The Relevance of the Logic of Measurement to Psychometrics

December 11, 2018 - 4:00pm

Walter Library, Room 101

The logic of measurement exposes the soft underbelly of psychometrics. Psychometric theories entail that constructs are continuous quantitative attributes and because the logic of measurement describes the structure of such attributes, it specifies the structure of constructs. Furthermore, since non-quantitative attributes exist, there is no a priori necessity for attributes to be quantitative and, so, the issue of whether any given attribute is quantitative is determinable only a posteriori; there is no hard evidence that constructs possess quantitative structure; therefore, there is no hard evidence that constructs are measurable. Thus, the logic of measurement shows any claim to measure constructs to be unwarranted.
