The Danger of a Small Sample Size

“Wait… you’re doing an Executive MBA?”

The question usually lands somewhere between surprise and confusion. Not hostile, not dismissive, just slightly disoriented, as if two parts of my life don’t quite belong in the same sentence. Opera singer and business school seem, for some people, to exist on opposite ends of an invisible spectrum. The creative and the analytical. The artist and the executive.

What’s particularly interesting is that the reaction most often comes from people who’ve known me for years, who’ve watched performances, followed projects, maybe even felt close to the arc of my artistic life, but who have only ever known me inside that one identity. They know the singer. They don’t yet know the rest.

So when I mention financial modeling or systems thinking or organizational strategy, there’s a brief recalibration. A moment where the narrative they’ve held about me has to stretch.

I don’t take offense. I actually find the reaction fascinating. What interests me isn’t the assumption itself, but how quickly it forms and how durable it becomes. How effortlessly the mind assembles a story about what “fits” and what doesn’t. Most of us are rarely aware of the moment when a limited set of observations solidifies into something that feels like truth. It happens quietly. A few data points, a handful of experiences, a cultural shorthand, and suddenly we have a conclusion that feels stable, even obvious.

There’s something deeply human about that impulse. We’re wired to look for patterns. We prefer narratives that reduce complexity into something manageable. But what we call clarity is often just familiarity, repeated enough times to feel certain.

And that certainty, especially when it’s built on a narrow base of experience, has more influence than we realize.

What’s happening in those moments of surprise isn’t actually about me at all. It’s about how the mind economizes.

We don’t experience the world in full resolution. We experience fragments. A few interactions. A handful of examples. A story repeated often enough that it begins to feel representative. From that limited exposure, we build a working model. It’s efficient. It allows us to move quickly. It keeps us from having to re-evaluate every person, every situation, every time.

Psychologists sometimes refer to this tendency as single story bias. We take one narrative, or one dominant pattern, and let it stand in for the whole. Not because we’re malicious. Not because we’re careless. But because the brain prefers coherence over complexity.

The problem is that coherence built on limited data feels indistinguishable from truth.

If most of your exposure to opera singers has been through a certain lens, then “opera singer” becomes shorthand for a personality type. (You know you’ve got some notions around “opera singer” as a type!) If your experience of executives has followed a narrow arc, then “executive” begins to carry an entire personality profile with it. If you’ve not seen results from a “coaching investment” - you see where I’m going. One story stands in for many. One slice becomes the whole.

The danger isn’t that we form impressions. The danger is how quickly those impressions harden.

Over time, they stop feeling like impressions and start feeling like facts. We forget the smallness of the sample size that produced them. We forget how partial our vantage point actually was. And the conclusion, once formed, becomes self-reinforcing. We see what confirms it. We overlook what contradicts it.

This is where certainty begins to grow roots.

Not loud certainty. Not argumentative certainty. Just the quiet kind that settles in and says, “This is how it is.”

And that quiet certainty shapes more than we realize.

Certainty, when it hardens too quickly, behaves like a destructive natural force.

Not dramatic. Not explosive. But persistent.

It compresses.

It takes something expansive and presses it into a smaller frame. Complexity gets squeezed until it fits the existing narrative. Anything that resists that frame is either trimmed away or ignored. Over time, what remains feels clean and obvious, but it has been shaped under pressure.

Certainty reduces.

Reduction always removes something. It pares away contradiction. It eliminates tension. It strips the rough edges that might have required us to think more deeply or look again. The landscape becomes smoother, simpler, easier to navigate. It also becomes less alive.

Certainty closes pre-emptively.

Before a question has fully opened, it is answered. Before a person has fully revealed themselves, they are categorized. Before a possibility has had room to breathe, it is evaluated and filed away. Curiosity cannot survive in an environment where everything is already decided.

And this is where the violence lies.

Not in harm, but in force.

The force of premature conclusion.
The force of narrative rigidity.
The force of saying “this is what it is” when the data set was never large enough to justify that claim.

A destructive natural force does not need intention to alter terrain. It only needs repetition. Certainty, repeated and unexamined, reshapes what we are able to see. It narrows the shoreline of possibility without announcing that it is doing so.

By the time we notice, the view is smaller.

That is the violence.

If certainty can reshape how we see others, it is even more powerful in how it shapes how we see ourselves.

Because the single story bias does not stop at categories like “opera singer” or “executive.” It turns inward.

One failed audition becomes “I’m not actually that talented.”
One difficult relationship becomes “I’m bad at relationships.”
One season of uncertainty becomes “I’m not leadership material.”

A small sample size, repeated internally, hardens into identity.

And once identity calcifies, the violence intensifies.

