Leaders are nearly ten times more likely to be criticized by their teams for under-communicating than for over-communicating. That number comes from Stanford research by Francis Flynn and Chelsea Lide, who analyzed 2,717 written comments from leadership assessments and found that fewer than a quarter of employees rated their manager as well-calibrated on how much they communicated. The rest mostly wanted more. Not more meetings. More signal about what actually matters and why.

If you manage people, sit with that ratio for a second. The thing you are most worried about, that you talk too much and annoy your team, almost never happens. The thing you barely worry about, that you said something important once and assumed it landed, is the failure mode your people notice ten times as often. Most managers are calibrated exactly backward.

Sent is not the same as received

Here is the trap. You decided the new priority in a leadership meeting on Tuesday. You mentioned it at standup Wednesday. In your head, the message is now delivered. Filed. Done. You have moved on to the next problem, and you assume the team has the destination locked in.

Your team experienced something completely different. Half of them were half-listening at standup because they were finishing a thought about their own work. Two people were out that day. One heard it but assumed it was a passing idea, not a real change, because you say a lot of things at standup. By Friday, the priority you consider settled exists clearly in exactly one head. Yours.

Flynn’s explanation for why this happens is worth understanding, because it is not about laziness. Managers under-communicate because they suffer from what the researchers call miscalibration. You already know the context, the reasoning, the backstory, so repeating it feels redundant and slightly insulting to smart adults. But your team does not live inside your head. When you stay quiet to respect their intelligence, they do not read it as respect. Flynn found that employees interpret a manager’s silence as apathy, not autonomy. The most damaging finding in the study is that under-communicating leaders scored dramatically lower on perceived empathy. Say too little and your people do not conclude that you trust them. They conclude that you do not care.

Repeating yourself is a strategy, not a character flaw

The instinct to say something once and move on treats repetition as a weakness, something insecure managers do. The evidence points the other way.

Paul Leonardi and Tsedal Neeley, then at Northwestern and Harvard, shadowed 13 project managers across six companies for 256 hours in computing, telecommunications, and healthcare. They were watching how the work actually moved. What they noticed was that some managers deliberately sent the same message more than once, through different channels. They would say a thing face to face, then follow it with an email, then mention it again in a text or a chat message. The researchers called this redundant communication, and their published finding in Organization Science was that the managers who did it moved their projects forward faster and more smoothly than the ones who did not.

Neeley’s own reaction to the data is the part I keep coming back to. She said she was stunned, because she expected clarity to be the thing that mattered. It was not. Even perfectly clear messages needed to be repeated to reliably land. The redundancy was not compensating for a bad first message. It was doing work the first message could not do on its own.

The pattern got sharper when they split the managers by authority. Managers with no formal power over their teams used redundant communication 21% of the time, nearly double the 12% rate of managers who could just give orders. The people who could not pull rank were the most deliberate about repeating themselves, and they were often the ones who got teams to move. Repetition was how they manufactured urgency they could not command. If that is the tool the least powerful managers reach for and it works, the manager who refuses to repeat anything is not being efficient. They are skipping the step that makes influence stick.

What happens when you skip it

Years ago, running IT operations, I rolled out a change to how my team handled incoming support tickets. Clear rationale, one all-hands walkthrough, a written doc in the shared drive. I considered it communicated and turned my attention elsewhere. Three weeks later I discovered that roughly half the team was still working the old way. Not out of resistance. They had heard the walkthrough as a suggestion, filed the doc as reference material they would read if a problem came up, and defaulted back to muscle memory the moment the meeting ended.

My first reaction was irritation at them. That was wrong, and it took me an embarrassingly long time to see it. I had communicated the change exactly once, through one channel, on one day, and then measured my team against a standard I had barely transmitted. The failure was mine. When I reran it, I said the same thing in the team meeting, repeated it in each of my one-on-ones that week, wrote it up again in plainer language, and brought it up once more the following Monday. That time it stuck. Nothing about the message improved. The only thing that changed was that I said it four times instead of once.

The second channel does the work the first one missed

There is a reason different media matter, not just more repetition through the same pipe. Each channel reaches a different version of the person’s attention.

A hallway conversation carries tone and lets them ask a question in the moment, but it evaporates the instant they walk away. A written message survives, gets forwarded, and can be reread, but it lands flat and easy to skim past. Saying it in a group meeting signals that it is a shared expectation, not a private aside. When you deliver the same point across two or three of these, you are not being repetitive for its own sake. You are catching the person who tuned out the meeting but reads every email, and the person who ignores email but remembers exactly what you said to their face.

This is the logic behind what some communication coaches now call the 5×5 approach: say the most important things five times, in five different ways. The number is less the point than the principle. A message delivered through one channel on one day is a message betting everything on that channel reaching everyone in the right frame of mind. It rarely does.

Repeat the few things, not everything

The obvious risk is that a manager reads all this and starts repeating everything, which produces noise and buries the signal. That is not what the research supports and not what good communicators do. Over-communicating gets forgiven far more readily than under-communicating, but that is not a license to flood people. The discipline is selective.

Repeat the small number of things that actually steer decisions and behavior when you are not in the room:

• The current priority and why it beats the other things competing for attention
• The standard you expect, in concrete terms, especially right after you change it
• The reasoning behind a decision people have to carry out without you there to explain it
• The direction and intent that lets someone make a good call on their own

Notice what is not on that list. Routine status, one-off requests, and information people can look up do not need the redundancy treatment. Repeat those and you train your team to tune you out, which makes the repetition worthless when you actually need it. The signal only works because you reserve it. A useful test before you decide something is communicated: could a reasonable person on my team make the wrong call next week and honestly say they never got the message? If yes, you have not communicated it. You have mentioned it.

The uncomfortable reframe

The manager who says a thing once and expects it to stick is not being respectful of their team’s intelligence, though that is the story they tell themselves. They are outsourcing the hard part of communication, making sure the message actually landed, onto people who have their own work to hold in their heads and no view into what is important to you unless you tell them, repeatedly and in more than one form.

Communication is not an event you complete. It is a thing you maintain, like trust, and it decays the moment you stop. The best communicators I have worked with were not more eloquent than everyone else. They were more willing to say the important things again, on purpose, until they were sure the team could repeat those things back. That is not nagging. On the evidence, it is most of the job.
