Not even just a category error -- this is blatant malpractice to have this as a headline! The article is talking about reading scores, and this is especially pernicious given the fact that the last couple of years has not been "typical" by any measure; I seem to recall a global pandemic that might have had some influence.

The numbers here are so overdetermined that it will never be possible to do a causal analysis, and jumping to "screen time" is almost outlandishly unjustified.