Not because we are attacking ourselves. But because we stop allowing expansion. We compress who we are into the narrowest coherent version. We introduce ourselves from that compressed place. We make decisions from that compressed place. We evaluate our potential from that compressed place.

For years, I introduced myself as an opera singer.

Not because it was untrue. It was deeply true. But it was singular. And singularity, when held too tightly, becomes confinement.

When my identity began to expand, my technique expanded with it. When I stopped holding myself to one definition, my voice stopped operating inside such a narrow frame. And once that frame loosened, I could see other capacities that had been present all along. Coaching. Systems thinking. Pattern recognition. Architecture.

None of those appeared out of nowhere.

They had simply been outside the story I was certain about.

The most insidious form of certainty is the one that says, “This is who I am,” when what it really means is, “This is the version of me I can mentally articulate.”

It is the identity that fits inside language. The one that makes sense. The one that can be explained quickly and cleanly. The one that doesn’t require contradiction or expansion or mystery.

Anything that doesn’t yet have language tends to get excluded.

If I can’t describe it clearly, it must not be real.
If it doesn’t fit the narrative I’ve already told, it must not belong.

So we remain loyal to the story that is easiest to defend.

And slowly, without realizing it, we compress ourselves into the shape of that story.

This is where the distinction between certainty and certitude becomes more than semantics.

Certainty needs reinforcement. It seeks confirmation. It scans for agreement. It wants the story to hold. When threatened, it tightens. When questioned, it defends. Its stability depends on the narrative remaining intact.

Certitude is different.

Certitude does not require the story to be airtight. It does not panic when new information appears. It does not demand consensus. It has a different center of gravity.

Certitude settles.

It does not collapse complexity in order to feel stable. It allows complexity and remains grounded anyway. It does not rush to articulate itself fully. It does not insist on being impressive. It simply recognizes what is true and stands there.

Where certainty compresses, certitude holds.

Where certainty closes prematurely, certitude stays available.

Where certainty reshapes the terrain to protect the story, certitude is willing to let the story evolve.

And when we begin to recognize the difference, something subtle shifts. We can feel when we are defending a narrative and when we are standing inside something quieter, heavier, more grounded.

The violence of certainty begins to lose its grip the moment we no longer mistake it for clarity.

I don’t mean to argue semantics here, or split hairs for the sake of it. But the distinction between certainty and certitude turns out to matter more than it first appears.

Certainty lives primarily in the mind. It looks for reinforcement. It feels steadier when there is agreement, when the logic is airtight, when the narrative can be defended from multiple angles. When something challenges it, it tends to tighten. It gathers more evidence. It rehearses its case. Its stability depends on the story remaining intact.

Certitude operates from somewhere else entirely.

It does not need the story to be perfect in order to stand. It does not rush to secure consensus or anticipate objections. It does not collapse under the presence of new information. Instead, it carries a kind of grounded weight. It recognizes something as true without needing to broadcast it or prove it. There is often nothing dramatic about it. In fact, it can feel almost underwhelming compared to the urgency of certainty.

Where certainty reshapes the terrain to protect the narrative, certitude allows the terrain to shift without losing its footing. It does not compress complexity in order to feel stable. It remains present within complexity.

The difference is subtle, but once you feel it, it becomes unmistakable. One is rigid and defensive, even when it appears confident. The other is quiet and self-referencing, even when it cannot yet be fully articulated.

And that distinction determines whether we are defending a story about who we are, or standing inside something truer that is still unfolding.

If the violence of certainty reshapes the terrain of how we see others, and if it compresses who we are into the version we can most easily articulate, then the real question is not whether we are certain about something.

The question is whether that certainty has been examined.

It is remarkably easy to mistake familiarity for truth. It is remarkably easy to confuse coherence with completeness. A story that makes sense can still be partial. An identity that feels stable can still be unfinished.

The mind prefers what it can categorize. It prefers what it can explain. It prefers what it has already rehearsed. But there is often more happening beneath that layer than we allow ourselves to see.

When someone looks surprised that I am pursuing an Executive MBA, what they are responding to is not contradiction. It is expansion. Their existing story about me simply did not include that dimension. It had not yet needed to.

The more uncomfortable question is this: where have I done the same thing to myself?

Where have I decided too quickly who I am?
Where have I stayed loyal to a narrative because it was clean and defensible, even if it was incomplete?
Where have I allowed the version of me I can explain to stand in for the version of me that is still emerging?

Certitude does not demand that we abandon identity. It simply asks that we stop finalizing it prematurely.

It asks us to notice when we are compressing, and when we are standing.

It asks us to feel the difference.

Where have you mistaken your slice for the whole?

And what might be waiting just beyond the edge of that story?
