The Science of First Impressions

Research shows we form impressions of others in just milliseconds. Here's what science tells us about making those moments count.

The 7-Second Rule

Studies show people form a first impression within 7 seconds of meeting someone. In that brief window, we assess trustworthiness, competence, and likability based on facial expressions, body language, and tone of voice.

What Matters Most

According to research by Albert Mehrabian, communication is 55% body language, 38% tone of voice, and only 7% actual words. This means how you say something matters far more than what you say.

The Power of a Genuine Smile

A Duchenne smile—one that reaches your eyes—signals warmth and authenticity. People who smile genuinely are perceived as more attractive, trustworthy, and approachable.

Mirror Neurons at Work

Our brains contain mirror neurons that cause us to unconsciously mimic others. When someone leans in, we lean in. When they smile, we smile. This mirroring builds rapport naturally.

The Bottom Line

While first impressions happen fast, they're not set in stone. Be warm, be present, and be yourself. Science shows that authenticity is the most attractive quality of all.
