The Science of Wordless Communication
Estimates suggest that nonverbal cues make up roughly 60% to 93% of the meaning we derive from face-to-face interactions. While exact numbers are debated, nonverbal communication is broadly broken down into two main categories:
Your pitch, volume, pace, and the emphasis you place on certain words.
Facial expressions, eye contact, posture, and gestures.
The actual, literal words spoken.
The 55/38/7 Rule
This specific breakdown comes from UCLA psychologist Albert Mehrabian. It is important to note that these statistics apply specifically to how we communicate emotions and attitudes — especially when our words and body language contradict each other. For conveying pure factual data or complex ideas, spoken and written words remain paramount.
