3.2 Psychometrics

Psychometrics, a quantitative subfield of psychology and education science, encom-
passes the theory and technique of measuring unobservable, latent, abstract concepts
called constructs, like personality, intelligence, or moral ideology. Psychometrics is
commonly used in the development and validation of standardized educational tests
(e.g., the SAT, LSAT, GRE) [62], medical and psychological clinical assessments [63],
and large-scale public opinion polls [64].

Psychometric tests (e.g., survey instruments, measures, multi-item scales) are tools
for quantifying latent psychological constructs like personality. Psychometric tests
enable statistical modeling of the true levels of unobservable target constructs by rely-
ing on multiple indirect, yet observable, measurements across a sample of individuals
drawn from a wider population.
