The Curse of Knowledge Is Ruining Your Leadership (And You Don’t Even Know It)

The biggest communication problem isn’t what you’re saying. It’s what you’re assuming everyone already knows.

Let me tell you about a simple experiment that will change how you communicate forever.

Take a well-known song. Something everyone knows. “Happy Birthday.” “Twinkle Twinkle Little Star.” “Jingle Bells.”

Now tap the rhythm on a table. Just the rhythm. No humming. No singing. Just tapping.

Then ask the person next to you to guess the song.

You’ll be shocked.

Because in your head, you can hear every note. Every word. The melody is crystal clear. You’re practically singing it while you tap.

But to the person listening? It’s just noise.

Random taps on a table. No melody. No context. No song.

And you’ll be frustrated. Because it seems so obvious to you.

That frustration? That gap between what’s in your head and what’s landing in theirs?

That’s the Curse of Knowledge.​

And it’s running your leadership, your communication, and your relationships—whether you realize it or not.

What the Curse of Knowledge Actually Is

The Curse of Knowledge is simple:

Once you know something, you can’t unknow it.

And because you can’t unknow it, you assume everyone else knows it too.

You assume your team understands the context behind your decision. They don’t.

You assume your partner knows what you need. They don’t.

You assume your apprentice knows the basic safety habits. They don’t.

You assume the song is obvious. But all they hear is tapping.

I tried the tapping experiment with the guys at work years ago. It was hilarious.

I was tapping out “Happy Birthday” as clearly as I possibly could. In my head, I could hear every word, every note.

The guys had absolutely no idea what I was tapping.

They kept guessing wrong. Getting more confused. More frustrated.

And I kept thinking: How can you not hear it? It’s so obvious.

That’s the curse. The moment you know something, it feels obvious. Universal. Like everyone must know it.

But they don’t.

Where I First Ran Into This as a Leader

When I became a journeyman and then a foreman, I ran into the Curse of Knowledge constantly.

After years—even decades—in the trade, there were just certain things you do and don’t do.

• Keep your head on a swivel.
• Always know where the live circuits are.
• Never assume a wire is dead until you’ve tested it yourself.

These weren’t rules I had to think about anymore. They were automatic.

Instinctive. Common sense.

But to a first-year apprentice? A brand new young adult who’d never been on a jobsite?

None of it was common sense. None of it was automatic.

They didn’t know what they didn’t know.

And I’d get frustrated. “How does he not know to keep his head on a swivel? It’s obvious.”

But it wasn’t obvious. Not to him.

It was obvious to me because I’d been doing it for twenty years. Because I’d learned it the hard way. Because it had been drilled into me by foremen who’d learned it the hard way before me.

He hadn’t had any of that. He was a blank slate.

And the moment I remembered that—the moment I asked myself, “What was it like when I was a first-year apprentice and didn’t know shit?”—everything changed.

I could meet him where he was. Not where I was.

And that’s when I could actually help him learn and succeed.

The Same Thing on the Mat

The same lesson keeps showing up in martial arts.

In hapkido back in the day. And now in BJJ.​

I’ve been training BJJ consistently for almost two and a half years. And I’ve been finally integrating some of the skills I’ve been struggling with for a while.

And when I roll with new white belts now, I can feel and see exactly what the upper belts had been telling me.

I can feel the white belt’s tension. Their panic. Their instinct to muscle through instead of flow. Their inability to see the position they’re in because they’re too focused on the position they want to be in.

I was that white belt. Not long ago.

And because I remember what it felt like—because I haven’t forgotten the confusion, the frustration, the feeling of being completely lost—I can meet them where they are.

I can offer them the lessons I’ve been learning. The what and the why behind them.

Not from the perspective of someone who’s always known. But from the perspective of someone who recently didn’t know.

And that’s the difference between a teacher who instructs and a teacher who connects.

Why the Curse of Knowledge Destroys Leadership

Here’s how the Curse of Knowledge shows up in leadership—and why it’s so destructive:

1. You stop explaining the “why.”

When you know something deeply, the reasoning behind it feels obvious. So you stop explaining it.

You just give the instruction. “Do it this way.” “Follow this process.” “Use this approach.”

But without the why, people can’t adapt when circumstances change.

They can follow the instruction in the exact situation you described. But the moment something is slightly different, they’re lost.

Because they know the what. But not the why.

2. You assume context that doesn’t exist.

You make a decision and communicate it to your team. But you don’t share the context behind it—the information you considered, the alternatives you rejected, the reasoning you followed.

Because all of that context is so present in your mind that you assume it’s present in theirs.

It’s not.

And without that context, your decision seems arbitrary. Or wrong. Or confusing.

And your team either doesn’t follow it, or follows it blindly without understanding—which means they can’t execute it well.

3. You lose patience with beginners.

When you’ve mastered something, beginner mistakes seem inexplicable.

• “How can they not see that?”
• “Why would they do it that way?”
• “This is so basic.”

But it’s only basic to you because you’ve already learned it.

