Strength & Valence

Why two sliders, not one. A single “love-to-hate” dial would force you to trade strength for direction — turning up the dislike by turning down the intensity. That is the error this page corrects. Strength and valence are orthogonal: hold the marker at the top and slide it sideways and the strength never changes — only the sign flips, one step from devotion to the strong feeling people call hate. Down low, weak-positive and weak-negative are still different perceptions, not one undifferentiated blob. A strongly disliked brand is a strong perception, not a weak one — the common reflex that “strong” means “liked” is exactly the confusion the two axes dissolve. A cohort's spread across the valence axis (polarization) is brand conviction, not “attitude.” This is an illustration of the property; its measured realization is the Brand Spectrometer, which reads strength and valence per cohort from real public artifacts — carrying valence as a noise-floored measurement (a lean is shown only when it clears the floor) and the cross-cohort valence spread as the brand-conviction signal.

Where the measurement stops. Valence is the last thing the instrument honestly reads. There is a chain — perception (what a cohort registers) leads to valence (how it leans) leads to desire (how much they want the brand) leads to demand (whether they act) — and each downstream step adds confounds and loses text-measurability. The Brand Spectrometer measures the first two and stops. Desire and demand are downstream constructs that consume this read: perception and valence are inputs to whatever demand model a decision-maker builds on top of them, and the instrument deliberately does not claim to measure them. The restraint is the credibility — the same discipline as abstaining below the noise floor.
