- It is a statistical summary of shared variance.
- No.
- You can get better at that item type.
- Both can load g and still look different.
- Occupations differ in average scores with huge overlap.
- Pattern matrices lite and verbal analogies lite sit on two classic families.
Is g “intelligence itself”?
It is a statistical summary of shared variance. Philosophers and psychologists still argue what it names in the world. Übung, kein klinischer IQ.
Do all good tests load 1.0?
No. Specific factors and error exist. A low loading can still be useful for a narrow decision. Übung, kein klinischer IQ.
Can I raise my g-loading by grinding matrices?
You can get better at that item type. Changing a factor loading in a published battery is not what a web streak does. Übung, kein klinischer IQ.
Verbal versus spatial loadings?
Both can load g and still look different. Profiles are not two species of human. Übung, kein klinischer IQ.
Is a high-g job a high-g person?
Occupations differ in average scores with huge overlap. Do not hire from a lite game. Übung, kein klinischer IQ.
What to try?
Pattern matrices lite and verbal analogies lite sit on two classic families. Still not a g report. Übung, kein klinischer IQ.
❓ Häufig gestellte Fragen
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. Übung, kein klinischer IQ.
What is construct validity? →What is criterion validity?
Criterion validity asks whether a score lines up with something you care about that is not the test itself — a later grade, a supervisor rating, or a Wechsler index. Concurrent means measured at the same time; predictive means later. A visual 2-back lite has no published criterion table. It is not an employment screen and not an IQ. Übung, kein klinischer IQ.
What is criterion 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. Übung, kein klinischer IQ.
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. Übung, kein klinischer IQ.
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. Übung, kein klinischer IQ.
