How long does it typically take to form a first impression?

The formation of a first impression typically occurs within a matter of seconds. Research in psychology suggests that judgments about a person's trustworthiness, competence, and likability can be made very quickly—often in the blink of an eye. Factors such as facial expressions, body language, and initial interactions all contribute to these rapid assessments.

This quick evaluation is significant because first impressions can be difficult to alter once formed, impacting future interactions significantly. People rely on these swift judgments as a way to navigate social situations, meaning that the initial moments of an encounter are critical in shaping perceptions. Thus, the timeframe for forming these impressions is indeed very brief, aligning with the answer indicating that it typically takes only seconds.
