Can you remember a time when a door opened in your mind? A moment when your perception changed so completely that you could not go back to the way you saw things before?

Something shifted. You saw what you had not seen. And once it was seen — really seen — the old version of reality no longer quite fit.

Here is what I want you to know about that moment: it was not an accident. It was not a breakdown. It was not a sign that something was wrong with you. It was a sign that something was becoming more right.

That kind of shift matters when you lead. Not because leaders need to have all the answers — honestly, that is usually part of the problem. It matters because every decision you make is filtered through what you are able to see, what you have learned to ignore, and what you have quietly decided is not worth questioning anymore. And most of us decided that without realizing we were deciding anything at all.

Most of us were handed a map and told it was the world.

We were taught to measure, to trust what could be quantified, and to dismiss what could not. If you could put it in a spreadsheet, it counted. If you could not, it became suspect. This is not anyone's fault. This is what the culture handed us, and most of us took it without thinking twice — because why would we think twice about the map? The map was just how you got around.

And to be clear: the map is not wrong. It has built extraordinary things. It has helped us understand, predict, create, solve, scale, and prove. I have nothing against the map.

This experience is not asking you to abandon data, logic, experience, or good judgment. It is asking something much more interesting than that. It is asking you to inspect the lens underneath all of it. The assumptions you may be using without noticing. The shortcuts that once protected you but may now be costing you. The questions you stopped asking because the answer seemed obvious, impossible, or too expensive.

Because the most important things — the things that actually drive decisions, creativity, leadership, meaning, trust, and momentum — do not always survive being broken into parts. They live in the relationship between parts. In the field between people. In the signal that arrives before the logic catches up. In the thing everyone senses before anyone says it out loud.

You already know this. Some part of you has always known this.

Analytics. Data. Process. Strategy decks with forty-seven slides. The illusion is that if we just have enough information we'd finally know what to do.

Here is what the data actually shows about how much we trust the data.

Even the people building the map don't trust it. The people using the map don't trust it. And the people paying for the map are quietly going with their gut anyway.

This is not a failure of data. It is the people using the map acknowledging — in behavior if not in words — that the map is limited.

Every map has a mapmaker. Every mapmaker has a perspective. Every perspective has a bias. The question is not whether the bias exists — it always does. The question is whether it is acknowledged.

Humans are behind every experiment. Repeating and measuring with the same assumptions every time can produce consistent results that are consistently missing something.

The map is not wrong. The map is simply unfinished. And it does not tell you it's unfinished. That is the only dangerous thing about it.

In college I drove my professors crazy. I tried to write out all of my presuppositions at the start of every paper. I thought it was the only honest way to write anything. If I didn't name what I was assuming before I started arguing, how could anyone — including me — trust the argument?

They found it unusual. I found everything else dishonest. I've since given up that annoying practice.

But that instinct hasn't left. It's what this entire experience is built on. Before we can examine what we believe, we have to be honest about what we're already assuming — the presuppositions we carry into every conversation, every decision, every relationship — without knowing we're carrying them.

Give this a minute. We all have thousands of questions we've stopped asking. Some because the answer seems obvious. Some because the answer seems impossible. Some because asking them feels dangerous.

Here is a spectrum. From the questions whose answers are so certain you never think about them, to the ones so large you've surrendered them entirely.

Notice where you stopped. Notice which ones made you uncomfortable. Notice which ones you answered immediately — and whether you actually know the answer or just stopped asking.

The map is limited. We established that.

But there is something closer to home worth looking at. Not just the cultural lens we all inherited. Your lens. The specific shortcuts, assumptions, and inherited beliefs that are running inside you right now. Making decisions you think you are making. Filtering what you even consider possible.

I was hired at Tableau to help close the adoption gap between analysts and the business. On the surface the work looked practical. Help people use data. Help analysts communicate value. Help business leaders stop treating dashboards like someone else's job.

But that was not the real learning. The real learning was watching what happened when people stopped arguing over the map and started seeing the lens they were using to read it.

