Why the Best Teams Speak Up More.

You catch the mistake before anyone else does. A wrong number on a chart, a step skipped in a handoff, a detail that got missed because the day moved too fast to double-check. For a second, you just stand there.

Do you say something? Or fix it quietly, move on, and hope it doesn't come up again?

Most of us have been in that exact moment. And the choice we make in it says less about who we are than about the room we're standing in.

There's a well-known study behind that moment that captures this well. Researcher Amy Edmondson was studying teams in hospitals, looking at the relationship between teamwork and reported errors. The assumption seemed straightforward: the better the team, the fewer errors you'd expect to see. Instead, she found the reverse. The teams with stronger teamwork were reporting more errors, not fewer.

At first that reads like bad news. But there's another way to look at it. The strongest teams weren't necessarily making more mistakes than everyone else. They were just the ones willing to say so out loud. Everywhere else, the mistakes were likely still happening but staying quiet, fixed on the sly, left unreported, or turning up later, bigger, at a worse time. The difference wasn't necessarily in what went wrong. It was in what people felt able to say about it.

That observation became part of a much larger body of research that has led to what's now called psychological safety: the shared belief that you can speak up, ask a question, admit a mistake, or raise a concern without being punished or humiliated for doing so. It's not about making work comfortable all the time. It's about making it possible for people to be honest when honesty matters because when people feel safe enough to speak, things surface earlier.

The question gets asked before the misunderstanding becomes a problem. The concern gets raised while there's still time to do something about it. The mistake gets acknowledged while it's still small enough to learn from. And that matters far beyond mistakes.

Psychological safety also shapes whether someone says, "I don't understand."

Whether they ask, "Why are we doing it this way?"

Whether they offer a different idea.

Whether they disagree with the person in the room who has more authority.

Whether they tell you that something isn't working.

Whether they say, "I think there's a better way."

Or whether they simply stay quiet.

Feeling safe to speak is important, but it isn't the whole story. People also need to feel that their voice matters and that speaking up leads somewhere.

That's where autonomy and agency enter the conversation.

You don't need control over everything at work. None of us has that. But there is something different about having some influence over how you approach your work, how decisions affecting you are made, or whether your perspective can shape what happens next.

There's a difference between being invited to give your opinion and believing that your opinion might matter. And that distinction matters.

You can create a workplace where people are encouraged to speak up, but if nothing ever changes because they do, they'll eventually stop trying. Likewise, someone may have considerable freedom in their work but still hesitate to use their voice if they don't feel safe challenging an idea, admitting uncertainty, or pointing out a problem.

Having a voice doesn't help much if it isn't safe to use it. And feeling safe doesn't help much if you never have any real influence over what happens next.

Picture two people on the same team, both equally comfortable raising a scheduling problem with no concern anyone's going to snap at either of them for it. One raises it, and the schedule shifts the following week. The other raises it, watches nothing change, mentions it again a month later, and again nothing moves. By the third time, she stops bringing it up. Not because she stopped caring. Because she learned it doesn't do anything.

You can hear the split as three different questions, all being asked quietly at once:

Psychological safety asks: Can I speak?

Agency asks: Does my voice matter?

And team effectiveness asks: What happens because I spoke?

We often talk about psychological safety as something a leader can simply announce: "My door is always open, I want everyone to speak up." But people don't learn whether it's safe to speak from what they're told. They learn it from what happens the one time they actually try it. Met with curiosity, respect, and a genuine willingness to listen, they learn their voice is welcome. Met with silence, defensiveness, or nothing changing, they learn something else and they adjust, quietly, without telling anyone. Psychological safety isn't the same as trust, either, although the two are closely connected. That's a conversation for another time.

None of this shows up neatly on a performance review. Nobody puts "felt safe enough to speak up today" in a report. It shows up as the question that doesn't get asked in the meeting. The concern raised in the hallway afterward instead of in the room. The idea someone keeps to themselves because "it probably won't make a difference anyway." The mistake someone fixes quietly because raising it feels riskier than carrying it. Most of the time you won't notice psychological safety is missing. You'll just notice that people become a little more careful, a little quieter, a little less willing to challenge, question, suggest, or admit.

So, what kind of room are you creating?

The best teams aren't the ones without problems. They're the ones where problems can be surfaced early. They're not teams where everyone agrees. They're teams where disagreement can happen without becoming personal. They're not teams where people never make mistakes. They're teams where people can say "I got this wrong" and still feel like a valued member of the team. And they're not necessarily teams where everyone has control. They're teams where people have enough voice and influence to feel that their contribution matters.

So, the next time you're in a room at work, consider two questions:

If someone caught a mistake right now, would they say something?

And perhaps even more importantly: if they did, what would happen next?

Those two answers can tell you a lot about the wellbeing of a team.

 This is the kind of thing we spend a lot of our time on at Mingle & Marvel — not just how people are doing, but what makes it safe, and worthwhile, for them to say so. If that's a conversation worth having on your team, we'd love to help start it.
