Re: Really ?
From a Forbes article including the quote "":
"Adults who scored below Level 3 for literacy on the PIAAC were defined as at least partially illiterate. Adults below or at Level 1 may struggle to understand texts beyond filling out basic forms, and they find it difficult to make inferences from written material. Adults at Level 2 can read well enough to evaluate product reviews and perform other tasks requiring comparisons and simple inferences, but they’re unlikely to correctly evaluate the reliability of texts or draw sophisticated inferences. Adults at Level 3 and above were considered fully literate. They’re able to evaluate sources, as well as infer sophisticated meaning and complex ideas from written sources."
That level 2 - "well enough to evaluate product reviews and perform other tasks requiring comparisons and simple inferences, but they’re unlikely to correctly evaluate the reliability of texts or draw sophisticated inferences" - seems to me to a very broad definition of partially illiterate. Maybe that is unavoidable, because "literacy" is not a binary but a continuum.
I recall the back in the day of print media, Time magazine, one of the US' more popular magazines, was very strict about writing all articles with a vocabulary that could be understood by a sixth grader - in the context of the study in question, a borderline illiterate.
However, I do think that there has been some dumbing down - Time is out and Twitter, Facebook, You Tube, and Tik Tok are in.
