mistakes, solicit feedback, and ask for help is a model for behaviors that create psychological safety throughout the organization.
Here’s how.
Key Takeaways:

- Platforms like 15Five Engage help operationalize and scale these efforts
What is psychological safety? Why does it matter?
What is psychological safety?
In her 1999 paper, Psychological Safety and Learning Behavior in Work Teams, Harvard economist and leadership expert Amy Edmondson coined the term “psychological safety.” She defines it as “a shared belief held by members of a team that the team is safe for interpersonal risk taking.” Risk-taking can be anything from admitting you made an error to asking for help or publicly disagreeing with a leader.
Workplaces where psychological safety is the norm are easily recognizable. How many people feel comfortable enough to raise their hand at an all-hands meeting? Do teams freely ask for help and collaborate, or are they locked in intense competition? Are mistakes turned into learning opportunities or severely punished?
Psychological safety isn’t about agreeing with everyone’s opinion or failing to recognize mistakes when they happen. It’s about decoupling fear and risk from mistakes, dissent, and requests for help.
The business impact of psychological safety at work
When your business runs on the quality of the ideas and information it produces, an environment where everyone feels free to share their ideas and correct mistakes leads to better results. Research from the Center for Creative Leadership shows that teams with high levels of psychological safety reported better performance and less interpersonal conflict.
But this holds through even in other fields where ideas might not be the currency but psychological safety is still vital, whether that’s manufacturing, logistics, or the trades. According to Accenture data, high psychological safety at work reduces stress by 74%.
Less stress, better performance, more innovation, and stronger collaboration. Psychological safety is the key to it all.
The connection between leadership behavior and safety
Leaders establish company culture and, through their actions, show the rest of the organization how to live it in day-to-day work. The same is true with psychological safety. While leaders might not be directly involved in, say, reacting to mistakes from individual contributors, they can still demonstrate how they should be handled.
How? Vulnerability.
The role of vulnerability in leadership
In psychology, vulnerability includes exposing yourself to potential emotional harm, facing opportunities for criticism, and taking similar risks. Here’s why it’s so vital in leadership.
Why vulnerability builds trust
The power that comes with leadership can make promoting psychological safety more complex. When a worker comes forward with a mistake, they’re taking a risk that a leader might not fully understand—or even be able to take themselves. They’re vulnerable because of their position, not necessarily by choice.
Because a leader’s position is inherently less vulnerable to the risks that come with admitting mistakes or asking for help, leaders need to demonstrate vulnerability by intentionally taking these risks and doing so publicly. When leaders give everyone more opportunities to share feedback and admit their mistakes, they create transparency and come across as more authentic. By creating situations where they publicly take these risks, they model the psychological safety they want to see.
Common misconceptions about vulnerability
The word “vulnerability” might conjure images like a dog rolling onto its back after a fight or a leader oversharing about their personal life with employees. But it’s not submitting yourself to attack or breaching boundaries between work and private life; it’s a deliberate choice to live your company culture transparently.
Vulnerability means going out of your way to take the risks you want employees to take and showing that it’s safe to do so.
The neuroscience of trust and safety
Have you ever had a conflict with a colleague that seemed to spiral far beyond the gravity of the original trigger? That’s because the amygdala, the brain’s alarm system, triggers the same fight-or-flight response whether you’re in physical danger or facing a social threat (e.g., harsh criticism, social rejection, or job insecurity). To counter that reaction, employees need evidence that admitting a mistake or taking a risk won’t result in these threats, which leaders can demonstrate with vulnerability.
How leaders can model vulnerability effectively
Demonstrating vulnerability at a leadership level lays the foundation for a culture of psychological safety. Here are the actual actions leaders can take to do this.
Admit mistakes openly
Admitting a mistake at work can have significant consequences, especially when employees don’t feel psychologically safe. At best, there’ll be some criticism involved (whether fair or harsh). At worst, they might lose their job.
When leaders publicly admit their mistakes, they demonstrate that they, too, can be held accountable. But, more importantly, they show that accountability doesn’t have to come with blame or judgment. Say they admit that a strategic decision of theirs led to lower revenue last quarter, for example. That shows they’re taking responsibility for the company’s poor performance (and righting the ship) without expecting they’ll be fired for it.
Ask for feedback regularly
In many organizations, feedback feels like a threat. Employees feel like it’s used to beat them down, while managers might not open themselves up to it at all. Here, leaders can demonstrate vulnerability by opening themselves up to feedback and doing so frequently. If they’re able to address feedback directly and show how it impacts future decisions or actions, they’ll demonstrate that feedback is a useful tool, not a weapon.
Share decision-making processes
By sharing the logic (and the research) behind their decisions, leaders increase organizational transparency and reduce ambiguity, giving employees a more solid foundation to take risks. It also makes them more human.
Encourage questions and dissent
For employees to feel safe sharing feedback and questioning assumptions, leaders need to give them the space to do so. That means going beyond just asking for feedback. It needs to be encouraged through gratitude, positive encouragement, and follow-through. You don’t necessarily have to act on all the feedback you get, but make it public when you do.
