Why Is It Difficult to Rank the Highest IQ Scores?

[Campus reveiw]

Lists of the world's highest IQ scores are popular, but they can create a misleading impression that every number is directly comparable.

IQ assessments differ in their design, scoring systems, age norms, and reporting limits. Some widely circulated figures are historical scores, while others are estimates or claims without publicly available standardized test records.



A careful comparison should distinguish between documented testing, reported estimates, and achievements that can be independently established.

The Campus Review's article introduces notable figures associated with high IQ claims and explains why those numbers require context.
