# Nonverbal Communication **Domain:** Communication / Perception / Social Signals **Doc Type:** Canonical concept node **Maturity:** Developed ## Definition Nonverbal communication is the transmission and interpretation of information through posture, expression, gaze, breathing, movement, timing, tone, and other signals beyond lexical content. ## Mechanism and Significance Observers integrate multiple cues, often rapidly and without conscious narration, to estimate emotion, confidence, attention, threat, affiliation, and intention. ## Evidence Boundary Nonverbal cues are probabilistic and context-dependent. They are not reliable lie detectors, and culture, disability, stress, and individual variation can change their meaning. ## Relationships [[wiki/Behavioral Signal|Behavioral Signal]] · [[wiki/Human Perception as Intelligence Object|Human Perception as Intelligence Object]] · [[wiki/Social Listening|Social Listening]] · [[wiki/Language|Language]] ## Related Articles and Collections - [[collections/Simple Reminders|Simple Reminders]] - [[articles/Analog Cognition and the Architecture of Continuity|Analog Cognition and the Architecture of Continuity]] - [[articles/Humans and AIs as Entangled Learning Systems|Humans and AIs as Entangled Learning Systems]] ## Simple Reminders, Quotations, and Thoughts > “Communication runs mostly beneath words. Posture, facial expression, eye contact, breathing, pace, fidgeting, trembling, skin moisture, and hesitation all broadcast information continuously. People read these signals like living lie detectors, often without knowing they are doing it.” > **— Bryant McGill**, *Becoming Too Expensive to Harm and Healing the Wounds Predators Notice - Livestream (Jan 2016)* [[reminders/Language/Communication Broadcasts Beneath Words by Bryant McGill|Communication Broadcasts Beneath Words by Bryant McGill]]
