The importance of measurement in psychology

Gunter Trendler (whose work on measurement in psychology we discussed last year) writes:

I’m aware that theoretical work on measurement is perceived by most psychologists as merely “philosophical” and therefore ignored.

Recently I’ve stumbled over a publication [Measuring Unobserved Variables in Educational Inequality Research: Mathematics and Language ‘Abilities’ in Early Childhood, by Alejandra Rodriguez] which investigates the problem of measuring “unobservable variables” empirically and may therefore attract more attention than purely theoretical argumentation.

I’ve also attached a paper from 2008 [Rationalization and Cognitive Dissonance: Do Choices Affect or Reflect Preferences?, by Keith Chen] that I’ve recently read and which, I believe, illustrates quite well what consequences ignoring nominal measurement may have.

I don’t have anything to add here. I glanced at the two linked articles but have not tried to read them in detail. I’m posting here because I think measurement in statistics is underrated so it’s good to be reminded of its importance.
