The silence that should worry you most is the one after a mistake
Part 3 of a 4-part series: Activate psychological safety.
There is a moment that tells you more about a team's psychological safety than almost any survey or culture audit ever will.
It happens after something goes wrong.
Not a catastrophic failure. Those tend to surface loudly, with urgency and accountability attached. The moments that reveal the most are the smaller ones. A process that broke down quietly. A client interaction that went poorly. A decision that, in hindsight, was made on incomplete information that several people in the room actually had but did not share.
What happens next, in the hours and days that follow, is one of the most accurate readings of psychological safety a team can produce. In most organisations, what happens next is silence. Not the silence of people who have nothing to say. The silence of people who have decided it is not worth saying it.
Why error culture is the real test
In the first two articles in this series, we explored what psychological safety is and why it is a leadership behaviour rather than a culture initiative. Both of those things are true. But they can remain abstract until you locate them in a specific, observable moment.
Error culture is that moment made visible.
Amy Edmondson, whose research on psychological safety has shaped organisational thinking, surface mistakes faster, learn from them and prevent the same mistakes from compounding. The mechanism is simple. When people believe they will not be punished or humiliated for speaking up about a problem, they speak up. When they do not believe that, they stay quiet and the problem festers.
The 2026 COE Psychological Safety Study, drawing on clinical insights from workplace wellbeing professionals across 47 countries, confirms that this pattern is both widespread and worsening. In 2025, organisational culture placed greater emphasis on authenticity, trust, fairness and psychological safety, but the gap between what organisations say and what employees actually experience remained significant. The rhetoric of psychological safety has outpaced the practice of it.
The cost of getting this wrong
It is worth being precise about what is actually lost when error culture is poor.
The most obvious cost is repeated mistakes. When a team cannot speak openly about what went wrong, the conditions that produced the error remain unchanged. The same thing happens again - and the pattern holds.
The less obvious cost is the loss of near-miss information. In high-stakes environments such as healthcare, aviation, financial services and construction, the concept of a near miss is well understood. Something almost went wrong. If we can capture and learn from that, we prevent the thing that almost happened from actually happening. But near-miss information only reaches the people who can act on it if someone is willing to share it. In teams where error culture is poor, people do not share near misses. They stay quiet, move on and hope the same thing does not happen again.
The least visible cost is the erosion of innovation. Research consistently shows that a culture of openness enhances safety, innovation and ethical standards across all industries. When people are afraid to be wrong, they stop proposing things that might be wrong. They default to what is safe, familiar and unlikely to attract criticism. The result is organisations that describe themselves as innovative but whose cultures actively suppress the conditions innovation requires.
What leaders do without realising
The most common mistake leaders make around error culture is not deliberate. It is a pattern of subtle responses that accumulates into a clear message about what is and is not safe.
The response that takes three seconds too long when someone raises a problem. The meeting that moves briskly past the moment someone shares a difficulty. The leader who listens carefully to the description of what went wrong and then, shifts the conversation toward who was responsible rather than what can be learned.
None of these responses is necessarily harsh. Some are well-intentioned. But they produce the same effect as a harsher response would. People conclude that the cost of transparency is higher than the benefit, and they adjust their behaviour accordingly.
Leaders who build strong error culture are not necessarily the most charismatic or the most emotionally expressive. They are the ones who respond to bad news without shooting the messenger. The ones who ask questions they do not already know the answer to. The ones who change their minds visibly and acknowledge when someone else had the better idea. The ones who treat a mistake as information rather than a failing.
These are behavioural choices. They can be learned, practised and embedded. Which is both the challenge and the opportunity.
What good error culture looks like in practice
There are a handful of specific leadership behaviours that build error culture deliberately.
The first is narrating your own mistakes. When a leader says, openly, that they got something wrong, what they thought, what happened instead and what they will do differently, they do two things simultaneously. They model the behaviour they want from their team, and they demonstrate that the consequence of transparency is not punishment but learning. This is one of the most powerful things a leader can do.
The second is separating the debrief from the consequence. When something goes wrong, the instinct is often to address both the problem and the accountability in the same conversation. Sometimes that is necessary. But when they are conflated, when the conversation about what happened is also the conversation about what the consequences are, people learn to protect themselves in that conversation rather than contribute honestly to it. Where it is possible, separating the learning conversation from the accountability conversation produces better information and better outcomes.
The third is asking questions before drawing conclusions. The most psychologically safe response to a mistake is genuine curiosity. What happened? What were you working with? What would have needed to be different for a different outcome? These questions signal that the goal is understanding rather than judgment. They also produce far more useful information than a response that begins with an assessment.
Where this series is heading
The next and final article in the Activate series will bring this conversation to contemporary issues. The relationship between psychological safety and AI adoption. Because the conditions that determine whether a team can speak openly about mistakes are the same conditions that determine whether AI adoption will work or fail.
Both silences come from the same place. The team member who says nothing after a rollout announcement is often making the same calculation as the team member who says nothing after a mistake. They are reading the room, weighing the risk and concluding that the cost of speaking up is higher than the benefit of doing so. Changing that calculation is a leadership task, not a communications one.
Psychological safety does not build itself. It is the result of deliberate leadership choices made consistently over time, in the moments after a mistake, in the conversations that could easily be avoided, in the culture a team builds one interaction at a time.
