I remember watching a video about this topic (sources in the description). The tl;dw of it is:

The content isn't the (main) problem. Its the format. The infinite scroll + short form content teaches you to be impatient. You could watch a montage of cat vids that cuts every 10 seconds and be fine. But have a tiktok style feed of the same content; having to swipe to see the next thing. You'll preform worse in cognitive heavy tasks.

Obviously its more nuanced than just this but yea.
