INTRODUCTION

English translation pending.

CORE DEFINITION

A metric that quantifies cognitive ability through standardized tests, indicating a person's relative standing in abstract reasoning and problem solving. It offers a useful reference baseline, but the model insists on two limits: intelligence is multidimensional rather than a single number, and it is measurably plastic rather than fixed. The score is therefore a coarse map of one region, not the territory of a person's entire cognitive capacity or future potential.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Provides a coarse map: the score locates relative standing in tested reasoning skills - Bounds its validity: it measures part of ability, never the whole of a person - Guards against labeling: a score is treated as a reference point, not as a verdict

Anchor fast decisions

IQ compares an individual's test performance against a normalized distribution centered on 100, which yields a stable relative ranking for the specific abilities the test items sample. Because those abilities are only one slice of cognition, the number predicts some outcomes well while remaining entirely silent on many others that matter.
