Is the IQ test really the best way to assess someone's intelligence?

 The best way to analyze a person's intelligence is to conduct a comprehensive psychological, cognitive, and even "cultural" assessment. IQ tests, however well-designed, are like "quick tests" that provide a relatively accurate idea of ​​our quantitative intelligence levels but reveal nothing about qualitative aspects—specifically creative, rational, and emotional capabilities. They are particularly useful for comparing large groups of people but do not seem exceptionally comprehensive at the individual level. It is the difference between, for example, observing Earth from a spaceship and gradually getting closer to it. Nevertheless, such tests remain important within a comprehensive analysis. Yet, again, they offer only a preliminary idea of ​​our capacities and skills (developed abilities)—a starting point rather than a final conclusion.

There also seems to be a tendency to associate any mathematical application with objectivity, while assuming the opposite when such methods are not used. Yet, I see little difference between objectively perceiving that a person is more intelligent in certain domains and administering tests to derive numbers representing that person's performance.

The most common interpretations of cognitive test results attempt to flatten a "mountain range" of individual and comparative variations into a plain. It is as if—because Person X has an IQ of 140 and Person Y has an IQ of 110—Person X is absolutely more intelligent than Person Y. That is precisely the point! As long as qualitative aspects remain unevaluated, one cannot claim anything of the sort. Even if—or when—those aspects are assessed, and a significant performance gap is found across all domains, every "mountain" has its "lows" and "highs." Our intellectual performance cannot be reduced to a single test; we are constantly required to understand and adapt, navigating situations ranging from the trivial to the highly challenging.

Analyzing intelligence solely through quantitative aspects and regarding that assessment as complete is akin to... ...than to perform a "check-up" on half the systems that make up our bodies and define it as a complete check-up.
