The More You Know, the Less You Speak

Early in my career, I believed competence announced itself. I thought knowledge needed volume, that confidence required projection, and that leadership meant having an answer for everything; preferably first and loud. Time, failure, and most importantly, experience cured me of that illusion. Experience has a way of sanding down the rough edges of certainty until what remains is quieter and more deliberate.

There’s a reason the most seasoned professionals in a room tend to speak last, or not at all.

Psychologists David Dunning and Justin Kruger put a name to a pattern many of us had already witnessed long before it was studied: the Dunning–Kruger Effect. In short, people with limited knowledge in a domain often overestimate their competence, while those with genuine expertise tend to underestimate theirs.

Experience Changes Your Relationship With Certainty

This effect isn’t theoretical: it’s operational.

We’ve all seen it: the loudest leader in the conference room, the junior leader who just finished a school or certificate program or read a new subject-matter-expert book, and now feels compelled to correct everyone within earshot, the leader who confuses confidence with competence. They speak often, speak forcefully, and speak with certainty.

Real experience introduces friction. It teaches you that every plan survives contact with reality for about five minutes, that second- and third-order effects matter, and that certainty gets teams in trouble. Once you’ve watched a “textbook solution” collapse under pressure, you learn to respect nuance.

That’s when your volume drops.

Seniority Should Increase Curiosity, Not Decrease It

The most capable leaders I’ve served under didn’t dominate conversations. They asked questions. They listened. They let junior leaders talk themselves into clarity or into revealing what they didn’t understand.

In combat, speaking less is often a survival skill. The experienced patrol leader doesn’t narrate every thought. The seasoned non-commissioned officer (NCO) doesn’t feel the need to prove he’s in charge every minute. He observes, processes, and intervenes only when necessary. He knows that words carry weight, and unnecessary words create noise.

This extends beyond tactics and into leadership culture.

Inexperienced leaders often believe authority must be constantly reinforced. They manage by talking: correcting, briefing, reminding, posturing. They confuse motion with progress. Experienced leaders understand that authority is reinforced by consistency, competence, and restraint. When they speak, people listen – because they don’t waste words.

The Goal Is Not to Have the Answer; It Is to Improve the Decision

The Dunning–Kruger Effect explains why this gap exists. Early in a career, a little knowledge creates dangerous confidence. You’ve learned enough to recognize patterns but not enough to understand exceptions. You mistake familiarity for mastery. Over time, exposure humbles you. Complexity reveals itself. You begin to see the edges of your understanding, and those edges are sharp.

So, you slow down.

• You start asking, what am I missing?
• You start listening for what isn’t being said.
• You stop trying to win arguments and start trying to solve problems.

This is especially critical in fast-moving VUCA environments. Ego-driven verbosity isn’t just annoying; it’s also corrosive. It shuts down subordinate input. It discourages dissent. It creates a culture where speaking up becomes risky, and silence becomes compliance.

Restraint Creates Room for Better Decisions

The inverse is also true: those who speak less tend to learn more. They absorb information laterally and vertically. They recognize that the team member out in the field or the junior analyst behind the screen may see something they don’t.

Silence creates space for others to contribute. And in complex systems, more perspectives mean better decisions. This doesn’t mean effective leaders are passive or indecisive. Quite the opposite.

As careers progress, many of us experience an uncomfortable transition: we realize we’re no longer the smartest person in every room and never were. That realization can either threaten the ego or mature it. The former leads to louder voices and tighter control. The latter leads to trust, delegation, and restraint.

The best leaders choose restraint.

Speaking Less Does Not Mean Leading Less

There’s also a personal dimension to this. With experience comes the understanding that not every thought needs to be shared, not every argument needs to be won, and not every mistake needs immediate correction. Wisdom teaches timing. It teaches that silence can de-escalate, protect relationships, and preserve credibility.

It teaches that sometimes the most professional response is to listen, nod, and wait.

In cultures that often reward assertiveness over accuracy and confidence over competence, this lesson is countercultural. In high-stakes professions, it’s essential. The more you know, the more you respect uncertainty. The more you respect uncertainty, the less you feel compelled to speak without purpose.

If you find yourself talking less as the years go by, if you feel more comfortable listening than lecturing, if you pause before offering an opinion, that’s not regression. That’s growth. That’s experience asserting itself.

The loudest voice in the room may command attention. The quietest one often commands respect.

And more often than not, the person who knows the most is the one who doesn’t feel the need to prove it.
