On what makes the instrument behind the assessment trustworthy: 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. Scope and taxonomy: throughout this page Marketplace Seller refers to the modal cluster — occupational taxonomies (O*NET, ESCO, ISCO) draw boundaries differently, and a posting reading as Marketplace Seller in one taxonomy maps onto an adjacent code in another. Where downstream recommendations depend on taxonomy choice, we surface the distinction; otherwise we treat the cluster as a unit. 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 Marketplace Seller/Marketplace. Surrounding evidence we did not centre but considered: trial-design innovations such as masked-blind callback measurement; disability-disclosure framing experiments; longitudinal panels following candidates from application through retention; and natural experiments triggered by jurisdiction-level policy changes (ban-the-box, salary-history bans, AI-hiring disclosure mandates). Each refines but does not invalidate the picture this page sketches around Marketplace Seller. JobCannon's role here is narrow: to evaluate how much one specific skill moves pay and callbacks for Marketplace Seller using only validated instruments and primary-sourced evidence. The assessment linked above is the entry point, the pillar below is the wider context, and every claim across both is traceable to its source. No invented numbers, no aggregator paraphrase. On Marketplace specifically: that signal is one input among many on the result page, weighted against your own assessment scores rather than imposed top-down.