Demonstrate empathy and active listening
If a leader asks for feedback but clearly isn’t listening when it’s given, employees won’t share it. Demonstrating empathy validates the risks employees take when sharing feedback, while active listening shows it isn’t wasted.
Creating psychological safety in the workplace through systems and training
Leaders can promote psychological safety by demonstrating vulnerability, opening their decision-making up to feedback, and sharing their mistakes publicly. But while this is foundational work, it’s not all you need to do.
Systems and training reinforce the example your leaders set. Leaders, managers, and individual collaborators all encounter opportunities to reinforce psychological safety; without the right systems and training, they might not know how to do so—let alone even recognize these opportunities.
The first step? Including psychological safety in workplace training. Whether it’s in onboarding or regular training sessions, reinforcing the value of psychological safety and how it’s lived can give employees and leaders clear reference points as they work.
Performance management is another area where you can integrate psychological safety. Performance reviews and similar evaluations allow managers to share feedback in a way that promotes safety, showing employees that mistakes are accounted for but not punished.
Process is how you build psychological safety systematically. Standardizing expectations and behaviors across departments creates a consistent employee experience that not only supports psychological safety but also turns everyone into champions who can recognize safe behaviors and promote them.
Using predictive HR analytics to measure and improve psychological safety
Most organizations use annual surveys and reactive initiatives to approach psychological safety. They’re either getting their data too late for it to be of much use or are always a step behind, trying to guess at what they need to do.
Predictive analytics can change that.
Why predictive HR analytics matters
Predictive analytics allow leaders to turn data into signals that predict declines in psychological safety before they happen. For example, if your employee engagement surveys include questions about psychological safety, tracking responses to these questions over time can show the success of your efforts to build that safety or the negative impacts of challenges your organization sees.
Key metrics for employee psychological safety
Measuring employee psychological safety is typically done with engagement surveys, pulse surveys, and 1-on-1 meetings. Frameworks like Edmondson’s Psychological Safety Index (from the same paper that the term originates from) can standardize the metrics used to do this. Edmondson’s framework, for example, uses these seven points:
- Do employees feel like mistakes are held against them?
- Can team members bring up problems and hard issues?
- Do people on a team reject others for being different?
- Is it safe to take risks on a specific team?
- Is it difficult to ask members of a specific team for help?
- Would team members act deliberately to undermine someone’s efforts?
- Unique skills and talents are valued and utilized when working with a specific team.

Best practices for sustaining psychological safety at work
As you build processes to promote and sustain psychological safety in your workplace, consider the following best practices.
Make safety measurable and visible
Dashboards and reporting tools (e.g., employee engagement surveys, pulse surveys) give leaders a way to measure psychological safety and tie it to initiatives, decisions, and strategy. With these tools, you can see patterns and trends that make psychological safety less of a guessing game.
Reinforce behaviors through recognition
Employees have a role to play in building and maintaining psychological safety: taking risks and owning up to mistakes. But that means leaders need to identify these behaviors and promote them when they occur. Public kudos and mentions at all-hands are important for doing this, as is private recognition in 1-on-1s.
Continuously invest in psychological safety training
Psychological safety training shouldn’t be a single, static session. As your organization grows and your business strategy changes, you’ll move through psychological safety stages, and your priorities will change. Your training should evolve to reflect that as well.
Integrate safety into organizational strategy
Psychological safety should be just as much of a priority as your other business objectives. By considering how you can grow this sense of safety and make it a part of other endeavors, you’ll unlock more performance and innovation throughout your workforce.
The 4 stages of psychological safety in the workplace
Timothy R. Clark, founder and CEO of LeaderFactor, created a framework for psychological safety in his book, The 4 Stages of Psychological Safety, which allows leaders to map their pursuit of psychological safety as an organizational goal with the natural progression of people’s psychological needs in social settings.
Stage 1: Inclusion safety
At its most basic level, psychological safety requires that employees feel connected to their peers and feel like they belong in their workplace. This includes feeling appreciated in their work and comfortable at the office.
Stage 2: Learner safety
People have an essential need to learn and grow, and that requires the ability to make mistakes without fearing the repercussions. At this stage, leaders need to encourage employees to stretch beyond their comfort zone, striking a balance between keeping them accountable for their mistakes and turning mistakes into learning opportunities.
Stage 3: Contributor safety
When people feel like they can participate as full-fledged team members, they can meet their basic need to contribute to something greater than themselves and make a difference. Leaders can encourage this stage of psychological safety by encouraging employees to think beyond the strict boundaries of their role (and rewarding them when they do).
Stage 4: Challenger safety
Employees want to feel like they can improve their workplace in one way or another. That means being able to challenge the status quo, disagree with leadership decisions, and express their opinions candidly. Leaders need to give employees opportunities to do this, do it safely, and see how it contributes to the workplace.
Bring psychological safety to your organization
Psychological safety cannot exist in an organization without leaders serving as examples of the behaviors they want to see or systems that reinforce the importance of that safety. Leaders can use vulnerability not only to show psychological safety in action, but as a core competency to become stronger leaders. Predictive analytics, dedicated training, and feedback loops can promote and sustain psychological safety, while data-driven insights can inform your strategy as your organization grows.
