I was 23, sitting in my first real strategy meeting. The director turned to me and asked about market penetration rates in Southeast Asia. I had no idea. Zero. I don’t know.
But instead of saying those three simple words, I heard myself talking about “emerging trends” and “data suggests…” absolutely nothing.
I bullshitted my way through two minutes of corporate word salad. And my brain screamed at me to just stop talking.
That moment still makes me cringe. Not because I didn’t know the answer, but because I was so terrified of appearing ignorant.
We all do this. We’ve built entire personalities around avoiding the admission that we don’t know something.
The moment not-knowing becomes shame
Watch a four-year-old and you’ll see someone completely comfortable with ignorance. “Why is the sky blue?” “I don’t know, let’s find out!” They treat not-knowing as the starting point of adventure.
Then we send them to school.
Somewhere between kindergarten and college, “I don’t know” transforms from curiosity into failure. Raise your hand with a question and risk looking foolish in front of 30 peers. Stay silent and at least preserve the possibility that you might know.
I remember sitting in a quantum physics lecture in university, completely lost after the first ten minutes. The professor asked if everyone understood the wave-function collapse. Thirty heads nodded. Mine nodded too. Later in the canteen, I discovered half the class was equally confused. But we’d all performed understanding rather than admit confusion.
The academic system runs on this quiet pretense. Students fake comprehension. Professors, feeling pressure to appear authoritative, sometimes do too. Everyone protects everyone else’s illusion of knowledge.
When your job depends on knowing
The professional world actively punishes it.
A friend who’s a doctor once told me about her first year as a resident. A patient asked about a rare condition she’d only read about once in medical school. She could have said “I’m not sure, let me look that up and get back to you.” Instead, she gave a half-remembered explanation that was probably 60% accurate. She watched the patient’s face relax with trust, and felt simultaneously relieved and disgusted with herself.
“The patient needed confidence from me more than perfect information in that moment,” she said. “But I still wonder if I should have just been honest.”
This is the trap. Job interviews demand you “demonstrate expertise.” Client meetings needs projecting certainty. Performance reviews rarely reward the person who admits “I’m still figuring that out.” We’ve built professional structures where appearing knowledgeable matters more than the messy reality of actually learning.
I’ve watched colleagues talk authoritatively about topics they Googled five minutes earlier. I’ve done it myself. We’ve all done it. Because saying “I don’t know, but I’ll find out” feels like handing ammunition to whoever wants your job or credibility.
The confidence gap
Here’s what makes this particularly twisted, the people who know the least often feel the most certain.
The Dunning-Kruger effect is when you watch three YouTube videos about vaccines and suddenly feel qualified to argue with immunologists. When you don’t know enough to recognize complexity, everything looks simple.
Meanwhile, actual experts drown in uncertainty.
I once interviewed a climate scientist for a project. Every answer came with caveats, confidence intervals, acknowledgments of what the data couldn’t tell us. He sounded uncertain about everything. Then I spoke with a local blogger who’d read some contrarian articles. And he sounded absolutely sure the experts were wrong.
Guess whose interview sounded more convincing to people without scientific training?
We’ve created a perverse incentive structure where ignorance breeds confidence, and confidence wins attention. The person who admits doubt loses the room to the person who eliminates nuance.
The knowledge gradient nobody talks about
You learn something basic and suddenly you’re the expert among people who know less.
A parent explains gravity to their kid: “Things fall down because of gravity.” The kid’s satisfied. But then they ask why. And you remember something about mass and attraction. They ask why mass attracts. You mention Einstein and curved spacetime. They ask why mass curves spacetime.
Now you’re at the edge of your knowledge, but you’ve already established yourself as the authority. Admitting “nobody fully knows why” feels like betraying the confidence your child placed in you.
This happens everywhere. You can multiply numbers, so you help your niece with homework. Then she asks why multiplication works the way it does. You memorized procedures without understanding foundations, and now you’re trapped between admitting ignorance and making something up.
The universe itself seems designed to humble us this way. We’ve sent robots to Mars but can’t predict next month’s weather accurately. We’ve mapped human DNA but don’t fully know why you need sleep. And we’ve built quantum computers while still debating what quantum mechanics actually means.
