429.- Lenguaje corporal, dinero y relaciones, qué revela tu cuerpo | Bárbara Tijerina

The conversation centers on how nonverbal signals determine whether others trust, follow, or reject us, often before any words are exchanged. Bárbara Tijerina explains that words carry only 7 percent of communication weight, while tone accounts for 38 percent and body signals for 55 percent.

Open posture, steady eye contact, and a measured pace signal leadership and honesty before speech begins. Closed posture or rapid, jerky movements trigger the opposite reading. The insula interprets posture as information about internal state, so a slumped position literally feeds the brain signals of low value or sadness, which others then perceive.
