The Analytic Cart Before the Ontological Horse: A Response to Michell’s “The Mystery of Missing Psychometric Corpus ”

Mark J. Garrison

Short summary

This response argues that psychology's reliance on null-hypothesis significance testing (NHST) is linked to the "missing corpus" of critiques on psychometricians' assumption that psychological attributes have quantitative structure.

Key points

  • Psychology's reliance on NHST is connected to a lack of critiques on the assumption of quantitative structure in psychological attributes.
  • The distinction between "visible" (NHST) and "invisible" (measurement) critiques may obscure the role of NHST in driving measurement assumptions.
  • Political theory, not scientific evidence, played a role in the widespread adoption of psychometric methods.
  • The response challenges the a priori assumption that psychological attributes inherently sustain quantitative structure.

Abstract

This response to Michell’s article raises three main concerns. First, there is an important yet unexamined relationship between psychology’s reliance on inferential statistics (NHST) and the “missing corpus” of critiques of psychometricians’ a priori assumption that psychological attributes sustain quantitative structure. Second, framing the problem as one of “visible” (NHST) versus “invisible” (measurement) critiques may mask how commitment to NHST drove psychologists to assume measurement is taking place. Finally, Michell fails to account for the role political theory played in explaining the widespread adoption of psychometric methods, sans scientific evidence.
