Re:Is there a general factor of intelligence? by ZeroGravitas on Friday March 25, 2022 @01:01PM (#30804595)
Something I've tried to look up and never got anywhere with is why IQ is normalised by age?

The article mentioned testing physical strength of 20 and 80 year olds that reminded me of this.

Which age does best on raw test scores? Seems surprisingly hard to Google this info but I assume it's out there?

edit: a renewed effort to google suggests the things IQ tests test peak in late teens.
