A THE LIBRARY medley moves from ideas about human nature and self-awareness to examples of body language, then cites the familiar 7–38–55 formula. The useful lesson is to notice context and question first impressions. A gesture is not a reliable way to read someone’s mind.
What the video says about observing people
The speaker discusses listening, checking personal assumptions and paying attention to changes in someone’s usual behaviour. These are prompts for curiosity, not a personality test. A person may touch their neck, cross their arms or move their feet for many reasons, including habit, discomfort, temperature or the situation.
Do not treat one movement as proof of fear, dishonesty or a hidden intention. The examples in the video are the speaker’s interpretations; the cited material does not validate each gesture as a dependable diagnostic cue.
What the 7–38–55 formula means
The formula is often repeated as “only 7% of communication is words.” That is not what Albert Mehrabian’s work established. His explanation says the percentages came from experiments about communicating feelings and attitudes—especially liking or disliking—when words and nonverbal cues were inconsistent. The 7% referred to verbal liking, 38% to vocal liking and 55% to facial liking in that narrow context.
Mehrabian’s own explanation of Silent Messages says the equations do not apply when someone is not talking about feelings or attitudes. The original studies—Inference of attitudes from nonverbal communication in two channels and Decoding of inconsistent communications—used specific laboratory conditions. They did not measure what percentage of every conversation, presentation or written message comes from body language.
Use body language as context, not a verdict
- Look for context and patterns over time instead of assigning meaning to one gesture.
- Remember that the same behaviour can have different causes for different people.
- When the message matters, ask a neutral question and listen to the person’s answer.
- Do not use body-language shortcuts to diagnose, accuse or claim that someone is lying.
The medley can encourage attentiveness and empathy, but the 7–38–55 formula is not a universal communication rule and body language is not a lie detector.
