Albert Einstein was five years old and sick in bed when his father placed a small magnetic compass in his hands.

Young Albert turned it over, shook it, tilted it. No matter what he did, the needle returned to north. Something invisible was guiding it. Something that could not be touched, only sensed. 

Years later, Einstein described that compass as one of the defining experiences of his childhood. It awakened a realization that would shape his life’s work: beneath the visible world were hidden forces governing everything.

He later wrote that the experience left him with the conviction that something deeply hidden had to be behind things.

That sense of wonder never left him.

At sixteen he began imagining what it would feel like to chase a beam of light through space. There was no established academic framework, no accepted methodology, and certainly no practical reason to pursue it.

But he simply kept thinking.

For years he returned to the question, turning it over in his mind the way he had once turned over that compass. He examined it from every angle, refusing to abandon it simply because it resisted easy answers.

That question eventually became the foundation of the theory of special relativity. Einstein later explained his process with characteristic simplicity: "I have no special talent. I am only passionately curious."

It wasn’t false modesty. It was his explanation for discovery itself.

Whether it was the compass, the beam of light, or the decades spent pursuing questions that appeared unproductive to everyone else were not distractions from his work. They were his work.

Curiosity, sustained long enough and pursued deeply enough, becomes insight.

So what happens to that mechanism as we become more experienced?

In 2002, Yale psychologists Leonid Rozenblit and Frank Keil demonstrated something remarkable. They asked participants to rate how well they understood everyday objects like flush toilets, bicycle locks, sewing machines, and zippers. Most people gave themselves high scores.

Then the researchers asked them to explain, step by step, exactly how each object worked. Almost no one could. When participants rated their understanding a second time, their confidence and their scores dropped.

Rozenblit and Keil called this the Illusion of Explanatory Depth: our tendency to believe we understand complex things far better than we actually do.

The most surprising finding was that the illusion is strongest with the things people encountered every day and used constantly. These were the very things they understood least, while believing they understood them most.

Familiarity creates the feeling of knowledge without requiring the work of understanding.

That illusion becomes especially dangerous for accomplished people.

Experience creates competence. Competence builds confidence. But confidence, left unchecked, turns into certainty. Over time, certainty replaces curiosity.

Every success reinforces what you already believe. Every year spent mastering a field makes fewer questions seem worth asking, because the answers start to feel obvious. 

Einstein spent his life resisting that temptation.

He never confused experience with complete understanding. He kept asking questions that others dismissed as obvious, because he knew that every breakthrough begins where certainty ends. That is the rarest form of courage in any accomplished life: the willingness to remain a student of the very things you have mastered. 

The greatest threat to progress is not ignorance, but the belief that there is nothing left to discover. 

The needle is still moving. The only question is whether you still have the wonder to follow it.

THE SHIFT

Here are the shifts to make:

Expertise → Inquiry
Expertise explains what you know. Inquiry reveals what you don’t. Every breakthrough begins by exploring what is yet to be understood. Don’t let expertise become certainty. Use it to ask better questions.

Confidence → Calibrated Uncertainty
Confidence trusts your answers. Calibrated uncertainty tests them. Better decisions begin by questioning the assumptions you hold most tightly. Make it a habit to pressure-test what you’re most certain is true.

Information → Wonder
Information explains what is. Wonder imagines what could be. The future is created by unanswered questions. Don’t wait to feel curious. Make wonder a discipline by questioning what seems most familiar.

THE STRATEGY

Keep a Questions List.
Write down every question that puzzles you. Resist the urge to consult AI, Google, or a colleague. Choose one each day and spend 15 minutes thinking. Better questions lead to better thinking.

Challenge One Assumption.
Pick one thing you believe is true about your work, your team, or your business. Then ask: “What would have to be true for the opposite to be true?” You don’t have to change your mind. You only have to challenge it. 

Explain It Simply.
Choose one idea you believe you understand and explain it to someone else in plain language without jargon or buzzwords.  If you get stuck, you’ve found something worth learning more about.

THE STACK

Use AI as a thinking partner to expose blind spots, challenge assumptions, and deepen perspective. Copy this prompt:

I am a [your role] at a [company type] in the [industry] industry.

I want to pressure-test a belief I currently hold about [my business / my team / my strategy / my market / my career / my own value].

I am going to explain it to you out in plain language, as if you know nothing about my field. Your job is not to validate me, agree with me, or solve the problem. Your job is to make my thinking better.

As I explain my reasoning:

* Ask me “Why?” whenever I make a claim without evidence.
* Stop me whenever I use jargon, buzzwords, or vague language, and ask me to explain it simply.
* Challenge assumptions that I treat as facts.
* Point out logical leaps, contradictions, or circular reasoning.
* Ask me what evidence would change my mind.
* If I reach a conclusion too quickly, slow me down with better questions instead of answers.
* If you notice I’m answering a different question than the one I started with, call it out.

When I finish, give me four things:

1. The three weakest parts of my reasoning and why they are weak.
2. The assumptions I’m making that deserve to be tested.
3. The one question I’m avoiding that would most improve my thinking if I answered it honestly.
4. Five follow-up questions that would deepen my understanding before I make a decision.

Do not let me mistake confidence for clarity. Hold me to actual understanding. Your goal is not to help me sound smarter. Your goal is to help me think better.

Curious: The Desire to Know and Why Your Future Depends On It
By Ian Leslie

Leslie makes an argument that most people have the wrong model of curiosity. They treat it as a personality trait you either have or don't, rather than a practice that atrophies without deliberate cultivation.

His research draws on psychology, neuroscience, and the history of innovation to show that the leaders, scientists, and artists who sustain curiosity longest are the ones who learned to protect it from the thing that kills it most reliably: the comfort of already knowing.

I love this book for one specific idea: "diversive curiosity" versus "epistemic curiosity" which is the difference between being attracted to novelty and being willing to go deep into difficulty. The second kind is the one most at risk the more accomplished you become.

THE SIGNAL

The Exit Interview Podcast

In a world that rewards expertise, curiosity is becoming a competitive advantage. In my podcast conversation with hosts Shana Ayabe and Kisha Imani Cameron, we explored why the AI age is about embracing impermanence, shedding ego, and navigating change as explorers. This episode is an invitation to challenge assumptions, think more deeply, and rediscover the questions that lead to real breakthroughs.

What are you so certain about that you’ve stopped questioning it?

Until next time...stay curious!