To them, it’s new. It’s complex. It’s overwhelming.

And your impatience—born from the Curse of Knowledge—makes them feel stupid instead of supported.

Which makes them less likely to ask questions. Less likely to admit mistakes. Less likely to learn.

4. You communicate in shorthand.

You develop jargon. Shorthand. Assumptions about shared vocabulary.

And you forget that not everyone speaks your language.

The new team member doesn’t know what you mean by “keep your head on a swivel.”

The new client doesn’t know your industry terminology.

The new student doesn’t know the names of the positions.

You’re tapping the rhythm. They’re hearing noise.

5. You stop asking if people understand.

Because you assume they do. Because it’s obvious to you.

And so the gap between what you think you communicated and what they actually received grows wider and wider.

Until something breaks. A mistake. A miscommunication. A failure.

And you’re shocked. Because you thought everyone was on the same page.

How to Break the Curse

Here’s how you overcome the Curse of Knowledge and become a more effective leader and communicator:

Step 1: Remember what it was like to not know.

This is the foundational step. And the hardest.

You have to actively reconstruct the experience of being a beginner.

What was it like when you were a first-year apprentice? When you were a white belt? When you were new to this industry, this skill, this role?

What confused you? What did you assume you should know but didn’t? What did you wish someone had explained?

The more vividly you can remember that experience, the better you can connect with the people who are living it now.

Step 2: Explain the why, not just the what.

Every instruction you give, every decision you make, every process you establish—explain the reasoning behind it.

Not just “do it this way.” But “here’s why we do it this way.”

Because when people understand the why, they can adapt the what to new situations. They can make good decisions when you’re not there. They can teach others.

The why is what transforms followers into leaders.

Step 3: Check for understanding—really.

Don’t ask “Does everyone understand?” That question is useless.

People will nod even when they don’t understand. Because admitting confusion feels like admitting failure.

Instead, ask them to demonstrate. To explain it back to you in their own words. To apply it to a new situation.

“Can you show me how you’d handle this?” is a much better question than “Do you understand?”

Step 4: Eliminate jargon with new people.

When you’re communicating with someone new—a new team member, a new client, a new student—assume zero shared vocabulary.

Explain every term. Define every concept. Use plain language.

Not because they’re stupid. But because they haven’t had the years of context that made these terms second nature to you.

Step 5: Slow down.

The Curse of Knowledge makes you move too fast.

Because in your head, you’ve already processed all the steps. You’ve already connected all the dots. You’re already at the conclusion.

But they’re still at the beginning.

Slow down. Break it into smaller steps. Check in at each step before moving to the next.

The pace that feels slow to you is often the pace that actually works for them.

Step 6: Welcome questions as intelligence, not ignorance.

When someone asks a question that seems obvious to you, resist the urge to be impatient.

That question is a gift.

It’s showing you exactly where your communication failed. Where you assumed knowledge that didn’t exist. Where you tapped the rhythm without sharing the song.

Thank them for asking. Answer thoroughly. And then ask yourself: How do I communicate this better next time so the question doesn’t need to be asked?

Step 7: Stay connected to your beginner self.

This is an ongoing practice, not a one-time fix.

Keep doing things you’re bad at.

Learn a new skill. Take a beginner class. Put yourself in situations where you’re the white belt.

Because the experience of being a beginner keeps you connected to what it feels like to not know.

And that connection is what makes you a great teacher. A great leader. A great communicator.

The Rising Tide

Here’s the beautiful thing about breaking the Curse of Knowledge:

When you can meet people where they are—when you can communicate clearly, explain the why, and connect with the beginner’s experience—you don’t just help them.

You help everyone.

Because when the new white belt understands the position, they become a better training partner for everyone.

When the first-year apprentice understands the safety habits, the whole jobsite is safer.

When the new team member understands the reasoning behind the process, the whole team executes better.

Rising tides raise all ships.

And the tide rises when leaders break the Curse of Knowledge and communicate in a way that actually lands.

Your Challenge to Free Yourself from the Curse

Here’s what I want you to do this week:

Try the tapping experiment.

Pick a song. Tap the rhythm. Ask someone to guess.

Feel the frustration when they can’t.

Then ask yourself: Where am I doing this in my leadership? In my relationships? In my communication?

Where am I tapping the rhythm and expecting people to hear the song?

Then pick one area. And start sharing the song.

Explain the why. Slow down. Check for understanding. Welcome questions.

And remember what it was like to be an empty cup.

Because only from that place can you truly fill others.

That's All I Have to Say About That

The Curse of Knowledge is running your leadership, your communication, and your relationships.

Not because you’re a bad communicator. But because you’re a knowledgeable one.

And knowledge, without the awareness of what it’s like to not know, creates a gap between you and the people you’re trying to lead.

The fix isn’t to know less. It’s to remember more.

Remember what it was like to be a first-year apprentice. A white belt. A beginner.

And communicate from that place.

Not from the top of the mountain. But from the path you walked to get there.

Because that’s where the people you’re leading are standing.

And they need you to meet them there.
