I think the drop is an almost worldwide thing and not correlated very much to disciplining. Disciplining varies, the screens and the slop are universal.

This is an interesting take. Based on what you’re saying, then I presume that in India and China academic performance is dropping as well?

According to PISA results, it seems that the US does worse on maths on average, but pretty close on reading relative to UK and Ireland.

There's probably a much better data source, but am on phone.

For the purposes of determining the effect of screen time on education, we would need to compare the performance of Chinese or Indian students over time along with a measurable increase of the use of screens and compare that to say American students. Simply comparing American students to Chinese or Indian students is not sufficient.

Yes, I agree, hence my point that this wasn't the right data. It was better than nothing though.
