- 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. 練習であり臨床IQではない。
What is a good criterion?
One that is itself reliable and relevant. Predicting another noisy quiz is a weak story. 練習であり臨床IQではない。
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. 練習であり臨床IQではない。
Can I use this site to hire?
No. Adverse-impact law and professional standards need documented, job-related instruments. These lites are education. 練習であり臨床IQではない。
Restriction of range?
If everyone already passed a hard filter, correlations shrink. Forum samples mislead. 練習であり臨床IQではない。
What to play instead of forecasting income?
Reaction time and digit span are classic lab cousins. They still do not forecast your salary. 練習であり臨床IQではない。

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. 練習であり臨床IQではない。
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. 練習であり臨床IQではない。
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. 練習であり臨床IQではない。
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. 練習であり臨床IQではない。
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. 練習であり臨床IQではない。
