Psychological safety isn't just for teams. Management teams need it too.
Google's most famous research found that safety, not talent, predicts high performance. Almost nobody applies that finding to the room full of managers running the company.
Google's Project Aristotle is one of the most cited pieces of workplace research of the last decade, and almost all of it gets applied in one direction: helping individual contributors feel safe on their teams. Fewer people ask the same question about the room one level up, the group of managers who run those teams. Do they feel safe telling each other when something's wrong?
The evidence says they should care just as much about the answer. Over two years, Google studied 180 teams and measured 250 different attributes, from personality traits to how often teammates socialized outside work, and found that team composition mattered far less than expected. What mattered most was whether people felt safe speaking up, taking risks, and being vulnerable with each other. Nothing about that finding is specific to individual contributor teams. It applies just as directly to a room of department heads or a company's leadership team.
What the research actually found
Psychological safety turned out to matter more than raw talent, seniority, tenure, or team size, essentially confirming that how a team works together beats who happens to be on it. The specific behavior driving that result was whether team members felt they could express concerns without being shut down, whether mistakes could be raised without embarrassment, and whether people felt they'd be taken seriously.
A management team is, structurally, just another team. It has the same dynamics: some members more senior, some newer, some with stronger relationships to leadership than others. Those same dynamics can just as easily suppress honesty among managers as they can among individual contributors, and arguably with higher stakes, since a management team's decisions ripple down to everyone they lead.
The teams that outperformed weren't the ones with the most talented people. They were the ones where people felt safe enough to say when something was actually wrong.
What low safety looks like among managers specifically
Nobody admits a team is struggling
A manager whose team is underperforming has an incentive to present things as fine in front of peers, especially if admitting otherwise feels like admitting personal failure rather than a shared, solvable problem.
Concerns about a colleague go unspoken
If one manager notices a peer struggling, or handling something poorly, raising it directly can feel like an accusation rather than help, so it often just doesn't get raised at all.
Notes get softened before they're shared
If a management team shares employee notes with each other, a manager who doesn't feel safe can quietly sanitize what they write, leaving out the parts that might reflect badly on their own leadership.
Why the fourth signal is the one shared notes depend on
Follow-up research found people move through a fairly consistent progression when joining a new team: first they want to feel included, then they want to feel safe learning and asking questions, then they want to feel safe contributing their own ideas, and only after all three does the final stage, feeling safe enough to challenge and push back, actually take hold. Skipping the earlier stages means the final one, the one that produces genuine honesty, never really develops.
That last stage is exactly what a shared note system depends on. If a manager doesn't feel safe enough to write "I don't think this promotion is ready yet" or "I made a mistake handling this conversation," in a place other managers can see it, the record itself becomes quietly unreliable, filled with polished summaries instead of honest ones. The system doesn't fail because the tool is wrong. It fails because the safety underneath it was never built.
What actually builds it
Leaders set the tone more than any policy does. When a leader is willing to admit their own mistakes and ask for feedback openly, it becomes noticeably easier for others to do the same. On a management team specifically, this means the most senior person in the room needs to be the first to write an honest, unflattering note about their own handling of a situation, not just encourage everyone else to.
It's worth being clear about what psychological safety isn't. It doesn't mean comfort or the absence of disagreement. Genuine safety actually makes room for more disagreement and challenge, not less, because people no longer fear punishment for raising it. A management team with high safety should look like more open disagreement about decisions, not less, and more honest notes about what isn't working, not a tidier, more polished record.
A simple test for where your management team stands
Look at how notes get written across your management team right now. Do they read as honest, including the uncomfortable parts, or do they read as uniformly positive summaries? A record where every note describes things going smoothly, even for employees everyone privately knows are struggling, is a strong sign that safety, not the note-taking habit itself, is the actual problem.
Try this at your next leadership meeting: Share one honest, slightly uncomfortable note about a mistake you made or a situation you handled imperfectly. Notice whether that opens the door for anyone else to do the same. That's the real measure of whether your management team has the safety Google's research says actually predicts performance.
