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?

Historical evidence through 2026-08-27 about the narrow experiments, cross-study proposal, later qualification, direct rebuttal, and propagation of 7-38-55. This evidence file does not establish a universal law of communication.

encyclopedia finding

documented narrow historical proposal with explicit experiment and edition boundaries

What to do with that: Use 7-38-55 only as the history of a narrow feelings-and-attitudes proposal assembled across two linked experiments.

The original participant roots, cross-study proposal, later qualification, and follow-up evidence are different objects.

Lineage accounting

The units count different things

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

Warrant boundary: The fixed three-number formula was proposed across studies; neither original experiment tested verbal, vocal, and facial channels together.

A final comment is required to integrate the implications of the findings of the present study with the findings of the Mehrabian and Wiener study (1967) ... It is suggested that the combined effect of simultaneous verbal, vocal, and facial attitude communications is a weighted sum of their independent effects ... with the coefficients of .07, .38, and .55, respectively

A final comment is required to integrate the implications of the findings of the present study with the findings of the Mehrabian and Wiener study (1967) ... It is suggested that the combined effect of simultaneous verbal, vocal, and facial attitude communications is a weighted sum of their independent effects ... with the coefficients of .07, .38, and .55, respectively

Five-line lexicon

The units are different on purpose

Participant-data root
One distinct reported participant collection after shared papers and programs are collapsed.
Cross-study proposal
An integration suggested across studies, not a result directly tested in one experiment.
Propagation object
A document showing that a claim circulated; it supplies no truth credit.
Direct rebuttal
A later all-channel test whose reported equations challenge a fixed universal rule.
Unresolved derivation
A coefficient origin the reviewed primary editions do not disclose.
