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. Boundary conditions: regulators, employers, and researchers carve First-Line Supervisors of Mechanics, Installers, and Repairers along different boundaries. Regulatory definitions (EEOC, ICO, EU AI Act Annex III) are protective and broad; employer taxonomies are operational and narrow; academic constructs sit somewhere between. Findings reported under one boundary translate imperfectly onto another, and we annotate translations inline. A note on uncertainty: every effect size on this page sits inside a confidence interval, and most intervals are wider than the published headline implies. Treat percentage shifts as directional rather than precise. Where a finding originates in a single underpowered study, we annotate that explicitly; where it has been replicated, the annotation flags the replication count. Nothing on this page should be read as a forecast — historical effect sizes establish a prior, not a prediction, for First-Line Supervisors of Mechanics, Installers, and Repairers/Customer Success. Threads we deliberately excluded for length: courtroom outcomes versus regulator settlements; the pipeline view of bias accumulation across screening, interview, offer, and onboarding; cross-platform comparisons between LinkedIn, Indeed, and direct ATS submission funnels; and the role of structured-interview rubrics in attenuating downstream gaps. Each deserves its own citation chain. None overturns the headline finding for First-Line Supervisors of Mechanics, Installers, and Repairers, but each refines the conditions under which it generalises.
