What You Don’t Know Is Leading You

“Leadership isn’t just about making decisions. It’s about knowing what you don’t know.”

It sounds obvious. But in practice, it’s one of the hardest things any leader faces: the limits of their own perspective.

We often define leadership through clarity, confidence, and decisiveness. But clarity without curiosity becomes tunnel vision. And decisiveness, without reflection, becomes recklessness.

In truth, it’s not what leaders know that defines them. It’s how they deal with what they don’t.

Blind Spots: The Stuff You Don’t Know You Don’t Know

Skill gaps are easy to admit. You can train for them, hire for them, or build around them. But blind spots? They catch you off guard. They shape decisions without you even realising they’re there.

They show up in familiar places:

A meeting where no one speaks up
A policy that hasn’t been questioned in years
A process where challenge used to exist and now doesn’t

You don’t know what you don’t know. That’s what makes blind spots dangerous.

Psychologists call this the Dunning-Kruger effect. The people who know the least often think they know the most. And the ones who actually know? They’re usually still listening.

Why This Matters More Than Ever

Leadership today is rarely built on titles alone. You work across boundaries. Lead in volunteer settings. Navigate complexity. These are environments where power isn’t imposed, it’s earned. Where influence matters more than control.

In those environments, ego is a liability. Certainty is fragile.

The best leaders I’ve worked with don’t try to have all the answers. They know how often they’ve been wrong before. They stay curious. They stay listening.

That’s the real danger of blind spots: not just what you miss, but what your confidence filters out.

How I Try to Catch My Own Blind Spots

No one’s immune to this. I’ve led in enough matrixed and voluntary roles to know that when people stop pushing back, you’re in trouble. Here’s what I try to practise:

1. Ask questions you don’t already know the answers to.
I try to ask: “What am I not seeing here?” And mean it. The Johari Window reminds us that others often see us more clearly than we see ourselves. If you’re never surprised by feedback, you’re probably asking the wrong people.

2. Pay attention to silence.
Silence is rarely neutral. If no one’s speaking up, I’ve learned not to assume they agree. If no one’s pushing back, you’re probably not hearing the full story.

3. Zoom out before you double down.
Ron Heifetz calls this stepping off the dance floor and onto the balcony. It’s about seeing the system, not just the issue. When everything feels urgent, I try to stop and ask, “Am I solving the right problem, or just reacting to the loudest one?”

4. Question the frame, not just the facts.
Argyris and Schön called this double-loop learning. You don’t just fix what’s broken. You ask whether your assumptions were wrong to begin with.

5. Stay suspicious of certainty, especially your own.
That includes mine. The more I’ve learned, the more I’ve realised how much I’ve missed. That’s not self-doubt. That’s awareness.

Blind Spots Live in Culture Too

Blind spots don’t just live in people. They live in culture.

In KPIs no one questions.
In meeting structures that reward repetition, not reflection.
In feedback loops that are there on paper, but not in practice.

If we don’t design challenge into the system, we end up building echo chambers. Then we wonder why nothing changes.

We spend a lot of time upskilling leaders in strategy, finance, delivery. But not nearly enough on awareness, listening, or ethical doubt.

If we built leadership pipelines that rewarded reflection as much as results, we might see fewer headlines and stronger teams.

You Can’t Eliminate Blind Spots. But You Can Refuse to Be Led by Them.

You’ll never see everything. That’s not the goal.

The goal is to build habits, teams, and cultures that catch what you miss.

So here’s the real leadership question:

Who’s telling you what you don’t want to hear? And how are you making sure they still feel safe to say it?

Theory in Practice

Here are a few models that shape my thinking:

Johari Window – self-awareness and perception gaps (Luft & Ingham, 1955)
Double-loop learning – questioning assumptions, not just actions (Argyris & Schön, 1978)
Dunning-Kruger effect – when confidence outpaces competence (Kruger & Dunning, 1999)
Adaptive leadership – seeing systems, not just symptoms (Heifetz, Grashow & Linsky, 2009)

If this resonates, challenges, or adds to your thinking, I’d love to hear your take.
