Is g “intelligence itself”?
It is a statistical summary of shared variance. Philosophers and psychologists still argue what it names in the world. अभ्यास — नैदानिक IQ नहीं।
Do all good tests load 1.0?
No. Specific factors and error exist. A low loading can still be useful for a narrow decision. अभ्यास — नैदानिक IQ नहीं।
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. अभ्यास — नैदानिक IQ नहीं।
Verbal versus spatial loadings?
Both can load g and still look different. Profiles are not two species of human. अभ्यास — नैदानिक IQ नहीं।
Is a high-g job a high-g person?
Occupations differ in average scores with huge overlap. Do not hire from a lite game. अभ्यास — नैदानिक IQ नहीं।
What to try?
Pattern matrices lite and verbal analogies lite sit on two classic families. Still not a g report. अभ्यास — नैदानिक IQ नहीं।

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. अभ्यास — नैदानिक IQ नहीं।
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. अभ्यास — नैदानिक IQ नहीं।
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. अभ्यास — नैदानिक IQ नहीं।
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. अभ्यास — नैदानिक IQ नहीं।
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. अभ्यास — नैदानिक IQ नहीं।
