# Case 004 — What the Mehrabian 7-38-55 weighting did and did not show

What did the 7-38-55 weighting represent in the examined primary editions, how was it derived, and what supports or undercuts its circulation as a general rule of communication?

**Skeptical finding:** withhold universal rule and withhold recovered-origin claim for the seven-percent coefficient

**Practical reading:** Do not teach that 93 percent of communication is nonverbal: no reviewed three-channel experiment established that universal rule.

The .07 origin remains unresolved, and direct all-channel evidence produced message-specific equations.

## Evidence accounting

- [2 original 1967 experiments](#original-experiments): Two different participant groups tested two different channel pairings
- [5 participant-data roots](#participant-data-roots): Original, direct-rebuttal, and related studies remain separate
- [3 zero-credit propagation objects](#zero-credit-propagation): Circulation documents popularity, not scientific truth
- [1 unresolved coefficient derivation](#unresolved-derivations): Reverse engineering does not recover the source of the verbal weight

**Dependence warning:** The two 1967 participant groups are distinct, but their papers share authorship, grants, materials, methods, scales, speakers, citation, and the later cross-study derivation.

## What the selected record says

### Support

The circulated claim that 93 percent of communication is nonverbal is not a result established by the two 1967 experiments.
