Speaking as Sense-Making: Why Public Speaking Shapes Leadership

Speaking as Sense-Making

Watch a speaker walk onto a stage and you can usually tell, within a few seconds, whether the room is with them. Not from the slides, and not from the polish. From something harder to name – whether the person seems to mean what they are about to say.

And yet the first few seconds decide far less than we think. What decides the rest is the talk itself: whether it helps the room see something it couldn't see before.

That is the part of public speaking we tend to undersell. We treat it as a performance skill, a thing you switch on for the conference or the client pitch. It is closer to the centre of the work than that.

Being good at the work is not the same as being good at explaining it, and as careers unfold, the explaining becomes unavoidable. Leaders speak. Managers speak. So do the people who influence without ever holding the title. Public speaking is not a career accessory. It is how ideas move.

Why public speaking decides whose ideas move

In organisations, decisions rarely follow the best data. They follow the clearest story.

Numbers persuade spreadsheets; stories persuade people. Public speaking is how alignment forms, how strategy becomes shared, how intent becomes collective creative action.

The person who can stand up and name what matters shapes outcomes that the more technically gifted, quieter colleague never gets near – not because they know more, but because they can carry what they know into the room.

Public speaking is interpretation, not performance

Here is the reframe that changes how the whole thing feels. A talk is not a performance in the theatrical or stage sense. It is interpretation – helping others see what you see. Sense-making, done in public.

That takes the weight off being impressive and puts it back where it belongs: on being understood. It also explains why so many capable people struggle on a stage.

They prepare to present information when the actual task is to make meaning – to translate complexity and ideas into something a room can hold and act on.

Bring the facts to life

Many talks rest on facts – data, market share, evidence, history, science, research. But facts say very little on their own, and they don't persuade. They need context, and they need a person to bring them to life and set them in the minds of others, next to what those people already believe.

"Stories go where facts cannot" is one of my principles of effective communication, and it holds on every stage I have stood on. Listing facts is easy. Making them mean something is the skill – being clear, giving context, carrying credibility, and staying human while you do it. That humanising is what a speaker adds that a slide never can.

Don't imitate other speakers

Watch as many talks as you can and study what works – then resist the pull to copy it. Borrowed voices are obvious – they ring hollow. When a speaker takes on someone else's cadence, gestures or persona, the audience feels the seam.

Presence isn't a technique; it's coherence between what you think, what you believe, how you appear and how you deliver. Take the elements that genuinely fit and weave them into something that is yours.

Use the words you would naturally use. Bring your own experience. Improve constantly – but don't put on someone else's mask, because it slips, usually mid-talk, and the room watches it go. It is precisely your own style that lets you persuade. People are moved by people.

Practice makes permanent, not perfect

A lot of would-be speakers never take the stage because they are waiting to be ready. Perfection is a form of procrastination. Perfection doesn't exist, it's subjective, and there is always something you could have done better – twenty years in, I still leave the stage knowing that. Aiming for flawless is how good talks never get given.

Practice does something more useful than making a talk perfect. It makes it permanent.

Rehearse until you can't forget the shape of it, until the basics are fluid and you're free to be present in the room rather than clinging to your notes. A talk is never finished. It is only shared.

This is most of what I focus on in Zero to Keynote – the refining of an idea, the shaping, the preparation, the structure, the rehearsal – because that is what lets your own style come through on the day. I say that 90% of your success in a talk is done before you hit the stage.

Let your enthusiasm show

Somewhere in corporate life, neutrality got mistaken for professionalism, and enthusiasm became suspect.

But emotion is often the only honest signal that a subject is worth attention. You don't need to bound around a stage to show it. I've seen enthusiasm arrive quietly, in stillness, and I've seen it arrive in wild gestures – both worked, because both were real.

If you know your topic and care about it, it comes through on its own. Don't water it down. If you're not visibly interested in what you're saying, there is little reason for the audience to be.

First impressions matter – your talk matters more

The science on first impressions is strong. An audience decides quickly, weighing two things: is this person friendly, and are they competent. Clothes, posture and movement set that first read, so it's worth looking the part for the room you're in and carrying yourself well.

But the first impression is only the opening. I've watched speakers walk on hunched and nervous, then deliver something that grabbed the room and warmed it.

I've watched others stride on with confidence and lose everyone by the ten-minute mark with a muddled argument. First impressions matter; the talk matters more.

Bring the facts to life, tell a story, deliver with clarity and your own energy, and the room revises its first read of you.

Speak with purpose

Every talk carries intent – to inform, to persuade, to inspire, to unsettle, to entertain. Sometimes multiple. Clarity of purpose is what produces clarity of speech.

Work out what the talk is for before you build it, and shape everything around that one aim. Without it, even fluent delivery becomes noise, and a well-dressed speaker with good slides can still leave a room with nothing to do.

Public speaking isn't about charisma. It's about coherence – thought, belief and delivery pointing the same way – and about making meaning visible, so that others can see, and therefore act.

Which is why, for anyone leading, it was never really optional. Public speaking is the medium through which leadership happens.
