First impressions

Why people judge you before you speak, and what you can do about it

He appeared from the site office as I walked onto the car lot.

A swagger that could have been confidence. Could have been arrogance. Duffle coat, torn jeans, an old pair of Adidas. Cigarette in one hand, hot drink in a polystyrene cup in the other. A smile with a gold tooth.

A walking, talking stereotype.

My internal verdict arrived before he'd opened his mouth. Nope. Not today. Not from him.

I gave him the benefit of the doubt — stayed, looked around, had the conversation. The rest of the interaction did little to shift that first impression. I left without a car.

Here's the thing about first impressions. We make them in an instant. Less than a second. And despite what we tell ourselves about being open-minded, tolerant, and not particularly judgy — the research says otherwise. Our brains are quick, cautious, and remarkably accurate. We form an assessment before a single word is exchanged, and then, through confirmation bias, we spend the rest of the interaction collecting evidence to support it.

It is much easier to turn a good first impression into a bad one than to rescue a poor first impression once it's been made. That's not cynicism. That's just how the mechanism works.

First impressions are made on two dimensions. The first: are you here to help me or hurt me? Not just physically — socially, emotionally. Are you warm and agreeable? The second: are you competent? We read both of these from posture, clothing, facial expression, and general presence. We read them fast. We are, by most accounts, surprisingly good at it — even children are, which is either reassuring or a little unnerving, depending on your outlook.

None of this means we're always right. We often aren't. But being wrong doesn't stop the mechanism from firing. And once it has, the other person has to work hard, and we have to consciously choose to stay open, to change course.

The mechanism evolved to keep us safe — to flag potential danger before it became actual danger. The threats are mostly social now rather than physical, but the system hasn't updated itself accordingly. So we err on the side of caution. A slightly frosty handshake. A quiet decision not to take things further. An audience that checks out before the talk has properly started.

Which brings us to what we can actually do about it.

Posture matters more than most people realise. Standing tall — or sitting with your back straight and leaning very slightly forward — signals confidence and presence. A smile does a lot of heavy lifting too. Not a fixed, performed smile, but a natural one. It signals warmth. It signals that you're approachable. It tends to put people at ease in a way that very little else does.

Clothing sends a signal before you do. Dressing appropriately for the occasion matters — the car salesperson in a tuxedo would be baffling; the conference speaker in cycling shorts would be memorable for all the wrong reasons. But within context, dressing a little smarter tends to create a better initial impression.

It also does something interesting to the wearer — there's decent evidence that how we dress affects our own confidence and how we carry ourselves. Which in turn affects the impression we make. A virtuous circle, or a vicious one, depending on the wardrobe.

Eye contact carries a lot too. Too little and you can come across as uncertain or evasive. Too much and you cross a line into something more unsettling. Constant smiling has the same problem. Confident, natural, and human tends to be the target.

A speaker who shuffles onto a stage, shoulders hunched, avoiding eye contact with the audience — they're already communicating something, before they've said a word. The audience read it instantly. Do they want to be here? Are they sure about any of this? It's a hard hole to climb out of, even if everything that follows is excellent.

We can't control what people think. We never could. But we can influence it — significantly — and it starts in the first second.

The second car lot I went to was different. The salesperson came out with her shoulders back and a warm smile. Greeted me with a confident handshake. Listened throughout the conversation, wasn't pushy, and knew every detail about the car.

Sale in the bag.

And it turned out to be a great car.
