Not explicitly arguing against the thesis of the website, but showing trend lines which allegedly started in 2007 with data that starts in 2006 is... Not convincing.

Agree. Might as well start with internet adoption, but the phone allows us to carry that weight with us all day. To be sure it started a bit sooner.

Exactly, I've been net-addicted since .. uh, BBS culture in the late 80s, and I almost never use my smartphone but have my laptop or computer screen in front of me most of the day. I don't feel much better held together than my teens with their phones.

Also worth noting that a lot of the graphs (the ACT scores in particular) are constructed to show a downward trend but really seem to be measuring the COVID pandemic more directly.

The SAT and ACT plots indicate an accelerating downward trend beginning in 2018 though, later exacerbated by COVID.

That is exactly the bad analysis I was calling out.
If you take a data set and point out (while squinting) that it appears maybe to be turning down in the last two data points, any reasonable analyst should point out that those look like routine outliers and that if you want to project a trend you need more data.
Instead, you'd taking a very large (and well understood) signal in the next 5-ish data points and saying that it's proof of the trend. Which is silly.
No, that chart shows covid, period. If someone wants to show an uncorrelated effect across a signal that big, they need to come to the table with a lot more sophistication than a "WTF Happened?" blog post.

Exactly this.
I am convinced about the premise but for the love of god zoom out those charts.
