How do leaders influence culture without meaning to?

This is the uncomfortable part of leading at the top. Your culture is shaped less by what you say and more by what people see you do, especially the small things you don’t think anyone is watching. This post looks at the four signals that carry most of that message, and at why the one you think is clearest is often the one being misread.

How do leaders influence culture?

Through repeated, visible behaviour. People work out what really counts by watching what a senior leader reacts to, asks about, thanks people for and lets pass. They copy what they see, and they pass it on to their own teams.

That’s why “culture” can feel so hard to change by announcement. A statement is one signal. Your behaviour is hundreds of signals a week, and people trust the larger sample.

The phrase people often use for this is the shadow of the leader: the effect your everyday behaviour has on the people around you, well beyond what you intend. At Coach42 we look at it through four signals of our own:

• Mood: how you seem, and how that spreads.
• Attention: what you ask about, check and follow up on.
• What you praise: who and what gets thanked, and in front of whom.
• What you tolerate: what you see and don’t act on.

None of these is a policy. All of them are read as one.

Why do small signals from the top travel so far?

Because at this level people are watching closely, and they pass on what they see. A director who notices what you ask about in the board pack will start asking their own managers the same thing. Within weeks it has reached people who have never been in a room with you.

The stakes are real. In research for MIT Sloan Management Review, Donald Sull, Charles Sull and Ben Zweig found that a toxic corporate culture is “by far the strongest predictor of industry-adjusted attrition.” A chart in the article says a toxic culture is “10.4 times more likely to contribute to attrition than compensation.” Culture isn’t a soft extra. It’s one of the main reasons people leave.

And senior leaders have unusual reach over it. The CXO stage page puts it simply: your influence is at its widest just as honest feedback gets thinnest. So the signals travel further while the news about how they land travels back more slowly.

What does your mood signal?

That it’s safe, or not, to bring you bad news today. People read your mood before they read your words, and adjust what they say to match it.

We’ve written about how far moods spread in How far does emotional contagion at work spread?, so we won’t repeat the research here. The point for culture is narrower. Over time, people stop reacting to your mood on a given day and start reacting to the pattern. If your bad days are frequent or hard to predict, they learn to time their news, soften it or hold it back. That’s how a mood becomes a culture of waiting for the right moment.

What does your attention signal?

What really matters, whatever the plan says. The questions you ask and the numbers you check tell people which parts of their work are being watched, and so which parts are worth doing well.

If you say quality comes first but every review opens with the delivery date, people hear “dates first”. If you say you care about developing people but only ask about headcount, your leaders learn that development is something to mention, not something to report on. Nobody decided this. They simply noticed where your questions went.

Attention is the easiest signal to change, because you control your own agenda. Look at your last five leadership meetings and note the first question you asked in each. Those five questions are a fair summary of what your organisation thinks you care about.

What does your praise signal?

What success looks like, to everyone who is watching. Praise isn’t only a reward for the person who gets it. It’s a lesson for the people who don’t.

Gallup’s work on recognition makes exactly this point. It says recognition “sends messages to other employees about what success looks like,” and describes it as a chance “to reinforce the desired culture” of the organisation. Gallup also found that the most memorable recognition comes most often from a person’s manager, followed by “a high-level leader or CEO”. Your thanks carries weight.

That cuts both ways. If you publicly thank the person who stayed up all night to rescue a launch, people learn that rescues get noticed. If you rarely thank the person whose careful planning meant nothing needed rescuing, they learn that prevention is invisible. Over a year, you get more heroes and more fires.

A useful check: think of the last three people you praised in front of others. What did they actually do? Would you be happy if everyone copied it?

What does what you tolerate signal?

That it’s allowed. When a senior leader sees a problem and doesn’t act, people rarely read the silence as patience or tact. They read it as permission.

This is the idea behind the phrase “what you tolerate, you encourage”. It shows up in the data too. In the same MIT Sloan Management Review study, the authors note that companies that fail to recognise strong performers have higher attrition, and “the same is true for employers that tolerate underperformance.” The people who leave are often the ones who were doing the work you let someone else skip.

