Absolutely, we are feeding kids so much attention-span killing things. Even as an adult I'm having hard time with YouTube shorts, and i cannot imagine a kids brain having the ways to deal with all that.

That doesn't line up though. See if you're 13 and meeting the level in 2012 your scores don't decline. So the levels would lag a few years. The 8 year-olds show up and miss the mark in 2017 that indicate the infinite scroll problem was having a toll on them. Additionally this would start to show in class specific measurements (those kids with access to home internet, personal devices, etc. would have worse scores). I think the argument about social media has merit in discussion of children, but it seems more of a social distinction rather than an objective indicator for academic performance.

I wonder if there's research on short form but educational content or if that's fundamentally impossible.

For example I remember reading a lot of science magazines / articles growing up (granted popsci but for a kid it still teaches some things) and as I grew up things like the Economist.

Similarly I also played games like math blaster as a kid and have realized I need to intentionally provide games like this to my kids that ideally teach something (the bar being greater than zero learning) rather than playing one of those infinite running games or whatever.

I think we're probably talking about the exact same thing but am curious where content vs. short form media is.

Thanks for sharing :)

I certainly feel several degrees dumber than I did as a teenager without that stuff

Could we look at average SAT scores by year as a proxy? It's not a great metric because not all students take the SAT but I think there's some correlation.

Score changes look about the same across performance percentiles and ethnicities. That suggests it's a systemic issue unrelated to population makeup. While I'd be interested to see regional and economic breakdowns, it's certainly far from obvious it's a result of demographic change, especially after such a short period of time.

Mississippi is one of the recent education success stories though.

I wouldn’t be so sure. Anecdotally all the kids these days seem equally messed up. It could be that the Chinese and Indian kids are propping up the locals.
