Check the contradiction, drop the percentages
Tone and facial expression can dominate judgments of attitude when affective cues conflict—but the finding is not a universal 7–38–55 rule
Premise
Few communication claims are repeated more confidently or inaccurately than “93 percent of communication is nonverbal.” Albert Mehrabian’s two 1967 studies with Morton Wiener and Susan Ferris do not support that proposition. They examined a narrow problem: how observers infer liking or disliking when minimal verbal, vocal, and facial cues about attitude are inconsistent.
The responsible executive lesson is congruence, not arithmetic. When a leader’s words express approval while tone or facial behavior signals irritation, recipients may rely heavily on the nonverbal cues to judge attitude. That does not make language unimportant for facts, reasons, commitments, deadlines, or instructions.

Effects, Biases & Phenomena
Identifies a bounded pattern in judgment, behavior or communication and the conditions under which it appears. Naming the pattern makes a recurring difficulty recognizable; it does not make the pattern inevitable or supply a complete explanation.
