- Predictive: score now, outcome later.
- One that is itself reliable and relevant.
- Licensed batteries publish correlations with school and occupational criteria, with huge overlap.
- No.
- If everyone already passed a hard filter, correlations shrink.
- Reaction time and digit span are classic lab cousins.
Predictive versus concurrent?
Predictive: score now, outcome later. Concurrent: both now. Both are kinds of criterion evidence. Neither is automatic for a web toy. Pratica — non un QI clinico.
What is a good criterion?
One that is itself reliable and relevant. Predicting another noisy quiz is a weak story. Pratica — non un QI clinico.
Do IQ tests have criterion evidence?
Licensed batteries publish correlations with school and occupational criteria, with huge overlap. That literature is not this website’s games. Pratica — non un QI clinico.
Can I use this site to hire?
No. Adverse-impact law and professional standards need documented, job-related instruments. These lites are education. Pratica — non un QI clinico.
Restriction of range?
If everyone already passed a hard filter, correlations shrink. Forum samples mislead. Pratica — non un QI clinico.
What to play instead of forecasting income?
Reaction time and digit span are classic lab cousins. They still do not forecast your salary. Pratica — non un QI clinico.

What is construct validity?
Construct validity is the argument that a score reflects a named idea — working memory, not “being clever in general.” It is built from theory, patterns of correlations, and failed rival explanations. A 20-trial number-Stroop lite can feel like control. Feeling is not a validity coefficient. This site never reports a licensed IQ. Pratica — non un QI clinico.
What is construct validity? →What is content validity?
Content validity is whether the item set covers the skill or knowledge you claimed. A spelling test with only the letter Q is a coverage failure. Shape-span lite samples a tiny visuospatial sequence. It does not cover “all spatial intelligence.” Experts, blueprints and reviews build content arguments. A weekend hackathon does not. Pratica — non un QI clinico.
What is content validity? →What is a confidence interval?
A 95% confidence interval is a procedure: if you repeated the study under the same model, 95% of such intervals would cover the parameter. It is not the probability that this one interval magically contains the truth after you saw it. Licensed IQ manuals turn a standard error into a range around a scaled score. Digit-span lite does not. Treat any integer from this site as a toy count. Pratica — non un QI clinico.
What is a confidence interval? →What is item response theory?
Item response theory (IRT) models each item: harder items need more of the trait for a 50% chance of success; discriminating items separate nearby people. Computerized adaptive tests pick the next item from that model. Pattern-matrices lite is a fixed original set. It does not estimate a theta with published item parameters. It is not an IQ. Pratica — non un QI clinico.
What is item response theory? →What is a g-loading?
In a factor analysis of several tests, a general factor (g) can appear. A subtest’s loading says how much it shares that factor in that sample and battery. Matrices often load high; some speeded motor tasks load lower. A loading is not your worth. N-back lite is not a published g-loading table. This site does not output g. Pratica — non un QI clinico.
