From Nuclear Physics to Psychometrics: A Journey Through Measurement
The first doctorate was in Experimental Nuclear Physics. The second was in Statistical Psychometric Methods, earned summa cum laude at Rutgers University. The arc between them is not a detour. It is the foundation.
Nuclear physics trained an exact relationship to measurement, the kind of discipline that knows the difference between what you can claim from data and what you cannot, that takes systematic error seriously, that treats a well-designed experiment as a form of philosophical argument. A paper published in Physical Review Letters (one of the most selective physics journals in the world) marked the end of that chapter.
Psychometrics extended that rigor into the human domain. Latent variable modeling. Item Response Theory. Factor analysis. Bayesian methods. The dissertation (on Stochastic Approximation EM for Exploratory Item Factor Analysis, published in Statistics in Medicine) applied Monte Carlo methods to the problem of measuring things that cannot be directly observed. Cognition. Personality. Intelligence.
The bridge between these two fields is measurement theory: the discipline of determining what can be validly inferred from data, and what cannot. That discipline is the backbone of the Mindwright approach to epistemic fitness. You cannot think clearly about AI without it.
