What cognitive aptitude actually measures
Cognitive aptitude is the speed and accuracy with which a person learns and applies new information. It's not what they already know — it's how quickly they get to competence on things they haven't seen before. Decades of meta-analytic evidence (Schmidt & Hunter and successors) place general cognitive ability among the strongest single predictors of job performance across role families, especially for complex work.
Why aptitude alone doesn't hire people
Aptitude predicts speed to competence, not motivation to apply it.
High-aptitude, low-interest hires learn fast then disengage — a distinct attrition pattern.
Aptitude has no floor for interpersonal or ethical judgment; a smart bad hire is worse than a mediocre good one.
Adverse-impact risk means aptitude testing needs guardrails: job-relevance justification, band scoring, and combination with other predictors.

How EQIQs uses cognitive aptitude
Cognitive aptitude is one of the 21 frameworks EQIQs blends. It's paired with RIASEC and values so the read answers both 'can this person do the job?' and 'will they want to?' — the combination is a stronger predictor than either alone. EQIQs reports aptitude in bands (not raw IQ points) and never as a stand-alone hire/no-hire signal, in line with EEOC guidance.
The interpretation rule EQIQs enforces
EQIQs never surfaces a raw IQ number to decision-makers. Aptitude is expressed as a role-relevant band with a plain-English read of what it predicts on this job and what it doesn't. That prevents the two most common misuses: over-weighting a single number, and interpreting aptitude as a proxy for character or fit.
