I was maybe eight years into being a principal when a teacher asked me, in front of four other staff members in a hallway meeting, why enrollment projections for the next year didn't match what the district office had told her department. I didn't know the answer. I knew the general shape of school finance, I knew our building's numbers, but the specific discrepancy she was pointing at was outside what I'd actually verified. So I said the three words I'd spent years being trained, implicitly, never to say out loud in front of staff: "I don't know."
You'd have thought, from how my stomach dropped, that I'd confessed to something disqualifying. Somewhere along the climb from teacher to principal to superintendent, I'd absorbed an unspoken rule that the person in charge is supposed to have the answer, or at least a confident-sounding version of one, at all times. Admitting the gap felt like handing someone a weapon. What actually happened was smaller and stranger: the teacher nodded, said "okay, can you find out," and the meeting kept moving. Nobody's confidence in me collapsed. If anything, something in the room settled.
What Psychological Safety Research Actually Found
Years later I came across Amy Edmondson's research out of Harvard on team performance, the same body of work behind Google's well-known Project Aristotle study on what separates high-performing teams from average ones. The single strongest predictor wasn't talent, wasn't experience, wasn't even clear goals. It was psychological safety — whether people on the team believed they could take a risk, admit an error, or say "I don't know" without being punished or diminished for it. Here's the detail that reframed everything for me: that safety gets set overwhelmingly by the leader's own behavior, not by a policy or a poster in the break room. A leader who never admits uncertainty is, without meaning to, teaching everyone underneath them that uncertainty is dangerous to show. People learn that lesson fast, and then they stop bringing you the early warnings you actually need.
"Psychological safety describes a team climate characterized by interpersonal trust and mutual respect in which people are comfortable being themselves." — Amy Edmondson
Marcus Aurelius Knew This From the Other Direction
Marcus Aurelius ran an empire, which is a slightly bigger job than running a school district, and he wrote to himself constantly about the difference between the appearance of competence and the substance of it. In the Meditations he reminds himself repeatedly to say what he actually believes is true and let the outcome be what it is, rather than performing a certainty he doesn't have to protect his standing. He wasn't writing leadership advice for other people. He was correcting his own instinct — the same instinct I had in that hallway — to reach for a confident answer instead of a true one. If the most powerful man in the Roman world needed to remind himself of this daily, I don't feel quite as bad that it took me eight years as a principal to learn it.
Let's Be Honest About Why We Fake It
The real reason most of us bluff isn't that we think we'll fool anyone for long. It's that we're afraid the gap in our knowledge will get read as a gap in our worth. Those aren't the same thing, but under pressure they feel identical, and so we reach for confident-sounding language to cover a hole we could have just named. I did this for years before that hallway conversation, and what I mostly accomplished was teaching my staff that I wasn't a safe place to bring their own uncertainty — which meant I found out about real problems later than I should have, every time.
How I Practice This Now
I say it plainly, without padding. Not "that's a great question, let me circle back on the various factors" — just "I don't know, let me find out." The padding is usually the bluff trying to sneak back in.
I follow it with a real next step. "I don't know" without a plan to find out is just an admission. Paired with "I'll have an answer by Thursday," it's leadership.
I say it first, before someone has to catch me in it. Volunteering the gap costs almost nothing. Getting caught pretending you didn't have one costs the whole room's trust at once.
That teacher in the hallway, incidentally, became one of the people I trusted most for the rest of my time in that building — partly, I think, because she'd watched me not know something and stay standing. That's a stranger kind of credibility than having all the answers. It's also the only kind that's actually true.
Where are you currently bluffing confidence you don't have — and what would it cost you, honestly, to just say "I don't know" out loud this week?
