Yeah, this is Horvath again. My biggest complaint about his research is that it is almost entirely correlation. Horvath specifically blames “edtech” as the reason for the decline, completely glossing over what this article seems to claim as the cause, short form videos and content. Not to mention all of the other societal shifts during this time, like the effects of No Child Left behind on schools.

Anytime I see this guy trotted out and his claims said as fact I just can’t take the article seriously.
