The Logit Working Papers present a structured interrogation of contemporary health technology
assessment (HTA) knowledge bases, focusing on a single question: do current HTA practices
meet the axioms required for measurement? Using large language models, each paper examines a
defined corpus of published literature, guidelines, and institutional frameworks for agencies,
journals, and academic programs. A fixed 24-item diagnostic instrument, derived from the
principles of representational measurement, is applied to determine whether the conditions
required for quantitative claims are recognized or violated. The results are expressed as
categorical endorsement probabilities and normalized logits, providing a consistent and
reproducible profile of how measurement is represented in practice.
The findings are unambiguous. Across interrogations, a consistent pattern of measurement
inversion is observed: numerical constructions are treated as measures without demonstration
that the underlying attributes and scales satisfy the conditions required for measurement. This is
not a matter of methodological variation, but a structural feature of HTA. Where measurement is
not established, arithmetic operations lack interpretive meaning, and claims cannot be expressed
in a form that supports empirical falsification. The consequence is that current HTA frameworks
cannot support the evolution of objective knowledge in the assessment of therapy impact.
The purpose of the Logit Working Papers is therefore not descriptive, but corrective. By
establishing a reproducible baseline of measurement failure, the series makes clear that there is
no intermediate position; this is shown conclusively in a recent paper:
Either HTA aligns with the axioms of representational measurement, recognizing the constraint to admissible ratio scales for manifest and latent attributes or it continues to rely on numerical constructions that cannot support quantitative claims only numerical storytelling. The transition is not optional. It is
the necessary condition for restoring HTA as a framework capable of generating evaluable,
testable, and scientifically credible claims.
