The following table provides access to a series of large language model interrogations of health technology assessment (HTA) teaching and research knowledge bases across 72 Colleges and Schools of Pharmacy in the United States. Each interrogation applies a fixed set of canonical statements derived from the axioms of representational measurement to assess whether the conditions required for quantitative claims are recognized and applied.
The results are conclusive. Without exception, these interrogations demonstrate a consistent and pervasive pattern of measurement inversion. Across all programs, the foundational requirements for measurement with unidimensional attributes, admissible ratio scales, the distinction between manifest and latent attributes, and the necessity for measurement to precede arithmetic are not embedded in the analytical frameworks that are taught and applied. At the same time, numerical constructions and composite measures are routinely treated as if they were valid representations of therapy impact.
This is not a matter of variation between institutions. It is a shared and structurally consistent pattern across the entire set of PharmD and associated graduate programs. The implication is direct: the current HTA analytical framework, as taught to professional and postgraduate students, does not support quantitative methods as required by the agreed axioms of representational measurement which were made clear in 1971. Numerical outputs are generated in HTA, but the conditions required for their interpretation as measures are not satisfied. The result is assessments with reference case models that are just numerical storytelling. The details of this are set out in a recent paper HEALTH TECHNOLOGY ASSESSMENT – A 40-YEAR LEGACY OF MEASUREMENT INVERSION FOR MANIFEST AND LATENT ATTRIBUTE CLAIMS.
The message from these findings is clear. The issue is not one of incremental improvement or refinement. A framework that does not meet the axioms of representational measurement cannot be adjusted to do so. The imperative is therefore a transition to a measurement-based approach, in which claims are anchored in defined attributes and evaluated using scales that satisfy the requirements for measurement: linear ratio scales for manifest attributes and logit-based ratio scales for latent attributes.
There is no alternative. Without this transition, HTA teaching and practice will continue to rely on numerical constructions that cannot support quantitative claims of therapy impact; perpetuating four decades of measurement failure in HTA.
Viewed in this way, the assessments are best understood as a starting point for constructive engagement and a transition to the axioms of true measurement. They provide a shared reference for faculty, researchers, and students to explore how existing approaches can be strengthened, and how emerging measurement-based frameworks may be incorporated incrementally within current curricula and evaluation processes.
What is required is a transition to a measurement-based framework that recognizes:
Measurement must precede arithmetic; claims must be grounded in defined measurement properties before numerical operations are applied
All value claims are claims about attributes that must be clearly specified and unidimensional
The type of attribute determines the form of measurement: manifest attributes requirelinear ratio measures; latent attributes require Rasch logit ratio measures
Scale properties define permissible operations; multiplication and ratio comparisons require ratio-scaled measures with a true zero
Composite and multiattribute constructions must be treated with care; claims should be based on single, well-defined attributes
Protocols are required to support evaluation; claims must be specified in terms of population, timeframe, measurement, and analysis
Claims must be open to empirical evaluation and potential falsification
The role of assessment is to determine whether claims meet these conditions, not simply to compare numerical outputs
Taken together, these principles provide a structured basis for strengthening HTA teaching and practice, and for supporting the development of claims that are credible, evaluable, and replicable.
