What are first impressions typically based on?

First impressions are primarily based on opinions formed after the first meeting with a person. These impressions are often influenced by various non-verbal cues such as body language, facial expressions, tone of voice, and overall demeanor during that initial encounter. Over the years, psychological studies have shown that individuals quickly assess others, often within seconds, leading to immediate judgments about personality traits, trustworthiness, and likability. This is why the initial moments of interaction hold significant weight in shaping the perception that follows.

In contrast, detailed interviews, written evaluations, or social media profiles typically require longer interactions or more extensive information that may not be available in a brief initial meeting. While these can provide additional insights into a person's character or professionalism, they do not play a role in the formation of the very first impression one has of another individual.
