On the science of the assessment itself: Validated assessments combine self-report items with rubric-scored responses, producing a percentile profile against a normed reference sample. The strongest instruments report internal consistency above . and test-retest reliability above . over multi-week intervals, with construct validity established against external behavioural and outcome measures rather than self-judgment alone. Construct definition: Couriers and Messengers, treated psychometrically, denotes a latent disposition inferred from converging behavioural indicators rather than a single observable. The instruments cited downstream measure the construct through rubric-scored item responses, with criterion validity established against external outcomes — supervisor ratings, longitudinal panel data, or audit-study callbacks — rather than self-perception alone. On limitations: most observational findings here cannot disentangle selection from treatment. Where audit-study designs were available, we preferred those — random assignment of identifiable signals onto otherwise identical applications removes the dominant confound. Sample-size, replication-status, and pre-registration metadata travel with each citation; readers should weigh effect size against base-rate noise rather than headline percentage.
