There is no such thing as "average IQ by country". It's baffling to me that so many people believe there would be, because so few of us have ever been asked to take a proctored IQ test in any setting, let alone as part of a nationwide survey. These things aren't real; they generally source Richard Lynn's fraudulent numbered from "IQ And The Wealth Of Nations" and unproctored online IQ tests with, like, dropdowns where you can claim to be from specific countries.

If this told me anything it's that most of the world falls within 5 point difference, guess we're doing good

USA above average? That cannot be true

So I am supposed to believe that from 2024 to 2025... Australia IQ increased by two points... or that China dropped one point from 2024 to 2025? Or Iran dropped two points in IQ between 2024 and 2025?

Or is this a case of data bullshit?
