Culture, AI, and the Forces You Don’t Control
I’ve been giving considerable thought to the “dance” we are currently in with AI. This, I feel compelled to say, was not written using AI.
Let me posit a hypothesis.
Strategy sits atop the pyramid when it comes to effective corporate operations. While definitions vary, most strategic thinking follows a consistent pattern: strategy originates at the top of the organisation and becomes the rallying point for focus, resources, and effort. From strategy flows intent, priorities, planning, and ultimately execution.
Then Peter Drucker offers his well-known observation: “Culture eats strategy for breakfast.” We all nod in agreement.
What follows is where things become interesting and revealing.
If culture is that important, the natural instinct is to try to architect it from the top down. It’s a logical idea, but it’s flawed. Research consistently shows that formal, top-down efforts account for only about 30% of an organisation’s culture. The remaining 70% forms and spreads through informal networks, peer interactions, local norms, and day-to-day behaviours.

Culture is a local construct. Why is that?
Unlike strategy, which is inherently top-down, culture is largely bottom-up. The reason is simple:
Character → Behaviour → Culture
Individual character drives behaviour. The aggregate of behaviours shapes culture. Conceptually, this is straightforward. Operationally, it is extremely difficult to control.
At best, organisations can do two things:
Build systems that allow them to observe and measure how culture is forming and spreading
Influence the limited set of levers that sit within that controllable 30%
AI adoption is accelerating at a pace unlike any prior technological shift. In doing so, it is shaping a new behavioural pattern, a heuristic, with several key characteristics:
AI systems are not neutral or unbiased
Humans are predisposed to trust AI outputs
Increased usage raises the likelihood of “cognitive surrender” (the gradual delegation of critical thinking and decision-making to AI)
As employees spend more time interacting with AI, the system begins to influence behaviour. As behaviour shifts, so too does culture.
Which leads to the implication:
AI is no longer just a tool for productivity, it is becoming a culture carrier.
For the first time, a non-human actor is influencing behaviour at scale, quietly, continuously, and without formal oversight.
And unlike previous cultural forces:
It does not sit within your organisational chart
It is not bound by your values
It cannot be coached, managed, or held accountable
Yet it is shaping how your people:
Think
Decide
Communicate
Solve problems
In effect, organisations are allowing an external intelligence layer to participate in culture formation without any meaningful visibility into how that influence is spreading.
The question becomes:
“Do we have the ability to observe and understand how AI is reshaping behaviour inside our organisation?”
If you cannot see it, you cannot manage, guide or align it to your strategy.
Hypothesis: As that influence grows, it becomes a core leadership responsibility, not a peripheral concern.
