Cohort Separability (Δ vs floor)
One brand emits the same eight-dimensional profile. Two cohorts weight those dimensions differently, so they perceive two different readings. A noise floor decides whether the gap between them is real — or just instrument noise you must not act on. This is an illustration — to measure a real brand from public evidence (with per-dimension noise floors and cohort resolution), use the Brand Spectrometer.

Cohort 1 · values-led — salience weights
Cohort 2 · experience-led — salience weights

Instrument resolution noise floor
Raise the floor and watch a “resolved” gap collapse to sub-resolution; pull the two cohorts’ weights apart to push the gap above the floor. The Spectrometer reports a difference only when it clears this floor.
About the named brands. The preset profiles are author-specified canonical values used throughout the corpus to keep worked examples consistent. They are illustrative, not measured — nobody was surveyed to produce them. More generally, the Brand Spectrometer reads publicly available discourse rather than a sampled respondent cohort, so a reading of an elite-luxury brand reports how it is described in the open record and is never the perception of verified luxury consumers.
What this shows. The same brand is perceived differently by different
cohorts — different salience weightings give different readings of one
perception cloud. There is no single audience-free reading. A measured
difference is meaningful only when it clears the noise floor; below it,
the difference is indistinguishable from instrument noise and must not
drive a decision — that is the difference between resolved and
sub-resolution. This mirrors the Brand Spectrometer's cohort-resolved
reflection with explicit noise floors.
What it does NOT claim. This is an illustration with a simplified scalar
projection and a single noise floor; the real instrument reports per-dimension resolution
and triangulates across public artifacts — measure a real brand with the
Brand Spectrometer.
For the theory, take the empirical path on the
researcher route or the
CMO route of the Guide.
From illustration to measurement
This explorable is a sketch of cohort-resolved reading. A real measurement weights each dimension by how a cohort actually attends, triangulates across public artifacts, and reports a noise floor per dimension — declaring a difference between cohorts only when the signal clears it. Below the floor, a gap is not a finding. That discipline is the Brand Spectrometer. For the theory of cohorts, perception clouds, and resolution, start from the empirical path or the CMO path on the Guide.