Tolerance is the hardest signal to see from your own seat, because it’s made of things you didn’t do. You let a missed deadline go because the person was having a hard time. You let a brilliant leader keep interrupting because their results are strong. Each choice has a reason. But the people watching don’t see the reason. They see the outcome: this is allowed here.

What does this look like in a real quarter?

Here’s a hypothetical example. A chief executive of a mid-sized firm has just launched a new set of values, including “we speak up early”. She believes in it and talks about it often. Here’s one quarter.

• Mood: in the month after a weak set of results she is visibly tense in leadership meetings. A finance lead who spotted a forecasting problem decides to wait until things calm down.
• Attention: every weekly review opens with the sales pipeline. Nobody is asked about risks until the last ten minutes, when time is short.
• Praise: at the quarterly all-hands she thanks a team that worked through a weekend to recover a late client project. The team that raised the same risk on a different project three weeks earlier, and avoided the problem, isn’t mentioned.
• Tolerance: a senior leader regularly dismisses concerns from junior colleagues in meetings. She notices, plans to raise it privately, and doesn’t get round to it.

She did nothing unkind. Her values are sincere. But in one quarter her organisation learned that bad news should wait, risks come last, recovery is rewarded and prevention isn’t, and speaking up to a senior person can be brushed aside without consequence. The values say “speak up early”. The signals say the opposite, and people believe the signals.

The fix isn’t a new values campaign. It’s four small moves: name her tension briefly and invite the bad news anyway, open each review with risks, thank the team that prevented a problem in the next all-hands, and have the private conversation with the senior leader this week.

Why are your signals so often misread?

Because people read your signals through their own position, not your intention. You know why you did something. They only see what you did, and they fill in the reason themselves, usually cautiously.

A short reply that meant “I’m between meetings” can read as “I’m unhappy with this.” A decision not to step in, meant as trust, can read as indifference. Praise for one team, meant as encouragement, can read as a ranking. The more senior you are, the more people have riding on getting your meaning right, so the more carefully, and anxiously, they interpret it.

That’s why most leaders have one signal that comes across clearly and one that is regularly misread. The clear one is usually where your behaviour matches your words. The misread one is usually where you’re relying on people to know what you meant. It’s also why asking directly matters. The post on how to find out what your team really thinks of you covers how to make that question safe to answer honestly.

How do you change the signal you send?

Change one visible behaviour and keep it up long enough to be noticed. Signals are learned from patterns, so a single gesture rarely shifts them. Three or four weeks of the same small change usually does more than one big speech.

A few principles help:

• Say what you’re changing. “I’m going to start every review with risks” tells people to look for it, so the new signal lands faster.
• Pick the signal, not the slogan. If you want people to speak up, change what happens when they do, starting with your first reaction.
• Act on one thing you’ve been tolerating. Nothing resets a signal faster than people seeing that something which used to pass now doesn’t.
• Check how it’s landing. Ask two or three people what they’ve noticed. If nobody has, it isn’t a signal yet.

How do you find out what your shadow looks like?

Start by rating yourself honestly on each signal, then find out how others read them. Most leaders have a clearest signal and a most misread one, and knowing which is which tells you where to start.

Shadow 360 is a free test built for this. It takes about 5 minutes, needs no sign-up, and your answers stay in your browser. You answer 14 questions about how your signals are read across the four areas in this post: mood, attention, what you praise and what you tolerate. You get a shadow profile that names your clearest signal and the one most likely to be misread, each with one move to try.

For now, you rate yourself. A team version, where your leadership team answers anonymously, is coming, and that will be the more honest view, because the gap between how you see your signals and how they’re read is the useful part. Either way, the profile isn’t a diagnosis. It’s a prompt to look at the habits your organisation is copying. You can read more about the test on the Shadow 360 page.

If you want a wider read on how you lead, including how quickly you tell people the hard thing, try The 42 Test. And if you suspect your signals are coming back to you filtered, The Echo Chamber looks at how honest the information reaching you really is. You’ll find the other tools for this stage on the CXOs page.

Your culture isn’t only the values on the wall. It’s what you were in a hurry about, what you asked first, who you thanked and what you let go, repeated every week. Pick the signal you think is clearest, and check whether it really is.
