The Problem with Absolute Safety
Picture the Athenian agora. The marketplace of ideas. A place where philosophers, merchants, and statesmen gathered to debate, challenge, and refine their thinking. Now imagine a version of the agora where every idea was met with uncritical nods. Where Socrates, instead of provoking and questioning, simply affirmed whatever was said. That isn’t an agora - it’s an echo chamber.
This, in essence, is the problem with psychological safety when taken to its extreme. It’s an invaluable tool - one that fosters trust, open dialogue, and collaboration - but when dialled up to ten, it becomes an impediment, rather than an asset. The assumption that more safety always equals more performance might make us feel warm and fuzzy, but it’s a flawed notion.
“Innovation is born from the collision of ideas, not their agreement”
The best teams don’t operate in a state of perfect ease. They don’t exist in an environment where everyone agrees all the time, where risk-taking is entirely devoid of consequences, or where challenge is mistaken for hostility.
They thrive on a delicate balance - a constructive discomfort that allows for both trust and tension.
Psychological Safety: A Quick primer
The term psychological safety was first coined by Amy Edmondson, a Harvard professor who studied teams in high-stakes environments. Her research showed that the most effective teams weren’t necessarily the ones with the smartest individuals but those where members felt safe to speak up, admit mistakes, and challenge each other without fear of punishment or humiliation.
“Without psychological safety, fear becomes the dominant force, preventing innovation, engagement, and risk-taking”
Then came Google’s Project Aristotle. After studying hundreds of teams, Google researchers declared psychological safety the key determinant of high performance. The findings spread like wildfire. Leadership books, HR workshops, and executive coaches championed it as a silver bullet for innovation and performance.
And they weren’t wrong - at least, not entirely. Psychological safety is foundational to great teams. Without it, people stay silent when they should speak up. They withhold ideas, avoid accountability, and fear taking necessary risks. The problem isn’t psychological safety itself. The problem is the uncritical assumption that more is always better.
The 10/10 Fallacy
Seeing the woods for the trees…
Think of psychological safety as an airbag in a car. If it doesn’t deploy when needed, the results can be catastrophic. But if it deploys all the time - if every minor bump triggers it - it becomes a liability. An overinflated airbag can be just as dangerous as one that fails.
Teams that function in a state of absolute psychological safety can fall into one of three traps:
The Accountability Vacuum – When safety is mistaken for comfort, people become reluctant to challenge underperformance. Poor decisions go unchecked. Constructive friction fades. The result? Mediocrity.
The Echo Chamber Effect – A team so focused on making everyone feel safe that dissenting views are softened, sidestepped, or self-censored. The best ideas rarely emerge from polite agreement; they come from the productive clash of differing perspectives.
The Fear of Friction – True psychological safety isn’t about removing conflict - it’s about making conflict safe. Complete safety can lead to an aversion to difficult conversations, depriving teams of the accountability that drives real breakthroughs.
In The Five Dysfunctions of a Team, Patrick Lencioni points out that a fear of conflict is one of the greatest barriers to high performance. If people prioritise harmony over honesty, progress stalls. If critique is perceived as an attack, teams lose their ability to refine and sharpen ideas.
The Science of Constructive Discomfort
The most successful teams don’t operate at the extremes. They exist in a sweet spot where psychological safety and accountability coexist. Edmondson herself clarifies this point: high psychological safety without accountability leads to complacency; high accountability without psychological safety leads to anxiety. The ideal team culture sits in the intersection—where trust enables candour, and candour drives excellence.
This idea isn’t just theoretical. A 2017 study published in the Journal of Applied Psychology found that teams with moderate levels of task conflict (as opposed to none at all) consistently outperformed those in environments that were either too hostile or too safe. The reason? Task conflict fosters better decision-making, critical thinking, and innovation; provided it exists in a psychologically safe container.
In other words, the highest-performing teams argue. They debate. They push each other. Not in a way that creates fear, but in a way that demands rigour.
They are safe enough to be vulnerable, but not so safe that they lose their edge.
the Art of Productive Tension
Teams need healthy tension to thrive
Plato would have understood this balance intuitively. His Socratic dialogues were built on challenge - on the idea that knowledge isn’t found in easy consensus but in relentless questioning. The goal was never comfort. It was clarity. The same principle applies to great teams.
A boardroom (or any outcomes-driven arena) should function like a well-run symposium.
Ideas must be tested, refined, and debated. Not all ideas should be treated equally. Not all contributions should be affirmed uncritically. Some should be met with scepticism. Some should be torn apart and rebuilt.
“The best ideas emerge when there is a balance between challenge and support”
This doesn’t mean reverting to a culture of fear. It means recognising that safety and challenge must exist in tension. It means aiming for 8/10 psychological safety - not a perfect 10. There must be accountability, there must be consequences, but also the knowledge that no matter what, you will be treated with dignity and respect.
It means embracing the Socratic ideal that real progress comes from hard conversations, not soft consensus.
Steps to Create a High-Performance Environment
Encourage Healthy Disagreement – Create an environment where constructive dissent is expected and valued. Reward those who challenge assumptions, rather than those who simply agree.
Balance Safety with Accountability – Make it clear that psychological safety does not mean avoiding responsibility. Ensure that high standards of performance are maintained alongside open dialogue.
Develop Resilience to Feedback – Train teams to handle criticism without taking it personally. Reinforce that challenging ideas is a way to strengthen them, not a personal attack.
Introduce Structured Debate – Implement mechanisms like the devil’s advocate role or formal challenge sessions where dissenting views are actively encouraged and explored.
Model the Right Behaviour – Leaders should demonstrate vulnerability by admitting mistakes while also showing a willingness to engage in difficult conversations.
“Truth springs from argument amongst friends”
Closing Thoughts
The best teams aren’t the ones with the least conflict. They are the ones that know how to engage in conflict well. Psychological safety is essential, but it isn’t the final destination - it’s the starting point.
A team that prioritises comfort over candour, affirmation over accountability, or harmony over hard truths isn’t a high-performing team. It’s just a nice team…
…and nice teams don’t change the world.
