Good information at the link - thanks for the post. I need to chase down some of the referenced support data, particularly that OECD report. Just interpreting from my experience & education on adult education, I think those literacy levels have some parallels to a classic education psychology approach called Bloom’s Taxonomy.

My suspicious eye is attracted to the words "Percent of subpopulation."

I think there is mischief represented there.
