Re: Flynn effect reversal - The article attributes this entirely to classroom technology. Researchers have proposed multiple explanations including changes in education, nutrition, cultural factors, and media exposure. The researchers studying the US decline noted "there is no shortage of theories in the scientific community, including poor nutrition, worsening health, media exposures and changes to education" and emphasised that "not every domain is going down; one of them is going up" - spatial reasoning scores actually increased.

Re: Denmark's "Solution" - The article states Denmark has "taken tablets, laptops, and computers out of the classroom" since the 2025/2026 school year with "undeniable" results.... however Denmark’s phone ban is set to take effect from 2026, and it applies to “smartphones and other private electronic devices with access to the internet" Critically, "this does not include computers and tablets that are used as part of the instruction.", and - the policy was only agreed upon in September 2025 and isn’t fully implemented yet - meaning claims of "undeniable results" are premature.

So much correlation presented as causation.

The article is basically a summary of Dr. Cooney Horvath testimony in the US congress and it is linked in the article. He talks about correlation vs causation in this part: https://youtu.be/Fd-_VDYit3U?t=134 There is plenty of research starting from 60's , introduce technology in the classroom and the learning goes down.
