5 Reasons Culture Change Stalls When Leaders Overlook the Past

I don’t know about you, but when I read books and articles on culture change, they often leave me with a nagging feeling: Is that all?

Sure, the insights and advice usually make sense. Often, they’re even actionable. But it’s as if something’s off… Or incomplete. Like the most important truths have been left unsaid.

I say this not as an outsider or a theorist, but as someone who’s been in the thick of it — sitting at the boardroom table, navigating the turbulence of scale-ups, and leading change through buyouts and mergers.

And if there’s one thing I can say with confidence, it’s this…

Culture change resists being treated like a project. It’s a living system with memory. And it follows its own systemic logic. So it doesn’t bend neatly to plans, timelines, or slide decks.

Trust me, I’m not here to moralize. I’ve had mud on my boots, too. Having plans and rolling out culture programs. Falling flat on my face when I thought I had it all figured out. Getting humbled on the way.

But in time, those painful moments turned into gold. And they started serving the transformations I was part of, disarming and rewiring whole systems.

What I’m about to share here isn’t a magic formula or a glossy five-step process. It’s a series of hard-won lessons — uncomfortable truths that often get overlooked, rushed off, or avoided. Because they challenge our need for control, predictability, and polished image.

That’s why you rarely see them in books, articles, or strategy decks. But they quietly shape the undercurrent of how things really play out.

So here’s to the first in a series of reflections on my lessons learned of culture change.

1. Culture Has a Memory

In my early “prove-your-drive-and-value-fast” years, I believed culture could be designed. You create a vision. Share it during a high-vibe company retreat. Run values workshops and leadership programs to align behaviors with the new direction.

What could possibly go wrong? Well…

It’s not that these things are wrong. But merely relying on the momentum of fresh starts is like trying to swim forward while something invisible clings to your ankle beneath the surface. And no matter how strong your stroke, you’ll be pulled back by what you refuse to see.

Whenever we choose a new direction, there’s a reason for it. And if you’re leading culture change right now, you probably know this: it’s not happening in a vacuum.

It’s happening because the past ways of working can’t carry you to the future. Maybe they’ve become dysfunctional. Maybe they’re outdated. Or you’ve simply outgrown them.

2. Legacy Patterns Contradict the New Vision

Think of an organization shaped by years of top-down decisions. Now, the new leadership team wants to empower people, encouraging them to take initiative, take responsibility, and own their impact. What’s not to love about it?

The vision is compelling. But the fear-based habits of the past are still tied to everybody’s ankles. So despite the promise of more inspiring tomorrows, swimming in the new direction feels exhausting.

Because that legacy is encoded in people’s nervous systems. In their beliefs. And their habits. It’s encoded in the cultural DNA and in policies built on the old logic.

So you might preach about empowerment, but still require C-level approval for every new hire. You might promote initiative, yet spotlight those who follow old scripts and challenge those who leap but wobble.

I’ve been part of this too. But the lesson learned wasn’t just about spotting those contradictions. It’s about being willing to name them. To work with them. To publicly acknowledge them. Because that’s the medicine.

3. People Feel the Friction Before Leaders Admit It

If you don’t surface those contradictions, you’ll keep serving them. And your new culture narrative becomes just a shinier cover for an old system. Which makes things worse. Because now people feel the dissonance. And it drags them into the loop of spending their energy managing that tension instead of doing the work that matters.

When leaders don’t acknowledge the gap between old and new, trust erodes. Not because people resist change, but because they’re navigating mixed signals.

4. Leaders Try to “Fix Forward” Instead of Working With What’s Here

Let me be clear: contradictions aren’t the problem. Hiding them is.

Here’s the truth: The battle between old and new isn’t a failure. It’s a stage of transformation. And if there’s anything to be suspicious of in culture change, it’s neatness and harmony.

Because in real transformation, things don’t click right away. There’s friction that needs to be allowed to surface. The contradiction needs to be normalized. And the awkward overlap needs to be welcomed. And that requires honesty and space for the messy middle.

One example that comes to mind is a company I worked for some time ago. We were about to release a bonus policy that still centered individual performance — a legacy of the past — right when all our company events were promoting collaboration.

My instinct in the past would be to try and tidy things up. Rationalize it to hold everything together. But this time we didn’t.

We faced and named the contradiction. Acknowledged the policy was a holdover from the old system. And we framed it as transitional. We admitted the truth: we couldn’t change everything at once. It would’ve been overwhelming. Practically, emotionally, and organizationally.

And guess what? People understood and they were fine with it. Because we were clear, honest, and respectful of everyone’s capacity for change.

5. Surfacing the Old Is Mistaken for Slowing Down Change

I know it’s hard to hear. But here’s the thing: legacy patterns dissolve gradually.

If you don’t accept it, it will still linger — just beneath the surface, pulling people back. You end up drained and people’s trust erodes. Because everyone senses the gap between the new story and the lived experience.

Allowing the old to surface doesn’t slow change down. It initiates it. And it puts the old culture on a notice period. It gives it time to dissolve with dignity. In people’s nervous systems and in the culture DNA.

By naming the old patterns — without shame, without the rush to fix — you ground everyone in reality. And that makes you credible. Because you honor where you are in the timeline of change. Not rushing cultural death. But feeling the weakening pulse and working with it. Not against it.

Which brings me to the next lesson learned that I’ll unpack in the next post. A hint? Surfacing the old is one thing. But understanding where it comes from and discerning what’s still worth keeping is another.
