We've all heard the cliché: "You never get a second chance to make a first impression." But how much truth is there in that statement? And if first impressions truly matter so much, what's actually happening in our brains during those crucial first moments?

Science confirms that first impressions are incredibly significant. Researchers have found that we form lasting judgments about someone's trustworthiness, intelligence, and competence within mere seconds—often as quickly as 7 to 10 seconds upon meeting them. But how is this possible? Why do our brains form these rapid evaluations, and how accurate can they really be?

Neuroscience gives us valuable insights. When you meet someone for the first time, your brain quickly gathers a wealth of information—facial expressions, body language, clothing, tone of voice, eye contact, and even subtle cues like scent. Your brain integrates these inputs rapidly, creating an immediate, intuitive evaluation. This process occurs primarily in the amygdala, an area responsible for processing emotions, threats, and social cues. Within milliseconds, your brain instinctively determines whether this new person is friend or foe, trustworthy or suspicious.
