I revisit both with cleaner timing, newer data— kirabojackson.com/blog I use international test scores measured in 1999–2000 and then look at GDP-per-capita growth from 2001–2024. It covers 48 countries, with no overlap between the testing years and the growth years.

Classic result: countries with higher test scores grow faster; years of schooling add little once scores are included.

Concern: reverse causality—in the original evidence, some measured growth occurs before scores are observed.
