  • I’m saying that just because something is specifically intended for something doesn’t imply that it has a larger effect than other things which have broad effects.

    So no, the fact that homeopathy is psudoscience is irrelevant for my example (and the argument as you phrased it above). I read you, effectively, as saying:

    because teaching is intended to influence literacy, and poverty reduction influences many things, teaching has a bigger effect


  • 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.




  • I agree that we have made recent changes that were bad. But we’ve also expanded access to free lunches in some places, decreased some extreme poverty metrics, have expanded AuDD diagnosis and treatment, raised the minimum wage in a handful of large metro areas, etc.

    Is it obvious that a worse teaching method (and the many other bits of bad policy) does more damage than the improvements? This isn’t clear to me.


  • This seems to be hard to tell from the data. While the others are right that there have been recent downward movement, the country is old and we don’t have data going back very far.

    basic literacy has almost certainly increased (meaning one can write a sentence about onesself, and read it). The large majority of Americans meet this bar (and the rest are children or quite old/sick), while only ~80% met this bar 100 years ago.

    But it seems we haven’t kept data on reading level for very long. The wikipedia page is pretty good afaict. I suspect what actually matters for democracy and such is the literacy rate of voters, though I haven’t seen great data on it. We know a large share of folks don’t vote, I would guess this correlates very strongly with literacy.

    Also, there’s a relevant confounder here (which the wikipedia page highlights): one can be american and not speak english, but still be literate in their childhood language.
