We often hear the phrase, “First impressions matter,” but how do we really gauge someone’s personality within just a few seconds of meeting them? It might sound like an impossible task, but according to psychology, subtle signs can reveal a lot about who someone is. Whether you’re meeting someone at a networking event, during an interview, or even in casual settings, being able to read these signs can give you insight into their personality in less than 10 seconds.

In this article, I’ll explore a few simple, psychology-backed tips to help you quickly assess someone’s personality based on their body language, tone of voice, and other subtle cues.

1. Posture: Confident or Guarded?

Body language is one of the first things we notice about someone. A confident posture—standing or sitting up straight with shoulders relaxed—signals self-assurance and openness. On the other hand, slouched or closed-off postures, like crossing arms, may indicate a more guarded or defensive personality. Pay attention to how someone positions themselves when they first enter a room or engage in a conversation.

2. Eye Contact: Trustworthy or Evasive?

Psychologists agree that eye contact is a key indicator of trustworthiness. Maintaining steady, yet natural, eye contact can suggest that someone is honest and comfortable with themselves. However, too little eye contact may signal discomfort, dishonesty, or a lack of confidence. Alternatively, excessive eye contact could indicate aggression or dominance.

3. Handshake: Assertive or Uncertain?

A handshake tells you a lot about a person’s personality within seconds. A firm, but not crushing, handshake is a hallmark of confidence and assertiveness. A limp or weak handshake can suggest uncertainty or lack of enthusiasm, while an overly aggressive grip might indicate a need to dominate or control the situation. The way someone greets you with their hands often mirrors how they approach life situations.

4. Facial Expressions: Friendly or Reserved?

Smiles and other facial expressions are windows to emotions. A genuine smile, known as the “Duchenne smile,” involves not only the mouth but also the eyes, showing true warmth and friendliness. A forced or half-hearted smile may indicate discomfort or a lack of sincerity. Someone who is relaxed and expressive with their facial gestures is more likely to be approachable and open-minded.

5. Tone of Voice: Calm or Anxious?

The tone and pace of someone’s voice often reveal their emotional state. A calm and steady voice suggests control, confidence, and ease in social situations. Rapid speech, a higher pitch, or fluctuating tone might indicate nervousness, insecurity, or anxiety. Pay attention not just to what someone says, but how they say it.

6. Choice of Words: Optimistic or Cynical?

Even within a few seconds, the words someone chooses can provide a glimpse into their mindset. Positive, forward-looking language often reflects an optimistic outlook, while overly critical or negative language can hint at cynicism or dissatisfaction. Pay close attention to their first few words and overall vibe during the conversation.

7. Personal Space: Respectful or Overbearing?

The way someone manages physical distance can tell you how comfortable they are with others. Someone who maintains an appropriate amount of personal space shows respect for boundaries and is likely socially aware. On the other hand, someone who invades personal space too soon might come off as overbearing or lacking in social cues.