Analysts were not just missing business context. Business leaders were not just resisting data they didn't trust. They were often operating from entirely different assumptions about what counted as truth, what created value, and how we know what we know — aka epistemology, six syllables, and worth every one of them.

An assumption is something you're treating as true right now — in this situation, this relationship, this organization — that you've never actually tested. It's the ground you're building on without checking whether it's solid.

The costly ones aren't the obviously wrong assumptions. Those get corrected. The costly ones are the reasonable-sounding ones — the ones that have never been tested because they seem too obvious to test.

Your brain makes approximately 35,000 decisions a day. To manage that volume it builds shortcuts. Mental rules that compress experience into instant responses.

The shortcuts are not the problem. The problem is that most of them were formed before you had the capacity to choose them. They arrived from family, from culture, from the era you were born into, from a single painful experience that became a permanent rule. They were installed before anyone asked your permission.

A few worth sitting with:

There is something deeper than assumptions. Deeper than shortcuts. Something that shapes both of them without anyone noticing.

The philosopher Francis Schaeffer described it this way: most people catch their presuppositions from their family and surrounding society the way a child catches the measles.

Not chosen. Caught. Running invisibly. Making decisions.

A presupposition is the assumption underneath the assumption. The thing you believe so completely you have never needed to question it. It does not feel like a belief. It feels like reality.

What do you believe so completely that you have never questioned it?

Consider what is already installed. Darwin gave us survival of the fittest — and now it shapes how we think about competition, weakness, and who deserves to succeed. Freud gave us the idea that what drives us is largely unconscious — and now it shapes how we interpret motivation and behavior. Dewey gave us a philosophy of education centered on experience over memorization — and now it shapes what we believe intelligence actually is. Keynes gave us frameworks for government intervention in failing economies — and now they shape what we believe is possible for growth and stability.

You may not have chosen any of those frameworks. You caught them. And now they are loaded into your thinking, quietly deciding what feels possible, what feels worth questioning, and what feels settled.

Dave Breese wrote about seven thinkers whose ideas still shape the world long after their deaths — ideas people subscribe to without knowing it, keeping the philosophical grave open for men who died generations ago.

But the presuppositions worth examining are not only the philosophical ones. They are the personal ones. The ones about what you deserve. What someone like you is capable of. What strength looks like. What it means to ask for help. What success is supposed to look like — and who gets to have it.

Here is the most costly reason questions stay stopped. Not because the answer seems obvious. But because asking might cost you something you cannot afford to lose.

Belonging.

The family that holds a certain belief. The organization that operates on certain assumptions. The culture that has decided certain things are settled and certain people who question them are difficult, naive, disloyal, or outside.

The brain registers that risk the same way it registers physical pain. Research on social exclusion shows it activates the same neural regions as physical injury. Belonging is not a preference — it is a survival mechanism woven into the architecture of being human.

There is a difference between a question that is closed and one that is being held. Some stopped questions are held by conscious choice — love, timing, protecting someone who matters. Those deserve to be honored.

The same thing happens inside teams. A question stops being asked because asking it might cost too much. Not legally. Not officially. Not in the values statement. Socially. Someone might feel betrayed. Someone might lose face. Someone might feel exposed. Someone might pull away. Someone might punish the truth without ever admitting they punished it.

So the team adapts. The question gets softened. The concern gets delayed. The meeting moves on. The workaround becomes normal. And eventually, people stop experiencing the misalignment as something to resolve. They experience it as reality.

This is just how leadership works. This is just how this team communicates. This is just how decisions get made here. This is just how much honesty the room can handle.

That belief may be understandable. It may even have protected something for a while. But it also has a cost. Because one of the most expensive assumptions inside a company is the belief that real alignment is not possible — that a certain level of misalignment simply has to be tolerated because that is reality.

Maybe perfect alignment is not possible. But that is not the same as saying this level of misalignment is inevitable.

If you're curious what this kind of misalignment might be costing your organization — there's a simple calculator for that.