Pick any field and you’ll find a horizon where human knowledge just stops. Physics can’t explain why the fundamental constants have their particular values. Mathematics proved (through Gödel) that some true things can never be proven. Neuroscience can measure brain activity but can’t quite explain consciousness.
The smartest people in these fields say “I don’t know” constantly. It’s everyone else who sounds certain.
Culture builds the prison
We mythologize people who had answers.
Think about how we tell Einstein’s story. We make it sound like he knew relativity was true, had a burst of genius, and the universe yielded its secrets. We skip the years of uncertainty, the mistakes, the times he doubted himself, the theories he proposed that turned out wrong.
This we do with every field. Scientists in movies have eureka moments. Doctors on TV diagnose rare conditions in 42 minutes. Leaders get celebrated for “decisive action,” not thoughtful uncertainty. We’ve turned the messy reality of learning into clean narratives about people who simply knew.
I fell for this mythology hard in my twenties. I thought competent adults had things figured out. Then I became an adult and discovered everyone’s improvising. Your doctor is making educated guesses. Your boss is hoping their strategy works. And your parents were terrified they were screwing you up.
Nobody knows what they’re doing as much as they pretend to. We’re all just trying not to get caught not-knowing.
The strange comfort of cosmic ignorance
Here’s what finally made it easier for me to say those three words. This happened after realizing how much humanity collectively doesn’t know.
We don’t know what 95% of the universe is made of (we just called it “dark matter” and “dark energy”). We don’t know if math is discovered or invented. Also, we don’t know what happened before the Big Bang, or if “before” even makes sense in that context. We don’t know why there’s something rather than nothing.
These aren’t gaps we’ll fill next year. They’re fundamental mysteries that humans can’t comprehend. We are just not built that way.
And yet, somehow, we still get up in the morning, build things, love people, make progress on what we understand. Ignorance doesn’t stop us. Pretending we’re not ignorant, in fact does.
What shifts when you let yourself not know
The first time I said “I don’t know” in a professional setting and didn’t try to fill the silence, I thought my credibility died. I was in a marketing meeting in 2018, someone asked about conversion optimization strategies for a platform I’d never used, and I just said, “I don’t know that platform well enough to give you good advice.”
The room didn’t gasp. Nobody wrote me off. Instead, someone who did know that platform jumped in, we had an actual useful conversation, and afterward my manager told me he appreciated that I didn’t waste everyone’s time pretending.
That moment rewired something in me.
Now when my nephew asks me why the sky is blue, I explain light scattering. When he asks why light scatters that way, I talk about wavelengths. When he asks why shorter wavelengths scatter more, I say “that’s where my knowledge stops, but we can look it up together.”
He doesn’t think less of me. If anything, he’s learning that not-knowing isn’t shameful. It’s just the current edge of understanding.
Good relationships work this way too. “I don’t know how to help you with this, but I’ll figure it out with you” builds more trust than fakeness. The best teachers create spaces where “I’m confused” is a contribution, not a confession. Research labs function because everyone’s explicitly searching for what they don’t know yet.
The people advancing human knowledge are comfortable with uncertainty. It’s the rest of us, further from the edge, who feel pressure to perform omniscience.
Unlearning the shame
Saying “I don’t know” is the first accurate thing anyone says about hard problems.
The trick is recognizing the difference between ignorance you should remedy (your own job responsibilities, facts you can easily learn) and ignorance that’s either inevitable (the frontiers of human knowledge) or acceptable (things outside your domain that you can find out if needed).
I still catch myself starting to bullshit when I don’t know something. The impulse runs deep. But now I pause, feel that moment of vulnerability, and let myself just say it: “I don’t know.” It’s relieving.
Sometimes I add “but I can find out” or “but here’s what I do know” or “let’s figure it out together.” Sometimes I just leave it there.
Either way, I’ve stopped treating my own ignorance like a secret that’ll destroy me if anyone discovers it. The universe is too big, knowledge is too vast, and human brains are too limited for any other outcome.
The only real difference is whether you admit it or spend your energy pretending otherwise.
I’m still figuring out which moments call for honesty and which call for confidence. I don’t have this solved. I’m not sure anyone does.
But at least now I can say that.
