>IQ is not a genuine measurement of cognitive capacity.

False. IQ tests measure cognitive capacity well.

They are among the most accurate (in technical terms, reliable and valid) of all psychological tests and assessments.

Higher IQ people tend to be better at all tasks that involve thinking, regardless of the form and content of the task.

In other words, the general intelligence factor measured by IQ tests (also called g) is infinitely general.

The more complex a task is, the more predictive g is for performance on that task. In other words, more complex tasks are more g loaded.

That aligns well with the general public's use of the term, "intelligence."

g is more strongly related than any other measurable human trait to many important educational, occupational, economic, and social outcomes.
