Explore the science of snap judgments with Eli and Miles. Learn how body language and nonverbal signals shape first impressions in just 100 milliseconds.

People form judgments about your competence and trustworthiness in as little as 100 milliseconds. By the time you’ve even processed that you’re looking at a human being, your brain has already filed them into a category.
Let’s chat about body language and being the most memorable person in the room.








The science of snap judgments reveals that humans form opinions on competence and trustworthiness in as little as 100 milliseconds. According to research by Princeton psychologists Janine Willis and Alexander Todorov, these impressions happen faster than we can speak. This rapid cognitive process, often called the snap judgment challenge, means your brain categorizes others almost instantly based on nonverbal signals before a single word is even exchanged.
Nonverbal signals act like invisible billboards that communicate whether you are an expert or someone hoping to go unnoticed. If your body language screams uncertainty, your audience may check out mentally before you begin speaking. Because these signals are processed so quickly, projecting confidence through your physical presence is essential to being seen as a leader and avoiding the difficult task of reversing a negative initial impression later on.
Incongruence occurs when a person's spoken words do not match their physical body language. In these situations, listeners almost always believe the nonverbal cues over the verbal message. This mismatch can lead to a lack of trust, as the brain prioritizes the signals it receives from body language. Understanding the science of snap judgments helps individuals ensure their physical presence aligns with their message to remain memorable and trustworthy.
