More (not so) fun facts:
54% of American adults read below a 6th grade level.
21% read below a 5th grade level, which is considered functionally illiterate.
High immigration numbers don’t fully explain it either, as first gen immigrants only make up about 1/3 of those with low literacy.


A worse teaching method would produce many generations of uneducated people. And education is important because even with all these advancements made right now, if in the future the people fail to keep up with it, its going to be nothing.
I agree bad teaching practices can have knock-on effects (though I don’t think knowledge of phonetics was at real risk of dying out?). But so can bad health outcomes, learning environments, etc?
I think, especially in education, that effect sizes are difficult to judge. And I can’t find good data for reading ability over time. So I am very interested in what we are sure about/evidence is.
Something that I did find is this. Its US-only and doesn’t actually provide the numbers, but it tells you the general trend.
Ah, found one that does. 2022’s decline seems pretty significant, in both mentioned subjects.
Yeah that’s possible. Maybe in a few years, if the statistics stay the same, it’s a teaching failure.
