You can't publish a culture.

The diagnosis is usually wrong.

What I want you to consider this week is that you have not built a culture; you have published one. And every person on your team has been quietly ignoring what is on the wall, in favour of what they can see happening in the room.

When Satya Nadella took over Microsoft in 2014, the culture was famously cutthroat. Stack ranking had pitted teams against each other for years, engineers hoarded information, and the senior leadership meeting was, by his own account, where careful argument went to die. He did not issue a values statement. He changed what people saw. At his first senior offsite he asked every executive to share a personal passion before any business was discussed; he talked openly about his son, born with severe cerebral palsy, in rooms where leaders are expected to project competence; he stopped rewarding the loudest voice and started visibly listening to engineers two and three layers down.

His private rule, repeated in interviews afterwards, was that the senior team had to embody the change before anyone else would be asked to. Within three years engagement scores and Glassdoor reviews showed a measurable shift, and Microsoft's market capitalisation grew from roughly three hundred billion dollars to over two trillion in his first eight years. The values had been on the wall the whole time. What changed was the visible pattern in the room. Behavioural science has a name for this gap: injunctive norms are what people say they approve of; descriptive norms are what they actually do. When the two diverge, people copy what they watch, not what they are told.

Here is the uncomfortable part. Cialdini's litter studies, Goldstein's hotel towel research, Schultz's energy experiments, Tankard and Paluck across organisations, Bicchieri systematising it; three decades of evidence converge on one finding. People copy what they see others doing far more reliably than they enact what they say they value, and the closer the model, the harder the pull. So your senior team is the highest-leverage cultural variable in the room, because they are the most watched and the most copied. You don't legislate a culture into existence. You grow it, in front of people who are paying attention.

Your team are learning company values from what they see, not the pretty poster.

The one thing

Audit what the room actually watched

Pick one of your stated values. In the next forty-eight hours, write down three specific behaviours you have visibly modelled that demonstrate it; not what you have said, what your team has watched you do. If you can't fill the list, you have your answer. Then, in your next meeting, do one thing that demonstrates the value, and amplify someone else who did the same.

Your team is not waiting for the next values document. They are watching what the senior team is visibly doing in the room. The culture you have is not the one on the wall; it is the one you are demonstrating today, whether you meant to or not.
